    For the question about how to reduce heat loss, I put add a lid so that less heat is lost to the surroundings. Is that right??

    Also, I think to get an A* you would need 45.

    The atom described in the question about incorrect structure was referring to Neon and I think in the question the electron count was of Flourine??

    Or am I wrong?
    No you are right it was about neon not boron

    Yh thats right
    I think you have to be specific so it would be:

    Aluminium oxide catalyst
    400 to 700 degrees celsius

    First boron (drawing the electronic structure), second was neon (what's wrong).

    From this mark scheme, I got 52 i think. Is that likely to be an A*?

    Also, on the Coursework, I got 40/50. If I get A* on each of C1,2 and 3, how likely am I to get an A* overall?

    Thanks

    No it would be around 52 because last year it was 50 for A*

    What was the third question asking?

    Was it not asking about sub-atomic particles and their charges in just the nucleus so you're not supposed to talk about electrons, right?

    AAAAH. This is insane; judging by the unofficial mark scheme I got around 58/60!

    We had to draw the electronic structure? Damn I could have sworn I checked if I needed to draw anything on the first double page spread. Uh.

    For the question on cracking I put 1. Very hot and 2. Catalyst is this too vague for even 1 mark ?

    I really mucked up today and went into a state of total panic (I have severe anxiety). So annoyed at myself for making silly mistakes because I know that I knew the content and if I'm being honest, though I mucked up, it was a very good paper. If I mark myself harshly what do you think 40 - 45 would get me?

    I put "high temperature" and "presence of a catalyst", not sure how many marks that would get though.

    I'm not entirely sure because some mark schemes say you have to write:

    Aluminium oxides catalyst
    400 to 700 degrees temperature

    But others say that just stating catalyst and high temperature is enough.

    I think you should definitely get at least one mark however.

    That's the catalyst, yes, but I think you just needed to mention the presence of an aluminium oxide catalyst.
    Did you have to state that it needed to be aluminium oxide? I just said "presence of a catalyst and high temperature"
