Water and oil is a heterogeneous mixture. Oil can be separated from water via specific methods. That's why a combination of water and oil is heterogeneous.
Water and oil do not mix with each other. It is a mixture.
Yes, a heterogeneous mixture is one in which the components are not uniformly distributed, like oil and vinegar. An example of a heterogeneous mixture is oil and vinegar salad dressing. Another example is sand and water, where the sand particles do not dissolve in the water.
The oil-water mixture is not homogeneous.
Yes as The amount of emulsifier in the mixture of water and oil is increased the time taken for the oil and water to separate is increased.
A mixture of oil and water is a mixture, not an element. If by substance you mean not a pure substance (element or compound), then oil and water would be a substance (that is a mixture). If you mean oil and water separately, then oil is a mixture of hydrocarbons, and water is a compound (pure substance).
