What happens when:
(a)`NH_(4)Cl` & `NaNO_(3)` is heated strongly. , (b)`(NH_(4))_(2)CO_(3)` is heated. , ( c)`NH_(4)NO_(2)` is heated.
(d)`Mg_(3)N_(2)` reacts with water. , (e)`Mg` is burnt in air and the product is treated with water.

Answer

(a)`NH_(4)Cl+NaNO_(3)toNH_(4)NO_(3)+NaCl ; NH_(4)NO_(3) overset(Delta)to N_(2)O+2H_(2)O`
(b)`(NH_(4))_(2)CO_(3) overset(Delta)to 2NH_(3)+CO_(2)H_(2)O`, (c )`NH_(4)NO_(2) overset(Delta)to N_(2)+2H_(2)O
(d)`Mg_(3)N_(2) + 6H_(2)O overset(Delta) to 3 Mg(OH)_(2)+2NH_(3)`
(e)`2Mg+O_(2)overset(Delta)to 2MgO ; 3Mg+N_(2) overset(Delta) Mg_(3)N_(2) ; Mg_(3)N_(2) +6H_(2)O overset(Delta) to 3 Mg(OH)_(2)+2NH_(3)`
