Answer:
C)activator
Step-by-step explanation:
A chemical reaction can be defined as the reaction between the atoms of two or more chemical elements to produce (form) a compound.
Generally, catalysts are used in laboratories to speed up the rate of a chemical reaction. Thus, they are also referred to as oxidizing agents and a common example is the chemical element oxygen.
Activation simply involves the process of making a reaction active or effective.
Hence, the oxidizer that is added to hydrogen peroxide to increase its chemical action is known as the activator.
