Write a net ionic equation for the overall reaction that occurs when aqueous solutions of hydrosulfuric acid (H2S) and sodium hydroxide are combined. Assume excess base. Use the pull-down boxes to specify states such as (aq) or (s).
___ (aq) (s) (l) (g) + (aq) (s) (l) (g)
(aq)(s)(l)(g) + (aq) (s) (l) (g)

H2S(g) + 2OH^-(aq) >  S^2-(aq) + 2H2O(l)

Explanation:

We know that the net ionic equation shows the major reaction that occurs in the reaction system.

The molecular reaction equation is;

H2S(g) + 2NaOH(aq) > Na2S(aq) + 2H2O(l)

The complete ionic equation is;

H2S(g) + 2Na^+(aq) + 2OH^-(aq) > 2Na^+(aq) + S^2-(aq) + 2H2O(l)

Net ionic equation;

H2S(g) + 2OH^-(aq) >  S^2-(aq) + 2H2O(l)

that's what i got you can count the number of atoms
