Answer :

Final answer:

Petroleum is a valuable mixture of organic compounds known as black gold, from which various useful products are derived through the refining process.


Explanation:

Petroleum Composition: Petroleum is a mixture of organic compounds, primarily containing hydrocarbons such as alkanes, cycloalkanes, alkenes, and aromatic hydrocarbons with varying carbon chain lengths.

Why Petroleum is Referred to as "Black Gold": Petroleum is called "black gold" due to its economic value and the wide range of useful products that can be derived from it, including gasoline, diesel fuel, plastics, and petrochemicals.

Obtaining Petrochemicals: Petrochemicals are obtained through the process of refining crude oil, where its constituents are separated by chain length to produce products like gasoline, kerosene, diesel, and petrochemical feedstock for plastics and other materials.
