Define natural gas, liquefied petroleum gas (lpg), and liquefied natural gas (lng). what three countries have most of the world’s natural gas reserves? what are the major advantages and disadvantages of using conventional natural gas as an energy resource? what are three sources of unconventional natural gas and what major problems are related to the use of these resources?

The answer is treated below.

Explanation:

Natural gas: Natural gas is not used in its pure form; it is processed and converted into cleaner fuel for consumption. It is a fossil fuel composed almost entirely of methane, but contain small amounts of other gases, including ethane, propane, pentane and butane. It is a combustible,  gaseous mixture of simple hydrocarbon compounds, usually found in deep  underground reservoirs formed by porous rock. Natural gas is mainly used as fuel for generating  heat  and electricity.

Liquefied petroleum gas (LPG): Liquefied Petroleum Gas is a byproduct of natural gas and oil extraction and crude oil refining . At room temperature,  liquefied petroleum gas is a colourless and odourless gas which consists generally of butane (C4H10) or propane (C3H8) or a mixture of both.

Liquefied natural gas (LNG): Is natural gas that has been liquefied for ease of transport or storage. It is refrigerated to a very low temperature (-162 Celsius). At this temperature it becomes an odourless, non-toxic liquid that can be safely transported over long distances.

Three countries that have most of the world’s natural gas reserves

Major advantages of using conventional natural gas as an energy resource:

Major disadvantages of using conventional natural gas as an energy resource:

Three sources of unconventional natural gas :

Major problems related to the use of Tight Gas

Major problems related to the use of Shale Gas

Major problems related to the use of Coalbed Methane

b) mutualism

hope this : )

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
