A mixture is a combination of substances that are not combined chemically. Which of those match that description?
OpenStudy (anonymous):
idk

Well, Oxygen and Sodium are both pure elements. Ice is solid H20, which is a compound, or chemically combined elements. Blood is made up of oxygen, nutrients, plasma, and much more. Does this help?
