12th Practical Do & Don't || Q&A || Maharashtra Board #class12thboard @a2zpractical991

Hello Bachchan, how are you all? I think you'll definitely want to watch the radio chat practicals of your life, which are full of amazing moments. So Bachchan, about today's sessions. Basically, I will be asking you questions. How did your practical exam go? Matlab, did you enjoy giving the practical exam? Are my videos becoming too effective for you? We will discuss all these matters today. And if any child has any doubt whatsoever, No doubt, we will take it here. So what, if you leave me, I will keep sharing sessions with others. I can be of great help to you. Since you will be sharing the sessions, It will go to many children. Alright, let me just go ahead and do it quickly. I'm also a bit tired of this session I share it with my children. The children who want to touch me can touch me. Takki has brought up many of their doubts here. Alright, many children are arriving late. I don't know if he makes a profit. Because I can't connect with him one-on-one. And many children come to climax very quickly. Alright, let's begin this session. That is, what do you have to do in the practical exam? Or don't you have to take your practical exam? Since I'm also going out as an external person I am also looking here and seeing What mistakes do children make, and what mistakes do they not make? What you should do, and what you should not do, Should you feel nervous in front of outsiders? You shouldn't feel nervous. Today we will discuss all these things. Keep you connected to this session And you want to join me. Alright, I'll quickly collect all the kids' comments. Sahil Gunjal, sir. Same video, sir, start right away, sir. My PCB practicals went well because of you. Thank you, thank you, little Suhan. How to perform titration calculations? Sir, I scored 60% in the prelims. Rupa Rail College, PCMB is a very good student. Alright, sir, Class 11, sir, Please provide some information technology viva questions. Sir, how should I write the papers, sir? Sir, I need a sonometer I have the practicals for the annual constant, what should I do with them? Have you seen the practicals of sonometers? Very easy, nothing too hard in the sonometer. You can do it annually, then. You have to put the V8 directly there. Alright, so whatever doubt you have beforehand Let's do one thing, handle the sessions very thoroughly Share the group with me, so that I can access it from here I can connect with many children and with those who I doubt I can solve these sessions for them. Please share this with you. And I, I am here to take comments from one child What are you doing, start it. Come on, plenty of The children have already joined me here. Today, we will see How is your exam going? for 12th class. Every single child You can ask me any doubts by commenting here. Sir, 12th grade chemistry experiment How to do it? 12th Chemistry The experiment is very easy, kids. You just need to I need to perform a titration. One titration You did it, you'll get confirmed right there with 10 marks. There's nothing in titration. Is there anything at all in it? You don't need to do anything in the titration. Which titrations will come? The more colleges, the better the titration Here is the child, that one is Your KMnO4 vs Mohar Salt Which one? KMnO₄ vs Mohr's Salt titration That's too much. Mohar Salt means FAS. This one here. The one you're doing titration on is happening, whatever is happening to you The titration is going on, isn't it? I'm watching it. I am keeping it in the exam. KMnO₄ vs Mohr's Salt Mohar Salt This one here They are keeping the titration too long. That titration, those people You're keeping it too much. You need to perform this titration and then leave. Yes, titration is important. you need to perform the titration Total marks: 10. 10 marks So many children say, sir, what all should I write? There's nothing to write, I need to write the aim Directly go to the observation table observation Come to the observation After that, you need to write observation table. After that What should I write? Observation table. And again calculations Calculation And then you'll get the result. Come on. I'll tell you a funny story. A funny story. What is it? Listen carefully. Look here. What are so many children doing? They are doing everything very well. But they Calculations and results are causing these errors. Even in that calculation, they are making mistakes. My result is that many children have not written much. You will get results in every practical. mention the result. If you have not mentioned the result The child has lost one mark, hasn't he? Just now, when I went outside, the kid listened to what I said. Just now, wherever I went externally What many children have done wrong here Everything was done correctly. They forgot to write down that one thing about the result. Checked 50 copies in the ledger. about The results of 15 children have already been declared. So, one mark. I had to cut him there. The other thing. The child is most nervous in the midst of the storm. Brother, I'm serious, No way, I'm not a cheetah who will eat them. That one, the external one They are coming here, even though they are mistaken. Just as normally questions Hi, tell me the second name of FAS What happens? It's easy to say, sir. They call it Mohar salt. No, even there, it's the same. I'm confused, I'm nervous, anything goes now. Whatever are you going through? No, you're not nervous. Here it is, completely relaxing your mind Give it to me, very relaxed. Outside as well a teacher like you, sir They study in your colleges. Not nervous, if You will become nervous. Your heartbeats will quicken then you You won't be able to get answers to any questions here. That's why I'm telling you not to bother with these things Very good, remember first, you I'm completely nervous here. Just tell me about physics, sir. Sir, tomorrow is biopracticals. Sir, which place is external? Do you need to sign it? Sir, which place? Sir, chemical What needs to be done in kinetics? Chemical kinetics. Also tell me about physics, sir. Please tell me about physics as well. Hello sir, can you please tell me if you are external? M.K. Junior College Have you come here? Yes, M.K. Junior College. Sir, acidic Are there 6 marks? Yes, the acidic radical you have, isn't it? I've already told you about titrations. What all needs to be done and what all needs to be done No, don't do it. This is for the viva. Ask away. Take the viva questions for it. First.ValidationError What is meant by titration? What is titration? What is titration? They are directly asking all these questions. No new questions are being added, nor are any being included. These are all the questions these people are asking. Any other questions? Naya is not being added here. They are asking you whether What is your indicator? Indicator Which indicator do you use in this? Even the indicator itself may deceive you. Third, I have questions for you here They are saying that colorless Colorless for colored ones Which meniscus do we see? Which one? Do you see the meniscus? Fourth, standard solutions What did you make? Fifth, What is the full form of FAS? And now this one another What is your name? Another name, please. After that, the usual questions Do you understand? How do you feel? How do pipets feel? Again another one Questions are there Why do we add one test tube of H₂SO₄? Why we Add one test tube of H₂SO₄? And the practicals A child for you to kill No handbook will be provided. You have to learn all these things on its own. You have to figure this out yourself. One must go after learning. Here you will find any handbook handbook Not allowed. Handbook not Allowed. Clear, right? Sir, chemistry is over. You said he was the one who came. Look at GameJet's puchro there. All of it right there. It was a bit chilly. Sir, I need the basic radical. He came. Good, he left. Okay, sir. How to solve short experiments and long experiments? Umar, short An experiment and a long experiment are nothing. Short experiment in physics, what is it from? You won't have a graph or circuit diagram to draw. Hoga. I'll meet you and conduct a long experiment. You always have to do everything for me. That's the difference. That's done, I've finished it. About titrations, I'm informed. Now the second one What's coming, Bachchu? Something acidic? It is radical. Acidic radical. How many marks are there? Acidic radical your name 6 What are the marks? How many marks are there? 6 marks. Either with this or I will give you an activity. Activity 4 will be marked. That would be a functional group or a carbohydrate. We'll test the protein and fat. Listen carefully. About you, this Acidic radicals, what all needs to be done in them? Listen carefully. Look here. you who start testing everything like took a mixture and put it in Dilute SCL solution. H2SO4 4 dal. Mixed. Concentrated H2SO4 4 days. This is all you test You're mistaken. Observation. You get 1 mark for this. How many marks are awarded? One mark. Then where are the marks hidden? They are hidden from you. Weight test pe. You, from the weight test 1. You will perform a weight test. Weight test: 1 point. You will get 2 marks there. Weight test, the second one. How many marks will you get here? 2 marks. How much has it become now? 4 marks Sorry, even the weight test didn't give me any marks. I forgot. Potato. Listen carefully. Look. All those things you do, you know. Mixture plus dilute H₂SO₄. Mixture plus concentrated H₂SO₄. You will write an observation here. Here, you will write an inference. You will receive 1 mark for this. After that, listen carefully. After that, this You won't get any result from it. You keep doing CT on him. So, let's do CT 1 on him. You'll get two of them. Whichever one you dilute, test that one. You are going to make CT 2. Then here you will be 2 marks are taken. And here, you are required to How many marks? 