Mole Concept ADVANCED | Eudiometry | Dumas Method | Kjeldahl Method | Laws of Chemical Combination

0:01 both of you stand up and out fast Stand Up and Out

1:23 These are our four topics today. These are the four topics of today's class. With this, we will identify the percentage of nitrogen.

2:10 Both of you get up from there. Come here. Bus become Come here. you are laying eggs there come here Go. There is no desire to learn. These four are our topics today. Ok? Dumas Method, Gendol method, Eudiometry, Laws of Chemical Combination. So, we will start from here. then this Then this and then this. All this is about the value concept This is the part. Although different chapters

2:55 All these things are included in it. As Eudemometry of Practical Chemistry It is a part. Also comes in hydrocarbons. Tuomas method and Zeldols method all these Used in purification of organic compounds Are. But all this is mass percent nothing else. So like the question is

3:40 You have to tell the weight off 220 24 ml N2 There is an equation. I have to tell you the weight of 224 ml. What will be the weight of 224 mln2?

4:27 So removing the weight is not a great deal. What should I do first to reduce my weight? Can I take it out here? can remove moles Am. How many moles will come? 224 Bye Everyone is getting 224 ml bye 22400 ml But yes it happens but at a price so where will the mole go from ml to ml It got cancelled, how much did it cost = 1 * Power of 10 -2

5:14 Where did you go? Why? Come on son. 1 * 10 to the power -2 mol. Now if you have If I get a price then can you calculate the weight? what is it? How will you remove the weight? like i told you simply Go and see here friend. What kind of Panchayat do you want to do in your life? you friend? If I have one mole of N2, Is. Everyone's life matters to us. every From someone's life. self destruction

6:00 It may be there. when I don't mean that this kid is gone will be. He must have gone for some work. It is possible There must be some emergency. Everyone's personal region May be. what do you care? So I am not curious about this. Just have some majority in your life. every your nose and eyes in someone's life Stop applying it. This civic sense of Indians is dead here Is. Here civic sense commits suicide. Indians commit suicide. To them Everyone's life except your own is meant to. What is happening in whose house? Who is doing what? what's going on with whom Is? What is happening with whom?

6:46 Everyone. That is why 90 crore of us are on ration He is alive. Nobody is concerned about himself. Government will see. Bring this attitude into your life that What is happening in other's lives? What is the other one doing? This doesn't give you any It shouldn't mean that. I asked you if you ever came here before that what do you do? Where do you live? or this Ever asked which teacher for a teacher what does he say to you? What is the matter? I Don't care. The world doesn't matter to me From. Unhappy people do this. Will talk about others. of others We will discuss about it. what is he doing

7:32 How all these are characteristics of unhappy people. Whoever wants to find happiness in his life It is of infinite level, it has no meaning Who is doing what? Which type of people are frustrated all the time? Are? Those who care about the lives of others. Hi how are you? Hi what's going on? I miss you so much It comes. hey you bastard, you foolishly cares about your parents Please remember me sometime. Hi how are you? Hi how are you? Use to do it You donkey from somewhere. I have to find out its weight. so wait How will we get out? N2 is given. What would you do? 28 * power of 10. look this weight How do we get it out? How to Wet Will you take it out? It is 28 grams but in moles. The multiplication value is given. So what is the price of the price

8:18 Done? It became 100. It flew away. From here How much did the answer come? weight equals to kitna came?28 Gram. Ok? Now I will talk about the language of this question. I will change it. Now ask this question.

9:11 Solve all this by using a little bit of brain People. This is an easy question. It will be done easily. Where did Santosh go yesterday? don't laugh where did you go yesterday why were you in the room priyanshu had come why didn't you come what were you doing in the room so why didn't you come here I was feeling weak then Why was your head hurting? wow son wow to me in your absence sir It was hurting. Very sir my tomorrow.

10:00 ok let's say someone is having a headache And his duty is on the border and he says I am having a headache. I am not on duty I will come today. It will be accepted. So what's the problem here again? Good. So I was able to concentrate on the room I will solve it, I am able to concentrate today can you solve it? What a stupid question this is This is a tough question or Lappu, this is a question hey Lappu The question is whether this Lappu Question Lappu

10:47 Question is an organic compound which contains how many how much percentage ml is coming so what are you can you extract the weight of nitrogen You can divide the weight of nitrogen by total Weight Multiplication 100% answer will not come any ass will do it How much weight is coming? Weight of nitrogen.

11:33 Hey, I just got it done friend. What is the weight of N2? 28 grams. What have you asked now? Percentage of Nitrogen What would you do? Weight Up Total Weight Multiply 100 Percentage of Nitrogen How much weight did you gain? 0.28 , 1.18 , 100 So look, everyone look here carefully. How much is this approximately? 30 If this If it is 30 then how much is this? 120 increase this

12:19 crank it up. 30 / 120 1 / 1/4 * 100 Which answer is around 25? 23.7 These are all useless questions. This is the Duma, the Fuma, Geldol Welldol are lappu things. The names of these It's tough. There is nothing in these. Suppose there is another question here. I am Changing this question. let's see this much It doesn't come. It's coming to me 448ml and the weight of the sample is given to you 2 grams.

13:06 Find the percentage of nitrogen. Find the percentage of nitrogen. Easy Without getting upset. Ok. at ease at peace 448ml I am able to do it. What do we take out first People? Moles can be removed first. Moles = 448

13:57 / 2240 How many moles have come? 2 * Power of 10 You can calculate the weight here. yes, weight You can take it out. Wet How much weight will come from here? 2 * Power of 10 -2 * 28 yes and no brother solve this question quickly How much are you guys getting This will come to us in grams will come in grams Now what do we take away from here?

14:43 Percentage of Nitrogen How to get it out? 2 * power of 10 -2 * 28 / yes times 100 Is everybody able to do this? How much will it cost? 28% If any such question comes, you will ask it. One more Look at the question. Is an organic compound.

15:30 Organic Compound I have 1 gram of it. heat it up I got N2 after doing this. 112ml isn't it in this organic compound We are talking about the Dumas method. Dumas, all this, all this is just an application of Mole. Is. All these are the applications of Mool Calculate the The same mass percentage scene is there in it. Calculate Percentage of Nitrogen. Ok?

16:16 Calculate percentage of nitrogen. How many people responded? Everyone do it, it's a simple question brother How many students have the answer of 14% among you From

17:02 Answers of many have not come yet Son, first of all we will find out the moles. The Calculation of moles is 112 / 2 4 0 I'm just telling you one thing multiple times and still you people are not able to Understand the simple concept it's pretty Strange. First you will concentrate only on finding the mole. Take out 112/ 22400, how much will it cost once? Moles Equate

17:48 moles = 112 ml divided by 125 ml 22400 There is ml in every mole. This will happen. So Moll went up. ml to ml cancel Went. How much did you get from here? How much did it cost? 1/ 200 What can I say to 1/2 1/ 200? 5 * Power of 10 - 3 moles. Yes and no. If this is my There is a mole nearby and I need to take out the weight of N2. So how do I find the weight of N2? My It is present near 28 grams per mole. yes and No. With what should I multiply this? 5 * 10's So what is the value of mole to the power of -3 mole?

