The chemical reaction that occurs when gasoline and air are ignited is called the combustion reaction.

It is generally known as burning.

Explanation: Combustion reaction is a chemical reaction between an carbon containing compound (Organic compounds) and oxygen to form water and carbon dioxide. It is always in the presence of oxygen. This reaction is an exothermic reaction, it means it releases energy in form of heat. In engines, gasoline which is an organic compound reaction with oxygen and give carbon dioxide and water with an appropriate amount of heat energy. This heat energy is used to run the engine of vehicle.

Answer: combustion reaction.

Explanation:

Gasoline is a mixture of hydrocarbons (with some other dded substances in minor proportion).

Assuming a hypothetical composition of the gasoline as C₅H₁₂ (only for explanation purposes), the chemical reaction that occurs when gasoline is burned is represented by:

2C₅H₁₂ + 16O₂ → 10CO₂ + 12H₂O + energy.

Combustion is a special type of chemical reaction, in which oxygen combines with other substance (element or compound) releasing a large amount of energy in the form of heat and light. It is a very common reaction of the hydrocarbons and the products are carbon dioxide and water in the form of vapor.

The combustion of carbon (C) is a very important and common reaction that has been using to produce energy: C (s) + O₂ (g) → CO₂ (g)
