    for the first questions on c3 did you have to put symbols or were words fine ??
    It asked for symbols but I think you will still get the marks for the words

    What did people get for the question where you had to balance the equation on c2?
    i put just a 2 on the left side, not sure though. Usually they put dotted lines where you are supposed to balance.

    what do you think the grade boundaries would be for an A in both C2 and C3 ?
    I think it will probably be about 40.. Maybe a bit higher for C2..

    Definitely. I was too baffled to think about that.

    All I wrote was that a disadvantage of adding NaOH was that you had to add it each time you wanted to produce soft water.
    That'll probably score you marks too, thanks, hope you get a good grade!

    for the first question on c3 were they asking for the actual names of the elements of the symbols?
    i think the words but they more often than not allow both, they will allow the symbols cos it was a chem exam, i did words because i think its clearere, it would be mean to disallow either

    I think that it'll be on analysing results from a results table!

    What points did everyone actually make for the 6 marker ? c2
    Direct Proportionality up until 0.7n/dcm3, with an anomalous result in experiment 3.

    With each 0.1 increase the temperature increased by 5degrees

    Maximum ΔT(temperature change) or energy output for the given exothermic reaction had been reached

    For the ions test I wrote like
    Iron (II) ions Sulfate ions
    Instead of Iron (II) Sulfate
    Don't ask why I have no idea.
