why is the paper white? mine was brown.......i think :|

Geez, although i thought the exam was harder than previous hsc, it was still fairly easy. I guess we'll find out Dec 18th or whenever

Yeah, this was pressed so hard by my teachers in yr11, in chemistry, only moles can be compared, not mass

Oh yeah, Mr. I ace'd the multichoice sitting right here :P

14, it says in order of INCREASING oxidation of metals... so i put D, im still iffy about it but im becoming more confident 15. simply look to the left, you should have known either carbon rod = cathode, or zinc case = anode, and from there you should know anode = negative terminal for...

I've never gotten over 90 raw in anything, but fingers crosses for band 6 :D

anyone who gives you a answer to this is just pulling it from their arse, no one knows how much the aligning will work, it depends on how well your school went, and how well the state went

Barium ions in a alkaline solution :P i think its yellow with Silver but i wasnt sure

LOL, the fact that there was more NO than O3, suggested that O3 was a limiting factor, and hence, A

I put reduction of water and oxidation of Br-. I reckon, of all of them he was my worst one :P, i blame the macquarie book they didnt go in enough detail :P

They ADD 90mL to the already present 10ml, so V2 = 100

Your right about ozone being the limiting factor, but you prolly used the wrong mole of gas volume.

not much BS from me, and i still wrote 2 pages :P basically, it said 'increasing knowledge' i so talked about the evolution of ships, first, 17th cent lead sheeting and metal was only for fittings etc, then copper, too expensive, then brass( or bronze :S) , fittings needed to be caulked, then...

??? its the hsc, they dont make mistakes :P electrolytic is covers both electrolysis and galvanic reactions

well, you cant exactly have a combustion that sucks up energy :P

ahem, electrolytic != to electrolysis :P took my a couple of seconds, but the diagram shows no power source is a extra clue

hmm, i never knew it was a 3 step process, i always just wrote free radical reacts with a ethene molecule, forming a activated monomer. then the activated monomer reacts with another monomer forming a dimer, this process continues untill the the chain is stopped by a free radical joining the...
