Answer:
Combustion reaction
Explanation:
Combustion reaction is a type of chemical reaction which takes place in the presence of oxygen that is it involves burning.
In this reaction, the substance which burns is known as a fuel and yields carbon dioxide, water and heat energy.
The methane gas is present as a component of natural gas and when burned over a bunsen burner reacts with oxygen and yields carbon dioxide and water.
The chemical reaction for the combustion of methane is:
CH₄[g] + 2 O₂[g] -> CO₂[g] + 2 H₂O[g] + energy
Thus, Combustion reaction is the correct answer.
