You would not guess that they contain shiny metal. The earth's crust is made up of many minerals. Minerals can be defined as naturally occuring chemical elements and compounds. People have discovered more than 2,000 different minerals. Many of these contain metals. But because the metal elements are linked with other elements in the minerals, the metals do not show all of their properties. Figure A 1. Most minerals are elements, compounds 2. In order to free the metal from the other elements, a mineral must be synthesized, decomposed Page 3 I 6 Q +

Antoine uses hls ideas to explain burning as the comblnation of a substance with oxygen, and reduction (e.g. durlng che formation of iron from iron ore) as the splitting of a substance from a chemical combination with oxygen. for chemical reactions based around the ohn analyzes all the known compounds of carbon and oxygen. He finds nd writes down a that says the ratio of masses of carbon that combine with 100 g of oxygen in these compounds are always in whole umber ratios (e.g. 2:1 or 3:1).
