Since there wasn't an exam discussion for the new spec chemistry unit 2, I've decided to create one. I found it okay, the 1st question I found very hard considering I never revised for gas chromatography. Overall it was quiet easy.

How did you find the paper??????

[tomp33]

Alright, harder than the mock papers etc although that will mean lower grade boundaries hopefully.
I didn't like the how science works q's such as the one about why science alone couldn't answer a question.

Personally, it was quite easy - not that easy. I answered all the questions and had 15 minutes to spare. It was so much easier than Unit 1. What do you think the grade boundaries would be?

Yh, I hated the question about why science alone couldn't answer a question but what did you put for that. Also on the 6 mark question, was it talking about the precipitate? And also on the question about "What information does mass spectrometer give" did you put molecular ion peak?

yeah, ikr. i put the second one.
it was talking about how to form a salt from potassium hydroxide or something like that and it didnt say about precipitate.
yeah i put that too, i put other stuff too, so i can get the mark.

I think the grade boundaries will be quiet high probably 48 A*, 40 A, 32 B, 26 C.

What did you put for the 6 mark question???

Does anyone have the unofficial mark scheme?

hmm, what did you get last time in c1 and what are you hoping for?
err, i put something about how an acid and an alkali make a salt and just went into details, you?

It was 48 for an A* on Unit 1,so why do you say 48 is high.I do this exam next year.

[shibucool]

For the maximum mass question, I put 2.64g. Don't know if that's right.

LOL, I didn't realise that, but the exam was quiet easy so i would think it will be high.

I got 82(A) last time, hoping for at least an high A or A*
Yh, I talked about that, and I also said it forms a precipitate which i think i got wrong in

ooh, i got 82 in biology. got 89 in chemistry ( D: one mark of an a*) so i am aiming for a a* to balance it out.
ooooh. you might be right...
but i think i am happy with my answer.

I PUT THE MOLECULAR ION PEAK! Haha, you have no idea how much that actually means to me - no one else who I spoke to put that. I hope its right :L

On the six mark question, i put about universal indicators and evaporating the remaining solution and stuff. Hope you did well!

[samiraa]

Did anyone else find that harder than the mock?
What did everyone put for the first question why was there a lid on the container ?

i put molecular ion peak too and other random stuff.
yeah on the 6 mark, i talked about that too. ;D

I got this too . it was weird because when I was checking through my exam paper at the end I realised that the relative formula mass for the calcium oxide was 56 not 46! So I had to quickly change it. I got this after so I'm glad I got it right in the end What did you put about the lid on the chromatography paper one? I put that it was so the solvent wouldn't evaporate.

Yeah that was a hard one. :/ I put so the solvent woudn't evaporate - what about you?
