I'm just curious, for question 12 it says 'electrochemical activity' does that mean that it's from positive to negative, negative to positive, or actually the largest MAGNITUDE to the lowest... i.e. B

So i'm assuming we're talking about it in terms of the products of electrolysis? Well if that's the case because there's only Na+ and Cl- ions in molten NaCl these are the only ions that will be oxidised and reduced 2Cl- -------> Cl2 + 2e- Na+ + e- -----> Na For aqueous NaCl it's split into...

Sorry but Systematic name of vinyl Chloride is chloroethene....

You should be fine then :)

Your Bio and Physics will be the thing that keep you up. Your Bio is looking at a B6, Physics B5, your internal rank for english could pull you down, what rank school do you go to?? I think you'll be cutting it close... I think you'll get it :)

Half a Day + How ever much you wish to spend the night going through.... XD

A raw mark of 70/100 in 2009 alligned to 86 HSC mark so i'm going to say that it would probably be low 80's though i wouldn't be too surprised if it was mid 80's since i actually think this years paper was harder then previous years, due solely to the fact that it was based on skills and...

For POM i'd also include potential of Ethanol and the derived materials of Ethylene, polystyrene and PVC For AE i'd also include Sulfur Dioxide and Nitrogen Oxides...

But i didn't Ruse-Bash.... my posts are gone...

I agree with you, from year seven i've heard about all the Year 12s finishing school and how the HSC is a monster of an exam where you spend all year learning stuff and you only get tested on like a tiny fraction, so you have to memorise whole textbooks etc... I have to say, i've been pretty...

You need B6 or E4 for 10units of your HSC subjects. Also at the start of Yr 11, i was thinking about getting dedicated, putting in the hard yards and trying to ace the HSC. Chances are most of the Yr 10's are thinking like this. What i think is a very good method in Yr 11 is actually...

Last year was the first time they made the MC 20 Qn's. This year there will also be 20 MC, 55 In Longer Response and 25 Options

Yeah i also heard that, but i'm going to stick with it overestimating, just so i'll be a bit surprised :)

Re: Lol people from bos mentioned in smh article Dude who are you?? :P

I understand where you are coming from, but i think most of them would be likely to have a balanced lifestyle. I mean realistically speaking I played about 30 hours a week of soccer prior to this year and probably about 20 hours of swimming. I still go out with mates and things I had a few jobs...

For Chemistry i've been summarising my notes further, i made a summary throughout the year and i've been going through it the past few days and writing down things that i'm not quite down pat on, and well every 10pages i could fit roughly onto 1 A4 page so i ended up with about 20 pages of notes...

Re: Lol people from bos mentioned in smh article You do??? :O

Hahahaha that's probably me :P

Thank you :D

This was what i was thinking around the range of but i thought low 80's, i expect it to be a bit lower this year since it's apparently a harder paper
