Balanced:

Pb(NO3)2 + 2KI = 2KNO3 + PbI2

Na2CO3 + HCl -> H2O + CO2 + NaCl

Balanced:

Na2CO3 + 2HCl = H2O + CO2 + 2NaCl

thanks a million

No probs - brought back some old memories. :lol:

You can do my homework as well if you like.

It involves animating a badly modelled 3D man :(

I think you're on you're own there... :unsure:

I'm currently re-teaching my 11 year old son geometry. I don't know how they expect kids to understand area and perimeter the way they teach it. :angry:

I did Chemistry at school, maybe 10 years ago, and recall doing those equations. I could never have remembered how to do them like that.

Nice one, Nikki :beerchug:

Thank you :)

My brain hurts. I need to lie down now. :wacko:

:lol:

When I said doing "this", I didn't mean balancing equations, I meant chemistry. A university course in chemistry is a lot harder than this stuff :lol:

I don't do chemistry any more :no: , hence my stupidity above

I never did chemistry, we made moonshine and swaped the gas and water hoses, then I spent my last 2 terms being sent to the headmasters office for stuff other people did :dry:

So this thread might as well be japanese :ermm:

Altho Japanese is easier to learn :ph34r:

Jonno :cool:
