I'm sure most people here did fantastically... but how much reading did they expect us to do?!! I'm praying for some serious moderation!!

It seems I've got most of the actual answers wrong(delta G, I got positive, and pH I got 1.82) but hopefully I'll get the marks for working out stuff.

I think I have lost a good 30 marks. add to that 10 hidden lost marks thats 40. So 60/100 in total. Hope the grade boundary is as follows
A - 62
B - 53
etc etc. coz I gave F325 in jan and thought this one was WAYYY! harder :frown:

I thought delta G was positive was positive?? I remember getting the delta S value negative which meant

Delta G = Delta H - (1000 x - delta S)
= Positive

no??

Thought that was rediculously hard. Worst exam I've ever done. Great, not like a need an A in Chemistry for university or anything. ARGGH :mad:

.

Lets hope the grade boundries are low. FML.

I had 10 minute for last Q. said when sodiumcarbonate is added to nutralise acid. i did HNO3 + NA2CO3 for step 2
but later in step 4 using the same solution they had Copper Iodide :/ don't know where that came from. Thats a gurantee my step 2 is wrong :frown:

agree. some people walked out of my school crying after the chem this afternoon.

Original post by brobro

i thought the biology was a piece of piss compared to this. This chem paper was the hardest ever.

ARE YOU KIDDING ME??!
I would switch grades with F215 from F325 anyday, I need F215 more and I almost certainly did better in this one.

That ecology paper disguised as 'BIOLOGY' was absolutely disgusting and the spawn of the chief examiner in Hell, people at my school started to look at McD jobs and clearing! :s-smilie:

Was I the only one who was actually ok for time? I even had 15 mins left...
Though since everyone is saying they ran out of time it makes me think I've missed something out or did it all wrong :s-smilie:

I chose any acid for the buffer question... I did benzoic acid and got the ratio as 0.23
I swear I got that whole question wrong but I accepted that I would loose a few marks here and there.
I definitely need an A :s-smilie:

I just can't miss my grades, I actually don't know what I'll do if it happens

no??

DG-DH was negative

DG-DH=-TDS

Divide DG-DH by -T and you get a +ve=DS
