Hematite and Adamite Formula

Hematite and Adamite Chemical Properties gives us information about the mineral's chemical composition. A mineral is basically composed of various elements in varied proportions. These elements define how the mineral will behave when exposed to different conditions. These chemical properties also depend on the way the mineral atoms are bound in the mineral's crystal structure. On the basis of crystallography of minerals a chemical formula is designed for better interpretation of its structure. Hematite and Adamite Formula are of two types chemical and empirical. Formula of Hematite is Fe2O3 and Adamite is Zn2(AsO4)(OH) . The molecular weight of Hematite is 159.69 and Adamite is 286.71. The Atomic Structure of Hematite properties of minerals gives us further information about a minerals atomic structure.
