If both magnesium and zinc react with dilute acid, which gas will be common in both reactions?

Answer and explanation

Correct answer: Hydrogen

Magnesium and zinc are both metals above hydrogen in the usual reactivity series, so each can displace hydrogen from a dilute non-oxidising acid. The general reaction is metal + acid → salt + H₂; for example, Zn + 2HCl → ZnCl₂ + H₂. Thus hydrogen is common to both reactions, making option A correct. Carbon dioxide would suggest a carbonate, chlorine requires a different chemical process, and ammonia is not produced in this reaction.
