Perhaps you have heard of something called the solubility rules. A great assist in predicting if a compound is soluble in water or not.
MgS - insoluble
CaCO3 - insoluble
Mg(OH)2 - insoluble
KCl - soluble

Magnesium sulfide, calcium carbonate, and magnesium hydroxide are insoluble in water.
Any ionic compound containing the sulfide ion (exceptions: compounds of ammonium ion, alkali metal cations, calcium, strontium, and barium ions), the carbonate ion (exceptions: compounds containing ammonium ion and alkali metal cations), the phosphate ion (exceptions: compounds containing ammonium ion and the alkali metal cations), and the hydroxide ion (exceptions: compound containing ammonium ion, calcium, strontium, and barium ions as well as alkali metal cations) is insoluble in water.
Note: exceptions make the compound soluble.

Mg(OH) is the only one insoluble
