i compare to previous years ... really its what you have studied like say the ethylene question that was a bit random. but really if studied and it came up in the test --- bam its easy
i disagree with 10 and 11...im 100% sure 11 is d
question 10 is two seperate equations i remembered doing this in a past paper.
have a look at question 15 in 2005 hsc... same type of question and you will find yourself incorrect.
its c
hahha yeh thats what i said too because it couldnt be an error since they did it several times
and it was obvious as well cause if i remember correctly we dont add buffer in titration...
yeh i honestly thought it was hard. i usually finish most exams with heaps of time but this time i didnt finish 1 question ... was like 3 marks, ohh well
yeh i was thinking about that ... but then i remembered from 'conquering chemistry' optimum temperature and pressure is 400 and 250 atmospheres ... so i thought 350 would be closer to 400 than 550.
dunno could be one of those trick question
i reckon its harder than 2005 ... and especially the first question of shipwrecks threw me off. but yeh did alright, everyone in my class reckon it was and i think so too.
happy its over now my work is done its up to the markers now
dont worry dude, i dont think they started making the chemistry exam after 3 unit. it should have been finished like ayes ago.
transuranic elements are made from reactors by bombarding with neutrons, the nucleus capture the neutron, undergo beta emission and produce new elements. while some...
