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
