nitrogen gas and hydrogen gas
Nitrogen and hydrogen react to form ammonia. This is the reaction in the Haber process, in which the gases are mixed at high pressure and moderately high temperature and passed over an iron catalyst.
The reactants are on the left side of the equation, and the products are on the right side of the equation. The reactants are used up in a chemical reaction, and the products are the substances made by the reaction.
The reactants in this chemical reaction are water and sodium metal.
The substances you have at the beginning of a chemical reaction are the reactants or the reagents.
Reactants
The reactants are hydrogen and nitrogen.

The reactants
The product is hydrogen. to test for hydrogen, take a lighted match or a splint and bring it near the place where you think there is hydrogen and if you hear a squeaky "POP!" there is hydrogen there
The chemical equation Mg + H2S -> MgS + H2.
The reactants in this reaction are sodium (Na) and hydrochloric acid (HCl).
Reactants
Almost any chemical element or compound can participate in some type of chemical reaction and thereby be a reactant. One of the more common reactants is oxygen. It may be that only helium can never be a reactant.
