When hydrated `MgCI_(2).6H_(2)O` is strongly heated,

Options

A. `MgO`
B. `Mg(OH)_(2)`
C. `Mg(OH)Cl`
D. `MgCl_(2)`

Answer

1

Explanation

`Ca(NH)+2H_(2)OrarrCa(OH)_(2)+underset((B))(NH_(3)(g))`
`underset((B))(2NH_(3))+3CaOCl_(3)rarrunderset((C ))(N_(2)(g))+3CaCl_(2)+3H_(2)O`
`underset((C))(N_(2)(g))+3Mgrarrunderset((D))(MgN_(2))`
`underset((D))(Mg_(3)N_(2))+6H_(2)Orarr3Mg(OH)_(2)+underset((B))(2NH_(3))`
