EQUATIONS!!
Ones that do contain equations I usually F*ck up to the max.
Am I screwed? Or is it an easy thing to learn?
You are nowhere near "stuffed" as most of them has already told you skillo
The equations in the Prelim book is great. Also, since you still have some time before the HSC starts, maybe you should ask your chem teacher for some year 9/10 general equation sheets (they should have it), like those Metal + Acid ---> Salt + Hydrogen ones? Sounds familiar? Then after you have learnt the general rules, ask them for some past year 9/10 chem TEST paper (or EXAM papers: but you only do the chem section) because they are full of blanky equations to balance. I'm not sure how good/bad you are with equations, but doing that should help you with your primary objective - answer HSC questions.
Okay.. just in case you want to know.. you may ask: why do stupid chem questions? (hopefully you don't) Ultimately you are training yourself to think *chemically* (excuse the pun
) And by doing that you will *understand* the concept of writing chemical equations, thus, applying the method to more complex equations. Remember, they key to do well in any HSC science subjects is to *understand*, not to *remember*.
Say you have already done those things mention above, then if you feel you need more practice, ask your chem teacher for some old year 11 textbooks. The equations in those books are pretty easy. They used to looooove equations and I found a lot of them when I was in year 10. These should take no more than a week if you stick to your plan
So get started now and good luck!

Then well...yes you're pretty much stuffed. If you don't understand equations (the fundamental language of chemistry) then how can you understand chemistry at all? Also how would you balance equations (also required in the HSC)...
Ehh, what are your specific problems with equations exactly? Balancing? balancing simply goes back to the idea of conservation of mass. hence we must have equal moles on both sides of each atom. I'm guessing you're confused on what a mole is...
*sigh*
That sounded pretty harsh... *meanie*
