uno wat i mean by titration if u count that wussy lil 1 mark ques as a titration ques, den the cleaner at the local takeaway can call himself an analytical chemist

Net Foreign Liabilities - $290.5bn (42% of GDP) ?!? it thought it was more around 64% of GDP

my skool did q2q sefton whose also selecitve did astro

r u getting paid in cash? or is this a real 'office'?

ah right...ph test i guess u shoulda said u put the indicator in initially before u changed temp or pressure coz u dont really need a one way valve...if there is such a thing to contain gases.. i think i read a comment from last yr's hsc saying "some responses were too fanciful and obviously...

and there wasn't even a bluddy titration question!

office assistant! man wat were u finking?!!? Noodle shop owner is the way to go! wtf do u do as an office assistant? regarding the wage u gotta use enterprise bargaining man! 2 yrs of eco down the drain already and the test isn't even over yet! Tell him that if he under pays you, they u'll...

orangeguy! U betrayed me! i thought we were gonna open a noodle store together in eastward! :mad1:

omg read ur article spice gal "Diane Beaumont, chemistry teacher at Epping Boys High, said students who write well will be at an advantage, while those who do not will struggle." This is her way of pushing the blame from the science department to the english department, when they get...

i already pointed this out in phys thread... anywayz, i fink ppl are juz feeling too happy partly coz most of them have finished their hsc. So they're feeling of relief isn't juz coming from the xam, but also from the fact that they have 3 months to waste in regards to leaving early coz...

the co2<>carbonic acid 1 is pretty ez, but how were u able to analyse the qualitative aspects of it? Coz arent all the measurements quantitative? Like i wanted to do that natural system carbonic acid <> salts from rocks near rivers and lakes equilibrium, but couldn't think of any qualitative...

jeez man, u mustve had really long hair or sumfin

why isn't 14 B? coz temperature increase = speeding up reaction

What equilibrium did u do? I did the N2O4<>2NO2 one, but it took me ages to remember it. All I could recall wen i was browsing thru my book was NO2 on RHS, so i ended up tryn to work out wat was on the LHS. It asked for qualitative analysis, so i spoke about colour changes due to pressure...

dang my memory told me that q8 was water water water. Coz i did sumfin similar to that ques b4. But den i realised after the exam that that ques was only refering to the conical flask. and q12 seemed toooo easy to be D. I put down D, but i kept reading the ques over and over

added to roonie's response, i said that instead of a soft iron core in the rotor, the use of superconductors would induce 0 eddy currents, plus the ceramic material is much lighter and smaller than soft iron, so the rotor is easier to turn. and wiv maglev's, no friction is lost to the rails...

i dunno i put B! my dad juz reckons its C. And ppl at ANSTO and siemens bow down to him dun wanna discuss this ques right now i have chem 2moro

im having some doubts about c, coz i asked my dad and he says max g force isnt max acceleration. He says if the ques is askn for max acceleration, den it's B, but if its max g force, he wreckons it's C. And he's an expert wiv g force coz he drags races at traffic lights all the time jk...

laz, 10c is wrong coz like u said emf = /t The greatest change in phi is when the coil experiences the greatest torque, ie. the initial position. So the graph has to start at its max. Secondly, a one phase ac generate will only have a split ring commutator, so every 360 revolution, the current...

i agree wiv alexz edit: laz, if ur inducing a current, say even in a dc motor, the back emf is greatest with greatest torque. Greatest torque in this case is horizontal, so the greatest induced current is at max.
