What is the chemical equation
Serggg [28]

Chemical equation is the symbolic representation of chemical reactions.

Explanation

Chemical reactions are known as the reaction where two or more molecules or compounds react with each other leading to formation of product compounds along with either release or absorption of energy.

The symbolic representation of the processes occurring in a chemical reaction is termed as chemical equation.

The symbolic representation includes the reactants, products, external energy type and quantity of external energy and also about release of energy if occurs.

So the reactants are usually written in the left side of the chemical equation whereas on the right the products are written.

Both the sides are linked by a single headed arrow mark.

Some both the sides are linked by double heated arrow mark indicating the equilibrium chemical reaction.
