"Reduce, reuse, recycle." Give examples of how one or more of
these ideas can be applied to the issues and practices of hydraulic
fracturing for the acquisition of shale gas.
Answer:
Examples of how the ideas can be applied to the issues and practices of hydraulic fracturing for the acquisition of shale gas are;
Reuse; The produced water in obtained from oil and gas well production are reused for fracking, drilling, and if the water is good enough, it can be used for farming
Reduce; The use of recycled brine and water in drilling and fracking process reduces the application of freshwater in the those processes and reduces pollution of natural water sources
Recycle; Recycling involves creating products from waste. In the hydraulic fracturing process approximately 13 percent of the water produced and the flowback water are recycled to be used more than once thereby reducing the net consumption of freshwater
Explanation:
In hydraulic fracturing, also known informally as fracking, is the drilling method used in oil and gas well development process that makes use of water sand and chemical injection through the well bore to open and widen cracks in the bedrock formations in the areas around the wellbore.

What is the concentration of a solution with a volume of .45 L that contains .9 moles of Iron (II) chloride?
Answer:
the concentration of the solution is 2 mol/L.
Explanation:
Molarity is defined as the concentration of a solution expressed in terms number of moles of solute per liter of solution.
Mathematically Molarity is expressed as follow;
[tex]Molarity = \frac{Moles \ of \ solute}{Liters \ of \ solution} \\\\[/tex]
Given;
Volume of the solution, V = 0.45 L
Moles of the solute, n = 0.9 moles
The concentration of the solution [tex]= \frac{0.9}{0.45} = 2 \ mol/L[/tex]
Therefore, the concentration of the solution is 2 mol/L.

A 2.25 mol sample of oxygen occupies 1.80 L at 25.0°C. What volume will
it occupy with 3.7 moles?
Answer:
2.96 L
Explanation:
We apply the Ideal Gases Law to determine this:
P . V = n . R . T
Firstly we need to know the pressure for the 2.25 moles
P . 1.80L = 2.25 mol . 0.082 L.atm/mol.K . 298K
(We convert T°C to T°K, 25°C + 273 = 298K)
P = (2.25 mol . 0.082 L.atm/mol.K . 298K) / 1.80L
P = 30.5 atm
So now, we apply the pressure value for the new conditions:
30.5 atm . V = 3.7 mol . 0.082 . 298K
V = (3.7 mol . 0.082 . 298K) / 30.5atm = 2.96 L
When are atoms considered stable?
when they have satisfied the law of conservation of mass naturally or through bonding to obtain
full valence shells
when they have satisfied the octet rule naturally or through bonding to obtain full valence shells
when their valence electrons have "fallen" back to ground state through bonding
Answer:
when they have satisfied the octet rule naturally or through bonding to obtain full valence shells
Explanation:
Generally, most atoms of an element are unstable because they have a void in their electron shell to fill, hence, they need to react with other elements to fulfil this task of octet.
Octet rule states that atoms of elements engage in reactions to form compounds so they can have eight (8) valence electrons in their shell. Noble gases e.g argon, neon etc. are elements that have naturally satisfied this octet rule by possession of 8 valence electrons in their shell. Other elements that do not have this naturally becomes reactive and enter bonding with other atoms to obtain full valence shells.
List the following elements from increasing electronegativity: boron, magnesium, calcium, chlorine, argon
Answer:
The list of elements from increasing electronegativity: Calcium < magnesium < chlorine < argon < boron.
Explanation:
In the periodic table if you move from left to right there would be an increase in the electronegativity of the elements. If you move from the bottom to the top of the groups in the periodic table the electronegativity increases and if u move to the bottom from down its decreases.
Calcium is in the 2nd group below magnesium so calcium is the least electronegative among given elements then magnesium and then chlorine as it is top of magnesium then argon, as it is right to the chlorine, and boron has the most electronegativity as it is above rest of the elements.
Can someone help me out with why is the outer core of Earth is important in you’re own words?! A mini paragraph plsss

What is the [OH-] in a solution that has a pH = 9.23? *
O 1.7x10^5
O 8.2x10^-9
1.7x10^--5 M.
Answer: 1.7x10^-5
Explanation:
pH + pOH = 14
14 - pH = pOH
14 - 9.23 = 4.77
pOH =4.77
[OH-] = 10^-pOH
= 10^-4.77
= 1.698243x10^-5
= 1.7x10^-5

What is the molarity of a solution which contains 0.80 mol of HCl in 250mL of
solution?
Answer:
3.2M HCl Solution
Explanation:
Molarity = moles of solute / volume of solution expressed in liters
moles of solute = 0.80 moles HCl
volume of solution = 250 ml = 0.250 Liter
Molarity (M) = 0.80 moles HCl / 0.250 Liters = 3.2M HCl Solution

What is the relationship between density and speed of light?
Answer:
The more optically dense that a material is, the slower that a wave will move through the material. ... So as the index of refraction value increases, the optical density increases, and the speed of light in that material decreases.
What is the initial reactant for a fusion reaction in the sun?
a) Iron-56
b) Hydrogen-1
Hydrogen
Pog Pog Pog I'm a PogChamp
Hydrogen-1 serves as the starting reactant in fusion reactions in the sun. This is due to the sun's composition, which is around 70% hydrogen and 28% helium with 2% heavier components. As a result, hydrogen-1 is both the most prevalent and most likely to be employed in a fusion process in the sun.
What is the way to make helium-4 ?Two hydrogen-1 nuclei are fused together to create a helium-4 nucleus in the sun's fusion reaction, which releases energy in the process. This is the most significant energy source in the sun and is known as the proton-proton chain reaction.
When two hydrogen-1 nuclei collide to generate a deuterium nucleus, a gamma ray is released as a result, starting the reaction. Then, this deuterium nucleus strikes another.A helium-3 nucleus is created from a hydrogen-1 nucleus, which also produces a gamma ray.
The reaction is finally finished when two helium-3 nuclei meet to produce a helium-4 nucleus, producing two gamma rays in the process. Since hydrogen-1 is the most prevalent element in the sun and the element that is most likely to be employed in the proton-proton chain reaction, it is the first reactant for a fusion process in the sun.
A deuterium nucleus is created by the collision of two hydrogen-1 nuclei, which is followed by a sequence of further processes that ultimately result in the development of a helium-4 nucleus.
