Explanation:
Chemical reaction is the way one substance reacts against another. That is, a chemical reaction is that chemical process in which two or more substances, by the action of an energy factor, are converted into other substances. The new substance (s) that are formed usually present a totally different appearance from that of the starting substances.
In a chemical reaction there are the substances that react, that is, the reactants, and the substances produced, called products.
A chemical reaction is represented by a chemical equation. The formulas of the reactants are written on the left, and those of the products on the right, both separated by an arrow indicating the direction of the reaction.
Reactants ⇒ Products
Then, <u><em>the name of the two parts found on the left side of the equation is reactants.</em></u>