18:36 Swaha. What was saved? The village was saved. How many grams are left with us? Weight of N2 will come from here. Weight of N2 = how much is coming? 28 * 5 * power of 10 -3 grams divide by Now if you want to calculate percentage then wait up Total weight is it, weight up total weight multiplied by 100 solve it simply it is simple Now tell me how many people got the answer to this 14% how many people answered. how many

19:22 Hasn't it arrived yet? Just one. Yours also did not come. what's yours Name? Ashutosh, tell me your full name. Yadav ji, have you drunk milk and gum? We It's a simple question. Your reply is not coming. third this it is a similar type of third Question. Isn't this the third question? Hey son divide We have to multiply by . What do I teach in this To you? Duma method is Lappu method, friend. what do you do yes friend? How much weight is given? 28 * 5 * What is the weight of 10 to the power of -3? 1 * 100 How much percentage is coming? 14%

20:14 Yadav ji is welcome friend why are you You are hell bent on destroying me my friend All are together Why are you hell-bent on destroying I can make 1000 such questions. Write another one on Dumas method, is there any There is a concept and this time also whatever is not done Son, I am back in 11th Bio once again. Take it and see, or it could be someone else Try the subject an organic compound Is

21:00 What do you mean friend, what days have come here What times have come, it is an organic compound Heating the Charges is Alright When heated, you got 896 mln2 It had 8 grams Take out the percentage of nitrogen in it

21:48 Now you will not be able to ask this question if you solve it you mean nothing again Percentage of Nitrogen Everybody has come How much is coming? Yes 40 See, I have maintained everything the same. I have multiplied it by eight. to this also

22:33 Multiplied it by eight. I don't have to solve it at all. The answer will be the same. 1 gram 112 multiply it by eight what will be the result Will you go? eight multiply this by eight how much is it Will you go? 896 So it's the same calculation. Is there anyone who knows the answer to the first one? I went but there is doubt about it. The answer to the previous one had come. Now what Feeling doubtful? There is no one like that. Tell me, tell me. give it to me comfortably How many of you have people who There have been more than three drops? be three have been done. three and three plus

23:19 You know it's written on people's faces talk? That's why I was more worried about you guys I have it. I just need to ask I didn't know whose drop was three This has become too much. your old age looks Now. Please read it. to raise your children You yourself are roaming around like a child. No. No. I am right now I am papa's nephew. I am my mother's servant. Yes, I am grandfather's pot. Don't do all this. You guys should study hard. old age has come yours. The dropper is as old as it is There is less and less interest in the content Is. He thinks that studies are important to me

24:06 knows everything because these idiots know nothing It doesn't come. It remains completely in the air today. They It does not last. you guys ever see Wherever the dropper child passes, it will be known When he wore shoes, his shoe marks were left on the ground But he does not come. lives in the air. even if it comes to class It does not stay on the ground. this where the dropper gin gin has three meanings Three, three or four drops fell from beneath them You can take out the sword and axe easily. You won't have any problem with ease. Air In Let me solve this for everyone and tell them

24:52 I What will you remove first? Remove moles from here. will take 22 / 22,400 how much is the price tell me Ok, solve this and get the overall answer How much will come, 14% of all people is coming Answer Coming up to 14% Ok. Everyone has come. Ok. Accept this is the question.

25:40 Now look what you have done here. You have changed the temperature here. and the pressure has also been changed And then now you cannot simply divide 55 ml can you do it with 22400 ml because that Conditioning is done at standard conditions. Is Is it not so? So here is how to remove moles Which one would I use? n = p* v/ r*t Ideal Gas Equation pv = nrt When Things Change Please note that the pressure has been changed. Temperature I have changed it. Normally we are like this

26:26 It is said that on standard conditions We people the volume of one mole of gas how much does it cost? 22.4 litres. but here Condition is not standard anymore. Conditions Have become non standard. Was there music? Go and talk to me. Whose phone is it? No, don't show it. Just tell me whose Do you have a phone? spam.

27:13 You have to ring the phone to hear spam You keep it on me. Are? Which is the phone that you won't miss? wanna do it? as your phone rings Is. Hmm. Son, these days you see this OTT picture of India It seems like you hold panchayats in chat and i know who you are please

27:59 quit your job Do some good work in your life Will you move forward? Isn't it? that is saying sir Your only answer to personal mentorship I don't know. Take up some new work. near you There is nothing left in life. Please don't do all this. Will you be able to solve this? n=pv/rt Well, you tell me what is the pressure? Tell me the value of pressure.

28:44 Yes. Now listen carefully once. everybody here Look, please focus. In Dumas' method of estimation of Nitrogen 35 g of organic compound Give 55 ml of nitrogen collected at 300 Temperature 715 pressure. Now the pressure is 715 Nor does it release any amount of water It has happened. When you heated the compound So some amount of water has also been released. Is it okay? So that water also has pressure that which we call aquus Tension or water tension. How much is that? yes 15mm listen carefully how much it is What is the pressure for nitrogen I will say 700 mm HAG

29:36 And if I have to bear this pressure at an ATM If you want to convert then 700 it has come mmm what should I write in it I am 700 b mm of hg first we will learn this peacefully na There is no hurry to solve the question yes no that is a secondary aspect 760 what is mm of hg but ATM is ATM where will it go up is it there or not first take a look here comfortably drink it, it's not going anywhere We will solve this, how much will we earn Pressure from here to ATM What will be the pressure 70 70 / 76 atm

30:25 You can solve it further in whatever format it is If it comes, it will come to the ATM. Is it okay? and ATMs ATM Isn't it? If we talk about ATM, we will if we talk about So the unit of gas constant in ATM How much is it? 0.082 Liter ATM Kelvin inverse mole inverse know or not this is all oh so you must have read a little bit Or what else do you call 0.082? 1/1 Simply What will you say to this 1/1 So the pressure came on

31:12 Volume is given R and you will write this and the volume also in ml that In litres? In litres. Because you have its In which unit have you taken it? In liters ATM. Are you understanding? Put all the values. Remove moles. After mole removal What will you take out? Will you remove the weight? Extracting the Wet from the mass given after You will divide it. Is it comfortable? Easy It will happen only if you do it. Haste Organic The weight of the compound is given. in a hurry If you do it you will be destroyed. Why did they make the aqueous tension minus? Because this is not nitrogen pressure.

32:02 Whose pressure is this in that system? Water Of. So the pressure of nitrogen is the same Moles of nitrogen will come. water pressure If you find the moles of nitrogen from this then the answer is It will come out wrong. So I minus it Is. Ok? We will solve it easily. can solve this Are you? Look, now we will put the value here. Son look here tell me the value of pressure 70 / 76 The value of gas constant is 0.082 What will we write? 1/1 so where did 12 go

32:48 Will you go? Above. Are you understanding? 12 Write this above I gave 1/12 and the forest remained here. 12 Where gone? Above. Tell me the volume. How much ml is it? If you want to write in liters then 55 * 10 to the power -3 What is the temperature? Yes.

