Q:

What are the reactants in a chemical reaction?

Answer

In a chemical reaction, substances (elements or compounds) called reactants are changed into other substances (compounds or elements) called products. Hence, reactants are those which start the chemical reaction.


 


For example:


1. In the burning of natural gas, methane (CH4) and oxygen (O2) are the reactants in the chemical reaction. are the substances formed by a chemical reaction. In the burning of natural gas, carbon dioxide (CO2) and water (H2O) are the products formed by the reaction.


 


2. H2+O2 ----> H2O


Here H2 & O2 are called Reactants and H2O is called Product.
