do you know what jobs I could go into with a chemistry degree?:P

If a ionic lattice has more covalent character does it mean it will be more exothermic?

The question makes no sense. What will be more exothermic ?

Will a mixture of ethanol and water become more or less dense over time (assuming the mixture is open so air can get to it)?

I have a question about the property of acids. All kinds of chemical compounds which donate protons are called acids. And then the protons were donated in a chemical reaction, it remain a surplus of electrons. Is an acid a chemical substance which consists of negative charge?

No. The acid is the molecule which donates the H+. The species remaning after (which has a charge 1 lower than the initial acid) is called the conjugate base.

For dibasic acids, such as sulfuric acid, the HSO₄^- intermediate is both an acid and a conjugate base.

I see. Whenever an acid donates protons, a conjugate base as reaction product come into being. The other way round a conjugate acid as reaction product come into being whenever a base accepts protons. Am I right?

I see. Whenever an acid donates protons, a conjugate base as reaction product come into being. The other way round a conjugate acid as reaction product come into being whenever a base accepts protons. Am I right?

but is this characteristic the only one? are acids and bases just define as proton donator and proton acceptor?

Hey, I was just wondering if I could ask a question about revision. I know this seems quite stupid to ask - but I am finding that revising for university exams (I am studying Chemistry in my first year at Warwick), is so much harder to revise than for A -Levels, GCSEs, etc, which is definitely expected. I was just wondering how you guys, if you are at university, have adapted your revision for your undergrad degree, and if you just generally have any other revision tips?
Thanks!

You know you have a Warwick chemist right here you could ask . (Long time, no speak on that note).

In terms of the exams you have:

Organic: You need to know pretty much everything you've been taught. You will need to know everything you've been taught in term 1 and 2, polymers and introduction to biology is a bit hit and miss. Luckily, you have a choice of questions, so it was glorious when they lumped the biochem and polymers into the same one, so everyone skipped that. Note, they will NOT be doing that again, so make sure you know one of them

Inorganic: Deeth's stuff . This will come up. Ruorke's stuff on packing, not so much. You will need to know trends and all the other polava that you learnt.

Physical: Only do the questions sets. You won't need to know any of the theory.

As for learning styles, I tend to write out all of the lecture notes (each set in turn), move on to a different module, the come back to the previous module and do a written and computer summary of no more than 5 pages. Then, when you visit it again, just look at the summary and write out any expansions on that summary that you can think of!

Everyone's different however. For physical, a group of us got together and gave each other questions on the white board to do - in my opinion, that's the most difficult exam to revise for. The others is just remembering rules and trends
