What this practice covers
These questions are drawn from past CIE 0654 Co-ordinated Sciences papers and filtered to metals. You answer, you find out immediately whether you were right, and you get the reasoning for the correct option and for each distractor. Wrong answers go to a mistakes locker so you can come back to exactly those.
Practice is free. You need an account only so your progress and your mistakes are still there next time.

What examiners see students get wrong here
These are the errors that cost marks on metals, taken from our own topic notes. Read them before you practise and you will recognise the traps in the questions.
- Leaving carbon and hydrogen out of the reactivity series, and then being unable to answer the extraction question.
- Saying copper reacts with dilute hydrochloric acid to give hydrogen.
- Writing a hydroxide as the product of a metal with steam, or an oxide as the product with cold water.
- Using the top of the series rather than carbon as the dividing line for extraction, so that magnesium is smelted with carbon.
- Saying coke or carbon monoxide is added to make slag. Limestone is.
- Including the ore-reduction equations among the slag-forming ones.
- Saying aluminium is extracted from hematite, or that cryolite is the ore.
- Saying rusting needs only oxygen, or only water.
