The one from January 2010 seemed to be a lot nicer.

im really happy with the advance notice question because atmosphere has been my best topic in f332. im just worried about the amount of qwc questions there will be in this paper :s

I've been looking at the advance notice, and I had a thought of the topics that they could ask us about:
Composition of gases in the air.
free radicals
photo-dissociation
heavy hydrogen nuclei (my teacher said that topics could also be slightly related to unit 1)
Greenhouse effect

Any others (Although I wanted the advance notice to be on the polymer revolution)

Also, was questions could they ask about on the diagram on the back?

How have you prepared for the advanced notice questions?
I'm really nervous. I've almost give up with chemistry before I've even started, it's such a bad attitude.
I kind of feel ok about the advanced notice paper, but there a few nasty bits in the syllabus I need to get my head around. :'(

We came up with a whole load of questions in class and then our teachers gave us lots that they think will come up as well. Apart from that I'm just clueing up on the atmosphere stuff.
This will be my second time round doing this exam -_-
The maths questions last time really messed me up.

Looking at the pre release material, I can see a lot of E=hv style questions
and gas constant questions etc.

Great. :tongue:
Yeah I don't get how to get revise for the advance notice stuff...
I mean I've read the article a couple of times and will keep re-reading it.
I'm up to scratch with the atmosphere topics.
Especially revised stuff like isotopes, photodisociation, global warming etc.
And I'm going to research a bit in half term
Idk what else :| i'm scared about it, cos our teachers haven't prepared us at al lfor it!
This is a hard paper. If anyone has any questions they're stuck at then feel free to chuck it here
and we can all help you at it.

I'm pretty certain a lot of these sort of questions will come up due to the global warming parts of the pre-release material:

Q) What is the energy supplied to a molecule by infrared radiation of a frequency of 0.5x10^14? Hz
Planck's Constant = 6.63x10^-34 Hz

E = hv
E = 6.63x10^-34 x 0.5x10^14
E = 3.32x10^-20

Easy 2 marks! :smile:

Here's a queston I remember from the 2009 paper I did last year:
Q) Define photochemical dissociation and give an example of it using an equation. <3 marks>

Enjoy. And leave your panicking for the day :yep:
lol only joking ^^
No need to panick if you revise (a bit) ^^

From what I've heard sample questions from the back of the Salters revision guide regularly crop up.

Chemistry will almost certainly be the subject i drop next year, and I'm not too confident about the exam considering our teacher didn't finish the course :/
Exactly only ONE week for the exam now!!

I'm pretty sure gas volume questions will come up, so here's another question example:

What volume of gas is produced when 300g of K2CO3 is reacted with HCl at r.t.p?
K2CO3(s) + 2HCl(aq) -> H2O(l) + CO2(g)

1) Work out the mr of K2CO3
39.1 + 39.1 + 12 + 16 +16 +16 = 138.2
2) Work out the moles of K2CO3
moles = mass/mr so...
300/138.2 = 2.17
3) Work out the amount of gas produced
The equation shows that CO2 is the gas produced, which is at a 1:1 ratio with K2CO3 so...
2.17 x 24 (24 being the magic number you always need for gases)
= 52.10dm3 answer :bigsmile:
