Question

Rapid oxidation of a substance accompanied by the production of heat and light is _______________. a) Combustion b) Decay c) Erosion d) Melting

Answer 1

The rapid oxidation of a substance accompanied by the production of heat and light is called combustion. Hence option A is the correct option.

Step-by-step explanation:

Combustion is the rapid oxidation of a substance accompanied by the production of heat and light. Combustion is a chemical reaction that involves the combination of molecules of fuel with molecules of oxygen, resulting in the release of energy in the form of light and heat.

For example, when burning methane on a kitchen stove, methane (CH4) combines with oxygen (O2) to produce carbon dioxide (CO2), water (H2O), flame, and heat:

`CH_4 + 2O_2 --- > CO_2 + 2H_2O + heat`
