I hope that was exaggeration, because you've only got 11 units :jaw:

Moles = mass/molar mass (solids) Moles = concentration x volume (solutions) Moles = volume/molar volume (gases) *Note*- molar volume at STP is 22.71, at RTP is 24.79 Moles = no. of atoms / 6.022x1023

This was in my half yearlies. They LOVE the simple answer. Basically what you had to do for 5 marks was: - Define what amphiprotic substance means - Show that dihydrogen phosphate can act as an acid or base using equations - State that dihydrogen phosphate is more likely to act as a base (we...

lol, Ag is silver.

Depends if you go to James Ruse or St. minijumbuk Catholic School.

That's why you DON'T hint at friends =\ It's kinda called cheating =O See? You just disadvantaged yourself. Now she might get a better rank than you, and end up getting a higher assessment mark in the HSC =O

Sorry to say, chances are pretty bleak. I'd advise spending more time on physics to improve it, because it's the hardest course you're doing, and obviously hardest to ace without effort. If done well, it can bring up your UAI quite well. But it doesn't look like you're the maths/science sort of...

Depends what the question is, really. But I would just tell the all the stuff I know regarding the question, just basically listing things, explaining/elaborating, evaluating/assessing (if that was the question) until you exceed the lines given by like 2 or 3 lines. Some questions that tell...

Why isn't it helping? What part did you not understand?

It's not a good idea to associate dipole-dipole attraction forces with the intermolecular forces within H2O. They have a different classification for 3 specific atoms which form "Hydrogen bondings" with H. These are the F, N, and O. They are given the term "H- bonding" because those 3 elements...

I WIN! =D Haha.

Just a careless mistake, but to avoid confusion, benji: 0.05L is 50 mL, not 15 mL

Neither of a) nor b) make any sense. This question was either poorly worded, or some hints were not shown. How can anyone know what the value of x is? I mean, sure you can solve it and then come up with a square root of negative, but that still only shows the value of x, not actually proving the...

Wow. That's....amazing! =O I believe English Extension 2 is lower scaling than Extension 1.

I sooo wanna try 4u chem xD But yea dude, if you get 0 in an exam, you should definitely drop. Personally, I'd just drop even if I had 30% average.

Well, I'd never kiss a girl unless I liked her and knew she liked me.

What would be the range for an English essay for a band 4, 5, and 6? I'm getting shitty ranks and shitty marks... My average is probably around 12/20 My rank is 121/166. My school was around rank 65 last year. I entered that on the calculator, and it came up with a horrendous bottom 27th...

Try make her go a bit jealous; don't make her grow TOO jealous though. Talk to some more girls, but not enough for her to think you're flirting. Give her the feeling that you only have 1 girl on your mind, and that girl is her. This way, it'll make her feel that you're not that kind of guy...

I thought detergents don't form scum in hard water though =O
