Didn't see a thread here for this. How is the revision going for everyone? I'm retaking module 1 and 2. Its going quite good at the moment. Just doing some past papers.
I'm sitting all 3 for the first time on Weds...I'm kinda worried, but I think it'll be alright tbh. And I've got all 3 bio tomorrow...argh. Revision's gone alright .
I'm absolutely terrified. I've done effectively zero revision and I got a U in a mod 3 mock in class I have no understanding with half equations, I'd be seriously happy with a pass. I got a B in mod1 and a C in coursework so I just need to pass which is easier said than done :s ...
argh taking 2 and 3 for first time, got D on the past papers i have done for organic thou... been trying to learn it all but just doesnt sink in... and as a result have odne hardly any biology (exam tues) or maths (S1 on friday) revision
Define enthalpy of combustion. (Another easy one :P)
No looking at notes!
Enthalpy change when one of a mole compound burns completely in oxygen under standard conditions and both reactants and products in their standard states

Define Hess's Law
The enthalpy change of a reaction is independent of the rout taken.
Quite a tricky one: NaX is mixed with conc sulfuric acid and a purple fumes are produced what is observed when AgNO3(aq) is mixed with KX (aq)?
I got module 2 and 3 exams for the first time on Wednesday. Hopefully il be ok but i seriously do not get ionic equations lol. Hope that doesnt come up or im screwed lol

Formation of a yellow precipitaite as purple fumes indicate presence of iodine thus NaX = sodium iodide thus when silver nitrate reacts with potassium iodide formation of a yellow precip
Hey, re-sitting chem 1 and 2 so I put some pressure off module 5 and 6 papers. I'm feeling pretty happy about it at the mo. And to those finding it difficult to remember organic stuff for mod 3, just keep re-writing them over and over again, that's what makes it stick in my head anyway.
