Things that are denser than water will not dissolve Custard Powder Coco Powder.
flour doesn't dissolve in water because it is not dense enough
Proteins.
gases like CO2
While ionic compounds and polar molecules dissolve the best in water, nonpolar molecules do not. Example of a such nonpolar substance: oil. Oil forms clumps or beads in water because the nonpolar molescules are shoved together. Why? The water molecules are more attracted to each other than to the nonpolar molecules.
Lots and lots of things. It is said to be the universal solvent. It is very good at dissolving ionic compounds and most polar molecular compounds also. And, that is also one of the qualities that makes it so conducive to life. Water is not good a dissolving certain non-polar organic compounds because water if a very polar molecule and therefore is good at dissolving other polar molecules (remember, like dissolves like). However, oils and other non-polar compounds do not dissolve in water at all.
insoluble
Well...Magnesium sulfate actually does dissolve in water- you simply have to heat up the water.
Oil and sand are two substances that will not dissolve in water.
Oxygen does dissolve in water, how do you think aquatic animals survive without dissolved oxygen.

A substance that does not dissolve in water is said to be insoluble (in water). It should be noted that pepper is soluble in water.
using water displacement because it doesnt float on water and it doesnt dissolve in water
The reason why oil doesn't dissolve in ocean water is because oil is nonpolar and water is polar.
a solid that doesnt dissolve in water
no because organic compounds are compounds containing carbons and doesnt dissolve in water.
