Edexcel paper 2 chem unofficial mark scheme

They are technically in different hydrogen environments but the difference is insignificant and they overlap so we can consider them to be the same

so you're saying that the answer I put is right...? I know on chemguide it says the same as you've said

Anyone else convert Kpa to P so ended up getting a mass of 21,970 g for the Nitrogen/Ideal Gas Equation question?

No you forgot to times volume by 10 to the minus 3 to get it in m cubed, we all did the kpa to pa conversion

I dont know, depends on the mark scheme, but id imagine youd lose maybe 2 out of 6 for that,provided the rest is right

There was a multiple choice question on 13C NMR where the options were 5,6,7 or 8 peaks. If the benzene are all in the same chemical environment, then that question would have less than 5 peaks as far as I remember. Btw what was your answer for that question?

For test for Br ions was it silver nitrate and nitric acid and cream precipitate formed?

yeah

Apparently there's another one where you dissolve it in hexane and an orange layer forms?

Are you definitely sure about the proton nmr? In the new spec paper 2 there's a question on completing a nmr spectrum and it gives you the benzene hydrogens as a single peak with intensity 5... For for phenylethanal I got 3 peaks 5 to 2 to 1 singlet to doublet to triplet and for phenylethanone I got 5 to 3 singlet to singlet... anyone else?

What did you put for the reason that nitrogen is bigger than oxygen. also isnt that supposed to be paper 1.

ah damn, will that lose me just one mark or the whole thing?

how many marks was the Nitrogen mass question? i got like 0.01g somehow?? whoops

I got around 89 kjmol-1 for the activation energy, would I lose loads of marks 😬
