31:23 - Good evening. Sorry, but why aren't you taking 2 Hydrogens off (1 from the COOH, and one from Vitamin C) since the hydrogens from the COOH part are not included in y?
I’m not 100% sure what you mean but maybe you have missed that he’s multiplied the no. moles by 10 as he is going from the 25cm3 sample to the 250cm3 sample. He knew the no. moles from the moles of iodine so then you just need to x10
did absoutely horrible doing this paper rn means i have much more work to do
plenty of time dw
3:56 excellent explanation 💖💖
forever grateful to you
in question 6bii, would there not be 4 ester bonds formed? Why do we only remove 7 hydrogens?
love this. pls could you upload paper 3 predictions sir
Paper 3 easier to predict once P1 and P2 are done.

could you please do paper 2 for the same year
For question 6d, why do you not use the dilution factor because it says in 150cm3?

The amount of ads are ridiculous, this must be the best paid fucking chem teacher ever.
Did you make one for paper 2 ?
He doesnt have walkthroughs for p1 and 2,but has gone through some exam questions.
He has a website where he has worked solutions though.
Legend keep it coming James 👊🏻