33:34 And I got these for him. Now, what else will we have to multiply this with? Wet To find this you will have to multiply by 28. What should be done to remove the weight? So Tell me how much will the weight be? 28 * 70 * 12 * 55 * 10 to the power of -3/76 * 1 * 300 and multiply it by By which number will the whole have to be divided? Yes which is the given weight of the organic compound. And then you will have to multiply it by 100. so it's a Pure calculation game. it's pure Calculation game.

34:35 We You have kept the volume, son, here the direct price There is a way to get it out as well So how were we finding the price directly Divide by Volume The volume of 1 mol at standard conditions which how much is a? 22.4 litres or 22400 ml The conditions here are not standard. Here The temperature has also changed. 300 Kelvin Is. The pressure has also changed. So both of them This is not ideal. what is the stp Condition? What are STP conditions? Standard temperature in pressure. what is the Standard temperature? Yes.

35:22 Standard temperature in pressure. STP Will you tell me once what are the conditions What is the temperature under STP conditions Yes And what is the pressure and at NTP How much it is, this is your situation Tell me, you're just sitting here Fill them once at STP temperature How much will be the pressure on NTP The pressure would be the same on both The pressure will be said to be 180m only but the temperature It is different. normal room temperature how much is a? 25°C or so what do you say? 298 Kelvin and Standard how much is a? Yes

36:09 300 Come on brother, you write it. I am nothing I will write. So right now they have to do STP i.e. Standard Temperature pressure and NTP means normal I don't know the difference in temperature and pressure. it This is the condition of the world. Let's see what the online people will tell us. this is it I am sitting with the answer ready. C will come. That's good, brother. so close-close There is an option. Anyway, a very tough calculation Will have to do it. What is STP and what is NTP? Just tell me right now We

36:56 So what is the temperature 0 degrees Celsius or 273 Kelvin Three This is 273 Kelvin

37:42 The syllabus of your test is based on the basic concepts and IUPAC nomenclature. So you will study the basics, every section, right brother? This physical becomes basic and inorganic The periodic table of organic has become You will study the basics a bit How much is it costing to solve this Which one is coming from this C option is coming So this is just a little typical calculation brother And someone asks this question in the exam

38:27 No problem. Now write a next topic. The Geldol Process I am changing the topic. what is the name of the topic Is? The Geldol Process Reldol Process In Geldol process nitrogen is in what form?

39:12 Does it evolve? Forms of Ammonia In. Is it okay? So, it is a good idea to look at such compounds. in which it is used for Along with nitrogen there will also be hydrogen. Nitrogen will also be there and who will be with him? There will also be hydrogen. Is it okay? Which process? Geldol Process. and in this, as in the Duma process In what form is nitrogen released? In the Dumas Process Say. In the form of N2. and the Geldol process In Yes in the geldol process Forms of Ammonia Then whose reaction is done with ammonia?

40:00 I have already told you about H2SO4. Now look here, what is written in the question? Read it comfortably. Ammonia is evolving. I spoke to them in English as well as in Hindi I have to take the question. How they spoil things while moving around, friends. No problem. Ammonia Evolve Means Ammonia is coming out. The sample is 75. Of the village. neutralizing it from 10 ml 1MH2SO4 Tell me the percentage of nitrogen. So take a look here carefully. Suppose it is NH3. there is no solution to this

40:45 Will do it. Stop right now. This is H2SO4. Ok? if a penny of it will be of use So how much of it will be useful? Yes. Friend who helped you pass 12th class? Buddy? I repeat the concept six times first I will get it done. I ask again for the seventh time. Then you give the wrong answer. If one pound of it is being used then how much of it Will the mole come in handy? How much should I say? Two moles. What will be made? of NH4 How many moles of SO4 will be produced twice? Two moles.

41:35 Good Price The price of H2SO4 is given here What is it? What is given? What is the given value of H2SO4 Is? Volume is given. how much ml did you give Has it happened? What else has he given me? Concentration is given. to remove moles How many ways are there? Five. Which one? Wet Up atomic weight. Number Apagadros Number Volume Up 22.4 Molarity Multiply Volume and PV/RT Which method will you use here? Molarity Multiply Volume. now the volume is in liters Given that in ml? How much is it? Tell me the volume. 10 ml then 1 *

42:22 10 What happened to this? 10 millimoles of it. Why? Because what's the volume in? Liter in or in ml? So moles and liters mean volume If given in litres. per liter * mol Liter is its price. but what about here is given? ml. you don't understand one Times. What did I say? m * v What did I say? m * v equals two What happens? Mole. now what is m? By the way mole per liter times liter so these cancel out If I went then I got a price but what would this m be it is priced at per litre but don't tell me what to do given in milliliters

43:09 So litre by litre flew away, who survived? and what will you call it, millimole Because milli and mole will remain in the units So what will we call it according to this millimoles how many millimoles are there 10 is visible. if it is 10 then how much is it will be? 20 ml Mole. Now if you know someone's worth, then his weight Can you tell me? What will be the weight of ammonia extracted here But? Wet of ammonia.

44:03 The answer has arrived. Hey, I am getting the price of that thing checked. First Class From then till the last class. just change the language It is happening. It is written above. take out the same It is worth it. How much weight are you gaining brother? 20 times We 20 mmol Multiplication 17 grams But remove the price and see how much the monsoon clouds are coming 340 Milli gram is milli and also gram How much is 340 mg That means milligrams. Convert to Grams

44:49 if you want to do it then 340 * 10 to the power of -3 Gram. Are you understanding? How much should I tell him? 34 grams. Yes and no. ok look at one thing here like NH3 If it is 17 grams then who all are in it? 14 + 3 Isn't it? Hey who has 14 grams in 17 grams? Nitrogen. Who is 3 grams? Hydrogen. So Is there all the nitrogen in 3 grams?

45:36 What is it? There is also hydrogen. of nitrogen from this How do I remove my weight? How can I find the weight of nitrogen in this? I? So what should I say, the basic thing? 17 grams In ammonia How many grams of nitrogen is there? 14 grams. Ok? So in 0.34 grams of ammonia How much nitrogen will there be? 14/7 *34 yes and no hey this is what I am doing wrong am i So solve it, I will keep doing everything

46:24 I am doing something wrong, please proceed further keep solving it will multiply by two What amount of nitrogen will come amount of nitrogen Yes 28 grams hey it's a matter of common sense friend 17 There is 14 grams in 34 grams. There will be 28 grams in 34 grams. grams is it correct, 3.4 grams will be 2.8 grams and 34 grams will contain 28 grams I don't even have to solve it, can you simply tell me If it is not there then only the weight of nitrogen will come Now what do I have to say here percentage Off Nitrogen

47:10 How will you get it out? Weight of Nitrogen Divide by weight of organic compound multiplied by 100 No? So what is the weight of nitrogen? Please tell. hey tell me Who stays quiet in my class. one day It hurts him so much. it would have been so bad Is. Why can't I tell? Even crows do not come to his shraddha To eat. His family members keep performing his shradh That our elders were people and died. Now the crows Till then he does not come to eat food. It is said that he was a finished man. what will we eat For that? Let's go somewhere else from there.

