Very useful, but in regards to quesion 6/7:
6. What do we call a chemical that contains a metal, carbon and oxygen only?
7. Give an example of the above.
Do you mean metal carbonyls? Surely not at KS3.

Useful and challenging questions. Would be great if you could also supply an answer sheet to make this a 'straight off the shelf' activity. Minor point - ammonium sulfate appears twice in question 12 - guessing first appearance should be an easier example?
