Na that was the question after that

yea but you had to say why NH3 had a greater boiling point than PH3. Now surely one mark is for saying Hydrogen bonds are stronger than Perm-perm...or perhaps because of EFC, you'll get full mark?

anybody got the paper? It'll be amazing if you could post it.

guys,
for the confirmation of I- the other test after agno3

i put concentrated and dilute nh3
??
i forgot to put aqueous. does this matter and did i contradict myself by saying dilute and conc??
i made sure to put concentrated first as ocr are funny and will only mark first suggestion

i mean, usually we do add dilute drops and then a bit more, surely i can still get it?

You shouldn't get it as it is only conc ammonia solution that is used for bromide ions.

I thought it was okay, made silly mistakes here in and there, I'll probably end up with b if not a c.

Even though the exam went great, I learnt my lesson to not leave revision to the last minute after that horrendous biology exam. Going to start revising today.
