    Was it not SF4 to SF6? Did I misread the question?
    I put 6SF4 + 02 --> 4SF6 + 2SO

    Yeah it was SF4 to SF6. The question said blah blah "the reaction of sulphur tetrafluoride with oxygen to form sulphur hexafluoride"

    I put

    3SF4 + O2 ---> 2SF6 + SO2

    I reckon they'll allow both? They both balance and make sense.

    3SF4 + O2 ---> 2SF6 + SO2 is correct I think. I doubt that SO would form.

    I had a quick count and managed to drop at least 25, just through pure lack of knowledge and the others not being as detailed as they should have been. Not good!

    I have an English Lit exam tomorrow morning. I need to get off TSR.
    but its so addictive (comming on tsr to see what people got in their answers) lol

    It said the oxidation state of chlorine was +7 so I thought chlorate would be ClO4- making KClO4 but google says KClO3 is potassium chlorate and KClO4 is potassium perchlorate so who knows

    Edit: apparently KClO4 is also called Potassium chlorate(VII) which would make it work.

    Yeeeeeeeeeeeeeeeeeeeeey!!
    For that question instead of drawing out the whole molecule i thought id draw just the COO-( so basically, just the carboxylate anion and of course the the other molecule i got right with was protonated nitrogen..

    Helppp :/

    I thought it was alright compared to the biology paper!

    did people write electrophilic substitution for the first question about the type of reaction?

    Has anyone found an unofficial mark scheme yet?
