Magnesium reacts faster with an acid than iron does. What does this show?
Answer and explanation
Correct answer: Magnesium is more reactive than iron
The governing concept is the reactivity series of metals. Under comparable conditions, a metal that reacts more rapidly with an acid generally has a greater tendency to lose electrons and displace hydrogen. Magnesium lies above iron in the reactivity series, so it usually produces hydrogen more quickly. The observation does not make iron incapable of reacting, does not classify magnesium as a non-metal, and does not show equal reactivity.
