Formula of Felspar is :
Correct answer: A. K2O. Al2O3. 6 SiO2
- A. K2O. Al2O3. 6 SiO2
- B. K2O3. Al2O3.6Si2.O2.2H2O
- C. Al2O3. 2SiO2.2H2O
- D. 3MgO.4SiO2.H2O
Explanation
The correct formula for feldspar is K2O.Al2O3.6SiO2. Feldspar is primarily composed of aluminum silicates with potassium oxide and silicon dioxide. This combination distinguishes it from the other options provided, which contain different elements that are not part of feldspar's chemical composition.

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.
