Define natural gas, liquefied petroleum gas (LPG), and liquefied natural gas (LNG). What three countries have most of the world’
mrs_skeptik [129]

Answer:

The answer is treated below.

Explanation:

<u>Natural gas</u>: 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.

<u>Liquefied petroleum gas (LPG)</u>: 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.

<u>Liquefied natural gas (LNG)</u>: 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.

<u><em> Three countries that have most of the world’s natural gas reserves</em></u>

  1. Russia
  2. Iran
  3. Qatar

<em>Major advantages of using conventional natural gas as an energy resource:</em>

  • It is less expensive when compared to other fossil fuels.
  • It is safer and easier to store when compared to other fossil fuels

<em>Major disadvantages of using conventional natural gas as an energy resource:</em>

  • It costs more to recover the remaining natural gas because of flow, access, etc.
  • It is not a renewable source.
  • it is a combustible material, It must be handled with care.
  • It does not contribute to greenhouse gases.

Three sources of unconventional natural gas :

  1. <em>Tight Gas</em>
  2. <em>Shale Gas</em>
  3. <em>Coalbed Methane</em>

<u>Major problems related to the use of </u><u>Tight Gas</u>

  • When Hydrofluoric acid is used to release tight gas in reserves it potentially an issue simply because the substance is so dangerous. A spill or a leak could harm workers and pollute groundwater for uses.

<u>Major problems related to the use of </u><u>Shale Gas</u>

  • Risk of ground and surface water contamination.
  • Have impacts on air quality.

<u>Major problems related to the use of </u><u>Coalbed Methane</u>

  • The development of coalbed methane will result to soil disturbance from construction of wells, roads, and the associated pipeline and electric power rights-of-ways.
  • It has impact on wildlife.

What two types of matter are closest in<br> density? How do you know?<br> ings.
maks197457 [2]

Answer:

Density: The molecules of a liquid are packed relatively close together. Consequently, liquids are much denser than gases. The density of a liquid is typically about the same as the density of the solid state of the substance.

In a gas, the distance between molecules, whether monatomic or polyatomic, is very large compared with the size of the molecules; thus gases have a low density and are highly compressible. In contrast, the molecules in liquids are very close together, with essentially no empty space between them

I hope it helps you

What is the main function of messenger RNA?
Alla [95]
The right answer is C


Messenger RNA (mRNA) carries the genetic information copied from DNA in the form of a series of three-base code “words,” each of which specifies a particular amino acid. 2. Transfer RNA (tRNA) is the key to deciphering the code words in mRNA.
