<u>Answer:</u> When oppositely charged species interact.
<u>Explanation:</u>
Ionic compound is defined as the compound which is formed by the complete transfer of electrons from one element to another element.
In these compounds, oppositely charged ions are attracted towards each other to form a compound.
<u>For Example:</u> NaCl is formed by the attraction of 
ions. So, same number of oppositely charges maintain electrical neutrality.
Electrical neutrality in a compound is achieved when atoms forming a compound have same number of opposite charges. Basically the charges on cation is balanced by the charges on anion.
The chemical symbol for sodium bicarbonate is NaHCO3. Its molar mass is 84 g/mol. In each of one mol of sodium bicarbonate their is one mole of carbon dioxide with the molar mass of 44 grams per mol. We determine the number of moles in 0.10 g of sodium bicarbonate.
n sodium bicarbonate = (0.10 g) / (84 grams / mol)
= 1.19 x 10-3 moles sodium bicarbonate
Therefore, there are also 1.19 x 10-3 moles of carbon dioxide.
I’m assuming your just writing the formula? If so

The law that states the volume and absolute temperature of a fixed quantity of gas are directly proportional under constant pressure conditions would be the Charles Law. It <span>is an experimental gas </span>law<span> that describes how gases tend to expand when heated. Hope this answers the question.</span>
