i cant figure out the net ionic equation

Question

1.Write a net ionic equation for the overall reaction that occurs when aqueous solutions of carbonic acid and sodium hydroxide are combined. Assume excess base. 

2.Write a net ionic equation for the reaction that occurs when aqueous solutions of perchloric acid and barium hydroxideare combined.

Answer 1

H2CO3 (aq) + 2NaOH (aq) -> 2 H2O (l) + Na2CO3 (aq) ... molecular equation

H2CO3 (aq) + 2Na⁺ (aq) + 2OH^- (aq) ->2 H2O (l) + 2Na⁺ (aq) + CO3^2- (aq) ... complete ionic

H2CO3 (aq) + 2OH^- (aq) -> 2 H2O (l) + CO3^2- (aq) ... net ionic

NOTE: since carbonic acid (H2CO3) is a weak acid, we do not ionize it so it stays as is on the left side of the equation.

2HClO3(aq) + Ba(OH)2(aq) -> 2H2O(l) + Ba(ClO3)2(aq) ... molecular equation

2H⁺(aq) + 2ClO3^-(aq) + Ba²⁺(aq) + 2OH^-(aq) -> 2H2O(l) + Ba²⁺(aq) + 2ClO3^-(aq) ... complete ionic

2H⁺(aq) + 2OH^-(aq) -> 2H2O(l) ... net ionic
