The solubility product for an insoluble salt with the formula M2X3 is written as ________, where s is the molar solubility

Chemistry
1 answer:
masha68 [24]2 years ago

Answer:

36s^5

Explanation:

We have;

M2X3 (s)------> 2M^3+(aq)  + 3X^2-(aq)

If [M^3+(aq)] = [X^2-(aq)] = s

We then have;

Ksp = (2s)^2 * (3s)^3

Ksp = 4s^2 * 9s^3

Ksp = 36s^5

Note that Ksp is known as the solubility product. It is an equilibrum equation that shows the solubility of a solute in water.

The atomic number(Z) is equal to the number of protons to equal to number of electrons.

The number of neutrons is equal to atomic mass minus the atomic number

n=A-Z

For Zn^2+, Z=28, e=28

For iron, Z=25,A=55

The number of neutrons is 55-25=30

The charge is zero

For O^2-, Z=8+2=10, n=p=10

The number of neutrons is 16-10=6

For sulfur, Z=16,A=34

For S2-, Z=16+2=18, A=34

The charge is 2-

  • The atomic number is the basis of the periodic table.
  • It is equal to the number of protons.
  • The number of neutrons is atomic mass minus atomic number.

What does the atomic number tell you about the element
jonny [76]
It tells you how many protons it has and because the number of protons =electrons it tells you also the number of electrons.

You want to know how many moles of gas your lungs can hold. You start off with a balloon that has 1.4 moles of gas and occupies
Mrrafil [7]

Number of moles : n₂ = 1.775 moles

<h3>Further explanation</h3>

Given

Moles = n₁ = 1.4

Volume = V₁=22.4 L

V₂=28.4 L

Required

Moles-n₂

Solution

Avogadro's hypothesis, at the same temperature and pressure, the ratio of gas volume will be equal to the ratio of gas moles  

The ratio of gas volume will be equal to the ratio of gas moles

\tt \dfrac{V_1}{V_2}=\dfrac{n_1}{n_2}

Input the values :

n₂ = (V₂ x n₁)/V₁

n₂ = (28.4 x 1.4)/22.4

n₂ = 1.775 moles
