I didn't say change in volume for the last one- I sated that all concentration had been reduced, but one had been changed by the most.

Guys (and girls), I don't think some of you are thinking. LDE makes plastic bags for shopping. Imagine carrying water in that! HDPE is the safe option here. They can't fault you for saying HDPE, because HDPE is used in milk bottles- aka a type of bottle. EDIT: OP, question said NATURAL RAW...

Yeah I got 1.77% also. What my friend say he did was that he interpreted Nitrogen as just N and not N2, so that's why he got 2.16%

That's not pH balancing though. pH balancing refers to adding acids and bases at the end to get your ideal pH. Also, whilst we're on the topic, how the fck does everyone remember their answers so well?

Bad luck I guess to people who didn't get Electrical and Actuarial. Those are usually the hardest to get into. Especially Actuarial. And when someone said 100 UAI Ruse kids are applying...those kids apply every year. 100UAI =/= Medicine lol. In fact, someone from my school who got 100 UAI a...

I loved that test. The 6 markers were science questions! Honest to god, ACTUAL CHEMISTRY QUESTIONS. Glad to see the Board is at least trying to set a science exam and not a history/social science one. For the 6 marker on equilibrium, i got temperature increase in the first one, CO decreases...

Chemical + Electrical engineering interviews xD

Nice trolling you got there. All nitrates are soluble.

One word; experience.

I think O might be lying, or his/her teacher might be atleast...why would they be briefed on marking right now? HSC ain't even over.

Wow. ITT, impatient people. I got sent an email from UNSW saying that tdue to technical issues, they're sending out decisions on 2nd November, aka Monday. Now everyone, go back to being less nervous.

That's wrong right there. 1) Ionic substances don't form molecules 2) You can't change the molecular weight of something unless you add new atoms or subatomic particles to it. 3) Hygroscopic is a better way to describe NaOH's deliquescent properties- and this changes the mass that you measure...

Re: What will be this years band 6 be for bio In this thread: a lot of woolly guesswork. Honestly, you guys should stop guessing as to what a band 6 cut-off is.

I wrote about Dolly too. It's valid. I wrote that the advantages are mostly economical- because if we replicate a sheep with good characteristics, such as good wool yields, farmers can get more money etc. For the 7 marker, I did what others did, where I rambled on what gene mutations, base...

This is what I thought. This was a real case of "best" answer. A mixed b and C together, so it was the best choice.

I don't think you can just say that. I differentiated and found a value that gives minimum again. But it was greater than 5, so I said since the doman of x is x must be less than or equal to 5, and x=5 cost in minimum.

Cambridge Maths Textbook would be your best bet.

Hi everybody. So currently I'm just working my way through the Success One Physics Book- just for some overall revision before trials. But as I'm doing this, I'm seeing a lot of very strange questions on the "specimen" questions section for Astrophysics. The style is very simple and vague-...

What do you mean subjects? Also, I know America is full paying, but there are a lot of scholarships and stuff for scores as good as yours mate!

Mate, why didn't you apply to unis overseas? You would have EASILY gotten in with your marks. We're talking Harvard, Stanford etc. with scholarships!
