Answer:

Gasoline being used in the engine of a car producing exhaust

Explanation:

Hello,

As it is known, gasoline is the component which car engines use to gain energy in order to allow the movement, in such a way, gasoline experiences a combustion chemical reaction, which is a chemical change, induced by the spark that the oxygen provides to allow the combustion. Such chemical process turns both gasoline and oxygen into carbon, nitrogen and sulfur oxides, water, ashes, other side products and the aforesaid energy to move the car.

Best regards.
