@13:18 mam in the reaction total oxygen molecules will be 17 ....... So C6H5COOH (s) + 17/2 O2 ----> 7CO2 + 3H2O... So therefore final answer will be=- 28741.3J ~= -28750J
Correct 💯 percent u r the perfect queen of chemistry.....mam.....we love ur subject knowledge....I think I may get more marks in 2021..in chemistry..... because of u mam.....I am big fan of u mam....If I get neet seat because of u mam
What a lecture, i was so happy mam Mam, one thing i want to share with u, that ,most of we are waiting for u to uploading new videos Really u r a 👑 👰👰👰👰👰👰queen of chemistry 🙏🙏🌷🌷
Mam,Can we find del H and del U using the formula del U=Cv delT & del H=Cp delT? If we use that formula then should we take Cp = molar heat capacity at constant pressure and Cv=molar heat capacity at constant volume? Pls reply mam
13:18 mam u changed stoichiometry co efficient of product but u forget to change the co efficient of O2...please check it....tell me it's wrong or coorect me!
mam, in the last question you have done ... at 13:17 when you are changing 6co2 to 7co2 ... the number of oxygens is changing ... therefore answer is changed... actually, the answer is -62500 :) ;)
Hii Mam ....Ge ....Ur explanations will be very clear and with clarity ...Ur excellent madam 😊...my request is u plz explain all the order reactions i.e 1st,2nd,3rd,4th from chemical kinetics ....and can I know one thing mam ...u will teach upto which classes ...I mn intermediate r higher classes also ?? Plz give a reply madam 😊
Mam is this explanation enough for neet xam regard this concept my lecturer has left this concept mam plz do reply mam .Really u r xcellent mam I watch every video of ur tricks aftr learning the concept really u r awsm mam thank you so much...............
quantity of 1.6 g sample of NH4NO3 is decomposed in a bomb calorimeter. The temperature of the calorimeter decrease by 6.0 K. The heat capacity of the calorimeter system is 1.25 kJ/K. The molar heat of decomposition for NH4NO For this answer not coming mam plz help me
I love your videos mam they're of great importance please upload more tricks more concepts you're too good mam 😊 Thanks a ton , will be waiting for more short tricks and concepts 🙏

Yes
2 oxygen atoms come from benzoic acid
it will be 15/2 only
gdmrng ...queen of chemistry

Mam after seeing ur videos..........I can able to answer many questions of chemistry......""""""""fata fatttt""""""""
🥳🥳🥳🥳🥰🥰🥰🥰💕💕💕💕
Ma'am you are really goddess in chemistry please keep helping us.
goddess??
Giving some cheat codes and tricks makes u a goddess??
KOMALI MAM =CHEMISTRY GODDESS FOR ALL THE STUDENTS
Tn q for teaching us mam
What a lecture, i was so happy mam
Mam, one thing i want to share with u, that ,most of we are waiting for u to uploading new videos
Really u r a 👑 👰👰👰👰👰👰queen of chemistry 🙏🙏🌷🌷

