(II) Aluminium |
Let us break down the matching of each ore with its corresponding metal:
A. Calamine: Calamine is a zinc ore. It primarily consists of zinc carbonate \((ZnCO_3\) and is a significant source of zinc metal.
B. Malachite: Malachite is an ore of copper. It is a green carbonate mineral with the chemical formula \(Cu_2CO_3(OH)_2\) and is a major source of copper.
C. Siderite: Siderite is an iron ore. It is an iron carbonate mineral with the chemical formula \(FeCO_3\) and is an important source of iron.
D. Cryolite: Cryolite is an ore of aluminum. It is a mineral consisting of sodium aluminum fluoride, with the chemical formula \(Na_3AlF_6\). Cryolite was historically used as a flux in the production of aluminum.
Therefore, the correct match is:
(A) Calamine: Ore of Zinc (III)
(B) Malachite: Ore of Copper (I)
(C) Siderite: Ore of Iron (IV)
(D) Cryolite: Ore of Aluminium (II)
This arrangement aligns with the compositions and properties of each ore and the corresponding metal extracted from it.
