    They do. Mostly its same 2000's cuz 90's are repeated in 2000's to if you see the 90's paper you will see so many repeats.
    do you have a site where you get the 90s papers?

    I know i found papers for physics too thats not the problem. The problem is finiding the answers. I never find marking schemes for them.

    Anyone here gave the v32 practical paper today?
    yes i did and dont even ask about it !!!1
    it was a hectic
    1) it was too long
    2) where did they get questions of cations and anions from i mean like srsly whats wrong wid u guys ?!!!!!
    3) the inverted thingy what was wrong with it ...i mean for me the whole thingy got empty
    i mean measuring cylinder
    and plus i read the measuring cylinder in the wrong direction
    and i left like a few questions as in the first question calculation and the estimated error plus the identifying the FB6 cation and anion
    although i had an idea it was nitrate but im so dumb i dint write it down ?!!!!!!! omg i feel like killing myself

    So-so. Some parts were better than others. I really struggled with identification.

    One possible way of going about this question is Hess' Cycle.
    If we use the equation for the enthalpy change of combustion of S8
    S8 + 8O2 --(-2376)---> 8SO2
    If we take enthalpy change of S=O bond as x....we could form an equation in x and solve it. Name:  so2.png

    it is the way Ink red did but the calculation is wrong.
    write the equation s8+8o2------> 8so2 and draw the Hess cycle with S8 to 8S just like how Ink red did.
    then the calculation part is
    2232+[4*496]+16x=-2376
    -2376-[6200]=16x
    x=536


    hope you get it.

    I messed up the calculations of both the questions. The question based on qualitative analysis went surprisingly well. Also, what was your titration reading?
