Question

oil and water placed in a jar will separate. even when shaken and mixed, the oil still separates from the water.
which best describes oil and water?
○ oil and water are highly soluble because they have separate chemical properties.
○ oil and water have a low solubility because they have separate chemical properties.
○ oil and water are highly soluble because they exert different pressures.
○ oil and water have a low solubility because they exert different pressures.

Explanation:

Oil is nonpolar while water is polar; their differing chemical properties lead to very low solubility in one another, causing them to separate even after mixing. The other options are incorrect: they are not highly soluble, and pressure is not the reason for their separation.

Answer:

Oil and water have a low solubility because they have separate chemical properties.
