Question

What do you understand by the following terms

reactants

Answer 1

Definition of reactants

Chemical reactions occur when chemical bonds between atoms are formed or broken. The substances that go into a chemical reaction are called reactants, and the substances produced at the end of the reaction are known as the products.

Explanation

• A reactant is a chemical substance that is present at the start of a chemical reaction and is changed as the chemical reaction proceeds. They could also be referred to as terms like starting materials or reagents.
• the reactants are any substances on the left side of the arrow. The products are any new substance that were produced during the reaction. In a chemical equation, they go on the right side of the arrow.
• bonds in the reactants are broken. new bonds are made in the products.

Example

$\underset{\mathrm{reactant}}{\underset{\mathrm{calcium}\mathrm{carbonate}}{{\mathrm{CaCO}}_3\left(\mathrm{s}\right)}}\stackrel{∆}{\to }\underset{\mathrm{products}}{\underset{\mathrm{calcium}\mathrm{oxide}}{\mathrm{CaO}\left(\mathrm{s}\right)}+\underset{\mathrm{carbon}\mathrm{dioxide}}{{\mathrm{CO}}_2\left(\mathrm{g}\right)}}$
