    I guess my main weakness is in questions not specifically about chemistry theory (such as questions on experiments, data, errors, etc) i'm not always sure what they want as the answer. Topic 1,2,3,4,5 are all fine for me. I may have to revise the core practicals in this section though.

    Can somebody help with this please?

    Which of the following contains the most chloride ions?
    A 10cm3 of 3.30X10^-2 moldm^-3 aluminium chloride solution
    B 20cm3 of 5.00X10^-2 moldm^-3 calcium chloride solution
    C 30cm3 of 3.30X10^-2 moldm^-3 hydrochloric acid
    D 40cm3 of 2.50X10^-2 moldm^-3 sodium chloride solution

    Do you have the paper available to you in even a paper form? If you do, then would we be able to get in contact via whatsapp/kik and for you to send the questions as photos? Would be eternally grateful.
    I haven't got the paper back from my teacher yet as she hasn't marked it and not all our classes have taken the test. If I get it back before Friday I will send you the questions

    work out the moles of each solution first, by doing moles= conc x vol. Then multiply that value by the number of chloride ions in the compound.

    Okay, thank you so much! What's the reason behind multiplying the moles by the number of molecules of chloride ions there are?

    well lets say you have 1 mole of CaCl2 (Calcium chloride). That means there are 6.02 x 10^23 molecules of CaCl2. So therefore to have that many molecules, then you need to have 2 lots of chloride, and 1 lot of calcium. Understand?

    Interesting... I advise you spend more time practicing past papers to get used to the questions, also examiner reports are useful to look at because you will know what the examiner is looking for in your answer to get the full marks. Lastly, avoid marking papers yourself because like me I'm to generous with myself so i let someone else mark it. Do we need to revise the core practicals for the first paper? I thought it was only the second paper?

    I've done all the past papers. I don't know if core practicals are even on any of the papers, I'm just going to revise it to be safe.

    You need the three that are not on organic chemistry
