The flux used in the smelting of copper ores is:
Correct answer: C. Silica
- A. Lime stone
- B. Magnesia
- C. Silica
- D. Coke
Explanation
In the smelting of copper ore SiO2 is used as a flux as it forms FeSiO2 as fusible slag. This slag helps in absorbing impurities and facilitating the separation of pure copper metal. The other options, like lime stone, magnesia, and coke, do not have the same chemical properties as silica to act as an effective flux in the smelting process of copper ores.

About s-Block and p-Block Elements
The s and p blocks are studied through their valence-shell configurations, periodic trends and characteristic chemical properties. Work covers the reactions of Group I and Group II elements, the behaviour of Group IV elements, and how atomic size, ionization energy, electronegativity and metallic character change across periods and down groups.
