i really would prefer a piece of paper i can frame that actually has my name on it how is that arrogance?

serriously, id rather a piece of paper i can frame rather than this piece-of-shit medal they gave us

lulz

yeh this Q from MATH132 gave me a bit of trouble as well

Macquarie - best for Actuarial Studies that's all i'll add =)

Okay for washing soda, get rid of the '.10(H20)' ok and you should be able to write a balanced equation now, seeing as it will be a neutralisation reaction, with a carbonate, so products will be salt + water + CO2 ill start you off youll need twice as many CH3COOH's as Na2CO3

SO [H3O+] for 1M will be 0.4% *1 = 0.004 mol/L for 0.1M it will be 1.3% * 0.1 = 0.013*0.1 = 0.0013 difference = 0.004-0.0013 = 0.0027 = 2.7*10^-3 ive never encountered a Q like this in all the past papers ive done, but seems pretty straight forward

yes but we're speaking HSC level, in which case in order to find out whether a salt is acidic/basic you just do those equations

have u searched the forum?

i hear math123 covers stuff like adding fractions, but that's just wat ive heard, dunno if its true

NaNO3 is ionic, ie you cant just say 'Na reacts with this and NO3 reacts witht his' its the ions - ie 'Na+ does not react with water, it solvates, as does NO3-' so in answer to your question, no it produces a neutral salt

yeh that's why in ur definition its nice to put 'the speed at which (blah blah blah) without propulsion (blah blah blah)

at least engrave our names

yep stoopid state government

sure, they delivered them with the post that means u have to sign them to collect them, but the medals themselves and the case are shit, to put it plainly they probably spent more on postage than they did on the actual medals pretty pathetic

IMO UNSW Campus and buildings are better than USYD's BTW i go to neither of these universities

"The term escape velocity can be considered a misnomer because it is actually a speed rather than a velocity, i.e. it specifies how fast the object must move but the direction of movement is irrelevant, unless "downward." In more technical terms, escape velocity is a scalar (and not a vector)."...

why the hell are you guys posting in such an old thread??? BTW COCO_moiselle is long gone - "Last Activity: 7 Dec 2005, 12:58 PM"

i want my medal....dammit lol seriously, it could be another month before we get them!

yeh just rock up imagine if the lecturer had to call out the roll how long that would take .....lol
