    I wrote +3 because it was a salt of Fe+3, the Fe in bold, with the anion containing Fe itself.
    Crap. I saw the question as Fe4[Fe(CN)6] Since the ligand has a charge of -4 I thought 4Fe would have a total charge of +4 therefore that was the oxidation state.

    I don't know. Maybe I was in a hurry to get chemistry over with.

    I remember there was a question about benzene and we had to reduce the ketone group to an alcohol and then add PCl5 to change it to the final product..? Was I correct?

    How did everyone find it? i think it was quite easy, what did u guys get for the enthalpy question? Multiple choice was surprisingly easy! Did any one get 2:5 as the ratio for the Mn042- : S2O32- ?

    Got 1:5 for ratio, by the way it is Mn04^-, NOT 2-
