As we drive an automobile, we dont't think about the chemical consumed and produced. prepare a list of the principal chemicals consumed and produced during the operation of an automobile.

Explanation:

In an internal combustion engine operational in automobiles, fuels are converted into mechanical energy in order to move pistons.

The basic reaction in automobile engines is combustion.

     Principal chemicals consumed                 Chemicals produced

                   Petroleum                                           Carbon dioxide

                                                                               Carbon monoxide

                                                                               Nitrogen oxides

                                                                               Sulfur oxides

  In diesel engines, production of particulate carbon is also produced.

Automobiles such as car, truck, motorbikes run on petrol or diesel. While operating these automobiles, combustion of diesel or petrol takes place which in turn requires oxygen for the process to occur.

Operation of the automobiles consumes oxygen, petrol or diesel and releases harmful chemicals like carbon dioxide (CO2), sulphur dioxide (SO2), carbon monoxide (CO) and many more. These chemicals pollutes the air and also affects the survival of living organisms by affecting the respiratory organs.
