Question

Which constituent of natural gas takes the highest percentage in composition with the natural gas?
A.Methane
B.Ethane
C.Propane
D.Butane

Answer 1

Hint: Natural gas is a naturally occurring fuel source which is primarily composed of methane. Methane acts as better fuel as compared to other hydrocarbon or fossil fuels. It also produces significantly less carbon dioxide and other pollutant

Complete answer:
 Natural gas was discovered in China around 1000 BC. It is colorless and highly flammable. Due to its efficiency natural gas is commonly used as a fuel. But it has its own disadvantages. Use of natural gas emits carbon dioxide in the atmosphere. Natural gas is also used
1.Raw material to produce chemical
2.Production of fertilizers
3.Production of hydrogen
4.As an antifreeze
5.Production of ethane and propane
6.Generate electricity
Natural gas is a non renewable source of energy. Natural gas deposits are found near oil deposits. Natural gas is commonly extracted by drilling. Natural gas needs to be processed before it can be used.
Natural gas is a mixture of gases like methane, ethane, other higher alkane and some other gases like nitrogen, hydrogen sulfide and carbon dioxide. It is found naturally beneath the surface of earth. The chemical composition of natural gas
Methane \[60-90\%\]
Ethane \[0-20\%\]
Propane \[0-20\%\]
Butane \[0-20\%\]
Carbon dioxide \[0-8\%\]
Oxygen \[0-0.2\%\]
Nitrogen \[0-5\%\]
Hydrogen Sulfide \[0-5\%\]

So, the correct option is A.

Note:
The composition of natural gas can vary from place to place and purpose to purpose. But almost everywhere methane is the main component of natural gas, comprising at least 60% of the total mixture.
