Question

The formula of the nitride of a metal A is XN. State the formula of [2]

(i) its carbonate (ii) its chloride (iii) its sulphate (iv) its hydroxide​

Answer 1

Answer:

(i) $A_{2} (CO_{3}) _{3}$

(ii) $ACl_{3}$

(iii) $A_{2}(SO_{4})_{3}$

(iv) $A OH_{3}$

Explanation:

As the nitride is $N^{3-}$

∴$A^{3-}$ also so that their formula does not contain a subscript

and then criss-crossing it with $CO^{2-}_{3}$, $Cl^{1-}$, $SO^{3-}_{4}$ and $OH^{1-}$ for deriving their formulae