47:56 Good. So don't do such bad deeds that even crows have to eat them did not come. Yes. 28 by 75 Multiply by 100 What's coming? 25 75 would become 1/3 but a little less than 25 This is too much. So a little bit more than 33% will be. How much is coming? Exact Solve on doing

48:53 Everyone's done. I will tell you the process. Process You stand up. Stand up. you we you yes you Don't explain it to him so much that the sound can be heard here. Explain, there is no problem in that. These It is your good nature that you take care of others Do you help me? But don't act so fiercely Everything else will get disturbed. Help with ease Do that. Isn't it? Help me, but show me It doesn't happen like this, like four people Went to the hospital and got his photo taken with two bananas

49:39 Helping the patient comfortably Do it for him, he needs help So I made him sit here Go son, what will be the process in jaildol what will be the process Zeldol process i said so what i said what was an organic compound Organic Compound Who all were there in that donkey? Nitrogen and Hydrogen. So I accepted him as my saviour and heated him up. Did. So Haabu accepted it and then Babu It came out. What was Babu's name? Ammonia. Now What did I do with all that ammonia? Neutralization. Who did you do it with? Of H2SO4. Is Is it not so? So whatever its value may be

50:27 It will cost double the price. so when its me If I find out the price, what will I take out? From this? I will take out the weight. I will take out the weight. and what after removing the weight Should I take it out? I will take out the weight of nitrogen. Simply Its weight will not suffice. Then What will I take out? Percent of night. it The process happens. Although its direct There is a formula. But I'm not a formula Wants me to memorize it. hey how will the forest come what is in it You have to do nothing, take this NH3 Do the reaction with HCl, what will be formed? why NH4

51:14 It took one H+ and it became NH4Cl Hey Silence, please ask your questions properly. Now Who is with NH3? H2SO4 then tell me How many H+ ions will H2SO4 give? one or two? then give How much ammonia is needed to eat? Two. So there will be two uses. There will be double use. Satisfaction Only H2SO4 is used in the Geldol process. Why?

52:06 in the geldol process Only H2SO4 is used. Why? Can anyone tell me this? What is the reason behind that? Can anybody tell me? Because Any acid, when dissolved in an organic compound But if it works, it breaks things Is. Like who is in our body

52:52 The defence class is going on peacefully. Why Do you mess with her? You don't have to do anything. I am looking at Am. There is no problem. Useless You keep resolving it. problem resolve Zeldol method cannot be used for answer Will you tell me? a B C D. in the Zeldol process In what form is nitrogen released? Ammonia. So what should be in that compound? want it with this? Then What will be the answer? a B C D D will be done.

53:38 The Zaldol Method Cannot Be Used to Determine The Nitrogen in Compound with the Nitro Groups, Azo Groups and Nitrogen present in the ring because nitrogen in This compound cannot be converted to the Ammonium sulphate under the conditions at this Method. So whether it's a nitro group or not Whether the azo group is in the nitrogen ring Be presentable even if you don't have anything If there is no hydrogen then what will be the answer Its D ok write it down D will be the answer In this not n + h Here also there is no n + h and here also there is no N +H is not there. Look at this nitrogen

54:24 What is the valency? 1 2 3 and all three No bonds with hydrogen. Whose Are you with me? With carbon. If if there is hydrogen then it Oh dumb one. The idiots are completely finished. Son, this time I will check everyone's copy I will do this and the one who does not have this question I will beat you. Enough of your drama. You all are stupid idiots. Online people, you will get slapped online From here. Solve it in 10 seconds. Question in just 10 seconds. We just sit there to pass the time. Any

55:11 There is no leftist left in life. Double Who are the biscuits behind? Who is getting this cheat mill here? Yes Went ahead. He was eating biscuits sitting at the back You idiot. So I carried on further For them. Come on now whoever is right will do the most The one who answers quickly will be given a biscuit On my side. Who went? Who went next Which of you? well there they went I got biscuits brother Here it is This is 2020 Gold I have got Parle biscuits

56:03 Son, are you eating biscuits comfortably, tell me friend A option come here I will feed you biscuits you come quickly come quickly If the answer is wrong then Well you don't eat biscuits again what is this a gift for how much are you getting come come quickly Everyone is a winner, this is what is coming Whose biscuit is it by the way oh ho ho ho Come on, eat, eat, good luck to you. Oho Eat it in that. No no, I will not eat it now. come on, don't eat this and sit down quickly Now one more time. One specialty of girls is

56:49 Is. if the girls went to a restaurant Suppose no no we don't eat that much. no no please Where is the [ __ ]? And I will eat four rotis at home. Hey, you eat like this at home. This way Ok. The drama is also correct. here you go brother this is saying that we are We were robbed by our own people, outsiders have no power Our boat sank where there were not enough biscuits Here, grab the biscuit He is saying that I cannot solve it remained priyanshu is done son come here

57:37 Today Priyanshu will tell some stories from Bihar Anshu that's why I am calling him a place give me a place brother come son come well done come here can anyone tell a joke No why are you smiling and saying If you want to smile, he will sing a song for you Sing a song friend, all the kids are wanting to see it Are. it's rainy. Tell it loudly. Let me speak slowly. something Let him speak. Tell me friend. heard loudly Give it to me friend. Hey, let the poor guy start.

58:23 I have a sore throat. Why? He won't like it. You have to caress your throat It feels good. That's why I am saying this. Tell me. You take it easy. What, a little drink? What do you need, just a little bit, come here Loudly What Life is a beautiful journey where was the song 'what will happen tomorrow' in this hey guys something in the song There are emotions, there are some tunes, there are some rhythms there's some rhythm

59:09 There is no tune, no rhythm, still we are amazing. Come on, sit down friend, you sit with such confidence you have to keep it in your life don't sit We will prescribe you medicine no matter what the illness is If you die, you will die, go to hell Has everybody's answer come? who is priyam hey priyam Priyam is not anyone's name, who is Pritam? ok pritam Will any of you tell a joke? This class is becoming so boring. The Duma Method I know this in life, I prepare myself At that time, I used to read the page as soon as I saw it. hey don't read this bro jailol process dima so frustrating it is i hate it

59:56 With these things. But now I'm going to slowly I am getting comfortable. can anyone tell a joke is it one of yours? Brother, there should be co-curricular activities also. In school, you guys used to jump around and tell stories Were. Whether it is there or not, tell me the son, it is right. How many of you got 40%? what percentage would it be 20% how many people came Come on brother look here NH3+ H2SO4 Whatever is being made from that is being made. Tell me about the moles.

1:00:43 It has been said clearly. This time, someone There is no concentration. There is no volume. How many millimoles are given of it? Did you get 20 ml or not? Found it. 20 millimoles. So if this is 20 then this is a baby elephant How much will it be? If this baby elephant is 40 millimoles then how much can you estimate its weight 17 g per mole What happened to mole from mole, how much is milli gram Miliram 600

1:01:28 or 68 Gram The weight of ammonia is here. Now, the nitrogen can you lift the weight? How will you get it out? How much is 14 grams of ammonia in 14 grams of is there nitrogen? Sorry 17 grams. Sorry guys. I can make some small mistakes. How many Is there nitrogen? 14 grams. so how many In grams? How many grams will it be in 68? 14/7 *68 How much is coming? 56 grams Has everyone's arrival arrived?

