Mixtures Composition of Matter

10. A combination of two or more substances in which the basic identity of each substance is not changed. Mixtures Composition of Matter

11. Heterogeneous Mixtures Composition of Matter A mixture in which different materials can be distinguished easily is called a heterogeneous (he tuh ruh JEE nee us)A mixture in which different materials can be distinguished easily is called a heterogeneous (he tuh ruh JEE nee us) mixture.

12. Most of the substances you come in contact with every day are heterogeneous mixtures. Some components are easy to see, like the ingredients in pizza, but others are not. Heterogeneous Mixtures Composition of Matter For example, the cheese in pizza is also a mixture, but you cannot see the individual components.

Homogeneous Mixtures Composition of Matter A homogeneous (hoh muh JEE nee us) mixture contains two or more gaseous, liquid, or solid substances blended evenly throughout.A homogeneous (hoh muh JEE nee us) mixture contains two or more gaseous, liquid, or solid substances blended evenly throughout.

14. Soft drinks contain water, sugar, flavoring, coloring, and carbon dioxide gas. Homogeneous Mixtures Composition of Matter Soft drinks in sealed bottles are examples of homogeneous mixtures.

15. Another name for homogeneous mixtures like a cold soft drink is solution. Homogeneous Mixtures Composition of Matter A solution is a homogeneous mixture of particles so small that they cannot be seen with a microscope and will never settle to the bottom of their container.

16. Materials are made of a pure substance or a mixture of substances. Pure Substances Composition of Matter

17. A pure substance, or simply a substance, is a type of matter with a fixed composition. A substance can be either an element or a compound.
