    A2 ECONOMICS: Guess Paper-4

    Hey guys, My friends just noticed some thick black lines on the sides of some topics in the syllabus. Does that mean anything?! Does that mean that questions are going to come from these chapters in the exam?! p.s. The syllabus is attached

    HOW WAS PHYSICS PAPER 5 PPL ? HOW WAS YOUR EXAM ?

    They will give you e.c.f but u might lose more than 2 points for that error :(

    Chemistry 42....how did it go?..expected GT

    I think its actually enthalpy formation of MgCl2 (g) - enthalpy formation of MgCl2 (s)

    A2 Biology | Post your doubts here

    Usually what should we write for reliability in those big 8-10 point questions? Like, calculate for the standard deviation, standard error? Can anyone give me a sample paper which includes this plz?!

    I don't get it, but that question was a goner anyway. gud luck for ur other tests (y)

    Chemistry 42....how did it go?..expected GT

    Ok ok, if u did so much research then it should probably be right. Wasn't E-naught for Chromate +1.33 or something like that? I'm giving the exam from China :p

    t test and CHI-square test 0.05 significance level

    Correct me if I'm wrong, t-test and Chi-squared test, Do they both work with the same mechanism or the opposite mechanism? When our chi-squared value is greater than the value given in the table, the probability becomes less than 0.05, so the difference become significant, not due to...

    alcohol tertiary? are u talking about the NMR question? Yea, I got the same answer for that. Why is Ecell 0.97??

    Chemistry 42....how did it go?..expected GT

    no dude, I remember the question particularly mentioning that the bonds were in the same location. So, I remember that for certain this should be a Stereoisomer, but I just couldn't figure out which type. Finally, I just drew a mirror image :)

    ya I guess I did something similar. But I got a positive value, around 300... :(

    soo cool, nice ;) how did u calculate for the enthalpy change of solution for MgCl2 ?!

    Chemistry 42....how did it go?..expected GT

    I think there could be many possible answers for that question. However, the compound is already a tertiary alcohol, so I doubt whether another tertiary alcohol could be an isomer.

    One more, Suggest why it is not possible to get the enthalpy change of solution for O2- ?!
