Equilibria, Energetics and Elements (F325) - June 2011 Exam.

Mr of Verdigris (without water) = 460.5

You know that 83.7% right? (100% - 16.3%)

460.5 ----- 0.837
x ----------- 1

x = 550.2

550.2 - 460.5 = 89.7

Mr of Water = 18

89.7/18 = 4.98 = 5

Hope this answers your qs

Yep the january paper was very difficult. They ask you to plan an experiment! I wont tell you what 'cos there wont be any point in you doing it

F324 went badddddd.. massive shock. Im re-sitting that. What about you?

Thank you! Wow, I can do like everything else, but got stopped by that relatively simple question.

Thanks! +1

scared about this exam!

I need 129/150 in this module to get A* T____T FML
or 110 for an A

The worst thing of this module is that you gotta remember the colors of complex ions and I can never get my head around them.
(don't want to drop any precious marks).

Revise for the half-term I suppose.

It is a third synoptic, knowledge of F321, F322 and F324 is assumed

If true that sucks since my school switched boards between AS and A2 (OCR Salters to OCR A).

yeah i need 123 or 124 out of 150 to get an A*, and then 86 or 87 (depending on how many UMS marks i get for my practicals) for an A, so quite a big jump haha

my chemistry teacher is like convinced im gonna get an A*
he actually said 'you're guaranteed an A*' haha. i wish...

You pretty much are! 124 for an A* is pretty low tbh, its like a low A!! Can I ask what did you get in F324 and in the practical out of /40?

I haven't started revising for this yet, does anyone know any good sites?

i got 88/90 in F324 in january and 39/40 in my practicals
what about you?

124 for an A* and 86 for an A is pretty standard ha! I got 77/90 and 36/40 so that great

ahhh wicked. you predicted an A then? i did the june 2010 F325 paper this morning, did it with 25 minutes left, got 85/100. not too bad haha
