rofl i found mistakes in the excel at the local library but then again it wasnt the latest edition >_> i dont think any supplimentry textbooks are needed for the prelim year if you must start buying for the hsc year

Basic Rules in naming hydro carbons find the longest possible chain then you start counting from the end carbon closest to 1. triple/double bonds if not then 2. side branches if not then 3. halogens when writing out the formula except for the lets say octan-4-ol everything else is sorted...

well for an overall equation from start to finish .... U --> Xe- + YHe + Pb where X is the number of beta decays and Y is the number of alpha decays? although i think this method is slightly dodgy i believe it answers the question

just a quick side note to help you remember proper time is always with improper distance and proper distance is always with improper time

having extra information is never a bad thing it adds depth to your answer good textbooks in my opinion are ... jacaranda physics in context bad ones are excel

yes .. i heard the maths in electrical is crazy .. oh well mine is ... 5 or 6 years full time + 1 or 2 year internships depending on whether or not i choose to do one for each

i know =D but i got through engineering studies quite well with only my knowledge of chemistry and physics since calculations dont go much further than prelim =D the jump to uni will be noticable but we'll see how it goes which uni and are you doing a double degree? im planning on uts...

you needent have done this experiment yourself as long as you can give a discussion on it easy solution .. drop a ball ... if it lands directly below where it was dropped .. inertial frame otherwise non inertial

hahhahahhaa engineering physics chem and maths nice =D all 4 overlap to some extent lololol *speaks from experience* since you have 13 you have a back up incase you screw one of your exams over so i would keep it unless you think studying for the subject is taking up too much time although IMO...

nothing in year 11 is assessable and if it is you go back over it in year 12 anyway :P

^ the first part of your post is correct but the second part is wrong because electrons have NEGATIVE CHARGE a gain in electrons lowers the charge

.... you lie .. there will always be time for video games dota at least once a night keeps you happy

so you can reduce molecules :P ok then thanks duckie

.... simple solution do whatever you want to if school doesnt offer the courses you want then head off to tafe or start an apprenticeship

nothing beats the 'ban dihydrogen monooxide'

i dont think its considered reduction but then again i havent done this in a while as far as i know its the ATOMS which are reduced/oxidised and not the molecule as a whole? anyway reduction is where the valance changes/becomes more negative but the valence of H is still +1 and the valence on...

its not so bad ... all my assessments were worth 25% each ... even the pracs >_> i failed one so ye =) but im still confident in my physics anyway shouldnt this be in the general physics and not in space?

3 marks = 5 points

the easiest experiment would be the pendulum experiment since its the most commonly seen even in exams they would rarely give a different example (if there are any) i did that one at home actually >_>

LOL =) nice one