2 marks. You got 2, 2, 4, 1, 5, and 1 marks, your result Milt. Please specify the result. It will be CL minus merged. SO₄²⁻ ion. You will need to specify these results. Go there and you will get good marks. Got it? That's it, done. In this, I'll give you the sheet provide hoga. A sheet will be provided. Clear? In this, you'll be given a sheet What will those people do? We will provide. Okay? Does anyone have a doubt about how many marks the activity is worth? What is it for? Activity worth 4 marks is for. And in the activity, you will There is no sheet provided. EMF, if it wants to The RAS factor is all the things that matter to you We will keep giving you tasks. I'm looking into the matter of the activity. First of all, me Basic radical batata ho. Basic radical. Heard it faintly. Basic radical Whenever you start doing all those tests, don't you? Bacha. What does the test mean? The flame test has been completed. The charcoal cavity test has been completed. Charcoal cavity Test completed. Flame test completed. Hitting in a dry test. Dry test. Impact. All this that All this that you do, it's all for you One mark is given. Where do you get the marks? Where do you get your marks? Listen very carefully. You do group analysis, don't you? Group analysis Here you will find It has marks. You need a 2-group analysis. It's Psychic. Either you do 0. Just do one more. Group 1 Zero or one, it doesn't matter. Whatever you have will come to you. It will become 0.2. 0, 3 will come. 3, 4 will come. Any two groups will come. So whichever two groups You get 2 marks there, 2 marks. 2, 2 equals how much? 4 marks. After that, two groups came, two by two. You'll do the CT. You'll take the CT. How many marks is this one worth? It's worth 2 marks. How many marks is it worth? 2 to 2, 2, 4, 2, 6, 2, 8. I did it there at 9. And a result Written. Result. One mark. How much will it be? 10. Here you go. Total 10 marks. How many marks did you get? Total 10 marks. You also understand survival Questions are also asked from the project. Yes, I can ask. How many marks is the activity worth? Activity 4 is for marks. That was your basic radical, after all. In the basic radical, there is no memory of anyone I want to find out through 2-group analysis. 0 if you want, 1 if you want, 1 if you want, 2 if you want, 3 if you want, 4th, 5th, or 1st—anyone at all You should definitely meet with Group A. If the basic radical is present, then 10 marks It happens directly. Now, listen carefully, O donor. Yes, that is the functional group. are you talking about carbohydrates, protein No, these two don't come together, protein Oh, come on. That's just 2 marks. It comes to you, and even this comes to you It comes for 2 marks. Clear? Is everyone understanding? Clear? Okay. Then You can provide any functional group. Can be carboxylic acid. I can't do it. You don't have to write the result bholna. In the result, as carboxylic It's acidic. Please write it here, specify. carboxylic acid Hi, also create its structure. What is the structure of a carboxylic acid? COOH. Write the result like this when They will give you full marks right away. Otherwise, you get this 2-mark functional group. with an acidic radical. Here, we'll cut your marks. Okay? Alright. Now everyone understood these children. If you still have any doubt at all, then Please ask me your doubt here, quickly. Now I'll start the sessions again I am leaving home. Sir, just say my name once my Zypher Okay. Sir Chemical kinetics of concentration of the rate of reaction The reaction between sodium thiosulphate and hydrochloric acid occurs. Alright. Tell me about kinetic as well. The child is asking in the kinetic. sodium thiosulfate N2 S2 With O3, the SCLR that you have What should he do? In that, you need to I want to write. Okay? Observation table I want to write. I need to write an observation table. I want to make a very nice table. After that, write the result. After that, you need to draw a graph. Keep in mind. The tables you You will make it there The examiner is asking: "Tell me the rate of reaction." It is increasing. Why is it increasing? Because What is happening to the concentration of sodium thiosulphate? It is decreasing. Here you will see when you add water. You add water. But at the end, you do not add water. Okay? After that, as you add SCLR I'm here. It takes more time here. But here, time is short. Here, it's even shorter. What happens in the final moments before death? It's a messy situation. Remember those things. Okay? Is everything clear to everyone? Here is your kinetic experiment. Very well for the kinetic experiment I'm giving you the data. Please pay attention. Memorize the table and go. Memorize the aim and go. Go back remembering the conclusion. And go understanding the graph. You learn yourself in the table I don't want to spend time. I want to learn what to focus on. How much? How much in Charu's conical flask? What you need to do. The examiner has asked you to explain. the last one, the conical flask of yours. His color turned dark quickly. Compared to the first one. You want to say, sir. In the last one, we added water. No, what was it? He has more concentration. So his Reaction rate? It's high. And starting now. In the conical flask, we people have What was added to the water? Inside the sodium thiosulfate. That's why What happened to its reaction rate? It slowed down. Because of that What happened to the concentration? It decreased. Clear, right? Everyone? Is the data clear? These kinds of questions are coming up at this time. Enthalpy of? Thermochemistry Listen carefully. This is the last time I'm telling you. Thermochemistry wale ruke Stay. Thermochemistry each The boy is going to the tub. Thermochemistry experiment It's easy. But don't let them do the calculations. No, no. Look, your seat has been provided. It won't remain. You have to write the aim. Observation I want to write a table. I want to write a calculation. I want to write the result. Just go like this, then. Listen carefully. Whoever understands it Copper sulfate by zinc. Copper sulfate or zinc is available. That temperature difference he has, you know Where is it 5 to 6 degrees? I need it. 5 to 6 degrees Copper sulfate in MATLAB I took the temperature. If you're feeling okay, then After 24 hours, give 1 gram of zinc What should your temperature be? 24, 30. 