    Differentiate alkene from alcohol: Br2 in CCl4... Your other answers seem right, just the osmotic pressure question, I doubt the osmotic pressure would have decreased. Oh well, i wrote increase and structural isomers.

    Q10, the hess law question, I said C, which was enthalpy of atomisation of carbon and hydrogen and enthalpy of formation of methane... I tried it too, it works, so Im guessing its the right answer. :)

    For the osmotic pressure question, I chose: increase in osmotic pressure and structural isomers. For the old lime to new lime question, new lime was CaCO3(s), so the equation was: Ca(OH)2 + CO2 = CaCO3 + H2O Question 40 was A, all of the listed compounds had the same C:H ratio: aldehydes...

    A is right for question 2. It was 5O2. For the question about the non metallic element in fuels, that oxidises and stuff, the element was nitrogen, and I wrote D too. :) For question 39, I wrote C, that is CH3COOCH3 and CH3CN.
