Which of the following is a mixture? A. Blood B. Ice C. Oxygen D. Sodium

OpenStudy (anonymous):

A mixture is a combination of substances that are not combined chemically. Which of those match that description?

OpenStudy (anonymous):

idk

OpenStudy (anonymous):

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?

OpenStudy (anonymous):

so blood is a mixture

OpenStudy (anonymous):

You got it! Just remember that pure substances like elements and compounds are not mixtures until they are physically combined with other substances :)

oh ok thanks
