Question

this diagram represents a ______. mixture of compounds pure substance that is a compound mixture of elements pure substance that is an element

Explanation:

A mixture contains two or more different substances that are not chemically combined. Compounds are substances made up of two or more different elements chemically combined. Elements are pure substances made of only one type of atom. If the diagram shows different - looking particles not chemically bonded together, it is a mixture. Without seeing the actual diagram clearly, but if it shows different - looking particles, it is likely a mixture. If the particles are combinations of different atoms (compounds), it is a mixture of compounds.

Answer:

mixture of compounds
