Good luck all. Let's hope the screwed up Al(OH)4 question doesn't come up and that AQA fix it soon.

i hope the paper isn't too bad, fuel cells are a bit of a bitch and i quite like the complex ions to be simple ones with just nh3, oh- and co32- none of the aerial oxidation ones of ones with peroxide

question guys! if you are calculating entropy say N2 = 192.2 do we divide by 2 coz ive seen that in jan 2011 MS Q2e

Yh because in the equation, we have 0.5N2, thefore we divide it by two. So th entropy values are proportional to the moles of each molecule.
