Answer:
Coal is classified as a nonrenewable energy source because it takes millions of years to form. Coal contains the energy stored by plants that lived hundreds of millions of years ago in swampy forests.
The answer to the question asked above is that in a Molecular Solid, the substance just dissolves into the solution when added to water but ionic solid does not.

The question is incomplete. complete question is;
A 0.10 mol sample of each of the four species in the reaction represented above is injected into a rigid, previously evacuated 1.0 L container. Which of the following species will have the highest concentration when the system reaches equilibrium?
a.
b.
c.
d.
Answer:
The correct answer is option a.
Explanation:
The equilibrium constant of the reaction=
Concentration of the species initially:
The equilibrium quotient of the reaction is :
(reaction will go backward)
Initially
0.10 M 0.10 M 0.10 M 0.10 M
At Equilibrium :
(0.10+2x) M (0.10+x) M (0.10-x) M (0.10-4x) M
Solving formx:
x = 0.099 M
As we can see that from the reaction at equilibrium, the concentration of hydrogen sulfide will be highest:
The Kelvin temperature K =℃ + 273.15. ℃ means centigrade temperature. So the centigrade temperature number between freezing point and boiling point is equal to the number of Kelvin. So the answer is 357-(-38)=395.
