The correct description of the reaction between zinc metal and hydrochloric acid (HCl) is:
**A single replacement reaction takes place because zinc is more reactive than hydrogen.**
In this reaction, zinc (Zn) displaces hydrogen (H) from hydrochloric acid, producing zinc chloride (ZnCl₂) and hydrogen gas (H₂). This type of reaction is classified as a single replacement reaction because one element (zinc) replaces another element (hydrogen) in a compound (HCl). Zinc is indeed more reactive than hydrogen, which allows it to displace hydrogen from the acid.
