Great suggestions! =D

Damnit, I'm pretty sure we're doing industrial chem as our option D:

Ok, I probably got this all messed up, but I had a go at it xD \Delta H = nC\Delta T n is the number of moles reacted C is the specific heat capacity T is temerature \Delta H = \frac{1}{8000} \times 4.2 \times (24.1-23.2) \Delta H = \frac{1}{8000} \times 4.2 \times 0.9 \Delta H = 4.725 \times...

Makes you wonder what she did during science in the junior years xD

It's good to use your brain every once in a while =/ What do you think can be taken out without much effort on your part? What comes out when you open the can? We can't be answering every question you have, it's not good for you in the long run xD

I already said the soft drink, in fact, my class is doing that right now, and it's a perfectly viable option. If you really want to to seawater, then just get a container, fill it with water, chuck in an unknown amount of NaCl and some sand/dirt/dead seaweed. Then do the gravimetric analysis...

Uh... the beach where there is seawater? If you do not have a precise electronic balance, I suggest you get one from somewhere. Two decimal places might not be precise enough to get good results, so try get one with as many places as you can.

Seawater composition, soft drink composition etc. You can do almost anything provided you have the right stuff to do precise measurements with.

Of course! We haven't even chosen our option topic yet xD My school loves to screw with the line I have chem on D:

Just salts such as sodium chloride, calcium chloride, potassium chloride etc. and glucose dissolved in water.

Underline the key verbs, know what they are asking, and stick to that if you feel as if you write too much. Personally, I like having one hour+ left over to pad out my answer in case the bare minimum I had before doesn't get me the full marks, or to check over the entire exam. Usually, the...

We're about one or two weeks into genetics right now. [Edit: Sorry for bumping up a relatively old thread, but nobody answered the OP's question xD]

HSC biology student here. We learned about those ions when we did kidney function in Maintaining a Balance. However, we didn't really focus on which ones were positive and which ones were negative. I too, answered with chemistry knowledge xD

I was actually looking forward to module C, and then they dumped this crap on us.

I like everything except for English... And it's the only compulsory one too... T_T
