AQA GCSE CHEMISTRY UNIT 2 HIGHER CHY2H January 2012 unofficial mark scheme

Was that first part a question?
I'm kidding, but the advantage of the larger surface area is faster transfer of heat, so that would be a relevant answer.

Metaltron, I'm not sure that the gel was metal other than the silver nanoparticles, but I see what you mean.

which question was electronic structure

for 5a) i) Electrons don't carry heat do they? Therefore it would be the fact they're packed closely together (sorry if i'm wrong)
And 5a) ii) should it be a higher surface area?
Good paper I think

what does every one think the grade boundaries are going to be

What do you reckon will happen,
would the examiner not be able to see my answer since I drew the question about the electronic structure in pencil...

I swear I've seen one that gives you full marks.

Hey ho, i'm not complaining I used the textbook method. I was praying empirical formula came up on the exam, my maths skills are impeccable.

Probably 37 for an a*- considering that although many of the questions were straightforward, there was a question on empirical formula. Moreover, many people would have gained poor marks on the first question. Some even missed out the electronic structure question!! 42 maybe for 100 ums.
