CH4 + 2O2 = CO2 + 2H2O

The given reaction is type of burning of methane.

Explanation:

Chemical equation:

CH₄ + O₂ → CO₂ + H₂O

Balanced chemical equation:

CH₄ + 2O₂ → CO₂ + 2H₂O

The given reaction is the burning of methane. When oxygen react with methane it produces carbon dioxide and water.

There are equal number of atoms of carbon, oxygen and hydrogen on both side of equation thus this reaction completely follow the law of conservation of mass.

According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.

This law was given by french chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
