Chemical Reaction

Q. What is a Chemical Reaction?

A chemical reaction occurs when two or more molecules interact with each other. They form bonds and create a new molecule.

In a chemical reaction, the molecules that interact with each other are called reactants and the molecules produced by the reaction are called products. During a chemical reaction, no new atoms are created or destroyed. A reaction could include atoms, ions, compounds or molecules of a single element. The reactants contact each other, bonds between the atoms are destroyed and they rearrange to form new bonds and as a result products are created.
