A fire or explosion is an example of a fast ________________ reaction.

Explanation:
Fires and explosions are driven by rapid oxidation—the fuel reacts quickly with an oxidizer (usually oxygen in the air), transferring electrons and releasing heat and light. This fast chemical change is what makes the event a fast oxidation reaction. While combustion is the broad term many use for fires, the essential chemistry is the rapid oxidation taking place. Polymerization involves building long molecular chains and isn’t what powers a flame, and reduction would mean gaining electrons, which is not what happens during combustion.
