Is Italian salad dressing heterogeneous or homogeneous?

Here's why:

* Heterogeneous mixtures have components that are visibly separate and can be easily distinguished.

* Homogeneous mixtures have components that are evenly distributed and appear as a single substance.

Italian salad dressing typically contains ingredients like oil, vinegar, herbs, and spices. These ingredients do not mix completely and often separate into layers or have visible particles.

You can easily see the oil separating from the vinegar and herbs. This separation indicates that the mixture is not uniform throughout, making it a heterogeneous mixture.
