Crude oil may contain hundreds of different types of hydrocarbons. some examples include: butane(c4h10) dodecane (c12h26) octane (c8h18) benzene (c6h6) many common fuels, such as gasoline and kerosene, are combinations of these substances or others. when these fuels burn, they combine with oxygen (o2) to produce carbon dioxide (co2) and water (h2o). identify each of the highlighted materials as an element, a compound, or a mixture, and explain your reasoning.

The answer to your question is below

Explanation:

Material             Classification               Reason

Crude oil             Mixture                         Because we know that crude oil

                                                                 is composed of different substances.

Butane                Compound                   Because it is composed of carbon

                                                                 and hydrogen

Dodecane           Compound                  Because it is composed of carbon

                                                                and hydrogen.

Octane                Compound                  Because it is composed of carbon and

                                                                 hydrogen.

Benzene              Compound                  It is also composed of carbon and

                                                                 hydrogen.

Gasoline              Mixture                         It is a combination of hydrocarbons

Kerosene             Mixture                        It is a combination of hydrocarbons

Oxygen                Element                       We can find it in the periodic table.

Carbon dioxide   Compound                   It is composed of carbon and oxygen.

Water                   Compound                   It is composed of hydrogen and        

                                                                  oxygen.