Pls reply mam
Mam..aap boht simply hame samjha dete hai♥️♥️apki tricks boht hi powerful hai
#loads of love mam.. keep blessing us
I got correct answer mam.. Thanks a ton .. 💝
13:03 I think the reaction is not balanced as it has 7 C in left but 6 in right......although a very helpful lecture mam....thank you so much
She changed 6 as 7 on right side also at 13:17
Sometimes watching videos like this clear your that one doubt which when cleared completes your concept. 😁
Thank you 😀
Yes
13:18 mam u changed stoichiometry co efficient of product but u forget to change the co efficient of O2...please check it....tell me it's wrong or coorect me!
thank you so much, you taught it so perfectly
You have good explanation mam
Great mam
Ur way of teaching is sooper cool mam....
Mam 7Co2 as you changed then Oxygen Also we should count So Reactant 17/2 for O2
Ya it's 17/2
no it is 15/2 only....bcoz there are 2 oxygen atoms in c6h5cooh
no it is 15/2 only....bcoz there are 2 oxygen atoms in c6h5cooh
Tomorrow I have unit test mam hope this video helps me a lot
Such an useful morning gift😊😊
AN??
Tq mam love u💖
U just cleared this topic in one go with in 5 min...
Do more vedios on thermochemistry mam it is very useful to us
Mam how to know these formulae of organic compounds...(e.g..benzoic acid)here....??
Super trick mam ♥️♥️
Your explanations are so good
Which reference books 📚 are best for neet chemistry class 11 for clearing concepts mam
Mam. Superb class
You made it too easy ma'am thank u
I think in last step temp. Should bhe in Kelvin because of R ( KJ/Kg-k)
I don't know how to thank you mam, you are really great as your videos clear our concepts very well
U are best teacher in the whole world with great simplicity
Please give chemical kinetics shortcuts mam..............
Superb love from tamilnadu in our style veramari mam
Real queeen of chemistry ❤❤
U r amazing madam super your way of teaching, explanation... Everything is excellent...
Thank you 💕
Love you maam seriously
The best
Preparation of study is right
Please translate into urdu during the teaching
According to text book
mam, in the last question you have done ...
at 13:17 when you are changing 6co2 to 7co2 ...
the number of oxygens is changing ... therefore answer is changed...
actually, the answer is -62500 :) ;)
No. Answer is correct. Oxygen is balanced. I think you forgot to calculate oxygen in C6H5COOH.
Komali Mam oh! sorry, mam. A small misunderstanding... hope you forgive me
I also did the same mistake
Hats off 🇮🇳
Gd mng mam. try explain total lesson some imp lessons
Excellent mam😊
Pls upload video daily mam
Thanq soomuch mam👍 good explanation 👍iam new subscription 🤗💐💐💐...
You are the heroin of chemistryy.....im sure that one dau youll be getting some billions of subscribersss....love you mam..ummaaaa
Carry on mam to make videos..
Very helpfull to us.👍tx...
Oooh, just like the calorimetry formula, i.e., Q = ms▲t
God of chemistry
Thanks mam best explanation ❤👍
You are great mam
Thank you so much ma'am.
Hii Mam ....Ge ....Ur explanations will be very clear and with clarity ...Ur excellent madam 😊...my request is u plz explain all the order reactions i.e 1st,2nd,3rd,4th from chemical kinetics ....and can I know one thing mam ...u will teach upto which classes ...I mn intermediate r higher classes also ??

Thank you 💕 & I'm teaching class 11 & 12 ..
Love you mam
Nice video ma'am . Keep it up
Thank you!
Goodmorning mam from Andra
Great!!!🎉
thank you you are an amazing teacher
Mam is this explanation enough for neet xam regard this concept my lecturer has left this concept mam plz do reply mam .Really u r xcellent mam I watch every video of ur tricks aftr learning the concept really u r awsm mam thank you so much...............
Amazing session mam ♥️
Nyc videos...... Thanks a lot mam...........
Mam this is very helpful thank you so much ♥️🥰
excellent explanation
Such a talented mam😁😁👌👌
Nice,video mam marvellous😊
Suprrrrr chemistry QUEEN👍👍👍
Okay man I got it, thank you mam you really teach best
😊👍

For this answer not coming mam plz help me
I love your videos mam they're of great importance please upload more tricks more concepts you're too good mam 😊 Thanks a ton , will be waiting for more short tricks and concepts 🙏
Yeah
Superb
We realy liked trick
Madam I'm requesting please upload video of sterm volmer equation in physical chemistry.
Mam you have said in the enthalpy of combustion ∆n=nr-np but u did np-nr
Mam during balancing the reaction, we don't have to balance benzoic acid?
Are you left hand writer? Thanks a lot very useful madam
does it matter ?
Well explained ... thanks mam
Why do we use 300K/27°C in ∆nRT ?
Fatafat.....
Beautiful Lecture ma'am
thank you mam
Nice video...
I like it, mam tq.🙇
Enthalpy of combustions are in high values how can plastic withstand this much heat , I leaned about copper in insulation
Good video
Please make videos on jee mains fast track revision. Please please
Komali mam best ..... *!!!!!!!!!!!,
Mam the same theme is thought by NV sir
Ma'am there were seven carbons in benzoic acid
Tqqq Mam it's so Easy Now
Nice video 🌱🌱🌱🌱
Mam pls teach the whole chapter wise
What will be the nernst equation for oxygen electrode. Hope u will reply
Thank you mam.This video helped me to solve bomb calorimeter questions easily.
Nice trick mam
Gd mrng mam😃.mam please make a video on wave length and colours of "Coordinate compounds"
Mam can you teach tricks for hess law
Thanks for this great explanation.that's crystal clear..I'm from sri lanka.❤️
Can I ask the title of your video on the part of calculating the change in number of moles? BTW, you explained very well.❤❤
Mam teach on board, it would be so good and interactive.
12:41 there will 7 moles of CO2 formed
Mam condition mentioned nhi hai to hm kaise pta chalega ki rxn constant p pr ho rhi hai ya constant vol
mam problems on heat of neutralisation
plzzz
Thank you so much mam🙏
Thank you 😊
