Re: CSSA Chemistry 2011 was 3 or 4 marks i think

Re: CSSA Chemistry 2011 I originally tried using the gas constant for it but didnt seem right as i progressed through the questions, then i noticed it had like density 703g/L and 5000 kJ and there was different ones for ethanol so i used those. I got around 6.9km for the ethanol. There was no...

Re: CSSA Chemistry 2011 Similar to what you got, cant remember exactly, i concluded that it was relatively safe because it was below the 650 ppm

Exactly the same for me

I didn't like it - harder then i expected

Re: CSSA Chemistry 2011 i was thinking the same thing

Re: CSSA Chemistry 2011 yeah it asked for the IUPAC name of CO then you had to show via a dot lewis diagram and explain the coordinate covalent bond

Re: CSSA Chemistry 2011 I think so, you had to determine if it was below the 650 ppm, i tried doing calcs but i think i might of stuffed it up

Re: CSSA Chemistry 2011 I agree, the 5 markers i could do, it was all the small 2 marker calculation ones i didn't like

I do, cant say i studied much for it though :/

Pressure: - High pressure favours the forward reaction (N2 + 3H2 <--> 2NH3) - However high pressure is costly so it must be compromised (normally 150-250 atmospheres) Temp: Reaction is exothermic so will shift to reactants to absorb heat While a low temp produces larger quantites of ammonia it...

Irrespective of if their is gases or not their will be no change if the amounts add up on both sides, however pressure is only relevant in gas equations anyways

I find it the other way around :/

I only effectively did half of the prelim course when i moved half way through year 11. The school wasn't to bothered about it. The only way to be sure is to contact a school directly and ask.

I do hsc online aswell :) for bio its great

I moved from Melbourne to Sydney half way through year 11 (last year). In Melbourne i was scoring top marks but after moving to Sydney my marks drastically dropped due to the difference in criteria etc. Also some of the courses overlapped (what was done in vce at the start of the year was...
