    Question Chemistry paper thoughts

    How difficult was it in comparison to other papers, also what would band 5 and 6 cut off be?

    Re: Chemistry paper thoughts

    I think in terms of multiple choice was probs same as last year maybe a little more difficult. The core the calculations are harder than last year but nothing like too hard if u know ur content. Questions as a whole for the core were sort of easy but last year people said it was easy and a b6 was still like 80ish raw. In terms of the option for industrial chemistry probs harder than last year

    What'd you get for the equilibrium constant?

    I can't remember the number but the q was a trick solids are not in the equilibrium constant so it was just k = [nh3] [h2s]

    I think it was something x 10^-4 if u use scientific notation

    Nice back titration with the sea shell question. But I got the answer wrong

    Re: Chemistry paper thoughts

    i got something x10^-4 for equilibrium constant too
    if I remember highest cell potential was B.. i remember getting 2.2v for that
    and lol didnt realise sea shell was a back titration but got apparently the right answer of 54.5% or something like that (i realised i calculated percentage weight of sodium carbonate not carbonate, so i did it again in the last 2 minutes)

    Re: Chemistry paper thoughts

    In the cell potential is the question wrong or just a trick question
    Solution says 2+
    But al is 3+

    Did you guys do a linear line of best fit or a curve?

    Re: Chemistry paper thoughts

    Also, is the marking similar to maths where they would read crossed out answers? Seems i got close to one of the calculations but I accidentally crossed it out :<

    Re: Chemistry paper thoughts

    For the graph question, wouldnt it be a curve of best fit
    Considering ladt yrs question on ozone "line graph"

    I remember my teacher saying before that they stop reading crossed out answers in maths now.

    They'll usually mark it if you haven't written anything that contradicts it

    Feelsbad did a good half a pg of working in trials, crossed it out - wrote like less than a sentence that somehow denied its validity. Turns out initial working was perfect ggwp bye 4 marks
