Calculate the fraction of vacancies (Nv/N) given the following: Temperature 701 in kelvin, ΔHv=100kJ/mol, R=8.314J/mol. K. Use equation 4.3 from the textbook. Type answer in exponential form (e. g. 1.00e-11) round to two decimal points

The answer is 3.89x10^-8

Explanation:

The term vacant is used in crystallography to indicate a defect in a crystal. The crystals naturally have imperfections. A defect in which an atom is missing is called a vacancy defect, or Schottky's defect.

The temperature depends of the vacancy density, we have:

NV/N = A*e^-(ΔHv/R*T) = 1.1*e^(-100000/(8.314*701)) = 3.89x10^-8

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
