Question

a reaction which forms a solid product is an example of a(n):
a gas evolution reaction.
b combustion reaction.
c precipitation reaction.
d oxidation - reduction reaction.

Explanation:

A precipitation reaction is defined as a chemical reaction that results in the formation of a solid (precipitate) from two aqueous - phase reactants. A gas - evolution reaction forms a gas, a combustion reaction involves burning in the presence of oxygen, and an oxidation - reduction reaction involves a transfer of electrons.

Answer:

C. precipitation reaction
