The correct answer is D. Distilled water.
A mixture is a material made up of two or more substances that are not chemically combined. The substances in a mixture can be elements, compounds, or other mixtures. Air is a mixture of gases, including nitrogen, oxygen, argon, carbon dioxide, and water vapor. Gasoline is a mixture of hydrocarbons, which are compounds made up of hydrogen and carbon atoms. LPG is a mixture of propane and butane, which are both hydrocarbons. Distilled water is a mixture of water molecules.
Distilled water is not a mixture because it is a pure substance. A pure substance is a substance that is made up of only one type of atom or molecule. Distilled water is made up of only water molecules. It does not contain any other substances, such as minerals or impurities.
Air, gasoline, and LPG are all mixtures because they are made up of two or more substances. Air is made up of nitrogen, oxygen,
argon, carbon dioxide, and water vapor. Gasoline is made up of hydrocarbons. LPG is made up of propane and butane.I hope this helps!
