Oil floating on water is not a "change", so asking whether it's a physical change or a chemical one is nonsense.
To the extent there's any meaning at all to the question, it's a phenomenon caused by the physical properties of the two materials.
It is a physical change because the oil and the water do not change in chemical composition.
your mixing two chemicals together so of course its a chemical change
chemical change. the dressing and mayonnaise changed completely to form the sauce.
No, it is not a chemical reaction. Chemical reactions occur when one or more chemical compound reacts to give one or more different chemical compounds. When oil and water are mixed, they can be separated to give the original amounts of oil and water without any new chemical compounds <==============================================3
Oil and water do not mix because they have different polarities. When oil and water are mixed, they separate into distinct layers due to their different densities. This separation is a physical change where the molecules of each substance retain their original properties.

When oil and water mix it is due to an emulsifier being added to the solution. The emulsifier has one hydrophobic tail which will attach to the oil and one hydrophilic tail which attaches to the water. It is more of a chemical change than a physical one since the oil and water don't change state, however they will not form an emulsification without an aid so its technically not due to a chemical reaction between the water and oil alone either.
physical- there's no chemical change.

No, it is a physical process.

Mixing oil and water is a physical change because no new substances are formed. The molecules of oil and water remain the same, they are just physically mixed together.
its not a chemical change because you can take the oil in
very bad! change the oil

Water does not mix with oil because oil is hydrophobic and water is hydrophilic. Mixing water with oil will result in the water forming droplets or a separate layer due to their different chemical properties.
