What kind of mixture consists of two or more phases, exemplified when a combination of oil and water forms layers?
- Correct Answer: heterogeneous
- complex miture
- homogeneous

Explanation: A phase is any part of a sample that has a uniform composition and properties. By definition, a pure substance or a homogeneous mixture consists of a single phase. A heterogeneous mixture consists of two or more phases. When oil and water are combined, they do not mix evenly, but instead form two separate layers. Each of the layers is called a phase.
