What were the 2 boxes that should've been ticked for the equilibrium question?
the rate of the forward reaction is the same as the backward reaction
and
same concentration or something
i dont know if that's right

Loved it! I think the 6 markers were easy to get your head around and although C5 was difficult: detergents, water hardness and fats/oils in C6 made up for it.

I put the forward reaction=the backwards and the concentration is equal I think
Wasn't Poland above the European Union average???

For the moles question in C5, did anyone else get the number of moles as 2.5 X 10^-3 and the mass as 0.25g? I have a feeling that i did the whole question wrong because i got confused at how they gave us two volumes in the question so i didn't know which one to use

Was it like the first question in C5? Do you remember the wording and volumes they gave?
what letter did you all put for the very first question?
I'm hoping for at least a C on that paper as my first exam and course work will defiantly bring it up to a B

Yep I got exactly that (but I didn't put it in standard form) :biggrin:
Anybody remember what they put for the water hardness question? I put-
