This is literally AMAZING! You just saved another student suffering from IB chem. Thank you so much for making this video, and hope you keep continuing with this series. :)

[helenagallardogalan]

THANKYOU SO SO MUCH <3 i have my finals in a week and really needed this 🙏

[bara]

you are a lifesaver! I have been struggling with Stoichiometry so much and I never really understood how to do the calculations but your video helped me to understand thank you for creating it :)

[bdhsh]

That's a great video! Everything is so well explained and I understood it all. However, at 38:43 the video skipped to the ideal gas law section and it did not finish exercises 11 and 12. I am not sure if it is a glitch or if it was done on purpose but I would really like to see the rest of those exercises. Aside from this, I am truly thankful for this video and I love this type of format of revision videos.

thank you so much for just taking the time to explain everything at a good pace and also doing a question section in the video it helped me so much!! i have my finals next year may and i will definitely do good with your videos!

[mayanour]

Oh darling, bless you. Your explanation is really understandable which is rare those days when it comes to chemistry. I have a test tomorrow and was stressed out but I am less stressed out now that I revised the basic fundamentals that I had trouble with. Thanks, dear and please keep doing what you are doing because it is helpful and kind ❤️

[desmonddavidge]

Thank you! please do keep going with this revision series, incredibly helpful! I already know i'm going to be coming back to this video for exam season next year.

[ahlamerfani]

This is amazing! Please make videos for the rest of the syllabus your teaching style is amazing :)

[larissadalrio]

right at 35:30, shouldn't the mass of aluminium be 26.98?

[diyachoksey]

Please make more of this series if you can! You somehow make it all look so easy:)

[beasea]

at 35:28 i think you took Aluminum's molar mass as 22.99, when you should have taken it as 26.98 right? Since 22.99 is sodiums molar mass

[ayushthaker]

pls make videos like this for all chapters - very nice video

[zp_suki]

THANK YOU SO MUCH!! I understood the concepts but struggled during Paper 1 and 2, I now understand what I was doing wrong ❤

[haziqamsyaaar]

this kind of videos do help me to increase my understanding. i hope there are more videos like this. can u do revision for bonding topic ? looking forward for it ! really am!

[franko_henderkin]

Question 11 a is incorrect the Mr of Cu2S is 159.17. You forgot to add another Cu as there are 2.

[dalyaaaaaa]

Hello, this is amazing however, in min 35:20 the molar mass of Al is 26.98 not 22.99

[bharatmadho]

Thank you SOOO much! this is the best revision video ever!

[siyaagrawal]

the mass of Al2(SO4)3 is 342.17 for me and then when i multiply it by 0.2, i get 68.434

[saraamir]

Please do more of these revision videos!!!!

[FarnazHgh]

You are awesome and your expression is very eloquent and understandable please keep making videos.
