Reactants and Products in Chemical Reactions. In a chemical reaction, substances (elements and/or compounds) called reactants are changed into other substances (compounds and/or elements) called products. You canât change one element into another in a chemical reaction â that happens in nuclear reactions.
The vast majority of reactions include two or more reactants that react to give one or more products. One simple example of a reaction in which two reactants produce a single product is the reaction of the acid, hydrochloric acid (HCl), and the base, ammonia (NH3). When these two reactants are mixed with one another the reaction produces ammonium chloride (NH4 Cl).
