Not good its going to be nasty. You?

Horrendous

Haven't come across a chemistry paper that convoluted and applied yet. Suggest questions everywhere.

I thought it was quite a weird paper.. Some parts seemed really easy but then other parts I didn't really understand

It defenitely was a hard paper but some bits were okay like the titration, moles and naming colours.... why couldnt they have asked about PET or nylon 6,6 :frown:

That was terrible. Does anyone have any answers for multiple choice? They were really difficult!

Multiple choice was a complete guessing game for me

Did you get 1.27g for the grams of chlorine in the compound?

What were your actual answers though?

1. amino acid, D was 4+5 i think
2. P came last so that was O2+ D was only possible
3. B was peptide cos C was nylon but they both had C=ON-H
4. X3+
something to do with protein structure, said it was peptide and ionic cos i thought hydrogen would be III instead like ZZZ
honestly cannot remember the rest...
+0.49V? 361.92mgdm-3? 5VO2+ + 2H2O + MnO4- ~~~>5VO2+ 2H+ Mn2+?

HAHAHAHAHAHAHA i drew a little monster :mwuaha:

instead of the actual structure cos i have no clue, does it replace?

I just put something down within the last 2 minutes hahah I said no as it would lead to a decrease in entropy which isnt favourable..
