Imagine you are looking at a bottle of salad dressing containing oil, vinegar, and water. Why are there two layers in the salad
Korvikt [17]

Answer:

Oil and vinegar separate because it is a suspension

Explanation:

When you let suspensions sit the particles begin to layer out, in the salad dressing the oil layers out on top of the vinegar. The two layers of oil and vinegar don't actually dissolve in each other. The layer with the lower density (oil) floats on top of the layer with a higher density (vinegar)
