See it on the paper →The response for A was widely known, less so for B, condensation. Incorrect answers for B included boiling and evaporation. Both responses are changes form liquid to gas, not gas to liquid as shown in the diagram.
— Examiner report, May/June 2025, 0653/31 Q4(a) (Cambridge)
A small number of candidates chose the correct answer, A. Candidates are expected to know that copper is low in the reactivity series and that it does not react with dilute hydrochloric acid.
— Examiner report, October/November 2023, 0653/12 Q24 (Cambridge)
Several candidates explained that carbon is unable to displace aluminium from its compound because aluminium is more reactive than carbon. These candidates gained credit. Incorrect responses included the statement that aluminium is less reactive than carbon. Most of the lowerscoring candidates did not attempt this question.
