Hydrogen peroxide breaks down into water and oxygen explain why this is a chemical reaction what are the reactants and products in the reaction?

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.


What describes the reactants and products involved in a reaction?

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.


How are the terns reactant product and chemical reaction related?

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.


A chemical reaction begins with a substance called and ends with substance called?

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.
