    mole calculation question was 0.0045
    Final mass calculation-120kg
    first question- liquids move in random directions-c
    change from solid to liquid is melting
    whats happening in the flask- condensing and evaporating
    later questions about isomers was 1-2 dibromoethane
    the question about organic compound formed when bromine and methane react was bromomethane and the condition was UV light
    this was a substitution reaction
    indium is malleable because it has layers which, with energy can be made to slide over each other
    empirical formula question was CH2F and molecular formula was C2H4F2
    Crude oil question- fraction A was refinary gas F was bitumen
    The structure question was 1-simple molecular 2-giant covalent 3- giant metallic 4-giant ionic (might have order wrong giant metallic has high mp and conducts electricity in both sates)
    Catalyst question worst was the one which didn't make a reaction(possibly d forgot the letters) and the best was F with 11 seconds
    Question about ion responsible for brick red flame est was ca2+. test for chloride ions was a white precipitate and nitric acid is not needed as no other precipitates could form
    addition polymerisation question was R to Q (option c)
    alll i can remember hope i helped
