Dont forget who came 1st in that new Awesomeness course (yours truly..)

TPG have 400,000 customers. They aint small, top 5 at least. +1 Peerguardian is a great method, but it should also be used in conjunction with private trackers (eg, Demonoid.com, PreToMe.net, etc, and no im not giving out invites, they cost me a fortune in PreToMe lol) I have been inclined...

Haha what can you expect, they're trained in physics, not English or History etc.

Well for 15, doesnt really matter i guess. Even if we are both wrong (unlikely) then its only a mark hah.....im happy with 19/20 lol

Oh thats lucky! I saw 2.5 x 10^2 and got worried....then I saw 0.025 T below and that refreshed my memory hahah That's good, I'm glad I got that right. It was a good question.

Yeah I did something like that, and gave a fair bit of detail. I just wanted to make sure I got the marks, it's pretty likely that detail wasn't required. omfg! I didnt put a heading on... If they deduct marks for that, I will spaz out.

Hey I might have actually gotten that question right (against all odds!) I thought I was way off, but I remember using that equation and making S=0. Then I got two answers for t t=0 and t=something else So yeah, sweet....

Haha I did the same thing. I had a software exam that went till 5PM yesterday, so I had no time whatsoever to cram... lol! Overall, pleased with the exam.

Good idea. Dont worry, I did the same thing as you, I had a good decent response and forgot to mention Australia. And I'm sure many other people did exactly the same thing too lol.

Think about it. Electron has it's charge q Positron is electrons anti-particle, having the opposite charge. A proton is basically a neutron (no charge) + a positron (opposite charge of electron) Therefore, the charge on a proton is opposite that of an electron! :D

OK guys, I'm 100% confident in all my answers and I'm pretty good at this subject. According to the information in this thread, and some quick book re-reading, pretty sure these are the correct answers: 1.A 2.C 3.D 4.B 5.B 6.C 7.D 8.D 9.B 10.B 11.C 12.A 13.D 14.C 15.A 16.B 17.C 18.A 19.C 20.D...

HSC Excel Chemistry (latest edition). Absolutely fantastic and concise, exactly how I like my information. For when I didn't understand something, I referred to my Conquering Chemistry book for the detail. I strongly recommend Excel books though, if it weren't for them I'd have failed my HSC lol!

I did the EXACT same thing. lol silly us

Haha that is true! Didnt even realise. :)

Main uses of Sulfuric Acid include: Electrolyte in Car Batteries (Think about all the cars out there..) Steel Manufacture (Pickling) Fertilisers From Wikipedia: "Principal uses include lead-acid batteries for cars and other vehicles, ore processing, fertilizer manufacturing, oil refining...

I'm reading my Excel (latest edition). It doesn't say anything about pH, Calcium Hydroxide, or anything of the sort. I'm not saying you're lying, I just think that it's annoying how these sources all contradict each other! =P Thanks :)

I'm reading the Excel book NOW. It says PH adjustment is basically last. It says Flocc>Sedi>PH Guess I'm right, 11D.

Excel here says the process as follows: The Catchment Area Screening (large matter screened out) Coagulation/Flocculation/Sedimentation Filtration (sand bed) Oxidation (such as adding chlorine dioxide, or ozone) Water Stabilization (pH chemically stabilised, by adding lime or sometimes CO2)...

Dont stress, you've covered most of it. 1 mark at most you've lost. Hell, those who did mention it seemed to not know which one it is anyway..... Good reasoning, however I'm reading here in my Excel book for LDPE ; "It is readily melted and moulded and is used to produce such items as...

That was my reasoning as well.
