List the following compounds in decreasing electronegativity difference. cl2 hcl nacl

Chemistry

Mkey [24]3 years ago

Based on Pauling Scale, electro negativity of Cl = 3.2, Na = 0.9 and H = 2.1

Thus, Electronegativity difference  in Cl_{2} = 3.2 -3.2 = 0
Electronegativity difference  in NaCl = 3.2-0.9 = 2.3
Similarly, Electronegativity difference  in HCl = 3.2 - 2.1 = 1.1

Thus, among the listed molecules following is the decreasing order of electronegativity difference: NaCl> HCl > Cl_{2}

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 does lower case k stand for?
DaniilM [7]
Just for more clarification, lowercase k is the rate constant. Uppercase K is the equilibrium constant. You can actually use k to find K (equilibrium constant). K=k/k' This means that the equilibrium constant is the rate constant of the forward reaction divided by the rate constant of the reverse reaction

For metals, reactivity _____ as you go from _____ in a period.
ki77a [65]

Reactivity - Reactivity refers to how likely or vigorously an atom is to react with other substances. This is usually determined by how easily electrons can be removed (ionization energy) and how badly they want to take other atom's electrons (electronegativity) because it is the transfer/interaction of electrons that is the basis of chemical reactions.  

Metals  

Period - reactivity decreases as you go from left to right across a period.  

Group - reactivity increases as you go down a group  

Why? The farther to the left and down the periodic chart you go, the easier it is for electrons to be given or taken away, resulting in higher reactivity.  

Non-metals  

Period - reactivity increases as you go from the left to the right across a period.  

Group - reactivity decreases as you go down the group.  

Why? The farther right and up you go on the periodic table, the higher the electronegativity, resulting in a more vigorous exchange of electron
