    Do u guys think the real papers will be as hard as the specimen papers because if they are then i have flopped it
    I doubt it but just expect them to be as hard so you'll be more prepared.

    I asked my teacher and he said that he really didn't know. The real papers may be as hard as this. Chemistry was my favourite subject and it's just taken a toll on me now :afraid:

    If anyone is free to help, could they possibly help me with the last question from the specimen, paper 1.

    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

    A calcium ion is Ca2+ and nitrate ions is NO3- so you need two nitrate ions to balance the calcium ion

    I actually thought the specimen papers weren't too bad (out of 2 specimen papers and 2 Teachers' only specimen materials only one of the Teachers' specimen materials was actually hard) the specimen papers were okay

    I'm not sure if my method was correct but I remember getting the answer correct:
    You would find the moles of each thing. But for Aluminium chloride you'd have to multiply your answer by 3 because it's AlCl3, and for Calcium chloride you'd have to multiply by 2 as it is CaCl2.
    (That was a lot of work for a multiple choice question though :/)

    Is this the specimen paper that's not available online? Because if it's that one then I found it very difficult!! I especially didn't like the long answer questions. The second specimen was slightly better than the first but overall it was not a nice and I will pray hard that our actual paper isn't like that haha

    Is anyone free to give a quick reminder of which types of reactions we need to know?
    For example, metal + base/ acid reactions
    We learnt them during GCSEs but I've completely forgotten them now

    What do we actually need to know for 'relevant practical skills'

    I know we need to know how to carry out the practicals but that's about it

    If there's a question asking us to write an equation for the standard enthalpy of formation of a phosphorous containing compound, would you write phosphorous as P or P4? Similarly with sulfur - would you write S or S8?

    The mark scheme accepts both whenever I see those elements

    Do you think the specimens will be as hard as the real ones, If so I think grade boundaries may be lower than previous years

    Won't put my money on that. They will probably slightly lower them but not significantly. It all depends if they decide to lower the proportion of A grades, in which case they won't go down by as much. If they give in to the pressure by the government to lower A grades, then those people who are at the low A side with the old spec will be affected the most
