Question

The main component of natural gas is?
A.) Carbon dioxide
B.) Carbon monoxide
C.) Oxygen
D.) Methane

Answer 1

Hint: Natural gases are mixtures of hydrocarbons and they are used for the fuel and raw material for the production of different materials.

Complete step by step answer:

Natural gas is a mixture of hydrocarbons. The main component of natural gas is methane. It is around 98% of the natural gas mixture. So, the correct option is (D).

Additional information:

Natural gas is widely used as a fuel and a raw material. It contains mainly methane, ethane, propane, butane and so on. Some studies show that less amount of carbon dioxide and hydrogen sulphide are also present in natural gases.
Natural gases are fossil energy sources that were generated years ago beneath the earth’s surface. These natural gasses contain natural gas liquids and non-hydrocarbon gases. Millions of years ago, the animals, trees, aquatic organisms formed a layer and were buried under sand. These carbon and hydrogen rich materials turned into coal, petroleum products and natural gases due to high pressure and heat.
Conventional natural gas found in the spaces between layers of overlying rocks. Unconventional natural gases are recovered from the tiny pores of sand stone and sedimentary rocks. Associated natural gases found with the crude oil. Coalbed methane is a type of natural gas found in coal fields. Geologists use seismic surveys and find the right places to drill natural gases and oil wells.

Note: Oxygen will make confusion to the candidates. Oxygen is the most abundant element or gas in the atmosphere. But in natural gases, methane is the most abundant hydrocarbon.
