Which of the following is a correct equilibrium expression?
A.
`"K"_("eq") = (["KOH"]^4["O"_2]^3)/(["KO"_2]^4["H"_2"O"]^2)`
B.
`"K"_("eq") = (["H"_2"O"]^2)/(["O"_2]^3)`
C.
`"K"_("eq") = (["KO"_2]^4["H"_2"O"]^2)/(["KOH"]^4["O"_2]^3)`
D.
`"K"_("eq") = (["O"_2]^3)/(["H"_2"O"]^2)`

The explanation is embedded in the word document attached
Answer:
Keq= [KOH]^4 [O2]^3/[[KO2]^4
Explanation:
4KO2(s) + 2H2O(l) → 4KOH(s) + 3O2(g)
Looking at the equation, the correct equilibrium expression is shown in the answer. The equilibrium constant for a reaction is given by the active masses of species involved in the reaction. The relative molar coefficients of species are raised to the power of their molar concentrations to give the active mass of each specie. This active mass now goes into the equilibrium equation.
Water is not included in the equilibrium equation because, as a solvent, it is present in large excess.

Answer:
The arrangement of particles is least ordered is a > c > b > d
Explanation:
Given that,
The arrangement of particles is least ordered in a sample of NaCl.
We know that,
The least ordered arrangement are.
The form of state of particle in least ordered.
So, The least ordered arrangement will be
aqua > gas > liquid > solid
The arrangement of particles is least ordered in a sample of NaCl
Hence, The arrangement of particles is least ordered is a > c > b > d

There are eight hydrogen atoms in the following molecule of ammonium sulfide. Thus, the correct option for this question is C.
What is a Molecule?
A molecule may be defined as a cluster of atoms that are significantly bonded together in order to represent the smallest basic unit of a chemical compound that can involve in a chemical reaction.
According to this question, the correct representation of ammonium sulfide is , where the number of the hydrogen atoms is equal to 4 × 2 = 8. Apart from this, the number of nitrogen atoms is 2. While the number of sulfur atoms is only 1.
Therefore, there are eight hydrogen atoms in the following molecule of ammonium sulfide. Thus, the correct option for this question is C.
