What conclusion can you draw from the heating curve?

A)
The absolute value of the heat of sublimation is equal to the absolute value of the heat of deposition.

B)
The heat of sublimation is equal to the sum of the heat of vaporization and the heat of freezing.

C)
The absolute value of the heat of deposition is equal to the sum of the absolute value of the heat of vaporization and the absolute value of the heat of freezing.

D)
The heat of sublimation is equal to the sum of the heat of vaporization and the heat of melting.

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

i just calculated it all out, and not including weekends, and all the different days off. as of this school year (2018-2019) students are spending 2198 hours in school this year

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
