    I also didn't wanna write fractional distillation because of this! I can't remember the exact wording but
    I wrote something like heat the mixture to 6 degrees (lol) because that was the boiling point of one of them so this would like evaporate off? Lmfao
    U basically described what reflux is lol. I mean u should get the mark if the examiner isnt being a *****.

    Mr of P is 31 though so the answer in the end should be 0.451/3 metre cubed and many people have got this answer

    Well many of those people are wrong. I've been through this like 5 times now.

    The equation was

    P4 + 5O2 -----> P4O10

    The Mr is 124. (31x4). It's white phsophurus reacting with oxygen. You're wrong.

    The amount of space they gave you to write your answer surely indicated that you must write something more than just fractional distillation, well that's what I thought anyway 😬

    After some thought i'll put reflux in the mark scheme as well. Seems more suitable imo

    I was about to make that mistake until i noticed it was P4 so i multiplied 31 by 4 and got 124. It was a common trick that aqa likes to do and u fell for it and i was close lol.

    1c when it asked how could u separate the 2 compounds

    I think I put something about heating the mixture above 6 degrees (the boiling temp of the compound with the lowest boiling point) and collecting the gas. Put from the answers it looks like I've got that one wrong.

    I spelt fractional distillation stupidly as fractional distilation, reckon i'd get the mark?

    It it mentioned boiling boints..the most obvious one is fractional distillation? Right?

    Would u get it for saying 'heating and evaporating as they evaporate at different points'

    For empirical formula I forgot to do Cu!! So I had a compound of just C H and O. Will i lose all these marks ;(

    I originally did that then realised and added it in! It's hard to say because they usually mark it line by line. If quite a few people have done it though they might allow a couple of the marks. It's not too many don't worry. I've messed up way more than that

    I said to heat the mixture up to 6 degrees. Kinda think fractional distillation was what they were looking for but why give 2 lines for 2 words

    I put that one of the compound has sulphur so you can combust to form so2 - looks completely wrong now lol

    I think if it was an actual chemistry teacher marking them or someone who actually knew what you meant would give you the mark but because the markers of aqa don't specialise in that subject they go strictly by the mark scheme so it's hard to say

    ah so the empirical formula one for me was wrong because I did the other 3 elements and not the 4th one of Cu :/ wow... I got 1:1:4 doe but how did I make that mistake...
    I did that too, i dont even remember seeing cu in the question...
