How do i solve a double replacement reaction?

Question

Balance and then write the net ionic equation.

I know that (aq) stands for dissolved water

 

 

NH4CL (aq) + Mg (OH)2 (aq) -> MgCl2 (aq) + NH3 (g) + H2O (l)

Answer 1

2NH4Cl (aq) + Mg(OH)2 (aq) ==> MgCl2 (aq) + 2NH3 (g) + 2H2O (l)  balanced equation

 

2NH4^+(aq) + 2OH^-(aq)  ==> 2NH3(g) + 2H2O(l)  net ionic equation

 

The Mg and the Cl are spectator ions.  (aq) = aqueous;  (g) = gas;  (l) = liquid
