Answer 2

Oxygen is required for combustion.

Explanation:

Combustion is also known as burning.

Oxygen is required for combustion because oxygen supports the chemical process which occures during fire. When anything burns, it reacts with oxygen from surrounding air, releases heat and generates combustion products (gases, smoke etc.).

Combustion is a high temperature exothermic redox chemical reaction between fuel and an oxidant, that produce oxidized and gaseous products, in a mixture called smoke.
