It is 33.8.
Explanation:
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)`
Answer:
Answer is option D

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.
If the nucleus was the size of a tennis ball, the atom would be the size of a sphere about 1,450 feet in diameter.
The size of one atom would be comparable to one of the world's largest sports stadiums if the nucleus were the size of a tennis ball, or around 1,450 feet in circumference.
There are protons, neutrons, and electrons, three types of subatomic particles. Protons and electrons, two of the subatomic particles, each carry an electrical charge of one or the other.
Electrically charged protons and electrically neutral neutrons make up atomic nuclei. The strongest basic force known to science, often known as the strong force, holds these things together.

Answer:
The amount of energy release a reaction is depended on how strong the binding energy hold the particles together
In nuclear reaction, they're breaking nucleus bind apart , which create a huge amount energy that cause by the separation of the bind. The amount is far greater than in chemical reaction which only separate the binds of electrons.
