Answer:
Water is polar and oil is nonpolar so the substances won't mix.
Explanation:
Water is polar covalently bonded within the molecule. This unequal sharing of the electrons results in a slightly positive and a slightly negative side of the molecule. oils are nonpolar, so they will remain separate from molecules of a polar solvent such as water.
