Expert Answer:

A chemical reaction is a process that leads to the transformation of one set of chemical substances to another.

Example: Burning of magnesium in oxygen to form magnesium oxide.

This is a chemical reaction because reactants react with each other to form the products which have different characteristics from reactants.

A chemical equation represents a chemical reaction.

Example: 2Mg+O22MgO

The chemical reaction written in word can be expressed in terms of formula of reactants and products in chemical equation.
