Not sure, google would be your best friend here, unless one of the PhD chem guys on here casually know the answer to this lol

Yeah, fractional distillation is the best method you would have access to.

True, but I'm not sure how the high school would expect you to use gas chroma. or nmr for a y12 practical...

For fermentation to occur, you MUST have the following conditions: an anaerobic environment --> this forces the yeast to produce ethanol as opposed to ATP when they try to respirate (similar to how your body produces lactic acid when you are running on low oxygen) The reaction container should...

Both of these are correct in the HSC. I have used both in tests and they have been marked correctly, though, it is odd saying "concentration of water increases" (it's more the concentration of water molecules relative to other molecules that increases, but saying the latter is understood by...

Your thinking is correct. The formula q = mcΔT gives you the heat energy released (this can be positive or negative depending on the value of ΔT). The formula for enthalpy change is actually ΔH = -q/n which means that when you put in a q value >0 you will get a negative ΔH. This makes sense...

Oh LMAO. Maybe it would help applying then. Depending on your university, they will apply for HECS for you as part of the enrolment process. That's why it's best to wait until Monday and call your uni. Good luck.

Ok well here's the advice I would give you: DON'T PANIC at all because you have until the census date (31st of March) to sort out payments and such. Instead research HECS, try and see why your application was declined, or wait until Monday and call your university so you can get some advice. It...

hoooold up. so was your application for HECS successful or not? also WHY are you paying 12K a month if you aren't international?

You do have a TFN. Everyone has a TFN. Ask your parents for your TFN and, in case you didn't know, never share it with anyone as it is very VERY sensitive. It's completely normal to have classes at the same time. For semester 1 I have three classes all at the same time. The lectures will be...

Yuh I got full compilation of mod 5, 6, & 7 questions with solutions. If you're interested just email me at: lennon.blueberries@gmail.com

As I said above, resorting to the internet for the opinion of strangers will have zero effect on your performance. At most people can offer you encouragement and say "don't give up" or "persevere". I have no idea what school you go to, how smart the guys and gals above you are, and how...

Ok. Well, I'm sure you can get 90+ easily then if you stop being lazy. At the end of the day, a stranger on the internet can't predict your future. You know your abilities best. All the best.

How good are the people above you? Ideally, you'd want to pull yourself up to top 5. It really depends on the strength of your class. For instance, if you're last in a class of 15 people who are really great at math, then you'll do great. My music 2 class was like 10 people large and we all did...

If you don't mind, what are your ranks and do you have large-sized cohorts for each subject? Also, are you going to just give up or are you willing to work hard and persevere?

If it's not too late try calling 1800 793 864 to get student support. However, the prerequisites are usually recommended, which means if you haven't done the prerequisite you can take a bridging course to fill your knowledge gaps or, if you're comfortable, you can just go with the flow and do...

oh lol I just realised it got bleeped. Here's a link to the textbook I was referring to: click here once again, I recommend you use the well-known textbooks and the syllabus concurrently for self-studying in detail. The book in the link above is good for initial familiarisation.

********* chemistry is best for self-learning, but in terms of HSC detail it is VERY surface level.

alright, thanks!
