dayum gurl ;)

Same here! And it. WAS. HORRIBLE.

Of course hehe. Best of luck! ^___^

USyd timetabled mine close to Riproot's version. Not bad.

Cheers brother! Quite early..

The latter. Just make sure you learn the concepts properly and in-depth - make sure you're able to tackle any question they throw at you.

What subjects are you doing at the moment? Name them all.

In my opinion, as long as you take the right approach to learning 4u maths ie. Understanding what you're doing, you should be fine. Don't even attempt to rote-learn because it hardly helps like in my case. If you find 4u difficult, you may consider getting a tutor or dedicating more time to the...

I'm PRETTY sure they take advanced as the 2 english units, even if your marks for 3u and 4u Eng are better. Pretty sure..

Re: Chemistry Calculation questions Post something useful or don't bother.

Re: Chemistry Calculation questions Bump.

I feel left out :cry:

re: HSC Chemistry Marathon Archive Nah when you cover coordinate covalent bonds, it's rather straight-forward. My mistake here was removing an electron from the unbonded pair which you stated wasn't possible rather than the valence electron of the H atom.

re: HSC Chemistry Marathon Archive Ah, I see what you were asking. My bad :/ Yup my mistake. In that case, one of the hydrogen atom's electron is removed and a coordinate covalent bond is made between the oxygen atom and that particular H atom. Still need some work - how embarrassing.

re: HSC Chemistry Marathon Archive Idgi, there is no coordinate covalent bond from what I see in the hydronium ion.

re: HSC Chemistry Marathon Archive Elaborate on "somewhere".

re: HSC Chemistry Marathon Archive What's the electron you're referring to? The one that was in the pair? I agree with the second part though who's to say the non-bonding electrons THEMSELVES split up? If anything, "something" has taken an electron away from the pair - the electrons...

re: HSC Chemistry Marathon Archive I don't think so unless the O atom is involved in a polar covalent bond with F or N, giving it a charge. The O atom alone has no charge so I don't see any attraction occurring between the two. Just what I think.

re: HSC Chemistry Marathon Archive Well since H3O+ is a cation, you know that it has lost an electron. So subtract an electron from the 6 valence electrons of the O atom, that leaves us with 5. So yeah you can see that since we've lost an electron hence a pair of non-bonding electrons is lost...

re: HSC Chemistry Marathon Archive It sure as hell isn't ionic, metallic or coordinate covalent bonding :haha: (My mistake, there is coordinate covalent bonding involved) Awkies.
