Just curious. Any particular reaason you take it relative to the vertical?

Really? I know OP1 are given first preference. So is the final cutt-off usually about 96?

Wait maybe he takes his angle relative to the vertical. Bit wierd though...

Um... doesn't horizontally mean the angle is 0? and x(dot) should be vcos0? y(dot) should be vsin0? (when t = 0)

Bout 3-4 weeks time. Late september. Good Luck!

Hehe thanks u 2 Wait actually NO. DONT SAY THAT. You member the last time someone said that! :angry:

Lol ur 4 and a half years late.

Wat do you think you got in the external paper (raw I mean) and just curious, what would an 80+ out of 84 align to?

Ahh k. Makes sense. Just thought it was quite unusual for an ion in equillibrium to generate a relatively acidic solution. Thanks

People were saying in another thread that you should be aiming for a 60+/84 for an E4 (top band). Good Luck.

You do need to have atleast a vague understanding of the preliminary course. For example, 2008 HSC chemistry question 2. No dot point in the HSC syllabus adresses that concept. Although, anyone who paid attention in year 11 will know it...

Ok. Yes makes sense. But I still don't understand. That equation doesn't take into acount: The system is in equilibrium, the reaction does not go to completion The second ionisation of sulfuric acid is essentially weak... Where are all these hydrogen ions coming from?

Yer man. Bout 1.4-1.9pH for a 1M apparently. I've checked multiple sources: macquarie, wikipedia and even notes in class. Can't seem to get a grasp on it. Like you said, its a weak acid... Any ideas?

BAHAHAHAHA omg that wuldve been EPIC!

Well you can't expect a 100 grand salary right after graduating. Life just doesn't come that easy my friend :sun: Do some research but from my experiences, actuarial is the highest your gona get. Your only other option is some sort of investment (although, I wouldn't count on it with a hazy...

DW bout it. If your planning on doing extension 2, your 2 unit wont count. Its all good.

Yer my bad. You don't omit the negative for the final answer.

Yer no worries miss 2010. Dw. Ill be in the same boat =(

Just wondering. Could anyone please explain to me why Sodium hydrogen sulfate is an acidic salt (really acidic in fact). Thats NaHSO_{4}

Then you know what you have to do. Show her that your capable and willing to study hard.
