Sir exams are around the corner. Can you please upload Chemistry videos on a daily basis, they are super helpful! Especially paper 2 as they're not avaiable on KZbin

[@ib3604]

I will be posting N21 HL Paper 2 by tomorrow. And yes, I will try my best to post as many paper 2 solutions as possible before the M22 exams.

@@ib3604 Thankyou so much sir! You have no idea how helpful these Paper 2 HL videos are. There are very few videos available on Paper 2 which has more weightage. Thankyou again!

You're welcome🤞🏻

[@tranganhvo6140]

it seems your answers are very different from the markschemes

[@ib3604]

Can you specify which ones? I will take a look at them at update the corrections.

[@tranganhvo6140]

@@ib3604 i just watched at the start but 1b ii and iii are different, and the IB seems to want the answers rounded to 3 significant figures.

[@ib3604]

I actually went with the data that's been asked in the question. It clearly says 'Find the enthalpy change of reaction in kJ', which basically means we need to find the total Enthalpy change at the end of the reaction(Which is Enthalpy change of reaction*the moles). But i really dont know why in the mark scheme they found out the enthalpy change of the reaction in kJ/mol.

[@gottem125]

In the markscheme it is stated that ignore any steps where the final value is multiplied by the number of moles but you will still be awarded full marks if you do that
