Expert Solution

answer: A. The reactant in a decomposition reaction must be a compound.

A double displacement reaction, also known as a double replacement reaction or metathesis, is a type of chemical reaction where two compounds react, and the positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products.

A combination reaction (also known as a synthesis reaction) is a reaction where two or more elements or compounds (reactants) combine to form a single compound (product).

A decomposition reaction is a type of chemical reaction in which a single compound breaks down into two or more elements or new compounds.
