    Hey there all,
    Seeing how everyone's setting up a thread for their exam, I though of making a thread for discussing our upcoming chemistry papers. If anyone has some last minute doubts or if you guys want to discuss the paper once we're done, this is the place to do so.

    Im totally doubtful on how the sig figs works with chemistry
    In older papers they loved to not round during parts of calculation questions
    While in the newer papers they do round them, except in some questions like %
    Then you have the odd few questions where they round to one sig fig higher than the lowest...

    Ughh same, I always give it to the least number of sig figs given in a value unless its specifically asked for or if its a mole fraction. But today I was doing w16 23 and for some damn reason the markscheme answers are to 1 sf even tho the lowest value in the question is to 2sf like????

    Also, I'm still not 100% on ir spectroscopy and my teacher isn't very helpful either. Like the examiner report says when quoting absorption wavenumber you're supposed to give one value, not a range, as in C=O at 1750 not 1700-1750 yet my teacher was telling me the exact opposite so I honestly can't trust her answers anymore.

    Hey there! How was it?? Mine was varient 2 wbu?
    I personally though it was overall good but I'm sure the thresholds will be sky high for the paper cuz the questions weren't that challenging. I bet MCQ's are gonna be hard af tho.

    I did 22 not difficult at all, but i messed up the stoichiometry equation. Will i still get marks for the rest of my answers using ecf though?

    Of course, there's always ecf as long as you show your method

    what do we write for melting point decreasing group 2?
    Down the group strength of metallic bond decreases bc nuclear attraction to delocalised electrons decreases. This is due to added electron shells that increase the sheilding effect so less energy needed to break the metallic bonds
