Chemical reactions are processes in which atoms rearrange to form new substances. This occurs when two or more substances, known as reactants, interact to produce one or more different substances, called products. During a chemical reaction, the bonds between atoms in the reactants are broken and new bonds are formed to create the products. Chemical reactions are represented by chemical equations, which use letters and numbers to show the types and number of atoms involved in the reaction.
