Write the chemical equation for the following reaction and balance the same by hit and trial method
Magnesium nitride + Water `rarr` Magnesium hydroxide + Ammonia.

Explanation

The skeleton equation for the reaction is :
`Mg_(3)N_(2)+H_(2)OrarrMg(OH)_(2)+NH_(3)`
The balancing is done in the following steps :
(i) Balance the Mg atoms
`Mg_(3)N_(2)+H_(2)Orarr3Mg(OH)_(2)+NH_(3)`

(ii) Balance the N atoms ltbgt `Mg_(3)N_(2)+H_(2)Orarr3Mh(OH)_(2)+2NH_(3)`
`Mg_(3)N_(2)+6H_(2)Orarr3Mg(OH)_(2)+2NH_(3)`
Upon checking, the H atoms are already balanced
`:.` Final balanced chemical equation is :
`Mg_(3)N_(2)+6H_(2)Orarr3Mg(OH)_(2)+2NH_(3)`.
