In question no. 5.9 m= no. Of moles therefore m=60/27 ( given mass / molar mass of Al) which is equal to 2.222 now if you substitute this value of m in the equation you will get the answer 1066.7 kJ. Hope it helps
Thank you so much mam , you are the best , you helped me a lot , tomorrow is my test of thermodynamics, And now I am sure that i will score 20/20 marks 😌
I CANT EXPRESS HOW TO SAY THANKYOU FOR YOUR EFFORTS FOR US IN EVERY SUBJECTS YOU DOING FANTASTIC WORK ,,,I AM FOLLOWING YOUR CHANNEL SINCE CLASS 9 .,,,,,,,ONCE AGAIN THANKYOU VERY MUCH ,❤❤😃😊😋
1:10:22 ma'am why would we consider the reaction at equilibrium, can we not consider delta G < 0 as the reaction is spontaneous and solve the inequality?
Mam pls pls pls please start redox reaction chapter fir class 11th ...exam is on 26 sep of chemistry ...please mam .. it's a humble request.. this chapter is coming in exam nd l'm in too muchhhhhh stressss now .. please mam after that ap kuchh bhi kra Dena but redox reaction kra dijiye please...
29:26 you wrote 60 x 24 x 20 = 1066.7 now i think my maths is wrong as according to me it comes out to be 28800 I don't mean it in a derogatory way btw the equation will be 60/27 x 24 x 20=1066.7 i
Please do not say like that..... She has to do many calculations and she cannot do all those manually...So she just looks the last answer. But she properly explains the whe question. And in these many videos being a human she can make little mistakes.. Being a student you should correct the mistake insteax of complaining about her.. At last she is a teacher.
Tumhe itna aata hai na tho aap karke dekhe teaching koi easy baat nhi hai samjhe aap koi bhi kaam karte waqt mistake tho thi hi rahti hai kyou aap se nhi hoti aapke sanskar aise hoge isliye aap aisa bol rahe hai kisi ko bhi kam nhi samjhe sab ke pass talent hota hai aapko galat lagata hai tho aap karke dekhe fir aapko pata chalega fir aapse aisi mistake hogi or log aapko aisa bolege fir aapko pata chalega kaisa feel hota hai Tho respect all the teachers 👍

Thanks I am also co fused in this I try to claculate right ans and I got it but am not sure about it but after watching your ans I am sure
Yes u are absolutely right 👍
Bro where is the equation?
Thanks buddy
I make these 69 likes to 70😅
For 12th question use the simple formula enthalpies of product minus enthalpies of reactant with their coefficients
Thank you so much mam , you are the best , you helped me a lot , tomorrow is my test of thermodynamics, And now I am sure that i will score 20/20 marks 😌
All the best
How much did you score ?

I got 21/25
And now tomorrow is my exam
In q no 5.9 there is lot of mistake if we multiply 60×24×20 we get 288..
But u have thought totally wrong 😠😠😠😑
Ha bhai 🤪
Mam in question 5.8 it's given that NH2CN(g) not (s)but you have taken it solid
ncert m glt de rkkha h question pado isme solid hi h
✨😊So helpful! never mind with little mistakes it's comon! :)🎀👀😇
Mam question no. 6.9 the value of m=60 put kar ne par. Answer rong ho raha hai
Thankyou for good explanation 😊
It is helpful❤

21:15 mein q=-ve hona chahiye because heat is absorbed ""by""" the system??????
In question 5.4 the balance eq is ch4 + 02 = co2 + 2H20
1:10:22 ma'am why would we consider the reaction at equilibrium, can we not consider delta G < 0 as the reaction is spontaneous and solve the inequality?
exactly i did the same
@@lakshmimandal1797 oh okay did you get the same answer by that way?
everyone is not a maths student that was for the biology students

