Question

A blank reaction occurs when a substance, usually containing carbon, reacts with oxygen to produce energy in the form of heat and light.

Answer 1

Combustion , I just got this on apex

Answer 2

Answer: The reaction is known as combustion reaction.

Step-by-step explanation:

Combustion reaction is defined as the reaction in which a hydrocarbon reacts with oxygen molecule to produce carbon dioxide gas and water molecule.

For Example: The chemical equation representing the combustion of methane gas follows:

`CH_4+2O_2\rightarrow CO_2+2H_2O+\text{Heat}`

By Stoichiometry of the reaction:

1 mole of methane gas reacts with 2 moles of oxygen gas to produce 1 mole of carbon dioxide gas, 2 moles of water with the release of heat.

Hence, the reaction is known as combustion reaction.
