Final answer:
Iron reacts with hydrochloric acid in a single displacement reaction to produce iron(II) chloride and hydrogen gas.
Step-by-step explanation:
The reaction between iron (Fe) and hydrochloric acid (HCl) is a type of single displacement reaction, also known as a substitution reaction. In this chemical process, iron displaces hydrogen from hydrochloric acid, leading to the formation of iron(II) chloride (FeCl2) and hydrogen gas (H2). The iron reacts with the acid to form iron chloride and hydrogen gas, with the gas often observed as bubbles. There is a typo in the provided chemical equation where iron(III) chloride (FeCl3) is mistakenly indicated instead of iron(II) chloride (FeCl2). The correct balanced chemical equation for the reaction should be: Fe(s) + 2HCl(aq) → FeCl2(aq) + H2(g).
