Question

MCO3 is the carbonate of a metal 'M'. Write down the formula of its a) chloride b) nitride

Answer 1

Explanation:

cl and ni ok

ANSWER

In compound M

2

CO

3

, the valency of metal is +1.

Therefore, the formula of metal iodide is MI and for metal phosphate is M

3

PO

3

.

The formula of metal nitride will be M

3

N.

Answer 2

The formula of the chloride and the nitride of metal 'M' whose carbonate is MCO3 is MCl₂ and M₃N₂ respectively.

• It is given that MCO3 is the carbonate of a metal 'M', the valency of carbonate is -2. This implies that the metal 'M' has the valency of +2.
• To verify that the valency of metal 'M' is +2, we will find the formula of its carbonate:

                           M            CO₃

                            +2            -2

The carbonate of metal 'M' is MCO3 which is already given, so the valency of 'M' is +2.

• The formula of Chloride is MCl₂
• The formula of Nitride is M₃N₂.

Hence, the formula of the chloride and the nitride of metal 'M' whose carbonate is MCO3 is MCl₂ and M₃N₂ respectively.
