Answer:

A chemical equation is a written statement that uses chemical symbols and chemical formulas instead of words to describe the changes that occur in chemical reactions.

The following example, shows the contrast between a word description of a chemical reaction and a chemical equation for the same reaction.

Word description – Calcium sulfide reacts with water to produce calcium oxide and hydrogen sulfide

Chemical equation – CaS + H2O → CaO + H2S
