Input interpretation
sodium hydroxide + P2O5 ⟶ water + trisodium phosphate
Balanced equation
Balance the chemical equation algebraically: + P2O5 ⟶ + Add stoichiometric coefficients, c_i, to the reactants and products: c_1 + c_2 P2O5 ⟶ c_3 + c_4 Set the number of atoms in the reactants equal to the number of atoms in the products for H, Na, O and P: H: | c_1 = 2 c_3 Na: | c_1 = 3 c_4 O: | c_1 + 5 c_2 = c_3 + 4 c_4 P: | 2 c_2 = 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_2 = 1 and solve the system of equations for the remaining coefficients: c_1 = 6 c_2 = 1 c_3 = 3 c_4 = 2 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 6 + P2O5 ⟶ 3 + 2
