Look at the chemical equation shown below. A, B, X, and Y represent different elements or polyatomic ions.

AX + BY → BX + AY

Which of the following types of reactions could be represented by this equation?

A single replacement reaction

A decomposition reaction

A synthesis reaction

An acid-base reaction

The answer to your question is an acid base reaction

Explanation:

A single replacement reaction is a reaction in which one metal replaces the cation of a compound. The reaction of this problem is not of this type because here the reactants are compounds no single elements.

A decomposition reaction is a reaction in which one compound decomposes into two or more products. This is not the answer to this question because in this reaction there are two reactants not only one.

A synthesis reaction is a reaction in which two reactants form only one product. The reaction of this problem is not of this type because there are two products not only one.

An acid-base reaction is a kind of double replacement reaction. In some acid-base reactions, there is an interchange of cations and anions like is shown in this reaction.
