The common ion effect is the decreased solubility of the ionic precipitate in the solution. To promote the precipitation of the calcium sulfate, magnesium sulfate must be added.

<h3>What is the common ion effect?</h3>

It is a phenomenon that is due to the addition of the common ion already present in the solution that affects the equilibrium and is used to decrease the solubility of the solute present in the solution to increase the precipitation rate.

Magnesium sulfate will be added to the solution as it already contains the sulfate ion in the form of calcium sulfate. This will increase the precipitation of the compound as the common ion added will decrease the solubility.

Therefore, magnesium sulfate will be added to promote precipitation.

A researcher accidentally spilled some sand into his beaker containing crystalline compound X. Knowing what he did about melting
skad [1K]

Answer:

See explanation

Explanation:

If we look at the structure of X, we will discover that X is an organic compound. The compound will certainly have a much lower melting point than sand.

This is because, sand is composed of high melting point inorganic materials.

Hence, even though the researcher accidentally spilled some sand into the the beaker containing the crystalline substance X, he does not need to be perturbed since the melting point of X is much lower than that of sand

Mila [183]

Answer:

0.47m²

Explanation:

Given parameters:

Length = 9.025 x 10⁶m

Width  = 5.215 x 10⁻⁸m

Unknown:

Area of the rectangle  = ?

Solution:

Area is the derived from the product of the length and width of a body.

 Area  = length x width  = 9.025 x 10⁶m  x  5.215 x 10⁻⁸m

  Area  = 0.47m²
