Answer:
D
Explanation:
The unit used to measure atomic mass is the atomic mass unit (amu). A single amu is equivalent to 1/12 the mass of an atom from the carbon-12 isotopIsotopes with different numbers of protons and neutrons will have an actual mass slightly different from the atomic mass calculated in atomic mass units.

From the calcuation, the percent ionic character of the bond is 70%
<h3>What is percent ionic character?</h3>
The term percent ionic character has to do with the degree of ionic bonding that is contained in a compound. It can be estimated from the electronegativity of each element.
We can use the formula; 100(1 - e^(-ΔEN² / 4))
EN = χB − χA * 100/1
EN = 3.5 - 1.5 = 1
100(1 - e^(-1)^2/4)
= 70%

Answer:
Explanation:
Dissolving is when a soluble solute is added to a solvent. The solvent surrounds the solutes and makes a solution of it. The process of dissolving is known as dissolution. For a substance to be able to dissolve in a solvent, they must both have similar properties. It is generally known that like dissolves like. Polar solvents will dissolve polar solutes and vice versa.
Boiling can reverse dissolution process in that, the solvent can reach its boiling point and it wil begin to give out vapours. As more vapours are release, the solutes begin to aggregate and form back.
