net ionic equation. Aqueous acetic acid (HC2H3O2) is neutralized by aqueous barium hydroxide.

i got H^+(g) + OH^-(g) --> H_2O(l) but it is wrong. are my states of matter wrong?

Yes, your states of matter are wrong. Since they are aqueous solutions, hydrogen and hydroxide should be written as (aq) not (g) since niether are gases.
Also you didn't balance the equation.
2HC2H3O2 + Ba(OH)2 ==> Ba(C2H3O2)2 + 2H2O
So I would write the nt ionic equation as
2H^+(aq) + 2OH^-(aq) ==> 2H2O(l)
