Answer

Brief Explanations:

Oxygen and nitrogen are elements and carbon - dioxide is a compound. All are pure substances. Oxygen can react with many substances (e.g., combustion), nitrogen can also participate in certain reactions, and they are not chemically bonded in air. Only elements are single - type atoms, and carbon dioxide is a compound.

Answer:

Oxygen, nitrogen, and carbon dioxide are all classified as pure substances.
