Answer: Limestone is a sedimentary rock.
Explanation:
1. Limestone is a carbonate sedimentary rock made up of calcite(CaCO₃).This rock type forms calcareous shells and tests of organisms that was deposited in a sedimentary basin.
Limestone is used in building and construction works. It also finds application in chemical industries.
2. Over a long period of time, we would take a look at the rock "limestone" through the rock cycle.
Limestone being a sedimentary rock would be converted to marble, a metamorphic rock if subjected to metamorphic conditions over an extensive period of time. With series of metamorphic transformation, marble can grade to higher metamorphic facies of rocks as it combines with other minerals in the crust. The minerals would eventually change and as the changed rock approaches its melting temperature, melt would result.
From the other spectrum, limestone can be weathered if subjected extensively to denudation forces such as wind, water and glaciation. Water is more potent for the chemical weathering of limestone. Limestone would easily and readily dissolve in it over a long period of time.
Answer:
A nitrogen atom must gain three electrons to have the same number of electrons as an atom of the following noble gas, neon. Thus, a nitrogen atom will form an anion with three more electrons than protons and a charge of 3−. The symbol for the ion is N3−, and it is called a nitride ion.
Answer:
The total pressure in the container at equilibrium is 0.37065 atm
Explanation:
<u>Step 1: </u>Data given
Kp for the decomposition of H2S is 0.795
Only H2S is present at a pressure of 0.203 atm
<u>Step 2:</u> The balanced equation
H2S (g) → H2(g) + S(g)
<u>Step 3: </u>Calculate partial pressure of H2 and S
Initially, there is no H2 and S, they have no pressure
There will react X
The pressure at the equilibrium we have:
H2: X
S: X
H2S: 0.203 - X
Kp = (pH2)(pS)/(pH2S)
0.795 = (x)(x)/(0.203 - X)
X = 0.16765
<u>Step 4:</u> Calculate total pressure at equilibrium:
Total pressure = the partial pressure of H2 + partial pressure of S + partial pressure of H2S
P = X + X + (0.203 - X)
P = 0.16765 + 0.16765 + (0.203 - 0.16765)
P = 0.37065 atm
The total pressure in the container at equilibrium is 0.37065 atm
