Question

If the formula of the oxide of a metal M is M2O, then the formula of its chloride is
A) MCl2 B) MCl C) MCl3 D) MCl4

Answer 1

Heya

Since the metal oxide is M20 .Hence ,

the metal ion is M²+.

Thus, its chloride

M²+ + Cl- = Mcl2.

Answer 2

If the formula of the oxide of a metal M is M2O, then the formula of its chloride is

B) MCl :

Explanation:

• Oxygen ion is a a double negative Ion. As a result of this in the given problem metal m is a unit positive metal Ion. Hence the metal is an alkali metal. As a result of this since the valency of chlorine is equal to one hence it will form the compound MCl.

• this is similar to that of sodium which forms the compound Na2O and it reacts with chlorine to form sodium chloride having the chemical formula in NaCl.
