I made a prediction list of what I think will come in C2 if it'll help!:
-Diamond & Graphite
-Nanoparticles
-Thermosetting & Thermosoftening polymers
-Catalysts
-Electroplating? (not sure about this one :/ )
-Salts
-Empirical Formula (hasn't come up very recently so it's very likely)
-Simple Molecules (Why is Carbon Dioxide a gas at room temperature or something like this)

Most of those didn't come up but IF ONLY I HAD SEEN THIS THREAD EARLIER I COULD'VE REVISED EMPIRICAL FORMULA UGH WE HAVE NEVER BEEN TAUGHT IT AND I WAS LITERALLY CRYING IN THE EXAM IT WENT SO BADLY :frown:

I can add images of the chemistry C2 paper if any of you want to have another look at it :smile:

SOMEONE ANSWER
What was the question on C3 - the last question- asking about the mass? What was the exact question?

so if i wrote an insoluble compound thats wrong? aha i so guessed half of the exam.. there goes my A* :frown:

I put unsolvable compound too!!! Haha probably wrong but at least I was not the only one!

I did too

Either 2 or 3 out of 4 depending on whether they award a mark for stating it is a giant lattice

i said that the negative ions of chlorine are attracted to the positive ions of sodium to form a giant lattice of ions which are held together with intermolecular forces etc

I wouldn't think so , but if it was possible , i would've gave half a mark.
I think you wouldn't gain a mark. :frown:

Its just one mark though.

I think the question asked what was the catalyst

Oh right! Yeah, it's just one mark! Hopefully I won't be like a mark off a grade boundary hahahah

My C2 exam went well, but did not like C3 - it was completely different to last year's paper which my class have done as a mock.

Does that mean you did both of them at the same time

What where the ions for the 3 compounds?

I put sodium for x iron(ii) for y and iron(iii) for z

Anybody got the C3 paper by any chance?

Okay I know this has probably been asked many times now but was the temperature change one 20 degrees or 14?.... As I put 20 because i thought it was a neutralisation reaction (I can't remember if it was or not now) and I thought that the reaction ended once they are neutralised which is at the peak temperature before it dropped? Again, I think I am wrong. Can someone explain why it could be 14? :smile:
