um, since u kinow the difference between a strong and weak acid, you would know that a weak acid only partially dissociates forming H3O+, ie when weak acids react with water, they are in equilibrium, when strong acids react, they fully ionise (at HSC level chemistry, that is) eg: HCl is a...

they aren't published in any newspapers....

orbital velocity is independant of the amss of the satellite orbiting also, 'r' is the distance between the satellite and earth - u have to ADD the radius of the earth AND the altitude of the satellite, so in your calculations r DOES NOT equal 6.38x10^6m, but rather : r= 6.38x10^6 + 225...

that we received on friday, the 19th december, 2008

i think GENed are like mini courses from other faculties (other than your own)

i had a mate who failed every single one of our tests, including the tirals by 5 marks - so his raw internal mark would have been ~45% but he ended up getting 88 internal and external, so yeh

i edited my post, but yeh as i said, a lot of the asnwers are solid

Okay i'll do 'em now: 1.4.1 (b) okay - from 1.4.1 (a), you get 2.5 x 10^-6 N attraction now the forumula they give you in the formula sheet for HSC is F/l = etc... now they give it in that form for a reason, because that is used to calculate 'force per unit length', ie the force for...

yeh, my techer said even though bromothymol blue changes in mid range, for strong acid-strong base u use either methyl orange or phenolphthalein (the latter ebing better because of the fact that colourless and pink are very distinct from each other) if you look at the titration curve of a...

when do you reckon we get them?

yeh, just a heads up, since it says 'do not bend' (so postmen/women know it's important), some nice postmen/comen (like mine) kindly place it at your doorstep if it doesn't fit in your mailbox without rolling it

Well, i received my HSC credentials in the mail today (as advertised by the Board), but no award for all rounders anyone else in the same situation?

my writing, seriously, was one of the worst out there but i believe in hard work and doing things like everyone else - so i just did teh HSC like everyone else, and got 99.9, beating everyone at my school who indeed had special provisions with extra time, laptops, scribes, etc... sure, it...

short answer is no - not necessarily it could lead to the same scaled mark, and it could not - the two are NOT linked

wrong forum, see the other trhead u started in the chem section!

um, its the first part of the first unit - u should have done that by now (or are you going out of order?) yeh, its making polyethylene ( a plastic) from ethylene, PVC (another plastic) from Chloroethene, etc which i assume a 'plastics chemist' would use...

no he wont he'll be pleased he did it, because now maths will contribute (most likely) 4 units towards his UAI, rather than 3, with 2 units allocation to each of MX1 and MX2 which typically have very high scaling... EDIT: interesting choice Rhanoct as to your uni course - good to see a...

lady from eco and business just rang me to confirm that she can re-offer my schoalrship, cause she's like "we haven't heard back from u, and looking at ur preferences, uve got us 5th on your list" so yeh, i'm pretty sure they do re-offer, but it's a shame it's so late (ie preferences already...

yep, i understand total intake would have to be finalised soon wouldn't it [i would have thought it would already be finalised], cause UAC gives out main round offers in 9 days....

yes...
