Question

Italian dressing contains olive oil and vinegar, which will separate out from each other if left to sit. This makes the dressing a:
a. Heterogeneous mixture
b. Homogeneous mixture
c. both a and b
d. none

Italian dressing is considered a **heterogeneous mixture** because the oil and vinegar separate and can be distinctly seen as different layers when left to sit. A homogeneous mixture would have a uniform composition throughout, which is not the case here. Therefore, the correct answer is:

**a. Heterogeneous mixture**
