Answer:

#Ba(NO_3)_2(aq) + Na_2CO_3(aq) rarr BaCO_3(s)darr + 2NaNO_3(aq)#

Explanation:

And the net ionic equation is:

#Ba^2+ + CO_3^(2-) rarr BaCO_3(s)darr #

Barium carbonate is quite insoluble in aqueous solution, #K_"sp"=2.58xx10^(−9)#, and should precipitate in this #"metathesis (partner exchange) reaction"#

Would you expect #BaCO_3# to be more soluble in a weakly acidic solution? Why or why not?
