Chemical Reaction

Chemical reaction, the process which transforms one or more substances (reactants molecules or compounds) to 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 converted to form the products hydrogen iodide.
