Thanks, think I did that....also on the second page if forgot to half the equations, will that have mucked up every question on that page???
i forgot to half the equations also...but only on the first bit..
i think if you showed the formule (bonds broken - formed) and ( products - reactants) then we should get the mark for that...if we're luck we might even get method marks to show that we knew what to do..

so hopefully you won't have mucked it all up
You know on the second bit of this...about finding delta G...etc, I cant really remember it...did we have to use the equation on this...i cant remember???

i think we had to use the delta S value we calculated and the delta H value they gave us (-46)...

nope we didn't have to use the equation
what answers did you get?
I cant remember my answers at all.... thats whats making me panic!! I always seem to make loads of stupid mistakes on exams, even when I know how to do it.

yup don't we all!
iv made quite a few VERY silly mistakes on the paper...but my methods were all good, and AQA do tend to credit that, as well as not being penalised twice for the same mistake...they carry the error forward and mark it like that..
The waters go above and below a single plane. On the plane, two molecules of C2)4 bond twice (as bidentate), thus the angle between each o-Cu-o is 90o
Like i said I misread the question. I know the bond angles of o-Cu-o would be 90 degrees, I was talking about the bond angles on the ethane dioate ligands themselves.
After reading this I reckon I've done awful, made a few really stupid mistakes like the ionic equations instead of full etc.... and the thing is I knew the ionic

It's easier to remember the stuff you got wrong and not remember the stuff you got right, especially since the people of TSR have a habit of discussing the harder questions. An A in this unit is usually around 70% of the exam. That means it's possible to drop around 30 marks and still do brilliantly. I'm sure you did more than fine
Let it go since there's nothing you can do about it now. Focus on the exams you've got left or if you're lucky enough to have finished them already go and enjoy the sunshine with friends!

I'm going to keep my hopes up then, thank you any idea how much you could drop for an A*? I was under the impression it was 80% for an A and 90 for an A*

Yeah, you are correct in terms of UMS:
90% --> A* 80% --> A
But normally on chem5 it is 70% raw marks for 80% ums.
