How is the concept of heat related to the kinetic molecular theory and the law of conservation of energy?

The first law states that the total increase in the energy of a system is equal to the increase in thermal energy, meaning that heat is a form of energy and is therefore subject to the the principle of conservation

Calculate the molar solubility of CaF2 at 25°C in a solution that is 0.010 M in Ca(NO3)2. The Ksp for CaF2 is 3.9 x 10-11.
madreJ [45]

Answer:

Molar \ solubility=3.12x10^{-5}M

Explanation:

Hello,

In this case, for the dissociation of calcium fluoride:

CaF_2(s)\rightleftharpoons Ca^{2+}+2F^-

The equilibrium expression is:

Ksp=[Ca^{2+}][F^-]^2

In such a way, via the ICE procedure, including an initial concentration of calcium of 0.01 M (due to the calcium nitrate solution), the reaction extent x is computed as follows:

3.9x10^{-11}=(0.01+x)(2*x)^2\\\\x=0.0000312M

Thus, the molar solubility equals the reaction extent x, therefore:

Molar \ solubility=3.12x10^{-5}M

Regards.

How could you tell whether a liquid is <br> honey or vinegar?
MissTica
Based on the liquids viscosity (which is a measure of how quickly/slowly a fluid can flow).

Higher viscosity represents a "thicker" liquid & slower flow (honey)
Lower viscosity represents a "thinner" liquid & quicker flow (vinegar)

The osmotic pressure exerted by a solution is equal to the molarity multiplied by the absolute temperature and the gas constant
zavuch27 [327]

Answer: M = 22/ (i x28.948)

Explanation:

Pi = osmotic pressure = 22atm

T = Temperature = 353K

M = Molarity = ?

R = gas constant = 0.082atm.L/mol/K

i = van’t Hoff factor

Pi = iMRT

M= Pi /(iRT) = 22 / ( i x 0.082 x 353)

M = 22/ (i x28.948)

What is the relationship between the surface of an object and the amount of friction it produces?
bearhunter [10]

Friction is the resistance to motion of one object moving relative to another. It is not a fundamental force, like gravity or electromagnetism. Instead, scientists believe it is the result of the electromagnetic attraction between charged particles in two touching surfaces.
