Re: Cambridge Chemistry ChallengeThe Cambridge website keeps a record of all past months questions with their solutions.(Original post by ElMoro)
Hiya, right now I'm only in year 11 so I can't answer any of the questions!
I would appreciate if someone who does the challenge could keep a record of the questions (and answers) and save them as a pdf so I could look at them next year. Thanks for your time.

search for 'the orbitron' and look at the green shapes closely, if you are any further gold is in 100,000s of ml and rostegentum is...well who dosn't like 100'C? -

Re: Cambridge Chemistry ChallengeNever mind, got it in the end. It took me so long because I left 'orbital' in my answer, and apparently that made it wrong. Quite annoying really.(Original post by Jack-)
I am stumped by the silver question. It gives me 'getting close', but I cant for the life of me think of anything other than f orbital that it could be -

Re: Cambridge Chemistry ChallengeGold Q: Because it's 2 moles of gold for every 2 moles of HCl, do you just work out the moles of gold and carry the number across to use on the HCl - you don't have to divide it to find one mole? None of my figures are being accepted
