reactants or reagents are the elements or compounds that go into a chemical reaction.
the elements or compounds that go into a chemical reaction are?
reactants or reagents
the substance (or substances) initially involved in a chemical reaction are called reactants or reagents. chemical reactions are usually characterized by a chemical change, and they yield one or more products, which usually have properties different from the reactants. reactions often consist of a sequence of individual sub-steps, the so-called elementary reactions, and the information on the precise course of action is part of the reaction mechanism. chemical reactions are described with chemical equations, which symbolically present the starting materials, end products, and sometimes intermediate products and reaction conditions.
