Is mixed green salad an element or compound mixture?

* Heterogeneous Mixture: A mixture where the components are not evenly distributed and can be easily separated. You can see the individual components (lettuce, spinach, etc.) in a mixed green salad.

Let's break down why it's not the other options:

* Element: A pure substance made up of only one type of atom (like oxygen or gold). A salad is made up of many different substances.

* Compound: A pure substance made up of two or more different elements chemically bonded together (like water - H2O). The ingredients in a salad are not chemically bonded.

Key takeaway: Because you can see the different parts of a mixed green salad and they are not chemically combined, it's classified as a heterogeneous mixture.
