    Yeah - in our school were not even allowed to pick between foundation and higher. Ive been entered for foundation english language which is stupendous as i obviously have the learning capacity for higher tier. i will now have to redo english language in year 11 which means i am wasting a year of my learning time...
    Really that not even fair. We get to chose i changed the tier on my chemistry paper in the exam room my teacher did say so many times that if you dont want to do the paper that you have been entered then you can change so i did higher. That's for sciences but i dont know about english. Do you get to do you english GCSE in year 10

    Yeah we do it in year 10 so if people fail they can redo it next year and the school doesn't get a bad record 😂 but I would much rather do the higher in year 10 and then push for the a* if i dont get it next year. I hate the system my school is trying to incorporate...

    I dont think so however insoluable base might be allowed
    Hmm okay. I honestly think the answer they were looking for was just insoluble and thats why they included a table. Im pretty sure you were meant to identify if the metal oxide was in the table or not and since it wasnt you should have inferred it was insoluble.

    But oh well. Just hoping for the best.

    What did everyone write for the equilibrium question as the forward reaction was endothermic!? Does the amount of product produced increase or is it the reactants.
    As the forward reaction is endothermic, increasing he heat will cause it to favour that side, to use up the extra Heat, so there will be a higher % yield.
    So you were right.

    For the question about metal oxide, do you guys think just saying 'insoluble' would just get the mark? The question context was about soluble and insoluble compunds.
    Not sure, I think the answer was Base. It was only a one marker though.

    I put, because the rate at which the heat is being radiated, is equal to the rate at which the heat was being produced by the reaction
    I put because all of the zinc had completely reacted, therefore any extra solution won't react meaning the temperature won't increase any more as the reaction is complete

    I guess they should have worded the question differently as it was kind of ambiguous however I'm sure the answer is base. Same as the carbon-12 question - I had to ask the invigilator for what the were asking for 😂

    Oh no- I thought it was asking about the backwards reaction because this produced the hydrogen iodide (can't remember what it was called) and so the yield of this would decrease because it is exothermic- how many marks would I lose?

    I put that the concentration of the hydrochloride acid and of the the sodium hydroxide is still the same so the rate of reaction is still the same

    No and there probably won't be one soon. I only made the C2 unofficial simply because someone was kind enough to put the paper online so I could write up then answers.

    I think a titration question will most certainly appear on the C3 exam. Aswell as calculating bond energies and probably testing for ions too. Just a guess tho:cool:
    BRO NICE PREDICTIONS! DEFO TRITRATION YEH? Testing for ions is almost always guaranteed and nice prediction of bond energy calcs.

    You are right! It was asking about hydrogen iodide which was the reactant, so yh the yield of that would decrease if temp was raised
