Answer 2

The name and chemical composition of one important ore of aluminium is bauxite (gibbsite ($Al(OH)_{3}$), bohmite (AlOOH), and diaspore, AlO(OH)) and copper is chalcopyrite ($CuFeS_{2}$).

Explanation:

• An ore is defined as a solid substance which occurs naturally from a metal or when a valuable mineral can be profitably extracted.

• Bauxite is known as one of the important ore of aluminium. Chemical formula of aluminium is $Al_{2}O(OH)_{4}$. This ore of aluminium contains chemical composition as gibbsite ($Al(OH)_{3}$), bohmite (AlOOH), and diaspore, AlO(OH).

• On the other hand, one of the important ore of copper is chalcopyrite. Chemical formula of chalcopyrite is $CuFeS_{2}$. Chalcopyrite is brassy yellow in color with metallic luster, and high specific gravity.