30 should be taken. Lagback 5 to 6 degrees temperature It should rise. Very fast between copper sulfate and zinc The temperature should rise. Only then will you get good marks. Milenge. Doosri cheech. Agar aapko The next one comes in thermochemistry Heat of Neutralization Heat of. This is the second one. Experiment number 8. Heat of Neutralization If you're familiar with the heat of neutralization like SCL or NaOH. To agar isme aapka energy difference like the temperature that comes. If It's okay even if it's a difference of 2 or 3. I mean, like you brought SCL into this I took NaOH. What's its temperature? It has come, 24. It has come, 24. But when both were mixed together, it came out perfect. 26. So, how much difference has there been? It's increased by 2. Matlab a 2-degree rise is being discussed. That's okay. It'll work. But, but if you are Copper sulfate by zinc It's boiling. And at least the temperature Rise by 5 to 6 degrees only Hi, you know what? The examiner will surely deduct marks. You. Your. Okay? Clear? Clear? That's thermochemistry. That calculation. Me. Today I was myself externally. So I was watching. The child in the calculation You're writing so many wrong things. Just fix it properly, Toda. Do the calculation properly. Otherwise, there will be a problem. You're going to do it. Okay? This is your 2 marks. How it works. Let me explain how 6 marks are obtained. For the reading material you take out 3 marks are awarded. 2 marks are for your calculations. It is for you. And 1 mark is for your results. Okay? 1 mark is in your...? The result is what it is. Well then. Sir. Zippe here. Motivate me. What happened? Bro? Zipper. Zipped? What happened to the zipper? Sir, exactly Kid, this is just a full experiment. Pranav. You see, the sonometer. I have done it. Hey kid. You've done this really well. Sir. In Physics. What is this after the formulas? I also need to write the theory. No. There's no need to write a theory, Sir. Today My chemistry practicals have been conducted. Acidic. It came. The functional group came. Really awesome. Veena. Thank you. Why so? Solve the practicals from the last date. Do it for me. Okay? It's not that hard in practice. Your examiner They give themselves good marks. You can see, can't you? So many children are joining as well. If you're not here, then subscribe to the channel, O devotee. Don't even bother knowing. Okay? From the heart It feels good when someone supports every single child. You're hot. Okay? If I were to support you Even you could have shown me a little support. Alright? Come on. OK? Come on. Okay? Then look at more kids, and also at any other child Ask me if you have any doubts. Otherwise, I'm off to the stations. What are you doing? Finish it. Sir, what exactly should I write for the NL constant? NL constant I want to write aim. Okay? Observation table. Write a formula here. After that You need to write an observation table. Okay? After that, you need to draw a graph. Okay? NL constant Pranav. Vaibhav's questions. Sir, physics game practical Do you provide the log table? Yes. Not required. Providing. Tomorrow is my practical. And Vaibhav Please tell me about this. Yes. I'll tell you everything. First, like the videos, come on, like them. Sir, final practicals of biology. Any tips? Life passes by in such a joyful way. Sivangi Bachi. Okay? Good. Really fun. Very enjoyable. Tell me about yourself. My school chemistry teachers say To watch you, Sir Ji. Sir, you are chemistry biophysics How are you? Game Jet. My school The chemistry teacher said to watch. Your Sir Ji. Sir How is your chemistry and biophysics? You don't understand? Bios. Game bios. My school chemistry teacher told To watch you, Sir ji. Chemistry, bio, and. Sir, I have my chemistry practicals tomorrow. I'm feeling scared. Why are you feeling scared? You will win. Sir, I have Your name is going viral in your class. Done. Your next best. You are the YouTuber who banned me. I love you. Thank you, Zip Pe. Zippers. Zippers. Am I pronouncing Right? Zipper. Lovely. Life is. Sir, Zipper isn't studying. Just motivate me. Okay Child. Read and write. The name of the country Do it, Roshan. Okay? My school teachers Tell watch your, Sir ji. Aap chemistry Bio and Kap Se? What the hell is this guy writing? Sir, I've just read it. Yes, 75% will go to you. Ok. To I think mene All the questions of all the children Exactly as it should be, done right here. So can I Close this session now? Sir, I've just studied, and it's 75. Smash games. You can achieve 75 to 80. Just stay motivated. Stay awake for a few hours. Okay? Not now, though. Never. My school teacher Chemistry, tell him to watch your video, Sir ji. Which subject are you studying: chemistry, biology, or physics? Bro, what the hell is this kid writing in the game? I can't understand it at all. You're welcome. You're welcome. Good evening, sir. Good evening. Alright. I am closing the main session. I think I've taken care of all the children. Please provide all the answers.
