Which reaction is practically not possible?
Correct answer: A. Be + 2H₂O → H₂ + Be(OH)₂
- A. Be + 2H₂O → H₂ + Be(OH)₂
- B. Mg + 2H₂O → H₂ + MgO
- C. Ca + 2H₂O → H₂ + Ca(OH)₂
- D. Ba + 2H₂O → H₂ + Ba(OH)₂
Explanation
Be + 2H₂O → H₂ + Be(OH)₂) - Correct: This reaction is not possible because Be does not react with water under normal conditions. Group IIA metals react with water to form hydroxides, except for beryllium, which does not react with water due to its high ionization energy and covalent nature

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.
