Chemistry OCR AS F321 Atoms, Bonds and Groups May 2012

Hey Everyone,
how did you guys find the paper today??? Any unofficial mark schemes going up?

Hey guys,

I found this paper pretty easy, however there were some question were I was wrong. Does anyone know the very last question where they asked what type of reaction was? I wrote its a decomposition however it is thermal decomposition. do you guys know if I will get the mark for just decomposition? thanks!

I thought it was alright but made so many silly mistakes gahhhh also what did everyone put for the acid for sr(oh)2 question? I put H2SO4 but one of my friend was like it's h2so3?

the nh4cl one was so annoying! tricked you into thinking it was covalent bonding by asking about dative bonds!

i put h2so4 as well, but i have a feeling actually it might be h2so3 because i couldn't work out how you would balance it if it was h2so4 which kinda confused me in the paper...ahhhh

Was the answer to the mole 2nd to last question:
95.3
and
Magnesium??????????

pretty sure it was 24.3 and magnesium

I thought the paper was a bit tricky, so scared
what do we think grade boundaries shall be???

Ahh! It was IONIC! i spent like 3 minutes drawing it out and including the dative bonds!
Plus one of the question asked what was the oxidation number of H2N2O3? I put +4... but i got really confused!

And the stupid stupid stupid group 2 metal guessing thing!

But a part from that it wasn't too bad for now, but TSR has a tendency to make me feel worse about myself! So many stupid little mistakes!

you were supposed to subtract the cl2 after u got the answer

what you wrote in the question where they asked why S8 cannot have any other intermolecular forces except van der walls'?
