so is it 87 or 80?? :/

Ive got a question guys: looking at the chem exam solutions the fermentation of glucose was given as: C6H12O6 (aq) --> 2CH3CH2OH (aq) + 2 CO2 (g)
however i wrote my glucose state as solid looking at the data book as:C6H12O6 (s) --> 2CH3CH2OH (aq) + 2 CO2 (g) would this response be correct.

So my last post until the results come out, what do we think the A+ cut off will be? 103-105 around there? I'm not sure, I look at the paper and think it wasn't too difficult, but I'm worried it'll be higher. haha.

I reckon 103-105 sounds about right. Not too difficult, but a couple of separator questions.

would it be correct to say
Ca2+ (aq) + C2O42- (aq) --> CaC2O4 (s)

and also.. say for a two mark question, if you write the correct answer that would have gotten you both marks but also write an incorrect answer.. do you still get the full marks?

First one is fine
For the second question, no, my teacher said that you'd have to write two correct things to get the marks, otherwise it seems like you are just guessing.

As the glucose is found in organisms it is in an aqueous state, but I have no clue about how strict they will be with marking it.
