The actual reason for why water (H2O) and oil don't mix involves the charges or polarity of the two molecules. Remember the phrase, "like dissolves like." Think of oil as an uncharged molecule, and water as a slightly charged molecule. You can figure out why oil and water don't mix well by recognizing that the molecules are unlike, and following the "like dissolves like" idea.

the reason they're not mixed is Intermolecular bonds when water molecules have strong bonds with one another, called "hydrogen bonds." while Oil molecules also have very strong bonds with one
another, but not hydrogen bonds. Oil molecules are bonded to one another by what are called "London forces," or sometimes
"dispersion forces."
but you know what, at first I thought b/c the oil is lighter than water so oil float on water but not mix ^^ how silly I am

cause the liquid that is less dense will float on top of the denser liquid. It happens with any liquids not just oil & water. In this case since water weighs more than oil, this last one will float on top of the water. In this case we will need to make an emoulsion to make them combine.

It's chemistry!
Oil is a nonpolar substance with covalent bonds. Oil is a covalent network substance with weak intermolecular forces.
Water is a polar substance with strong hydrogen bonds. The weak forces in oil cannot overcome water because it has covalent bonds and cannot possibly form dipole-dipole bonds with water because it is nonpolar (symmetrical Lewis structure). Anything that dissolves in water is polar...anything that doesn't is non-polar.

The molecules of oil and water are non-polar, and polar, respectively. Water molecules have 2 ends, one positive, and one negative. Polar molecules attract other polar molecules, such as water, which is why they don't mix.

Oil and water have completly different elements and densitys, therefore they won't mix. Different desitys do not mix. Its physically Impossible.

no oil is liter than water

because oil floats.
