Answer:
The burning of gasoline in an automobile engine is an example of an <u><em>exothermic reaction</em></u>.
Explanation:
Energy is the ability to perform a job or to produce heat. Chemical reactions involve a rearrangement of atoms between substances with rupture or formation of chemical bonds and this generates changes in the energy of the system.
An exothermic reaction is that reaction where heat is released.
An endothermic reaction is that chemical reaction that, when it occurs, consumes energy.
Combustion means the process by which the burning of any substance, whether gaseous, liquid or solid, occurs.
When a car's gasoline burns, it reacts with oxygen from the air and releases energy to drive the vehicle. During combustion, the carbon and hydrogen atoms of gasoline react with the air atoms. Thus carbon monoxide (CO), carbon dioxide (C02) and water vapor (H20) are formed.
During the burning of gasoline in a car, energy is released to drive the vehicle. Then it is an exothermic process.
