Answer 2

Hii...

=> a) The more energy needed, the higher the melting point or boiling point . Since the electrostatic forces of attraction between oppositely charged ions are strong, their melting and boiling points are high.

b) The noble gases are the least reactive of all the elements but the heavier ones do form some molecules. Helium and neon never form molecules. They have completely filled electron shells with no have-filled orbitals available for making covalent bonds and they have very high ionization energies so they don't form ions.

c) The conductivity of dilute hydrochloric acid is greater than that of acetic acid. Acetic acid is weak electrolyte which dissociated partially whereas HCl is strong electrolyte which dissociates completely, therefore, HCl is better conductor compared to CH3COOH. 32.

d) Ionic compounds conduct electricity when molten (liquid) or in aqueous solution (dissolved in water), because their ions are free to move from place to place. Ionic compounds cannot conduct electricity when solid, as their ions are held in fixed positions and cannot move.

e) So, it's more accurate to say pure covalent compounds do not conduct electricity. Polar covalent compounds may be conductive when dissolved in water.
