yes and yes :wave: I have emailed you!

Subjects: Preliminary and HSC Chemistry, Physics and Mathematics (2U, 3U, 4U). We can also assist you with qualifying for the Australian Chemistry Olympiad Team. George can also help with chemistry, biochemistry, physics or mathematics at any university undergraduate level. Format: We offer...

your understanding is correct, just that "explosiveness" has nothing to do with redox potentials

BTW, i still need a definite answer on the Fehling reagent ANYONE? :(

I think there's some problem with your formula of fulminating silver. Entropy wise, your thing "can" explode but not THAT preferred. Maybe since thermodynamically, Ag wants to go elemental and grabs e- from N3 giving N2 and water or maybe a lil H2? But a lotta bonds must be broken to do this so...

err? how is TNT a strong oxidising agent? Correct me if I am wrong but I think this rxn is entropy favoured and happens fast partly due to the emission of gas ... and by your analogy, i am the possessor of ~ 100 grams of potassium dichromate, why haven't they exploded? sorry if it seems...

and why is ammonical silver explosive?

merc can u gimme site where u found all this? cheers

ruka i wanna awp u again before i go china :) get chop

me take all three of u on @ spacie :)

Lime water reacts with atmospheric CO2 Fehling reagent is copper 2+ ions in sodium potassium tartarate and sodium hydroxide. Maybe CuCO3 formation/ppte? Anyway I cannot find the answer online :( do any of you out there know?

Does anyone know why Fehling's reagent must be made only just before it is needed? I cant find the answer online :( Thanks heaps!!

omg opal, 94 for phys (thought u got 96+).... i feel ur pain :(

Lol hard to say, no one was real serious

Australian unis are all stuffed up. The UAI cut-offs are all screwed! How can medicine cut off be higher than biochemistry and nanotechnology? Consider this, a doctor earns cash provided other people get sick, how stupid is this? Our non renewable sources of energy, crude oil / petroleum...

rukawasan, how can X be interested in forensics without having a liking in science subjects like chemistry? if she really likes forensics maybe do sci/art or smth (which is really flex so she can do jap) then do forensic in like 2nd yr

A basic example Calculate the pH of 0.1 molar acetic acid (pKa = 4.76)
