Answer:

<u><em>Compost</em></u> is a mixture dead organic material that can be used as fertilizer

Explanation:

Compost is a natural organic fertilizer that is prepared with different organic materials, providing nutrients and improving soil structure. Compost converts waste into fertilizer and valuable organic matter for soils.

The transformation of organic matter is carried out with composting, that is, the controlled decomposition of organic materials. Among them are fruits, pruning remains, vegetables, among others. The result of this procedure is a completely organic product that improves the soil structure and provides the necessary nutrients to the soil, all naturally.

Compost has a wide variety of advantages. Among them, it can be mentioned that urban waste is reduced considerably because it minimizes environmental problems related to its treatment and transportation. The soil structure will also be improved, helping with water retention, ventilation and the possible effects of frost. And the earth will eventually contain more organic matter and more nutrients; and it is possible to avoid the use of chemical fertilizers that can negatively affect the soil or the health of people. In addition, the lack of these substances produces an increase in the amount of microorganisms beneficial to the life cycle. Earthworms and other organisms will aerate the earth, prevent it from composting and favor the roots of plants.

So, <u><em>"compost is a mixture dead organic material that can be used as fertilizer"</em></u>

A saturated solution of Al(OH)3 has a molar solubility of2.9x J0-9 Mat a certain temperature. What is the solubility product con
Viktor [21]

The solubility product constant, Ksp, of the aluminum hydroxide, Al(OH)₃ at the temperature is 1.91×10¯³⁹

<h3>What is solubility of product? </h3>

The solubility of product (Ksp) is defined as the concentration of products raised to their coefficient coefficients. This is illustrated below:

mA <=> nC + eD

Ksp = [C]^n × [D]^e

With the above information in mind, we can obtain the solubility of the product. This is illustrated below:

<h3>Dissociation equation </h3>

Al(OH)₃(aq) → Al³⁺(aq) + 3OH¯(aq)

From the balanced equation above,

1 mole of Al(OH)₃ contains 1 mole of Al³⁺ and 3 moles of OH¯

<h3>How to determine the concentration of Al³⁺ and OH¯</h3>

From the balanced equation above,

1 mole of Al(OH)₃ contains 1 mole of Al³⁺ and 3 moles of OH¯

Therefore,

2.9×10¯⁹ M Al(OH)₃ will also contain

  • 1 × 2.9×10¯⁹ = 2.9×10¯⁹ M Al³⁺
  • 3 × 2.9×10¯⁹ = 8.7×10¯⁹ M  OH¯

<h3>How to determine the solubility of product </h3>

Concentration of Al³⁺ = 2.9×10¯⁹ M

Concentration of OH¯ = 8.7×10¯⁹ M

Solubility product (Ksp) =?

Al(OH)₃(aq) → Al³⁺(aq) + 3OH¯(aq)

Ksp = [Al³⁺] × [OH¯]³

Ksp = 2.9×10¯⁹ × (8.7×10¯⁹)³

Ksp = 1.91×10¯³⁹
