Is salad dressing an element a compound homogeneous mixture or heterogeneous mixture?

* Elements are pure substances made up of only one type of atom (like oxygen or gold). Salad dressing has many different ingredients.

* Compounds are formed when two or more elements chemically combine in a fixed ratio (like water, H₂O). Salad dressing doesn't have a fixed chemical formula.

* Homogeneous mixtures have a uniform composition throughout (like saltwater). Salad dressing often has visible parts, like oil and vinegar, that separate.

* Heterogeneous mixtures have components that are not evenly distributed. The ingredients in salad dressing can be easily identified and separated, meaning it's a heterogeneous mixture.