Aap ke answers kese aa rahe h..!! Mere toh nahi aa rahe h..
Cuz wo teacher hai aur tum student😂😂 simple
@@rudranarayansahoo7 ooo thank you bata ne ke liye mujhe toh pata he nahi tha mujhe toh laga ki vo student h..!!
Imagine getting odd number when multiplying 3 even numbers... Q5.9
Maam ques 5.9 mai hum no of moles lena hai aluminium ke instead of given mass of aluminium . 😊
😅 ma'am question no 12 can be done in a more easier way than what you told ❤
didnt ask bro
18:15 Question 5 .5 answer is coming out to be 94.8 ... You are not .. i calculated by calculator... Its 94.8
Thank u mam good explanation by u❤️
Most welcome 😊
Thanks you didi, really appreciate your explanation 👏🏻
Thanks for liking
7:31 mam how to identify when we take water as liquid or when as gas
You've to learn some chem reactions
Why mam in question 9 we don't changed 20 degree Celsius to kelvin because we're have to change it
If you will change it than also the ans will be same as 273+55-(273+35)=20°c
Thankyou mam.... really helpful 👍
Nice explanation mam....!!
Keep glowing keep blowing!
All clear mam thank you ♥️♥️♥️
Welcome 😊
Thank ❤️ you 🥺
Thank you too!
47:14 thala for a reason............
mam on question 5.9 u don't divided the 60g by molar mass
Yess ans wrong h
@@Ambrish-j8mans sahi h bss mam n vo divide krne wali step miss krdi h :)
@@yuyu-f1u hmm.
NH3CN is in gas form
I also thought the same but in question it is given as SOLID.
I think there is some printing mistake in the equation

1:21:49 did any one noticed ? That ma'am was counting ...😂😂
Yes. 💀
Yes
Great explanation!!
Glad it was helpful!
Thank you so much mam,plz make videos for class 12
thank you so much for this video
1:21:53 and goooooo.😂😂🤣🤣

Thanks a lot 😊
Can you pls tell why we have taken -6.03 in q no. 10
Thanks 🙏 mam it's helpful
Mam unit conversation me problem ho Rahi hai Kelvin kabhi mol kJ, Jk inme problem ho Rahi hai
Very 🥰 good explanation all questions thankyou mam
5.8 NH2CN(g) mai hain not solid
I hope it helps you
He new NCERT based in text questions hai naa…. Old ncert m tine questions ni h jitne ishme h.. I’m bit confuse ye lecture Delhi ya old wali m se
Thank you so much
You're most welcome
Ma'am plzz last sum ko v explain krdiya kro ma'am final result lane mei hi tym bht lag jata h..😕
But q2 mai delta q =0 hota hai q nhi
Pls explain?
Q 5.9 me aap ne multiply kese ke bata na maam..?
Que.14 me jo oxygen hame chaiye tha reactants side pe woh to cancel ho gya mam..Yeh que apne wrong karvaya hai😢
Mam chemistry ke vedio upload karo mam please
Thnx mam
Thank you so much mam
Mam l have dout in question 9
24 multiply 60 multiply 20 multiply
Answer 28800 ye aa rha h Last me
Viii to mere ko bii smjh nii aaya💀
Same mera bhi
Direct 60 KJ Al se nhi multiple krna isko al ke moles se multiple krna h
thank you so much mam😘🥰😊😊😊😊😊
Most welcome 😊
Nice
Ques 8 ka nas galat hai -743 aana tha aur ∆ng ki value bhi -0.5 aana tha
Thanku mam❤
Ma'am please try to upload first video of equilibrium today itself in the evening
System of particle and Rotational motion please upload exercise questions mam please mam please please............
In 5.9 you didn't change temp from Celsius to kelvin
Thanks 🔥💯🔥💯🔥💯
Which pen are you using ??
b c b c a d for 123456 respectively
Question 9 me answer ratke likh diya mam 60/27 bhi toh hoga
Tqqq mam
Question no. 5.9 answer right 👍 but method wrong 😢.
maam question 9 wrong hai calculate karne pe uski valu 28800 hai na ki 1066
Divide your final answer by 27 (atomic weight of Al). Also, check the pinned comment.
