haha nahh, you seem really smart =\ LOL, have you finished all exams btw? what you intending to do next year in uni? :)

Haha your up late :P How do you think you went in chem. overall?? Could i ask what school you go to? (or if your a selective school students atleast?)

This is exactly, 100% correct. I just looked it up: http://www.finishing.com/173/41.shtml (and also cross-referenced) Thats not general knowledge, how did you know the whole equation + colour change??

LOL @ _deloso, anode half-equation produces H+ (Hydrogen ions)..... Hence, why the solution becomes acidic and litmus papers turns red. (Cathode also produces OH-) Farrout, your friend is F'd btw :P Scaling can't help him, with a raw mark that low!!

Yeahh my school didnt go through pracs. properly aswell. But i read about it somewhere. 0.1 mol/L was considered dilute, hence 0.05 mol/L is def. dilute. This prac. was meant to STRESS the importance of using BRINE (This is just CONC. NaCl) in Electrolytic cells; not just dilute NaCl

I did: Anode: 2H20 --> O2 (g) + 4H+ (aq) + 4e- [Used standard potential tables] Cathode: 2H20 + 2e- --> H2 (g) + 2OH- [Also on standard potential sheet] Looking at the products, this explains for the change of the litmus paper. Btw, Cl2 (g) bleaches litmus paper WHITE Since...

70+ isnt good enough --" i wanted atleast a band 6. ERGHHHHHHHHHHHHHHHHHH, i underperformed in all my exams :( Without Band 6's i will starve; my instiable hunger for success unappeased. Ok i'll shutup LMAO

LOL, crap........................................................... did not seee last one was completiion. Goodbye, it was nice knowing you.

I said 15 LOL . I think its C (you and nav. said it was A). Oswald process, i just talked about temp/pressure required for all of them.... related to equilibrium...then talked about activation energy, particicle colission theory and noted that VERY different exothermic conditions between the 1st...

haha yeahh i found the option topic hard (even though, a few others found it relatively easy) And why is it conc. sulfuric acid?!?!?! Does it act as a dehydrating agent or something, thereby removing the colour of the crystals??

LOL :P hopefully you get a band 6. But hopefully i did better :P HAHAHA nahh, and i rekon 15 multi-choice is c :P

erghhhh. Dont think i did well now ...haha and i think my calcs. are offf now

damnnnnit :( why conc. sulfuric acid?

Ok, for the first question of this option topic, what did you think/say 'X' was? Whats your reasoning? LOL, was so thrown offf by this

Dogs. Whats Atar cut off for B. Science at UNSW? I'm gonna put that one in :) And, luckily my fb didnt delete. Just checked :)

did you read my essay btw? did you like it... be honest LMAOO. Theres always room for imporvement.
