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:

Explanation:

Butane (C₄H₁₀)                   Compound      It's composed by C and H

Dodecane (C₁₂H₂₆)            Compond        It's composed by C and H

Octane (C₈H₁₈)                   Compound      It's composed by C and H

Benzene (C₆H₆)                Compound      It's composed by C and H

Oxygen (O₂)                     Element           It's only oxygen

Carbon dioxide (CO₂)      Compound      It's composed by C and O

Water (H₂O)                      Compound      It's composed by H and O

Gasoline                           Mixture             It's composed by many hydrocarbons

Kerosene                          Mixture            It's a mixture of hydrocarbons
