Input interpretation
H2MnO4 ⟶ water + manganese dioxide + HMnO4
Balanced equation
Balance the chemical equation algebraically: H2MnO4 ⟶ + + HMnO4 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 H2MnO4 ⟶ c_2 + c_3 + c_4 HMnO4 Set the number of atoms in the reactants equal to the number of atoms in the products for H, Mn and O: H: | 2 c_1 = 2 c_2 + c_4 Mn: | c_1 = c_3 + c_4 O: | 4 c_1 = c_2 + 2 c_3 + 4 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_3 = 1 and solve the system of equations for the remaining coefficients: c_1 = 3 c_2 = 2 c_3 = 1 c_4 = 2 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 3 H2MnO4 ⟶ 2 + + 2 HMnO4
