When 02 M Sodium Hydroxide and 0 $\rightarrow$ NaNO₃(s)
B) Na⁺(aq) + OH^-(aq)

When 0.2 M sodium hydroxide and 0.2 M barium nitrate are mixed, a precipitate is formed. What is the net ionic equation for the formation of this precipitate?

A) Na⁺(aq) + NO₃^-(aq) $\rightarrow$ NaNO₃(s)
B) Na⁺(aq) + OH^-(aq) $\rightarrow$ NaOH(s)
C) Ba²⁺(aq) + 2NO₃^-(aq) $\rightarrow$ Ba(NO₃) ₂(s)
D) Ba²⁺(aq) + 2OH^-(aq) $\rightarrow$ Ba(OH) ₂(s)
E) none of these
