No, they are kept from combining by hydration spheres.
Polar molecules dissolve in water. The reason why polar molecules dissolve in water, but not non-polar molecules is because non-polar molecules can't form hydrogen bonds.
Polar molecules are mixed better with water.
Water attracts polar molecules and repels non-polar molecules because water has polar molecules. Water does have a net dipole though it doesn't have net charge.
Water is polar while oils are non-polar. Molecules that are polar will mix with other polar molecules, and non-polar molecules will mix with other non-polar molecules. Polar and non-polar molecules will not mix.
It dissolves all kinds of molecules. However, the ones that it dissoves well are molecules that it can hydrogen bond with or molecules that are polar that it can have dipole-dipole interactions with.
A water molecule is polar, which is why it attracts other polar molecules.
Hydrophobic molecules do not dissolve in water. This is because water is hydrophilic. Another way to say this is that lipids, which are nonpolar, cannot dissolve in water, which in polar.
Water molecules are polar molecules. Both of the bonds inside the molecule are polar bonds.
Because water is polar, and polar solvants will dissolve polar solutes. :)
Polar Molecules
Water molecules are uncharged and polar.