1:02:16 Now what is the weight of the organic compound given? Has it happened? Someone will solve these questions completely Buddy. 56 / 2.8 * 100 How many people have come? Is this someone like you? Of those who did not come Any one who has not come from the original The answer to the concept is being read from the beginning hasn't anyone come Satisfaction Now you have come here, get up from there and come here Come come here Now you sing a song for everyone.

1:03:03 Do what you know. any anything whatsoever You know it. Nothing comes to mind. Why are your eyes getting red? smoking ganja are you there? Yes? I don't get complete sleep. Everything in life is incomplete, right? Sleep, dreams, hunger Tell me a joke. Come on, tell me your love story. is being

1:03:54 I'll have to tell a joke when will you learn If someone else spoke, I would have heard you being desperate Isn't it So is Priyanshu that someone? Call Priyanshu, then I will tell you. Look here, look at me for a while. You guys have to stand in front of the teacher

1:04:40 I don't know. So far I'm just checking this out Was. hey camera your camera is gone Buddy. I will break it right here. Cameras I was watching. Are you Modi that you are worried about the camera? You? Are. How is it looking in camera? are brothers Sisters. Ever since I saw this camera. A camera keeps watching me. Sister Jashoda kept telling me that on my side Look at me sometime, I kept looking at the camera. As such You will ask the next question. Now I'll give you the next question

1:05:27 I swear on aunty, you will die. you ill-mannered person Ask questions. This 20% has come for everyone stupid questions are being asked and still you people What is the meaning of your life friend of Let us go

1:06:28 NH3 + H2SO4 Now look carefully once Son What is Molecular Weight Factor equal to 2? Equivalence. So we have to take the plunge From here. because what you The concentration is given and the volume It is given, in what form is the concentration given Has it happened? n / 5 what does n / 5 mean Has it happened? Normality. So normality If we want to convert it to molarity then Nani = x * m then how much will m come from here n/x Is it there or not then how much is n given n /

1:07:15 What does 5n / 5 mean 1 / 5 * n and what is x so what is two 1 / tan 1 / 10 because m is multiplied by the valency factor So what is the equivalent of 1/10 mm in 1m? This is 1 mm and you can make it 29 how much say say 30 so that it can be solved fast, don't do it You have simplified all things I did it. NH3 + H2SO4

1:08:00 is forming NH4 twice as much as SO4 Ok. the answer has arrived How much is coming? Great. tell me tell me. H2SO4 What does 1/5n mean? 0.2n And what is n equals two? x * m n how much 2n = 2 * m then what will be m?

1:08:50 1m This is concentration 1. The concentration is 1. What is the volume? 30 ml then 30 is divided by one If you multiply, how many millimoles will you get? About 3 mmol. And if it has 3 millimoles, then how many of its Will it be millimoles? 6 mmol. So if it is 6 millimoles then what will be its weight Its? 28 * 6 Sorry 17 * 6 mg mg. Ok? Then you remove the nitrogen from it.

1:09:36 You can. There are 14 grams in 17 grams. How many grams will it be? How many grams? Then you can solve it by dividing it. How much did it cost in grams? Ok? Let it remain 102 mg. I can solve mg also. 17mg How much is there in it? 14mg So it will be in 102 mg. Solve it. how much Used to be? 84mg is coming up. Convert it into grams. how much in grams Will be done? 84 * 10 to the power of -3 in grams, this is it

1:10:24 Went. What is the total weight given?5 What will you multiply? 100 This is what I will do. 84 / 5 84 / 5 so 84 / 5 has arrived. then 84/5 How much is it? Yes So I have approximated it, uncle. 30 has been changed to 29. Meaning 29 has been made 30 for simplification For. How will the exact result come? I kept the value No, for exact simplicity.

1:11:12 Hey, are you able to solve this? Let's look at another such question. 5 grams you have an organic compound. Let's heat it up and make it react with H+ Are. Isn't it? So the NH3 that is released,

1:11:58 It is able to react with H2SO4. How much H2SO4? 10ml2 n Find the percentage of nitrogen B option is coming. That's fine with him. So do it Son, first of all everybody should keep this intention

1:12:45 Do it or I have to ask the question. you guys You make me loose my intent. first question You think that I won't be able to write. Then that does not happen. you will keep the intent right Even if I want to do it, that will still be a question. Many of you play cricket You must be watching. When in cricket the ball is ball many times It is going very fast towards the boundary The fielder thinks that I will catch this ball He can stop me only if I try to stop him. he thinks of that if she doesn't stop then he would have been shocked Is. So keep your intent a little positive that I want to ask a question. It will not happen without intent. It will not happen without intent. Pawan Ye I am answering your question as well. I You are saying that I don't ask any questions I am able to do it. that's why you can't do it Because you are not showing the intention.

1:13:35 People even took it out. Now this 2n is given. If I get from here If you want to find millimoles then how many millimoles Should I get you out of here? millimole first look at me We will get equivalent from here. so got it How many equivalents did you get? 2 mil Equivalent Mol Th Valency Factor What is Equate Two? Equivalents would have been Are. Just say this millimole. if you got this If it is equivalent then it will work in millimili. Then everything became x. The valency factor is two Went. How many are coming? Two. So millimole How much did it cost? How much did it cost? Millimole one arrived. So if its millimole is one then the amount of ammonia

1:14:22 How much is millimole? Please tell. hey say it louder 2 millimoles Can you measure the weight, how much is the weight coming Please tell 2 * 10 to the power of -3 * 17 grams did this come in grams or should i simply what should I say 17 * 2 should I make it 34 mg in milligrams I can say no to 17 mg

1:15:07 what should i say how much n is there in 17 mg n3 If it is 14mg then how many mg are there in 34 mg How much will be 28mg no what convert 28 mg to grams Power of 10 - 3 grams percent of nitrogen take it out Weight of Nitrogen Divide By What is the weight of organic compound multiplied by 100 Weight 28 * 10 to the power of -3 * 100 / 5

1:15:53 are you able to do it? How much is coming? Nothing is coming. 5 or 56% Yes percentage of nitrogen will come. 56 56 no will come.56% Yes 56% Yes 56% Very good.

1:16:40 So the Duma process happened jaildol process is done write one Eudiiometry volume titration Volume Anu Measurement. Is it okay? In this, you can add any organic substance or any hydrocarbon Will burn it. Can we convert hydrocarbons into carbon? Do you burn it? The number of vehicles on this road It's going on who is she burning? to the hydrocarbons. What is petrol? Hydrocarbon. What is diesel? Hydrocarbon. LPG hydrocracking.

