Hey, they could just go full retard and make it 38/60 A* like with C1 june 2012 :P
ahahahahaha ideally yes!!!! I feel like this will be a low boundary! Maybe not that low though..... I personally reckon it'll be like 46ish for an A* then down in 8/10s for each lower grade, but there's nothing we can do about it so I reckon we should all just leave it lol

I think I did pretty well (although some of you A* students don't want to hear that due to the grade boundaries!)
The only questions I personally got wrong were:
-The emperical formula (although it was very easy) - which would lose me around 2 marks out of 4
-I also didn't mention exothermic. Instead, I stated that more energy will be needed to get rid of the water - which is completely wrong. Does anyone know how many marks it was?
-Also, what did people get for the equations? For one of them, I got CuO + H2SO4 -> H2O + CuSO4 and for the neutalization one, I got Sodium Hydroxide + Hydrochloric Acid (I think) -? Sodium Chloride + Water
-And, for the mean, did you have to exclude the anomaly? How many marks was this question?

What other questions were difficult?

Oh, and one other question! What did everyone get for the iodine one? The question where you had to state the amount of electrons it has in its full outer shell; I wrote 7!!!

Did you have to put state symbols?
I dont think so; i think the main bit is the charges and the H+ and OH- ions and the water at the end.

the equation one you got right...the neutralisation one was H+ + OH-=H20 so you got that wrong. I made so many silly mistakes. and the outer shell was 7

Hey Amy! Is your question regarding the neutraliziation reaction?

But wasn't the neutalization reaction regarding the substances they gave us? Because they gave us a base and an acid.

hydrogen was in there.. i think i made the same mistake as you i wrote NA+ + OH- = NaOh but im not to sure

Wan't it supposed to be simple? Sodium Hydroxide + Hydrochloric Acid -> Sodium Chloride + Water

Do you know the exact question?

What was the HARDEST question on the paper?

CAN SOMEONE (WHO DOESN'T HAVE P2 TOMMOROW) MAKE AN UNOFFICIAL MARK SCHEME? I MADE ONE FOR P1 BUT I HAVE P2 TOMMOROW!!!

Haha, I think we're both talking about the question which had the word "neutralization", aren't we?

Anyone doing physics tommorow?
I am! I find the forces and energy section quite simple but it's the nuclear radiation and life cycle stuff that I think I'll struggle on.

well everyone in my school wrote H+and OH- to give h20 which is neutral..

For the ionic neutralisation i wrote H+ (aq) + OH- (aq) ´------> H2O (l)
Did you have to put the state?

No I don't think you do! I'm pretty sure they were just looking for the ions!

That's lucky. I am the only one to find the paper really difficult looking back? Low boundaries maybe?
