Question

Write name, Molecular formula of the common ore of aluminum.

Answer 1

We need to find out the most common ore of aluminum and accordingly write its molecular formula. Ore is natural rock or silt that contains one or more precious minerals, usually metals, and may be mined, processed, and sold for a profit. Aluminum is the most plentiful metal element in the Earth's crust, and its ore is mined.

Complete answer:
The world's major supply of aluminium is bauxite ore. To create alumina, the ore must first be chemically treated (aluminum oxide). The alumina is then melted by electrolysis to generate pure aluminium metal. Bauxite is commonly found in topsoil in tropical and subtropical climates. The ore is mined in an ecologically friendly manner using strip mining. Bauxite is a sedimentary rock that has a significant amount of aluminium. It is the primary source of aluminium and gallium in the world. Carl Josef Bayer invented the Bayer process, which is the primary industrial method of processing bauxite to generate alumina (aluminium oxide). Bauxite, the most significant resource of aluminium, comprises only $30 - 60\%$ aluminium oxide ($A{l_2}{O_3}$), with the remainder consisting of silica, different iron oxides, and titanium dioxide. Before it can be processed into aluminium metal, aluminium oxide must be purified.
The common ore of aluminium is Bauxite whose molecular formula is ${A{l_2}}{H_2}{O_4}$

Note:
It must be noted that Bauxite is primarily composed of the minerals asuyhinitte, boehmite, and diaspore, as well as the iron oxides goethite and haematite, the aluminium clay mineral kaolinite, and trace quantities of anatase and ilmenite. Bauxite has a dull shine and is either reddish-brown, white, or tan in appearance.
