Mass is conserved in a chemical reaction, so the mass before must equal the mass after. If you have five atoms before, you must have five atoms after.

The breakdown of hydrogen peroxide into water and oxygen is a chemical reaction because it involves the breaking of chemical bonds and the formation of new substances. The reactants in the reaction are hydrogen peroxide (H2O2), and the products are water (H2O) and oxygen gas (O2). This reaction is catalyzed by enzymes in living organisms like catalase.
Reactants are the substances that are consumed or used up in a chemical reaction to form products. Products are the new substances that are formed as a result of the reaction between the reactants.
In a chemical reaction, reactants are the substances that undergo a change to form products. Reactants are written on the left side of a chemical equation, while products are written on the right side. The chemical reaction is the process by which reactants are transformed into products through the breaking and forming of chemical bonds.
Pure substances (or ELEMENTS) form COMPOUNDS after a chemical reaction. For example: Sodium and chlorine, when fused in a chemical reaction become the compound Sodium-Chloride The substance you have in the beginning of a chemical reaction are called reactants and the substance you have when chemical reaction is complete is called products.
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 a chemical equation, the elements/compounds listed on the left side, are the reactants. The right side contains the products of the reaction. eg, 2H2 + O2 = 2H2O. The Hydrogen combines with the Oxygen to from the product, Water.
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 substances produced by a chemical reaction are known as Products. The substances that are reacted are the Reactants.

reactants
The substances you have at the beginning of a chemical reaction are the reactants or the reagents.
Reactants- The substances used up in a reaction. Products- The new substances made.
Reactants are added into the equation to form the chemical reaction. Reactants are substances that are changed into products. Without these reactants, there would be no formula, resulting in no product.
reactants are on the left and the products are on the right
