    I wrote Anhydrous Potassium Sulphate....Is that acceptable? Knew i should of put Sodium -_-'
    Markscheme will be along the lines of

    Anhydrous (sodium sulphate) - ALLOW Potassium/other named G1 metal

    The anhydrous bit is key

    Don't think so, because that implies that its NO2

    Lol, i don't think our exam officer is that cool with handing out papers- he seems moody, but if you dont mind can you please upload a copy of the one you were given?
    Edit: I just inspected it more closely, she actually just gave me a load of the spare advanced notice articles all piled together wow, this is embarrassing, sorry to get your hopes up she likes to play pranks on students .

    i finished the paper in an hour an 10 minutes and spend the other 15 minutes doing the last question. I agree it does seem at the same level as the june 2012 but i hope i done better than my low B

    What did you write on the last question.
    For the release of N2O, I wrote about nitrates being converted to N2O, N2O gas being given out from the oceans as it was not very soluble
    and then for the removal, i wrote of photoylsis of n20 and gave few equations, then i wrote about nitric acid, reaction with oh radicals, wet deposition and then about PAN though i never actually ever understood the idea

    Ye my answer was surprisingly simular, although it was a very open Q especially because you could only write and explain one Eqn and yh i also mentioned the OH + N20 in the removal as a propagation reaction as NO2 is a radical, not sure if it will be a marking point, but thought i'd chuck it in there..

    i think it might be a marking point, it does make sense and yes it was an open question. I just hope it turns out all alright in the end otherwise uni will miss me.
