    Thank you, I stress a lot over each answer you see x
    Periods go across, groups go down.

    Also what about the first six marker? About the solubility of diamond and sodium chloride.

    How many marks out of 6 could doing this get you?
    probably 2-3, because the question did state describe the experiment first then use it to explain the empirical formula

    What did you guys tick for the question that asked for the formula for Na and SO4?

    Overall in my opinion the chemistry exam was fairly easy, the question I would say i struggled with was the last 6 mark I worked out the empirical formula of magnesium and oxygen( by subtracted magnesium oxide by the magnesium) and i got MgO, which i think would award me 3 marks then for the experiment part i wrote a line about heating the magnesium which should hopefully get me 1 mark, so 4 overall i think on that last 6 marker.

    It was 35%
    Working out:
    2×14=28
    28÷80=0.35×100=35%

    But was the formula in the question what I stated it was? (NH4NO3)

    Oh okay thank you! When I answered that question I worked out the empirical formula first because I didn't know the experiment but eventually I remembered it and put it after the working out for the formula. Could that still give me marks even tho it's not in the correct order?

    No groups go across because alkali metals are group 1 and halogens are group 7 and they're on the right (lol that's how i remember it at least)
    So group 1 is the first column and it goes down?

As p1 was hard in core science,I still managed to get an A*. Good stuff. Good luck in your exams a and hope everyone Be the very best and say 'Gotta get A*s in 'em all'

    What was the question everyone got 35% as the answer? I got 30% because i must have misread it, also what was the question to do with finding 'how many tonnes can fill 500 tonnes' something like that.
    The percentage of nitrogen or something

    Until now, I'm losing maybe 3 marks on the last 6 marker..hopefully
    + 2 marks on that reactant question ('cuz I'm an idiot and messed up the breaking/making bonds bit)
    + 1 mark on that barium sulfate (forgot to use the word INSOLUBLE- thanks brain!)
    + 1 mark on that balancing equations thing
    + the rest I don't really wanna think about it.

    I'm just hoping that grade boundaries will be 51/52 for an A*..dear Lord, PLEASE.
