Those who got into medicine: You did UMAT and passed the test and interview?

Hmm, I don't think he cares anymore. This post is quite old, I'd imagine he's finished the HSC!

Ahh I get it. Thanks both of you!

Erm...no, you've lost me on those 3 lines...

Show that 12^n > 7^n + 5^n where n >= 2

We're only required to know one other besides cellulose. So you can't add anything?

Hmm, okay, regarding PHB, does this answer the dot point "Assess the current development in the use of biopolymers"?: PHB (polyhydroxybutranoate) is a biopolymer originally produced by the microorganisms known as "Alcaligenes Eutrophus". In the past few years, scientists have successfully...

For his second question, you haven't answered it, but merely restated what happens. The question is why light can't escape black holes yet X-rays can. This seems contradictory because both are EM radiation. And what's your point in mentioning that x-rays have higher frequencies?

I get ya, thanks for the help! ;)

Firstly. I didn't say context played a minute part...I said themes play a very important part. At any rate, we're gonna do it soon, so stop your crying Ashwin and prepare for a fairly large whooping in english, as I've done uptil date. Secondly, no, my name is Chudymaster, one 'd'. So kiss my...

Yeah, this guy is from my school. As you can see, we're tremendously confused.

What does it mean to bring the past to the present in the context of Heaney's poems? Furthermore, I'm having troubles ascertaining the link between the poems Punishment, Funeral Rites and Tollund man and the idea of retreat from the global to the local. That is, I can't exactly identify the two...

DA DA!!! *Rolls out the red carpet* *DRUM ROLL!!* I GOT... 00.00 HAHA, sucked in, I haven't even finished the HSC yet!!

MCLAKE, I worked out our mistakes. You basically did the SAME THING as spice girl, BUT, there's a slight error in how you think about this part... "now n[Ba3(PO4)2] = 2n[(PO4)3-] so n[(PO4)3-] = 2.67 x 10 ^-4 " NO!! You're thinking about it in terms of a mathematical equation. That...

Actually, truth be told, I still don't see why McLake is wrong. And in that case, (because I did the rest the way he did it) could you tell me if these are correct? Finding Sulphate Concentrations: Ba2+ (aq) + SO42- (aq) ---> BaSO4 (s) Mass of BaSO4 (s) = 1.42 g Molar mass of BaSO4 (s)...

You make a good point, thanks for clearing that up before I SUBMITTED MY ASSIGNMENT (mclake!! :))

I'm having a mental conflict here. Mclake made me believe him...but... "Mass phosphate / mass barium phosphate = (94.97 * 2) / 601.9 = 189.94 / 601.84 = .3156 " Could you explain that part?

Well that's part of my method, basically, I first get rid of the sulphates by acidifying the solution. Under these conditions, phosphate will not react. Later on, the water is made alkaline and then the Ba2+ is added to form barium phosphate.

I did for my TDS experiment, but for the anion experiment, I had to test for 3 anions - sulphates, chlorides and phosphates using the same sample, lest I killed myself with impatience. Carrying out such experiments are often long and tedius, so one was enough for the anions one. And I...

...Oh... :( Well I obtained my water from Powell's Creek, in Flemington I think.
