How do you write the chemical equation for neutralization of nitric acid, HNO3, with magnesium hydroxide, Mg (OH)2, first with spectator ions and then without spectator ions?
The molecular equation is
2HNO3 + Mg(OH)2 ==> Mg(NO3)2 + 2H2O. If these are in solution (the problem doesn't say that but the implication is that they are, then
2HNO3(aq) + Mg(OH)2(aq) ==> Mg(NO3)2(aq) + 2H2O(l)
Net ionic equation is
2H^+ + 2OH^- ==> 2H2O and if you really want to do it up brown you write
2H^+(aq) + 2OH^-(aq) ==> 2H2O(l)
