A+ Cut Off Prediction

[madoscar65]

Definitely harder than last year but easier than 2009

[dopplereffect]

I agree.

Chemistry 2011 Exam 1 - The mutliple choice questions of death

Do you guys reckon they are going to mark the theory questions really harshly? It sounds like most people lost sufficient marks on the MC questions for there to be a large enough "distinguisher" haha.

Yeah, the MC Mass question - I call y'all to duty on it!

Look at the IR in data book, the mass isn't an exact basis - as jane said.

[BoredSatan]

Reckon A+ cut off at around 60/72

the MC was hard and the SA was pretty easy except for a few iffy questions..

[Hamdog17]

I think that it was harder than 2010 and about the same standard as 2009. The cut-off should be about 80-85%.

[nemolala]

guys for the question about caffiene, why cant it be used reliably, what was the answer???

and for part D, what was your answer?

[natalie.krystal7]

It was out of the calibrated/projectable data range provided.

And uh, what d'you mean by D? :S

Would an 83.33% get me an A at all?

Should be fairly safe for an A

im pretty sure the answer was a with the electrone

yeh im pretty sure that the answer is a, the one with electronegativities

look at the data book. its not electronegativity

Nah it's B - though the data booklet contradicts it. All the textbooks are saying it, my teacher said it and even google said it...

[Water]

From Heinemen: For a molecule to absorb infrared radiation, the bending or stretching vibrations must change the overall dipole moment of the molecule.

Dipole Moment of a molecule is determined by teh size of the charge seperation and the distance between its atoms.

Can't find mass from Heinemen though.

*shrugs*


Found it

[Thelimz]

it probably will be around 62-63, considering a 64.5 is 90%

[luken93]

Yeah, unfortunately

But in saying that, I looked at the data book specifically when I reached to question, and since it didn't correlate I went against it Grrrr

[superstar1]

what was the exam out of???
