Final answer:
The balanced chemical equation for this reaction is 3 Ba(NO3)2(aq) + 2Na3PO4(aq) → Ba3(PO4)2(s) + 6NaNO3(aq).
Step-by-step explanation:
The balanced chemical equation for the reaction is:
3 Ba(NO3)2(aq) + 2Na3PO4(aq) → Ba3(PO4)2(s) + 6NaNO3(aq)
This equation is balanced using the smallest possible whole number stoichiometric coefficients, which ensures that the number of each type of atom is equal on both sides of the equation.
