Question

Write balanced ionic equations and net ionic equations for the following reactions.

Answer 1

The ionic equation will be: 
Mg2+(aq) + 2OH-(aq) + 2H+(aq) + 2NO3-(aq) → Mg2+(aq) + 2NO3-(aq) + 2H2O(l) 
And the net ionic: 
2OH-(aq) + 2H+(aq) → 2H2O(l) 
a Balanced equation would be:
Mg(OH)2(aq) + 2HNO3(aq) → Mg(NO3)2 (aq) + 2H2O(l) 
Now  thsi si so because of the standard equation which is base plus acid=Salt plus water. We need to have in mindo that Mg(OH)2 is sparingly soluble in water and is aqueous mos of the times
