Input interpretation
P2O5 + perchloric acid ⟶ phosphoric acid + dichlorine heptoxide
Balanced equation
Balance the chemical equation algebraically: P2O5 + ⟶ + Add stoichiometric coefficients, c_i, to the reactants and products: c_1 P2O5 + c_2 ⟶ c_3 + c_4 Set the number of atoms in the reactants equal to the number of atoms in the products for P, O, Cl and H: P: | 2 c_1 = c_3 O: | 5 c_1 + 4 c_2 = 4 c_3 + 7 c_4 Cl: | c_2 = 2 c_4 H: | c_2 = 3 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 = 6 c_3 = 2 c_4 = 3 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | P2O5 + 6 ⟶ 2 + 3
