definety! read somewhere they give out band 6's for 83-85% + (could be wrong though) so 105/120 so get u there (Y)

=[ lol

my bad nov 2010**

november 2001, got 2.889 years or something 0.889*12 = ~ 10.6ish months that corresponds to november. cause x<=12 think thats right :s...? expecting ~100/120 - got a few stupid things wrong (simpsons rule -_-. put h/2 instead of h/3) was a fairly hard test though

wat was C and D? ie: anyone have the paper so they can tell me lol

yeah my bad but how were we sposed to no the Pb2+ cations had a distinctive colour when i cant find it in and text book :s . only has precipitate tests. or were spose to assume that all metal ions produce a distinctive colour? BOS may take both answers ? :S confused lol spose its only 1...

yeah i did Am-241 and Cobalt - 60. figured i would do both :S. lol

yeah i said something like that. not all the solutions would of given a colour ie: hcl and barium nitrate. people were sayin shit like if would of been toxic with the lead nitrate being vaporised. either way

1)sodium carbonate 2)HCL 3)lead nitrate (i think) 4)barium nitrate (i think) not sure if i put 3 and 4 in the right spot :s . least ill get 1 /2 lol

was such a good 7 marker technitium -99 for medical - diagonistic tracer - ataches to haeglobin etc americium - ... - for industrial use as smoke alarm cobalt -60 - used for measure thickness in metals/ structures ties in wit physics :D

i said industrial chemist (dnt no if thats right)- uses Le chatelliers principle lol - manages out puts /imputs of reactants and products, changes reaction conditions to increase desired product, etc - ie: haber process thats right :s?

wat question was the haber process, i cant remember lol. abit of a blur i fucked the concentration one to, realisted it was diprotic lik 3 mins before the end and didnt hav enough time to change all my answers for the 3 questions. sigh. if u used the 0.005 mol/L concentration for the first...
