• A mixture, such as A mixture, such as the pizza or soft the pizza or soft drink shown, is a drink shown, is a material made up material made up of two or more of two or more substances that can substances that can be easily separated be easily separated by physical means.by physical means.

Mixtures

Composition of MatterComposition of Matter

• A combination of two or more substances in which the basic identity of each substance is not changed.

Mixtures


Heterogeneous Mixtures


• A mixture in which A mixture in which different materials can be different materials can be distinguished easily is distinguished easily is called a called a heterogeneousheterogeneous (he tuh ruh JEE nee us)(he tuh ruh JEE nee us) mixture.

• 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


• For example, the cheese in pizza is also a mixture, but you cannot see the individual components.

Homogeneous Mixtures


• A A homogeneoushomogeneous (hoh muh (hoh muh JEE nee us)JEE nee us) mixturemixture contains contains two or more gaseous, liquid, two or more gaseous, liquid, or solid substances blended or solid substances blended evenly throughout.evenly throughout.

• Soft drinks contain water, sugar, flavoring, coloring, and carbon dioxide gas.



• Soft drinks in sealed bottles are examples of homogeneous mixtures.

• Another name for homogeneous mixtures like a cold soft drink is solution.



• 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.

•Materials are made of a pure substance or a mixture of substances.

Pure Substances


• 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.

Alloys 15.115.1

•Solid solutions that contain different metals and sometimes nonmetallic substances.

Gold Alloys - Pure gold is generally too soft to be used for jewelry, so other metals are nearly always added to it

Gold Alloys 15.115.1


Gold Karat Markings24K gold is pure gold. 18K gold contains 18 parts

gold and 6 parts of another metal(s), making it 75% gold.

Gold Alloys 15.115.1

Gold Karat Markings12K gold contains 12 parts

gold and 12 parts of another metal(s), making it 50% gold.

10K gold contains 10 parts gold and 14 parts another metal(s), making it 41.7% gold.

Alloys 15.115.1

White Gold AlloysNickel can be mixed with

gold to create a white (or gray) color; it can cause dermatitis in people who are sensitive to nickel.
