Crude oil may contain hundreds of different types of hydrocarbons. Some examples include:
- Butane $\left( C _4 H _{10}\right)$
- Dodecane $\left( C _{12} H _{26}\right)$
- Octane $\left( C _8 H _{18}\right)$
- Benzene ( $C _6 H _6$ )
Many common fuels, such as gasoline and kerosene, are combinations of these substances or others. When these fuels burn, they combine with oxygen $\left( O _2\right)$ to produce carbon dioxide $\left( CO _2\right)$ and water ( $H _2 O$ ).
Identify each of the highlighted materials as an element, a compound, or a mixture, and explain your reasoning.
