Over 9000, surely. It wasn't that difficult.
You are crazy, it was not hard but it was not easy either. The b6 cutoff should be around that 70-75 mark againit was relatively easier than the previous papers.
the only impossible question was the mercury fish one. others were pretty straighforward.
expect a rise in state averages as it was also the last exam for many people
l'm guesstimating band 6 would be around 80
band 5 would be around 72
dude have you seen the other past papers?You are crazy, it was not hard but it was not easy either. The b6 cutoff should be around that 70-75 mark again
wtf?the MC was pre hard, the fish question was fked, the electrochemical cell (6marks) question was weird, there were lots of dodgy stuff, the atmospher q i only knew the troposphere ans stratosphere where i think there are a couple of more layers, so yeahh, i think itll be 70-75 like any other year.
haha im not saying that you or I got those questioins wrong, im saying out of 9000 people alot of people may have made silly mistakes or didnt know how to do them. a guy from my school left an hour early for example, dont think he gave a shit about the examwtf?
all you had to do was talk about the mercury cell and say it fucks up fish. (FROM THE PREVIOUS QUESTION)
all you had to write down was trophosphere, stratos, mesos, exos. you had to say SO2 was from volcanoes and smelting iron and NOx's were from combustion engines.
other papers asked shit on fertilisers and EDTA acids and shit
l know, but seriously -.-haha im not saying that you or I got those questioins wrong, im saying out of 9000 people alot of people may have made silly mistakes or didnt know how to do them. a guy from my school left an hour early for example, dont think he gave a shit about the exam
yes i did bro.~ trust einstein even though he didnt do chemistryDo you guys reckon it was OK to put CFC's such as CF3Cl for pollutants in the stratosphere?
Eg using Cl* free radicals etc.

it does not pollute the atmosphere. it just destroys the ozone layer.Do you guys reckon it was OK to put CFC's such as CF3Cl for pollutants in the stratosphere?

A pollutant is any chemical in excess that has adverse implications on the environment. I could be wrong, but I think it's okay to use CFCs as an example.it does not pollute the atmosphere. it just destroys the ozone layer.
it's not a pollutant.
"A pollutant is substance or energy introduced into the environment that has undesired effects, or adversely affects the usefulness of a resource."it does not pollute the atmosphere. it just destroys the ozone layer.
it's not a pollutant.
Ok cool beans. Just didn't want to do two in the lower atmosphere, thought I would mix it up a bit. (did SO2 also)yes i did bro.~ trust einstein even though he didnt do chemistry
