It is known as fracking and it uses pressurized liquids to fracture rock formations that hinder access to natural gas. What is it?.
Hydraulic fracturing is known as fracking and it uses pressurized liquids to fracture rock formations that hinder access to natural gas.
Hydraulic fracturing, or “fracking” as it's miles extra commonly known, is simply one small approach of the broader technique of unconventional development of oil and herbal fuel. Fracking is a proven drilling era used for extracting oil, natural fuel, geothermal electricity, or water from deep underground.
Fracking is brief for hydraulic fracturing, which is the manner of making fractures in rocks and rock formations by means of injecting specialized fluid into cracks to pressure them to open similarly. the larger fissures permit greater oil and gas to drift out of the formations and into the wellbore.
Hydraulic fracturing is used to grow the charge at which materials such as petroleum or natural fuel may be recovered from subterranean herbal reservoirs. Reservoirs are normally porous sandstones, limestones or dolomite rocks, but also encompass "unconventional reservoirs" which include shale rock or coal beds.

Based on location in the periodic table, which element has chemical properties that are most similar to iodine (i)?.
Fluorine (F) is an element that has the most similar chemical properties to iodine based on location in the periodic table.
Halogen elementsThe halogen elements, namely fluorine, chlorine, bromine, and iodine, are elements of the halogen or VIIA group in the periodic table of elements. These elements have ns2 np5 valence electrons. The reactivity of a substance is related to the ease with which the outer electrons of an element's atom can be released (metals) or captured (non-metals). Since the group VIIA elements are non-metallic elements that tend to gain electrons, their reactivity is directly proportional to their electron affinity. The greater the electron affinity, the easier it is for the atom to react (capture 1 electron). Because in a group of halogen elements the electron affinity decreases from top to bottom, so the topmost element, fluorine, is the element with the greatest electron affinity. This means that the fluorine element is the most reactive among the halogen elements.

isomorphous substitution results in a permanent charge on soil clay minerals. group of answer choices true false
Isomorphous substitution results in a permanent charge on soil clay minerals are False.
The process of replacing one structural cation with another of similar size is called isotypic replacement. This substitution is the main source of both the negative and positive charges in clay minerals. The importance of isomorphic substitution is to create a net negative charge on the clay. It must be balanced by ions.
Soil colloidal charge arises mainly from three sources. Due to the isomorphic substitution of one ion for another ion of a different valence within the clay mineral structure. This creates a predominantly negative charge. The charge is permanent and does not change with changes in the pH of the external solution. The effect of isomorphic substitution in clay minerals is to impart a negative charge to the particles.

i) The initial volume of the gas is 4.6 L
ii) The temperature of the gas is 212.7 K
What is the initial volume?We know that work can be done by a gas when the gas expands because the gas is pushing against the walls of the container and as such we have the use of the formula;
W = PΔV
W = work done
P = pressure of the gas
V = volume of the gas
Now;
The work done is 3000 J or 29.6 Latm
29.6 = 1(25 - V1)
V1 = initial volume
29.6 = 25 - V1
V1 = 29.6 - 25
V1 = 4.6 L
Now we have to obtain the temperature of the gas during the cause of the isothermal expansion of the gas as follows;
W =nRTln(V2/V1)
n = Number of moles
R = gas constant
T = temperature
3000 = 1 * 8.314 * T ln(25/4.6)

What happened when the ball was pulled toward the center of gravity?
When the ball was pulled toward the center of gravity is the gravity pulls the ball towards the center of the earth.
The gravity pull the ball towards the center of gravity is due the gravitation force by earth acted on ball. the center of gravity is the point of ball where the weight is distributed in all direction. The center of gravity of uniform ball is at the geometrical centre. if we through a ball in upward direction , the force of gravity pull the ball in downward direction . The force of gravity is directly proportional l to the mass of two objects and inversely proportional to the distance between them.
Thus, When the ball was pulled toward the center of gravity is the gravity pulls the ball towards the center of the earth.

write a balanced equation for the reaction of thiosulfate (s2o32-) and permanganate (mno4-) ions in acidic solution to form sulfate and manganese(ii) ions.
When potassium permanganate is reacted with thiosulfate, then there is formation of potassium sulfate and magnese ion.
What is potassium permanganate?The inorganic substance potassium permanganate has the formula KMnO₄. It is a crystalline salt that is purple-black and dissolves in water into a solution of K+ and MnO₄.
As a potent oxidizing agent, dermatitis medicine, wound cleaner, and general disinfectant, potassium permanganate is widely employed in the chemical industry and labs.
A balanced equation for the reaction of thiosulfate permanganate ions in acidic solution to form sulfate and manganese (ii) ions is
KMno₄ + Na₂S₂o₃ + H₂O ⇒ K₂So₄ + KOH + MnO₂ + Na₂So₄
Thus, the equation is KMno₄ + Na₂S₂o₃ + H₂O ⇒ K₂So₄ + KOH + MnO₂ + Na₂So₄.
