Input interpretation
water + P2O5 ⟶ metaphosphoric acid
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 Set the number of atoms in the reactants equal to the number of atoms in the products for H, O and P: H: | 2 c_1 = c_3 O: | c_1 + 5 c_2 = 3 c_3 P: | 2 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_1 = 1 and solve the system of equations for the remaining coefficients: c_1 = 1 c_2 = 1 c_3 = 2 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | + P2O5 ⟶ 2
