The formula unit of compounds formed depends on the valency of the combining ions.
The formula unit is the smallest unit of an ionic substance that gives us a picture of the ratio in which ions are combined in the ionic compound.
Usually, the formula unit is written based on the valency of the ions.
For the ions listed;
Li+ and 02- forms Li2O
Mg2+ and S2- forms MgS
A13+ and CI- forms AlCl3
Na+ and N3- forms Na3N

Small bodies from which the planets are formed is called : Planetesimal.
Planetesimals that have survived to the current day are valuable to scientists since they contain information about the Solar System's formation.
Answer:
Acid solutions contain hydrogen ions. The higher the concentration of hydrogen ions, the lower the pH. Strong acids are fully ionised but weak acids are only partly ionised in solution.
Example:
Hydrochloric acid is a strong acid and ethanoic acid is a weak acid.
The climate is hot and humid because it rains everyday the average temperature is about 80 degrees farenheit
Answer:
The force of gravity between them would be doubled.
