Question

Define reactants.

Answer 1

• Reactants: Reactants are those chemical substances that react together to form a new substance during a chemical reaction.
• Reactants are always present on the left side of the arrow in a chemical reaction.
• Example: $\underset{\mathrm{Carbon}}{\mathrm{C}}+\underset{\mathrm{Oxygen}}{{\mathrm{O}}_2}\to \underset{\mathrm{Carbon}\mathrm{dioxide}}{{\mathrm{CO}}_2}$
• Here carbon and oxygen react to form carbon dioxide. Hence, carbon and oxygen are reactants.
