rofl doesn't matter m8 i reckon we should just concentrate on the last few exams we got left and then PAARRRRTTTYYYY!!!!

yeah...what the heck isthe haloalkane thing?

i'm HOPING that 3,4,5 are from an option? with the radical, the unpaired lone electron causes extreme reactivity (not sure why) . ozone also has lower MP, BP, stronger oxidiser and is a less stable thing than molecular oxygen i think with the info was also found through analysis of antarctic...

agreed with inasero for eg, in the haber process, the magnetite (Fe3O4) is the catalyst used, and the gases adsorb onto the surface, lowering activation energy and forming products. i do'nt know how it works in reverse reaction..but i'm sure i could get away with just saying that it adsorbs...

i'm not too sur efreakingout... i agree with accuracy - just repeat it, and just more accurate equipment (eg scientered crucible) but i thgouht validity was whether or not the experiment answers the aim...or maybe it's the same thing the difference between quantitative and qualitative is...

hahahaha i got owned :rolleyes: that certainly explains a lot...note to self...never trust a known bs-artist (ppl from my school may know who i'm talking about) thanks

try contacting the actual newspaper, but it was my understanding that if you managed to get your name in the paper, that's a good achievement? or do they put EVERYONE's results there.... :s

if they said for instance that the weak acid ethanoic acid dissociates only 15%, and this was reacted again strong NaOH, you write up the equation - CH3COOH + NaOH <-->CH3COONa + H20, then i the stroichemetric ratio of hydrogen to hydroxy is 1:1. you work out the number of moles assuming...

me too...

is there anyway to work out an "accurate" estimate?

well good luck to all of us but just remember - if we don't get in, there's plenty of alternatives, so best we can do is study hard now - then RELAX~!

hahaha we'll go to any lengths to prove a point

noone? time is running out....

how does using cu/al imrpove it over a beaker? wouldn't that conduct more heat, meaning more heat lost to surroudnings as opposed to more heat conducted through to water?

hahahaha i'm sure that's not the case :p

hey frigid...what's a reagent?

yeah frigid is one of the truly elites here!

ok - one ican answer! distillation works by boiling off liquids right? now, when you're distillationing ( :p ) you're increasing temperature from like 25. therefore, first off, write down the temperatures in order of increasing boiling points. 1 - Methanol (BP 64.7C) 2 - methyl propanoate...

nice work fellas thanks!

do people actually input these values into that uai seeker thing?
