i forgot the equations that go with that! so i made them up :(

i guess someone was right :p

yeah, i noticed that they seemed to cover less than i expected because they had a lot of fairly large mark questions.

hah, yeah, i'm so completely relying on this being scaled :p

i was only completely thrown off by like 1 or 2 wuestions. everything else i had some idea about. i wrote a lot anyway, but that isn't saying much....

went to bed at 5. the exam seemed ok. really could've been better, but chem was never my best best subject anyway

i'd be happy with 80's. but i dunno... i really can't tell i go in exams o_O

slept from 5-7. stupid birds.... already chirping when i was trying to go to sleep. oh well, considering i only saw some material from the second half of my option for the first time at 4 am, i think i went ok

still here

wow. last one here. i am the true queen of crammers. give me an award :(

is it greater or less than that of a normal fuel, say octane?

and how does this relate to redox reactions?

hmm.... we had this in one of our assessments *goes to dig out the paper and see what the perfect answer would be*

phew... cos oxidation states are those things you use to figure out whether a reaction is a redox one or not... i've never understood HOW exactly you use them to do that, but i know that you do.... something about change in numbers..... any help anyone?

by oxidation state, do you mean reduction potential??

goodnight. wish i could do the same, but many miles to go before i sleep as they say. good luck to you too, although you probably need it less than me :p

general overview (i compared fuel and dry cells) dry cell = cheapest, easy to store, good for daily use BUT = non-rechargeable, getting outdated, not a lot of energy produced impact = first commercial batter, portable source of energy, freed ppl up. envirnomentally pretty nasty - components...

hah, thanks, and it's ok. now if only i could somehow have a moment of enlightment....

probably. i think in our school exams we've had half marks deducted. usually you know from the context of the equation. cos for most equations you'd be using, you'd know what they represent... well, in a perfect world....

*is planning to combine all of the above* :D man, coming down off that would be crazy. just be walking along the street, then suddenly, BOOM, you're asleep
