re: HSC Chemistry Marathon Archive IUPAC is just chloroethene. Anyway, systematic name means that it's named strictly to the naming conventions. Common name is what it's normally called in everyday talk. IUPAC is what I would call an international organisation that represents chemists around...

Level 4, it's directly above the first year labs. You don't need a login at all.

I think there might be something wrong with your study method. What you should aim to do is a lot of practice questions from a range of trial papers - I would strongly advise against using textbook questions and other crappy worksheet questions. Only exam papers are worth doing. When you do...

Just be careful with your wording, it's not correct to say that back emf is there to satisfy the conservation of energy. It's there because there is a change of flux through the ring which produces the back emf which then means the motor will satisfy the law of conservation of energy.

No one monitors it...so probably limited to how much paper is available which is about the amount a single human can reasonably carry.

Level 4 chemistry - check out the 3rd year study room...also free printing lol

This.

Get your sample and split into smaller samples (a drop is enough). Just add drops for various counter ions and find what precipitates then use the table. Easy.

re: HSC Chemistry Marathon Archive Funny thing is, you can go on virtually any academics website and you'll find they have research partners all over the world...it's characteristic of research, itself.

Underpass between Fisher and Law is good, I sometimes study in my underwear there.

Yeah, multiple attempts in online quizzes usually mean unlimited.

They're all about the same, and MATH1004 is apparently easy but I'm not sure.

USYD Hate Letters is a shit page, in fact, pretty much all the pages have gone real shit.

If anyone here is doing CHEM2XXX and want notes/lab reports and whatnot, pm me. I have full notes for all four courses and lab reports with notes in 2404, 2912, and 2403.

Use Google (Wikipedia).

re: HSC Chemistry Marathon Archive In reality, it's just more scattering of light with HDPE so it looks more opaque.

re: HSC Chemistry Marathon Archive Doesn't really address the issue because density of HDPE and LDPE are almost identical so you'd expect a similar amount of those holes that you talked about.

re: HSC Chemistry Marathon Archive Might be a bit advanced but... Explain why low density polyethylene is more transparent than high density polyethylene.

This, I mean, if you don't show up at any events, you might as well not be in it.

Food, pen(s), water, books and/or laptop.
