Explanation:

Displacement reactions, also called substitution or simple exchange reactions, are those that occur when a single substance (formed by a single element) reacts with a compound substance, "displacing" the latter into a new simple substance. In other words, a chemical reaction in which one element replaces another element in a compound can be categorized as a single displacement reaction.
