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.

Which type of reaction?
polet [3.4K]
condensation polymerization, since a byproduct of the reaction is a single molecule of water (hence condensation of water)

addition polymerization is if you add the two polymers together like blocks and should have no byproducts

esterification is when you combine an organic acid with an alcohol. Since neither of the two polymers look like acids, you can rule this out.

never heard of saponification, Im an mechanical engineer not an organic chemist

How many cubic feet of air at standard conditions 1.00 atm are required to inflate a bicycle tote of .50 cu. Ft. To a pressure o
Alexeev081 [22]
As I am reading the problem, I see they gave you two pressures, one volume and they are asking for another volume. this should give you a hint that you need to use the following formula. 

P1V1= P2V2

P1= 1.00 atm
V1= 0.50 ft³
P2= 3.00 atm
V2= ?

Now we plug the values

(1.00 x 0.50)= (3.00 x V2)

V2= 0.17 ft³

If you start with 13 mole H2O and 50 grams of O2 what is the percent yield of H202 if 100 grams of H202 is actually made?
dmitriy555 [2]

Answer:

94.1 %

Explanation:

We firstly determine the equation:

2H₂O + O₂ →  2H₂O₂

2 moles of water react to 1 mol of oxygen in order to produce 2 moles of oxygen peroxide.

We convert the mass of oxygen to moles:50 g . 1mol /32g = 1.56 mol

Certainly oxygen is the limiting reactant.

2 moles of water react to 1 mol of oxygen.

13 moles of water may react to 13/2 = 6.5 moles. (And we only have 1.56)

As we determine the limiting reactant we continue to the products:

1 mol of O₂ can produce 2 moles of H₂O₂

Then 1.56 moles of O₂ will produce (1.56 . 2) = 3.125 moles

We convert the moles to mass: 3.125 mol . 34 g/mol= 106.25 g

That's the 100% yield or it can be called theoretical yield.

Percent yield = (Yield produced / Theoretical yield) . 100

(100g / 106.25 g) . 100 = 94.1 %
