    It doesn't matter what module things are in the unit 5 paper is 25% module 4 and 25% as level chemistry and 50% module 5. paper 6 is ALL synoptic so you have to learn EVERYTHING cry i am going to fail

    yes, the actual module 5 in itself is shorter than the others.

    15% = mod 4
    20% = mod 6 (10% practical + 10% synoptic test)
    15% = mod 5

    nooo not how much the papers are worth mark wise, how much of the module 5 paper will be on module 4 material. its all on aqa website

    why are you ? I am uttely miserable about my chances of success tommorow, i have figured out, based on what i have got for aslevel and mod4, i need to get around 50ums marks tommorow out of the two papers which will total at 90ums marks, so that is just over half right, to get a C overall at A level. its going to be really hard, and that is all presuming i have got the B's in maths and physics which i can't know for certain!

    oh my goodness...

    I cannot do module 5, its like I've been revising for this paper more than any other and I still can't actually answer the questions correctly, or they ask in such a way that I just don't get what they're talking about. Those stupid questions where they have complex A and its blue, then add drop by drop ammonia and it turns green, then excess ammonia and it turns some other colour, then some test with chlorine and you have to work out which TM it is and write equations out and all I can think is WTF?!

    Plus I need to get BBB to get into Bristol, and I'm feeling OK about Biology and Psychology, but I got a C last year, and retook module 2 chemistry in January and got that up to a B, and retook module 3 in june just to make sure, but I have a bad feeling I'm gonna end up with ABC or BBC or something and they won't let me in...

    On the other hand I thought the module 4 paper was really good, though thats possibly because they didn't ask about buffers...

    Oh help...

    (sorry for the overly long post, you don't need to read it all!!)

    ((though posting that message at the end doesn't really help if you read all the way through it before reading that you didn't need to...sigh..))

    just think about all those crappy topics in Mod 1 and 2! Here some of my worst:

    Available chlorine in bleach anyone?
    [basically add dil. H²SO4 and I- ions (e.g. KI) to give iodine, which can be titrated with sodium thiosulphate - 2S²O³ = I2 = ClO- = Cl² ]

    Identifying Halide Ions in solution?
    [add silver nitrate AgNO³ and nitric acid (to stop precipitation of CO³ and other unwanted groups). Chlorides will give a white precipitate of AgCl turning grey in sunlight (UV). Bromides give an off white with AgBr in dil. NH³ but this is soluble in conc. NH³. I- will give off a yellow ppte. and this is not soluble even in conc. NH³

    Reaction of Halide ions with H²SO4?
    KF: KF + H2SO4 --> KHSO4 + HF (no redox)
    KCl: KCl + " --> " + HCl (no redox)
    KBr: Strong steamy HBr funes, Br2 vapour, SO2 also produced.
    KBr + H2SO4 --> KHSO4 + HBr
    2Br- + H2SO4 + 2H+ --> Br2 + SO2 + 2H2O
    Ki: Violent reaction. HI and Iodine fumes. H2SO4 reduced to SO2, yellow S, and "bad eggs" H2S

    Enthalpy of reaction based on ethalpies of formation/combustion?
    DeltaH(reaction) = Hproducts - Hreactants (Reaction, or based on formation)
    DeltaH(reaction) = Hreactants - Hproducts (based on combustion)

    Extraction of metals? Al ore dissolved in cryolite, Ti in Ar atmosphere otherwise the Carbide is formed? Mass spectra? The mecahnisms? Where does it end?!

    yeh I thought it was a good paper although I know I've got some wrong already! what did people get for that question where u had to convert it to gdm-3? and for the Temperature in the entropy one in Section B did you get a really high number?
