Sulfur smells like rotten egg and is yellow...
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>
- Russia
- Iran
- 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 :
- <em>Tight Gas</em>
- <em>Shale Gas</em>
- <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.
False, kinetic energy depends on an objects mass and speed
|F| = 112 - 67 = 45 N
F = 45 N ( to the left)
C₀=2 mol/l
c₁=0.400 mol/l
v₁=100.0 ml = 0.1 l
c₁v₁=c₀v₀
v₀=c₁v₁/c₀
v(H₂O)=v₁-v₀
v₀=0.1*0.400/2=0.02 l = 20 ml
v(H₂O)=100 - 20 = 80 ml
It is necessary to mix 20 ml of the feed solution and 80 ml of water.