1:17:26 CNG hydrocarbons. Isn't it? diesel, hydrocarbons, kerosene, hydrocarbons, Gasoline, hydrocarbons are all carbon and Made up of hydrogen. by which we People produce energy. So let's assume hydrocarbon is CX Hy Now whom do we burn in eudemometry do? Tell someone to come along with you then You will learn. You guys are mentally challenged in this class You are not even present. so where you guys are your focus for a fraction of a second It goes away, the content goes away. then you You keep holding him. who are you burning Are? to the hydrocarbons. whose formula What did I say? C-X-Y Yes and no.

1:18:13 so I any hydrocarbon Which could be what? It could be petrol, It could be diesel, it could be kerosene. If I burn oxygen I have What is made in? CO2 and water. This is made. Ok? Now consider this hydrocarbon What is the formula? Its formula is px-hy Is it okay? And me I am getting its reaction done through O2 so CO2 and water are formed.

1:19:00 Now understand carefully. Suppose I am CXHY holder How much mole of hydrocarbon should I buy? 1 Mole. So how much of it will be useful? then it will come x + y / 4 mol. And how much will it cost? So it will form x moles. And how much will it cost? y/2 mol. Ok? So what will you say? txhy + x+ y/42 Forming y/2h2

1:19:49 Got it, suppose I buy 10 of this How much will it cost? How much will it cost? x + y / 4 * If I have taken 100 moles for 10 then I will write 10 moles Over there. First, we multiplied it by one. 10 I will multiply it by . x * 10 mol. y / 2 * 10 mol. first multiplied by one Station. Now I will multiply it by 10. accept it I will buy 100 rupees of this. Complete the equation. Complete the equation fast. complete the equation fast

1:20:36 Everybody do it quickly So what will you say while multiplying by 100? will give x + y/4 * say na y / 4 * 100 mol Beta udiometry Practical Chemistry Practical chemistry is a part of But this is also a mole and y / 2 * 100 Mole. ok suppose i'm here which are gases Gases Moles of a substance are decided by its volume. We say volume divided by 22.4 So let's find the volume. So accept it

1:21:21 If you take its volume instead of mole Took it. Suppose you took this vl how much ml Did you take it? So how much do you need of this? So The same x * y/4 * vml and how much will it make? x * vml and how much will it cost? y/2 * vml Assume that I took it Took 10 ml. So how much is this? x + y/4 * 10 ml and this Let x * 10 ml and this y/2 * 10 ml be 1 litre sorry if I took 10 litres then how much would it be

1:22:08 Will you go? x + y / 4 * 10 liters and how much is this Will be done? x * 10 litres and this is y/2 * 10 Litres This is the eudeometry. Is it okay? Such different questions Can be made. Well, there are a lot of questions Can be done. Let me ask some questions once.

1:23:00 Done. Everyone took note, right? Let's say you have propane. Took one mole of propane. Isn't it? Used O2. CO2 is formed, H2O is formed, Tell me how much will each item cost Son? Values ​​like X and Y are hydrocarbons

1:23:46 So you wrote what is the formula for propane? It happens? C3H8 so here the value of X How much will it be? Three. and what is the value of Y will it be? Eight. Isn't it? So whose number is X telling? Is? Carbon number. And who is y referring to? Hydrogen number is it? These are the x and y. Ok? How many moles of oxygen would be needed? Has everyone arrived? How much? x + y / 4 y / 4 Moles of O2 are required.

1:24:31 Ok? Because it was multiplied by one mole. So What does propane contain? These What is the value of x? and the value of y 8/4 O2 mol. What is 8/4? 3 + 2 how much Done? How many moles are there? Is it okay? well how much volume of O2 to extract will be? 5 * 22.4 litres. Yes and no. So how much O2 volume was removed?

1:25:16 How much O2 volume has arrived? But vehicles normally use O2 Not there. There would have been a ventilator in front of them No. It just sucks in air. Oho Vehicles only pull air. So Air How to find the volume? What is the air volume always? 5 Times of O2 Vol. Because in the air What percentage of oxygen is there? 20% So it will become five times. so how much is it Will you go? Now 5 * 5 * 22.4 litres. Because what is 1 of air? hey so You must have read Breathing and Exchange of Gases contains 20% oxygen We are 21. Congratulations very much

1:26:05 I wish you much. ok did you guys get it out from here did? x How many moles of XCO2 will be produced? Tell me 3 moles and that How much will everyone get Y/2 What is the mole of Y? 8/2 becomes 4 Mole same question if i ask you the same Question There is 1 mole of butane.

1:26:51 1 mol butane. Now tell me the moles of O2, CO2 moles, moles of H2O. What is butane? C4H10. I have arrived So tell me how much does one O2 cost Are? Yes Butane is what? C4H10 How much is coming?

1:27:38 6.5 6.5 moles or 13/2 is the same thing. of CO2 and his Yes Is this happening to everyone? Assume it is propane. It reacts with O2 and forms CO2 + H2O In this reaction we took 10% of propane ml So take out the volumes of everyone else.

1:28:28 Remove the volumes of everyone else. Yes. 6.5 4 and 5 I told you simply multiply by volume Let's solve it by doing this. Isn't it? How much will this cost? x + y / 4 * 10 ml2 yes or no You can solve it. What is the value of x given Has it happened? Three y values 8B Multiplication ml how much ml ok how many ml is this

1:29:16 Yes x * What is the value of 10 ml co2 x 3 * 10 How much is it there or not and how much is it is everybody getting 40 ml of H2 Write the next question, did you take this tip? The people The question is a hydrocarbon. One is a hydrocarbon. You took 5 ml of it

1:30:05 And you guys are burning it. CO2 + H2O On burning it 25 ml O2 is required. Need O2. This is making 15 ml So name the hydrocarbon. Which is a hydrocarbon?

1:30:50 This is a question asked in JE. ask like this Let us take the question that what is the name of hydrocarbon Tell. Sir 6.5 mol How did you come? If x + y/4 then the value of x is 4 It will be. Yes. So 4 + 10 / 4 adds 2.5 to 4 So 6.5 will not come. He will beat me right now. Did you understand? This has to be reversed. Now that The question has to reverse itself. What Tell me will you do it? For whom is this 25 ml given Is? what is this? x + y / 4 * Do you remember 5 ml or not friend? Multiplication by ml

1:31:36 It happens. Who does he have to compare him to? 25 of ml. And what is this? x * equals 5 ml 15 so the value of x is gone from here to my If the value of x is three then the value of y is Find the value of y from here take it out What is x 3 + y / 4 * 5 = 25ml can you solve this show me show me once Like I solve it. 15 + 5y / 4 =

1:32:23 25 5y/ 4 = 10 5y/ 4 = 10. Then, y = How much is 10 * 4 / 5 coming? 8 then 3 and 8 This is what it is, right CX Hy The value of x will come from here. The value of X How much did I take out from here? Three and Y's Found out the value. So has this arrived? C3Hz Yes and no. so the hydrocarbon is the Propane. Now like this is a question asked in JE. Exactly like the one I made. just it People also make similar questions. See these people copy me

1:33:25 You copy me a lot, I explained this much The bastard doesn't agree How much ml of hydrocarbon did you take? 10 ml I told you this is my hydrocarbon CXHY + X + Y/4 O2 forming XCO2 + Y/2H2 So what will happen? How much of it if it is VML How many ml will it be? X+Y/4*VML and How much will it be? X * VML and how much will it be? Y / 4 * VML is all solved like this. it Vimal is not there. Vimal Vimal Vimal Vimal speak Juva Kesari this V is ml. Isn't it?

