What is Chemical Reaction?

A chemical reaction is a process that transforms one or more substances (reactants molecules or compounds) into different types of substances or products by rearrangement of the electronic configuration of constituents atoms present in the reacting elements.

For example, hydrogen reacts with iodine to form the hydrogen iodide molecule. In this chemical reaction, hydrogen and iodine atoms are converted to form the product hydrogen iodide.
