Detailed explanation-1: -Chemical equations are written with the reactants on the left side of the equation (reaction arrow) and products on the right side of the equation (reaction arrow).

Detailed explanation-2: -The substance(s) to the left of the arrow in a chemical equation are called reactants. A reactant is a substance that is present at the start of a chemical reaction. The substance(s) to the right of the arrow are called products. A product is a substance that is present at the end of a chemical reaction.

Detailed explanation-3: -The position of the reactants and products of a chemical reaction relative to the chemical reaction arrow can be used to identify them: Reactants are always written on the left side of the arrow. Products are always written on the right side of the arrow.

Detailed explanation-4: -In a chemical reaction the reactants (what you start with) are converted into products (what you end with). The reactants, which are shown on the left hand side of an equation, and the products, which are shown of the right, are separated by an arrow.

Detailed explanation-5: -Reactants are those substances that are present on the left side in chemical reactions, these are the raw materials that combine in a chemical reaction to form products.
