Question

the air we breathe contains different individual gases (mostly nitrogen and oxygen). which of the following correctly describes the air we breathe? compound liquid mixture element

Explanation:

A compound is a substance formed when two or more elements chemically bond together. A liquid is a state of matter with a definite volume but no definite shape. An element is a pure substance that cannot be broken down into simpler substances. A mixture is a combination of two or more substances that are not chemically bonded. Air is made up of different gases (nitrogen, oxygen, etc.) that are not chemically bonded, so it is a mixture.

Mixture
