Input interpretation
(NH4)3PO4 + Pb(NO3)4 ⟶ ammonium nitrate + Pb3(PO4)4
Balanced equation
Balance the chemical equation algebraically: (NH4)3PO4 + Pb(NO3)4 ⟶ + Pb3(PO4)4 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 (NH4)3PO4 + c_2 Pb(NO3)4 ⟶ c_3 + c_4 Pb3(PO4)4 Set the number of atoms in the reactants equal to the number of atoms in the products for N, H, P, O and Pb: N: | 3 c_1 + 4 c_2 = 2 c_3 H: | 12 c_1 = 4 c_3 P: | c_1 = 4 c_4 O: | 4 c_1 + 12 c_2 = 3 c_3 + 16 c_4 Pb: | c_2 = 3 c_4 Since the coefficients are relative quantities and underdetermined, choose a coefficient to set arbitrarily. To keep the coefficients small, the arbitrary value is ordinarily one. For instance, set c_4 = 1 and solve the system of equations for the remaining coefficients: c_1 = 4 c_2 = 3 c_3 = 12 c_4 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 4 (NH4)3PO4 + 3 Pb(NO3)4 ⟶ 12 + Pb3(PO4)4
