Answer:
A chemical equation is a symbolic representation of a chemical reaction in which the reactants and products are denoted by their respective chemical formulae.
Step-by-step explanation:
A chemical equation is a shorthand way of representing a chemical reaction. It uses chemical symbols and formulas to show what happens in a chemical reaction, including the reactants and the products that are formed.
The reactants are the substances that are present at the beginning of a reaction, and the products are the substances that are formed at the end of the reaction. In a chemical equation, the reactants are written on the left-hand side of the equation, and the products are written on the right-hand side of the equation.
