...is definitely not a base...it is formic (methanoic) acid which is a carboxylic acid

i dont do bio but for some freaky reason i know this..the other one is cytosine

yes...y luv is right...also it IS possible to have negative pH values..just not at all common....

same here

ehhe is that so? i never encountered any naughty stuff....i swear there are so many forum nazis on this board :( anyhows what is VB code and how do i use it?

by neutron bombardment of a molbdenum isotopt in a particle accelerator such as a synchotron Mo(42 98) + n(0 1) ---->Mo(42 99) but this is unstable so subsequent beta decays produce: Mo (42 99)------> Tc (43 99) + e(-1 0) Tc (43 99) is the isotope you are looking for....it is used in...

depends...in normal sea water i dont c y not....cos its not exactly what you would call stagnant...and anyhows im sure the other one quoited there is not gonna happen so whats it gonna be? you dont have much of a choice aye? and theyre not talking bout impressed currents is this...

btw nice thread title? very...er...profound :)

lol agreed

i think youre both right (yewon and shannon) the system you're talking about is not going to happen unless you impress 0.07V of electricity onto it....so....the cathode reaction should in fact be O2 + 4H+ + 4e- ----->2H2O E0=+1.23V hehe now u can stop freaking :)

whats a nerst? "too wise you are too wise you be i see you are too wise for me"

haha i see you are a clumsy one eh? interpret this: YYURYYUBICURYY4ME

lol agreed there...when i was in yr 9 i remember on of the yr 12's swimming in there....that was certainly an impromptu act other ppl amuse themselves by throwing objects such as bins and chairs in there :p

hey wenhui is it true you're bringing nancy to d formal?

look b4 u leap :p

my impression is that it doesnt matter which one is the one which actualy occurs because they both have a more positive E0 than the original electrolysis of water...therefore acidified electrolyte (addition of H+) wil serve to enhace the rate of corrosion

anyhows read carefully theyre different equations...

opps looks like you could be rite....btw i got this from any ol standard reduction potentials table

your cathode equation will become O2 + 4H+ + 4e- ----->2H2O

yes oit does....macmillan has a good discussion of this,.....
