Input interpretation
ammonia + phosphoric acid ⟶ (NH4)3PO4
Balanced equation
Balance the chemical equation algebraically: + ⟶ (NH4)3PO4 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 + c_2 ⟶ c_3 (NH4)3PO4 Set the number of atoms in the reactants equal to the number of atoms in the products for H, N, O and P: H: | 3 c_1 + 3 c_2 = 12 c_3 N: | c_1 = 3 c_3 O: | 4 c_2 = 4 c_3 P: | c_2 = c_3 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_2 = 1 and solve the system of equations for the remaining coefficients: c_1 = 3 c_2 = 1 c_3 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 3 + ⟶ (NH4)3PO4
