Answer 1

Answer:

1. This is because when crude oil is extracted from the land it is black in color. This resource is compared to gold due to its valuable properties and worth too. ... Crude oil is jet black before purification but after purification, it turns golden in color; therefore, it's tagged as Gold.
2. Coal gas contains a mixture of calorific gases including hydrogen, carbon monoxide, methane, ethylene and volatile hydrocarbons together with small quantities of non-calorific gases such as carbon dioxide and nitrogen.
3. The process breaks up or 'cracks' large molecules. Coke, coal gas, gas carbon, coal tar, ammonia liquor, and coal oil are examples of commercial products historically produced by the destructive distillation of coal.
4. Oil refinery An oil refinery or petroleum refinery is an industrial process plant where crude oil is transformed and refined into more useful products such as petroleum naphtha, gasoline, diesel fuel, asphalt base, heating oil, kerosene, liquefied petroleum gas, jet fuel and fuel oils.
5. Fractional distillation is the separation of a mixture into its component parts, or fractions. Chemical compounds are separated by heating them to a temperature at which one or more fractions of the mixture will vaporize. It uses distillation to fractionate.
6. Petroleum, also called crude oil, is a fossil fuel. Like coal and natural gas, petroleum was formed from the remains of ancient marine organisms, such as plants, algae, and bacteria.
7. The different hydrocarbon components of petroleum are dissolved natural gas , gasoline, benzine , naphtha , kerosene , diesel fuel and light heating oils, heavy heating oils, and finally tars of various weights (see tar and pitch ).
8. Uses of Coal tar Coal tar is used as the medication to heal itching, scaling, and flaking due skin conditions. It is also used in making medicated shampoo to treat dandruff and to kill lice. Soaps are made from coal tar. ... Manufacture paints, synthetic dyes, and photographic materials contain coal tar.
9. Petroleum, also called crude oil, is a fossil fuel. Like coal and natural gas, petroleum was formed from the remains of ancient marine organisms, such as plants, algae, and bacteria. ... Petroleum reservoirs can be found beneath land or the ocean floor. Their crude oil is extracted with giant drilling machines.
