Reactants
The starting materials of a chemical reaction are called reactants or reagents.
The substances you have at the beginning of a chemical reaction are called the reactants.
Reactants are the substances that participate in a chemical reaction and are consumed to produce products. They are the starting materials that undergo chemical changes during the reaction.
The starting molecules of a chemical reaction are called "reactants." These reactants undergo a chemical transformation to produce new substances called "products" as a result of the reaction.
The substances evolved after a chemical reaction are called in English products and are not starting substances - the are called reactants.
The starting materials in a chemical reaction are called reactants. These are the substances that undergo a chemical change to form new substances, known as products.
