Answer: E. Occurs when methane gas is burned.

Explanation:

A chemical change occurs when matter undergoes a change to form a new substance with different chemical properties, and the reaction is usually not reversible.

In the case of burning methane gas (CH4), oxygen and methane are the reactants, while the new substance formed from the reaction are carbondioxide (CO2) and water (H2O).
