Question

Write the Net Ionic Equation of the following:

a) silver nitrate and ammonia

b) barium nitrate and ammonia

c) magnesium nitrate and ammonia

d) zinc nitrate and ammonia

Answer 1

a) AgNO₃ + NH₃ AgH(s) + NH₂NO₃

Ag⁺ +NO₃^- + NH₂⁺ + H^- AgH(s) + NH₂⁺ +NO₃^-

by cancelling each other on both sides

Ag+ _(lq) + H^-_(lq) AgH(s)

b) Ba(NO₃)₂ +NH₃ BaH₂

Ba⁺ + NO₃^- + NH₂^-+ H⁺

byarranging it will gives

Ba²⁺ + 2NO₃ + 2NH₂⁺+ 2H⁺ BaH₂ + 2NH₂⁺ + 2NO₃^-

By cancelling each other

Ba²⁺_(lq) + 2H^+₍lq) BaH_2(s)

c)

Mg²⁺ + NO₃^- + NH₂⁺+H^- MgH₂ + NH₂NO₃

   Mg²⁺ + NO₃^- + NH₂⁺+H^-    MgH₂+ NH₂⁺ + NO₃^-

by cancelling both sides

Mg²⁺_(lq) + H^-_(lq) MgH_2(s)

d)

Zn²⁺ + NO₃^- + NH₂⁺+H^- ZnH₂ + NH₂NO₃

_Zn²⁺ + NO₃^- + NH₂⁺+H^-    ZnH₂+ NH₂⁺ + NO₃^-

by cancelling both sides

Zn²⁺_(lq) + H^-(lq) MgH_2(s)
