6 marker on comparing VRFB's and lithium ion is something my teacher predicted along with defintions of power density i think? And whatever the other one was (i haven't looked at the article in a while). Maybe something to do with oxidation states of vanadium ions and their colours as well

the only organic i want. Except Azo dyes

I reckon they’re gonna chuck in some dna stuff and azo dye stuff as usual. There’s gonna be oz and o mixed into one question and rates of reaction Kc stuff in another question I feel. Then maybe an EL question and a DF one including polymers and involving PL. Then ending off with the DM article

how are we feeling ab paper 2?

Reply 10

Good better than p1 hoping for A* but only need an A

Reply 11

p1 was miles better than that. don't think i totally bombed but still wasn't fantastic. where was entropy and equilibrium topics?? no titration calc either, and a few other topics i expected

Reply 12

Kinda mid tbh, think I did alright but I can never actually tell lol

Reply 13

yeah i think it was good but p1 was better

Messed up most of the fertiliser question doing wrong equations, colours and diagrams ffs 😂 but apart from that decent

Reply 15

Reply 16

I said it forms a green precipitate and the reaction is Fe2+ + 2OH- —> Fe(OH)2 , no clue if its right i was staring at it for a long time ibr 😭😭
