Answer 1

The choice that best compares air and water is:

Air is a mixture of two or more components that keep their own identifying properties, while water is composed of elements that combine forming a compound.

This statement accurately reflects that air is a mixture (primarily of gases like nitrogen, oxygen, and other trace gases) where the components retain their individual properties, and that water is a compound formed from hydrogen and oxygen that has distinct properties different from its constituent elements.
