    OH MY GOSH! IT'S OVER.

    Thats the 3rd time i've taken that exam, for the love of god, I am never doing it again.
    Does anyone have an unofficial mark scheme floating around?

    Plus what did you get on the water of crystallisation question?

    Hope it all went well for youuuu!!!!!!
    x was 16. Are you doing A2?, if so how are you feeling for the F325 OR F324 exam?

    Oh really ? even if they asked us to show outer shell electrons? That's a relief
    oh fudge did they? i dont recall that ! damn 1 mark only out of 2 then
    funny **** with the sarcasm.:L

    The question was testing your understanding that you can have moles of anything (in response to the previous poster before you).


    I think, (from memory), you had something like this:


    Number of moles = m/RMM

    Number of moles = 0.05 moles.

    0.05 x 6.02 x 10^23 = 3.01 x 10^22 molecules.
    you then times it by 5 as there are 4 Cls and 1 Si..... got the PH3 one wrong, where i put Vdw, got the litmus paper things wrong prob.. overall speaking as a A2 student, the paper was comparatively harder than previous papers. Some principles I have a feeling some may find hard to integrate, as F325 (A2 unit) helped out in the calculations.

    Hopefully you did well this time
    The answer to the water of crystallisation was 16 I believe

    yup because its a full shell so no point showing the rest,BOTD(benifit of the doubt woud be given)
    I hope so but what would the other mark been for other than the dative covalent bond between b and n ?

    there was no bonding and structure,many failed to read it was about IE of the LI,C and F

    so its about shells ect
    I'm so happy I read that one twice. I definitely wrote about ionisation energy going up across the period because increasing nuclear charge that increases the spun clear attraction to the outer most electrons, reducing the atomic radius, which increases the over nuclear attraction causing an increase in first ionisation energy:confused::rolleyes:

    yeah the ionisation one you talk about ionisation energy -shells,nuclear charge ,cmon???? why would you talk about structure and bonding :L
    I was referring to the wrong question, which I already pointed out.
    I did converse on the topics that you mentioned so everyone's cool!

    Does the dot formula number show you the number of water molecules in the compound ?

    I did do it.. I just wrote a rubbish answer that made no sense at all
    And it was completely wrong..
    I'm so annoyed cause I really need an A in this :-(

    Anyone got an unofficial mark scheme and what do you reckon the grade boundaries are going to be like??

    It asked for the number of molecules. Not the number of atoms. SiCl4 is the molecule. The number of atoms are (x5) greater than the number of molecules.

    Would I get the mark for concentrated ammonia 'solution' and not just concentrated ammonia?

    For the question about further testing halogens/precipitates do you think putting 'aqueous ammonia solution' would be enough or do you HAVE to put 'concentrated' too?

    I wrote that too but I think we should have mentioned concentrated

    I remember getting 360cm3 for a question. I think you got 360 and multiplied it by 3 but I think you had to multiply by 3 before, not in the end. I hope someone can clarify this.
    I also got 360 cm3
