Input interpretation
sodium hydroxide + sodium permanganate ⟶ water + oxygen + Na2MnO4
Balanced equation
Balance the chemical equation algebraically: + ⟶ + + Na2MnO4 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 + c_2 ⟶ c_3 + c_4 + c_5 Na2MnO4 Set the number of atoms in the reactants equal to the number of atoms in the products for H, Na, O and Mn: H: | c_1 = 2 c_3 Na: | c_1 + c_2 = 2 c_5 O: | c_1 + 4 c_2 = c_3 + 2 c_4 + 4 c_5 Mn: | c_2 = c_5 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_4 = 1 and solve the system of equations for the remaining coefficients: c_1 = 4 c_2 = 4 c_3 = 2 c_4 = 1 c_5 = 4 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 4 + 4 ⟶ 2 + + 4 Na2MnO4
