In order: Fe(III), Cu(I), Cu(II), Fe(II)

Depends which iron and which copper you are talking about The strongest oxidants (oxidising agents, that is they oxidise other stuff, being reduced themselves) are at the bottom of the table. For example potassium permanganate is a very strong oxidant

Yeah the latter is the way I've generally worked off, so that'll do A table in an exam though?

Anode: Zn + 2OH- ---> ZnO + H2O + 2e- Cathode: HgO + H2O + 2e- ---> Hg + 2OH- Straight from Success One so if its wrong it is not my fault

Jeez they have removed a lot of stuff. Not that I'm really complaining... but they must not think much of our abilities

How would you answer a comparison question? Would you detail all aspects of one cell, then the other with an evaluation at the end. Or would you go through each aspect (chemistry, cost, impact, hippy crap) and compare the cells as you go?

Correct me if I'm wrong but electrolytic cells aren't even in the core topics

OIL RIG: Oxidation Is Loss of electrons and Reduction Is Gain of electrons RED CAT and AN OX: Reduction at cathode and oxidation at anode Never heard of LEO GER: but my guess is that loss electrons oxidation and gain electrons reduction And do HSC papers to know the knd of question they'll...

It is sulfate content. No sulphur

Yeah, that's exactly what I meant

Hahah. Way to answer a question thats already been answered

Excel is garbage. I suggest you go with Xayma's which I plan to do. He seems to know what he is talking about

I agree with you to a certain extent. If you are trying to learn something you have never seen before, you've got no chance, but if you are just learning some aspects of a syllabus point you'll be able to know it.

I know everything about my two batteries, I just don't want to write the wrong equation in the exam

There are a few threads on this, and no. Just remember them, its not that hard. Know your solubility rules and think through it logically

The reduction equation I've got for dry cell is: NH4+ + MnO2 + H2O + e- ---> Mn(OH)3 + NH3 Which is correct?

You'll just have to beg people as quite a few would have done there own major summaries

I have a feeling that is not the reason

Although I think you'll need more than 1 day to study. Just pray you do well in your other subjects

I think there has been more than one
