<u>larger is the value of </u>Ksp<u> the higher will the solubility of solid in water.</u>

What is called compound?

  • In chemistry, a compound is a substance made up of two or more different chemical elements combined in a fixed ratio.
  • When the elements come together, they react with each other and form chemical bonds that are difficult to break.
  • These bonds form as a result of sharing or exchanging electrons between atoms.

The equation for the dissociation of a solid MX in water is given below

MX(s) ⇄ Mⁿ⁺(aq) + Xⁿ⁻ (aq)

Assume s be the solubility of MX in pure water, then the equilibrium concentrations of ions are

[ Mⁿ⁺] = s

[ Xⁿ⁻ ] = s

The expression for the solubility product constant (Ksp) is as follows

Ksp = [ Mⁿ⁺] [ Xⁿ⁻ ]

       = s²

That is, larger is the value of Ksp the higher will the solubility of solid in water.

Calculate the number of moles of iodine in 7.68×10^25 molecules of I2
Dmitrij [34]

Answer:

<h2>127.57 moles</h2>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

n =  \frac{N}{L} \\

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

n =  \frac{7.68 \times  {10}^{25} }{6.02 \times  {10}^{23} }   \\  = 127.574750...

We have the final answer as

<h3>127.57 moles</h3>

Hope this helps you

A 38.6 kg marble slab is shown above. What is its density? Give your answer to the nearest tenth.
LuckyWell [14K]

Answer:

Density, d=26.7\ g/cm^3

Explanation:

The attached figure shows a 38.6 kg marble slab. The dimensions of the marble slab is 23 cm × 17 cm × 4 cm

Density = mass/volume

Volume of a cuboid shape is equal to, V = 23 cm × 17 cm × 4 cm

V = 1564 cm³

Density,

d=\dfrac{38.6\times 10^3\ g}{1564\ cm^3}\\\\d=24.68\ g/cm^3

or

d=26.7\ g/cm^3

So, the density of the marble slab is 26.7\ g/cm^3.
