Cambridge Chemistry Challenge

Well, copper is causing me a lot of pain. Doesn't help that it's the middle of the night either...

if i could find the amount of energy required to heat 1kg of air i would be able to do it :P it really is to late/early to do this -.-

I've gone as far as deciphering that the volume of the room is 150m³. Other than that I'm lost. Can't believe that someone has already completed it

4 somebodies actually

I know right? I'm a little jealous to be honest If this is how hard copper is, I hate to think how hard the rest are...

plus there is the fact that no matter what i do the answer is wrong its frustrating... but i will get it eventually... still... i cant understand how you are meant to work this out

I find it frustrating too - chemistry calculations aren't my strong point either, so I might have to sleep it out and try again tomorrow. It will get to the point though where I will get distracted by this and not do any schoolwork, haha.

yeah haha but it would be awesome to do it in the first few hours though... i think im close to doing copper though

anybody on gold?

Rg is fiendish!

okay what is silver going on about 0_o it makes absolutely no sense to me

help please. im stuck on copper
