Answer 2

Answer:

Aerated water is carbon dioxide a pure substance or a mixture.

Explanation:

Aerated water is a carbon dioxide and water mixture that is homogeneous. It is not an entirely pure substance. Carbon dioxide is a compound, whereas oxygen and zinc are elements, or pure substances.

Aerated water is simply water that has had air added to it. However, the term is frequently applied to carbonated water. CO2 is a homogeneous gas. A substance must be chemically consistent throughout its parts in order to be homogeneous.
