O2 + P4 = P2O3

Input interpretation

oxygen + white phosphorus ⟶ phosphorus trioxide
oxygen + white phosphorus ⟶ phosphorus trioxide

Balanced equation

Balance the chemical equation algebraically:  + ⟶  Add stoichiometric coefficients, c_i, to the reactants and products: c_1 + c_2 ⟶ c_3  Set the number of atoms in the reactants equal to the number of atoms in the products for O and P: O: | 2 c_1 = 3 c_3 P: | 4 c_2 = 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 = 2 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: |   | 3 + ⟶ 2
