    For that question, I swear it said what TYPE of thing is added so I just put an acid..,? Would this be okay?

    I wouldn't think so , but if it was possible , i would've gave half a mark.
    I think you wouldn't gain a mark.
    Its just one mark though.

    I think the question asked what was the catalyst

    Guys can somebody please tell me the truth what I will get?
    I did the empirical formula question and showed all workings out, this was a 4 mark... So I got Pb2O3 which was correct, but I thought because Oxygen has to travel in 2s it couldn't be that, so I wrote Pb2O3 and did an arrow to say Pb4O6 and then wrote that as my final answer but it's wrong! urgh!! How many marks will I get for this? Because I really tried hard for chemistry and I knew how to do that but the stress got over me and I really want to do well :/
    Thank you

    If you mean the x y and z you was meant to write two and I totally misread that so wrote 1. I am beyond annoyed because I memoried all the test for ions so they were easy marks:'(
    What where the ions for the 3 compounds?

    Me too, I thought the 5 mark was horrible on C3, I found out later that no one in my class knew what to say for it either!

    The qustion on the last page about total volume? c3
    55cm^3

    maximum amount of HCl added was 30cm^3 i think... , then add that to the sodium hydroxide (25cm^3) used in the investigation.

    P.S : I hate investigation questions. The reading takes alot of time.
