That's what I did. They said to throw in only one equation and I gave like 2/3, is this wrong?


I did the same as you, i assumed it meant atleast one. Im sure they wont mark you down if, and only if all the chemistry is correct. I assume on the markscheme it will have something like CON mark for incorrect chemistry of additional equations. I doubt they can take away marks if the chemistry is correct, im sure they will just ignore it.

However ever, i linked the two equations together so im not sure if this is allowed

Oh wow good luck! I'll be doing that next year haha
Exactly the mark scheme is ridiculous at times >.<


Thank you! And trust me, it makes you want to memorise the mark scheme instead of the actual content :tongue:

All the best for your results :biggrin:

Anhydrous Sodium Sulfate

**** are the grade boundaries based on everyone who took the paper regardless of whether they've done as or a2 chem? surely that would be unfair to the as students as they are probably going to do worse than the a2s?


Yea, I agree. It also depends on how smart the cohort is. If they are smart boundaries go up regardless on how easy/hard the paper is (like in June 2012 :angry:)

I don't think it can be hydrogen bonding as there are only hydrogen bond donors, I could be wrong though :confused:


the OH group could form hydrogen bonds

There was a question like that on a past paper with the answer Anhydrous Sodium Sulfate as a drying agent. So I put that. Awesome. Also what did people get for the other use of CFC one? Gen they said besides refrigerant, I just went F**K but literally at the last second I though of aerosol sprays and threw it down. There was some subconscious logic behind it because Wikipedia implies that I'm right..

Kind of what I end up doing at the end, I put anhydrous sodium sulphate, do I know why? nope. It's just always right :lol:
Thank you! You to :smile:

Yeah but it said intermolecular bonds which means between molecules, I was thinking that at first but pretty sure that's what intermolecular means.

I thought it was the 'propellants in aerosols' and not just the 'aerosols' themselves. I'm not sure if it matters though...
Hi guys, I was okay with everything except the first page :colondollar:, not that it means much, stupid, spawn of satan mark schemes :mad: anybody else really happy about the 6 mark on the advanced notice at the end? The answer was in the article! :biggrin:
I put flame retardants for the other use of CFCs is that right? and what does CFC actually stand for?

What were the large scale uses of chlorine?
I'm pretty sure I dropped about 20 marks just making stupid stupid mistakes. Ugh.

The propellants in aerosols can be CFCs. So that would make CFCs used AS propellants in aerosols. I think. It should be fine..

I wrote disinfectant and for purifying drinking water? or something like that