1:34:10 The donkeys are giving out short forms somewhere. Vimal Hey, we don't eat Vimal. Tuberose we eat it This concept is valid only for alkanes. Who said that? It will be applied everywhere Babu. All You have to put the values ​​of x and y in this place. donkey He talks nonsense. iv How much is given in this? 10ml So what will you do? x + y/4 * 10 ml here x * 10 ml and here y/4 * 10 ml Is there any given value? How much is this given? 55ml2 and 40ml

1:35:00 So how much is the CO2? X * 10 ml equals how much? Value of 40 ml X How much will come from here? Four will come. How much is X Have you arrived? Four. Can you take out Y? hey can you take out y from here right? How will you remove y? 4 + y / 4 Multiplication It is not just 10, how much is it, multiply 55 by 10 40 + 10y / 4 = 55 make a minus

1:35:49 10y/4 equals 15 10y = 60 equals y 6 so C4H6 It will become C4H6. It's simple. This is a very simple question, anyone can answer it So. How many people answered this? very nice. Well, this is enough for today. One

1:36:38 Ask the old question. I am getting some old work revised. Then Will read further. laws of chemical combination In which there is purely theory. 5 moles of AB2 How much weight is given? 125 * Power of 10 -3 and 10 moles So what will one mole of AB2 be equal to? hey will you divide it by 5 friend, 25 * 10

1:37:26 to the power of -3 kg veggie whatever and 1 mole of it A2B A2 B2 1 mole 30 * power of 10 -3 What should I say from here? what can I say to a2b2? 2a + 2b = 2a 2b 2 = 2a 2b 2 30 * 10 to the power -3 And ab2 means that there is no ab2. ab2 boob strap-on Give it a minus. What is the value of 7 minus a Went? 5 * 10 to the power of -3 then find B

1:38:14 From here. How much will be the answer? Hey, anyone can do this. I told you about it yesterday. I did not tell you about the question A B2. Tomorrow. There is a similar question back. it What should I reply to this? A B C D These are such old revisions. keep writing topic Do their old revision again once. The old revision has been done.

1:39:01 Now write the next topic Laws of Chemistry Combination. The Lodge of Chemical Combination laws of chemical combination Write the first law. The Law of Mass Conservation. No It is purely a theory. There is nothing in it. I will look at the question now. What is the first law to write? law of Mass Conservation.

1:39:47 The Law of Mass Conservation. Ok? Write down what is written. what is written? matter is nowhere created Male destroyed in chemical reaction. so total What is the mass left? Constant. assume like

1:40:35 You heated calcium carbonate. If so how many grams of it is? 100 grams. So How many grams will the CaO and CO2 that will be formed be? will form? Of 100 grams. then mass never It does not get destroyed. The example is written here. See for yourself. If 10 g of hydrogen and 80 g of Oxygen will react and form water What is 10 and 80? 90 then the weight of water How many grams will it weigh? 90 grams. This is the last class of mole concept. Is

1:41:21 No? It is done. Now get nine more questions done in the last one. I will give it to you. Let's see how many are there out of nine Yours are right. How much did you guys learn did. Done? The Law of Mass Conservation. Total Mass what remains? Constant. See the next law. Law of Definite Proportion Definite Proportion This is also called the law of proportion. steady the law of proportions that in a chemical compound the same elements in a definite mass ratio There are. No matter how they make it. Isn't it?

1:42:09 Let's talk about mass ratios. Whose in this Shall we talk about it? of the mass ratio. Let's talk about the mass ratio. What is written here? water which would have been There are two parts in it i.e. 2 grams of which It happens? of hydrogen. and whose 16 grams It happens? Of oxygen. Now he wants water Whose is it? be it rain or laboratory yes. It doesn't matter. Mass Let's talk about ratios. what ratio Let's talk? of the mass ratio. that in this Hydrogen is 2 grams. what is the first one Was? The Law of Mass Conservation. What is a second? The mass ratio is constant. Isn't it? Definite proportions. hey which ratio?

1:42:57 How can you make it? You can make it anywhere. Water What will happen in? This is an important term. Mass ratio. Isn't it? talking about weight ratio my. Mass ratio. No matter where that water is from? It may be because of rain. No matter where it's made For him? It may have been made in the laboratory. Look at this. What is this? There are multiple proportions. What is this? Multiple proportions. Now in this Many people face problems. I understood what is this? what is written? When to Elements Form more than one compound. assume like

1:43:44 Two compounds are formed from carbon plus oxygen Can be done. What all can be made? also become CO and CO2 can also be formed. Ok? the masses of one element that combine with the Fixed mass of other element in a simple Ratio. Now look at the example once. Such as CO If yes, then what should 12 grams of carbon be combined with? Used to be? 16 gr. From oxygen. and in CO2 What is 12 grams of carbon being combined with? From 32 grams. then the mass ratio of oxygen How much is there here? 1 2 if anything further If compound is formed then how much will it be? 1 2 3 4 5 6 Is it okay? Brother, this is carbon. carbon is I have fixed it at 12 grams. here at How much oxygen did I take? 16 in one

1:44:29 Gram. How much oxygen did one take? 32 Gram. So what did you make of it? CO What is it? made? CO2. then find the ratio of these two 16 and 32 is 1:2, so I have fixed one Given and is a variable, then the element which he is doing very well whatever his mass is It always happens in simple ratio when you When you are making more than one compound So earlier what was the mass ratio? Earlier what was the mass? is there conservation or not then any one Mass of different elements in a compound Ratio Ok? Make it from anywhere. What happens? Beans. Make it in the lab, no matter the rain. Then What is this? Two compounds differ-differently We are making it. You fixed one,

1:45:14 Another change is taking place. So the second change It is happening, right? What are its masses? Are in simple ratio. such as oxygen Made from CO and what else? CO2. So in one How many grams of oxygen were used? 16 Gram. How much did one use? 32 Gram. So what was the ratio? 1:2 Are you understanding? Then there is the matter of mass in this. Look Ahead Law of combining volume which is called Gallusex Law. When Gases React They Do So in a Simple Way Ratio of volume. look at this lodge

1:46:00 It is very ancient. These are year old laws. This is very much It is written in simple language. and the volume of the gases in simple Combine in ratio. they are like Let us understand this in Hindi. When two gases reacts then a simple volume in proportion. Now look there is mass mass mass There was a discussion going on about it. Who are you talking about here Is? Now about volume. and if The product is also gas so that too is a simple It happens only in ratio. like what did you write Has it happened? 2 liters of hydrogen gas plus 1 liter What is made of oxygen? 2 liters of vapor 2 liters of hydrogen and 1 liter of oxygen What is the ratio? It is a simple ratio. Ok No? Like this can also happen. This could also be Is. For example, suppose it is written 2.4 and this How much is written? 1.2 so ratio so It is simple. What is this ratio? 2 1

1:46:49 Is it okay? Combining gases Which we call Galax Loss. The next Avogadros Law would be equal volume When the temperature and pressure of all gases What are beans and how much are they 22.4 How much is 22 moles in a liter? Of 1 mol. But if you change the temperature and pressure If you do it then the volume will not be the same in that case will remain. Or would you say that the volume of one mole is 22.4 cm It could be more and it could be less Is. What is happening at the moment? Avgadroz Law

1:47:35 What if that is a constant? What are you PNT? Constants Constant. So we can write Avogadro's law. can we? that at a fixed volume That volume represents the number of molecules Decides. or the volume is what directly proportional to moles Is. Say anything. So we call it this let v1 / n1 = v2 / n2 or else we What can we say from here? v / n = Constant. V / N = Constant. Whose law is this? shock

1:48:22 Rose Law. V / N = Constant. What is V here? Volume. What is N? Mole. So what is always the ratio of volume and mole? does it remain? Constant. what do you call this Are? Avgadroz Law. v/n Is Constant. then v1 / n1 = v2 / n2 Suppose I asked you here. How Can you ask questions to Lappu? of oxygen Given the volume of one mole is 22.4 then 2 Tell the volume of the mole. because its very old Is it lawz? Very old. Today we use them

1:49:09 Don’t even do it. So we will put v / n v here /n How much will you say here 22 / 22.4 / 1 = x / 2 then what will be the multiplication Will you go? 44.8 Liters. So what is v/n equal to? Constant. What do we guys call this? Avalanche Ross Law. Now revise it once.

1:50:20 Revise it. once again a half question do. V/N is constant. V/N Is Constant. Of Volumes and Moles The ratio is the same. If what are the beans? Pressure and temperature. Let's assume that in your exam, the question has come 208 Na The weight of BaCl2 is given

1:51:08 There are many questions like mole per 208 grams It is common nowadays show it by looking at one I am getting it done just for revision. Then I will do nine more questions once more. End I will do it son. BaCl2. Heatsink XH2. Now let's talk about some percentage Has anything happened in this? no percentage talk No. What's left? 8.52 g BaCl2 So you have asked about water molecules. This I The question has been created using AI.

1:52:03 This question has been created with the Help of AI. now you guys use your eye do it. NI Natural Intelligence. which is almost in minus 10 gms off took a sample of it What is left of 8.52 grams? BaCl2 so how much water was there in it? the weight of water equals

1:52:52 We Equ 1 point And if you want to find out the price and weight of BACl2 8.52 And if you want to find out the price do it, divide it, the answer will come divide as soon as you do

1:53:48 1.48 How much is bye 18 coming? 0.082 And how much is it coming for? Hey, 852 has to be divided by 206. 0.0 4 So what is the ratio of moles of both?

1:54:35 How many moles of water? two times it is In comparison. Try dividing it. How to solve such a question? See. Molar mass of BaCl2 anhydrous is 208 This is what the mass ended up being. molar mass of Here it is. So find out the moles of BCl2 from here For 0.041 moles of water, take out 0.082 Ratio of water to BaCl2 is 0.082 / 0.041 so What is the ratio coming to be? Two. It means N What is the value of? Two. Because of water's The mole is double that of VaCl2. work out the ratio It is his. So 0.082

1:55:22 / 0.041 then 2 will become 1. Means as much BaCl2 Who is her double? Molecules of water. Finds out from the mole. Yes. This was the most important question that I didn't tell you And even if you did, you still I have brains. found out the ratio of moles of both So how much is coming? 2 1

1:56:08 Meaning how much is BACl2? One more and how much is it? Two. So a BACl2 with 2 H2O will give the quantity of X How much value has gone out from here? The value of n Two have come.

1:57:06 Come on, write it now, I am telling you the last question. End The class is over. Last question means there are nine more questions. Just do this, it means you are at least confident yes you can attempt the question Atleast.

1:58:04 40 ml ethane That reaction takes place with oxygen. Meaning combustion is taking place. Find the volumes of H2O and CO2. in ml It has to be calculated in ml. what will you put? cx

1:58:49 hy What is the formula? CX-Hy+ X + Y/4O2 forming XCO2 + Y/2

1:59:36 Son Kunal will be like a question We will solve it tomorrow, only percentage is percentage were doing it from is there any answer coming ethane is what is the value of x for ethane it occurs and y are you able to do it How much ml? Tell me what will it make? These How much is XCO2 X? 2 80 ml and how much is this will form? 100 Are you sure? Y/2*40

2:00:22 Hey, tell me. It is butane. Its reaction is being done with oxygen. These It is 50 ml. Find its volume.

2:01:17 x + y/4 equation What will you do in this? x+ What is the value of x? and this 10/4 * 50 So how much is it? 6.5 * 50 means 65 * 4 Plus Yes, this is what will happen. Oh, it will come How much reply is coming? 320

2:02:06 Ok. I am writing it here that you should leave him for one year. Now! On heating an organic compound N2 found and its volume at STP is given by 448ml The weight of this organic compound was 2 grams Find the percentage of nitrogen.

2:03:07 The volume at STP is given as 448 ml then 448 by 22000 400 What will you take out from there? By how much will you multiply? From 28. The weight will come. How much? how much are you weighing Used to be? 448 / 22400 * 28 * 10 to the power of -3/2 grams multiplied by 100 This is what we will solve. How much is coming? 20

2:03:56 And is it coming or not? Converted all this into grams. Gram In In Zell process NH3 is. its reaction It is happening from H2SO4. Its 10 ml. this 1 It is ml. All this was found from an organic compound Whose own weight was 2 grams. Percentage Take off the nitrogen. Everyone got 28%. very nice. 325 ml Everyone's gone. Everyone is getting answers.

2:04:48 How many millimoles of H2SO4 are there? So how many millimoles of NH3 will be there? then NH3 How much will it weigh? We 34mg Isn't it? And what will be N2? 28mg Or what will be N2? 28 * 10 to the power -3 Gram. I have to find out the percentage. How to Percentage Will you take it out? 28 * 10 to the power of -3 / 2 * 100 How much did it cost? 1 How many people responded? 1.4%

2:05:48 FeC2O4. This is both mole plus redox Is. It is KMnO4. It is H+. I bought two for it. Find out its value. Last question: Six is ​​too many. not much Getting it done. Number of electrons in 2.2 grams of CO Tell. Come on, let me write it down. It is O2. 3.2 grams

2:06:35 Find the number of electrons. I am giving you everything in simple terms. Absolutely N2 is given. There is a compound. It contains 2% calcium. tell mm

2:07:26 2% of a compound is calcium or not calcium CA Its minimum molecular mass has to be told. Calcium Next Chapter Your IUPSC There will be nomenclature. just a practice You will get more problems. Do that more. NCERT has to be done word by word. NEET's I have to do PYQs. JE's

2:08:12 Have to do PYQs. JE Advance has to be done. Everything has to be done. There are eight questions. Eight out of eight should be correct Everyone. Is it okay? That's it. All of it is done. Hey, talk quietly. why is it driving

2:08:58 In old age?
