Answer:

Ion-dipole attraction and solvation of the ions

Step-by-step explanation:

Assume you have an ionic compound MX.

Ion-dipole interactions:

Water is a highly polar molecule.

The partially negative O atom is strongly attracted to the M⁺ cations at the surface of the solid. The partially positive H atoms are strongly attracted to the X⁻ ions.

If the water molecules hit the surface of the solid with the right orientation, the ion-dipole attractions will help dislodge the ions from the surface.

Solvation:

Once the ions are in solution, the ions are stabilized by solvation. The strong ion-dipole attractions cause a shell of water ions to form around the ionss.

The answer is "Option B"

Explanation:

From the query, the following knowledge is derived:

Yield in percentage = 47%

Performance of theory = 4860 g

Actual yield Rate =?

The percentage return is defined simply by the ratio between both the real return as well as the conceptual return multiplied by the 100. It's also represented as numerically:

$Rate = \frac{Existing \ Rate} {Theoretical \ Rate} \times 100$

Now We can obtain the percent yield as followed using the above formula:

$\text{Yield in percentage}= \frac{Actual \ yield \ Rate} {Theorical \ Rate} \times 100$

$47\% = \frac{Actual \ yield \ Rate}{4860}$

The value of the Actual yield Rate = $47\% \times 4860$

$= \frac{47}{100} \times 4860 \\\\ = 2284.2 g$

The Actual yield Rate= 2284.2 g.

1. Which graph shows the melting of crystalline solids? Explain your reasoning.

madreJ [45]

(1) The melting of a crystalline solid is best depicted by the second graph. This is because, the second graph shows a horizontal line which means that for a while there was no change in temperature. This zone is the latent heat of fusion.

(2) The first graph shows the graph of a solid that is just heated but does not experience phase change. However, the second graph shows a solid that changes phase (from crystal/solid to liquid).
