Question

1. if a fire occurs inside of your microwave, you should simply shut the door and not open it because the lack of _____ will naturally put out the flames.

options: grease, attention, nitrogen, oxygen

Explanation:

Fire requires oxygen to burn (combustion needs oxygen as a reactant). Shutting the microwave door limits oxygen supply. Grease fuels fire, attention isn’t a chemical requirement, and nitrogen isn’t the key reactant for combustion here. So the lack of oxygen extinguishes the fire.

Answer:

D. oxygen
