Balanced equation

Balance the chemical equation algebraically: NaOH + MnO_2 + KClO_3 ⟶ H_2O + KCl + Na2MnO4 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 NaOH + c_2 MnO_2 + c_3 KClO_3 ⟶ c_4 H_2O + c_5 KCl + c_6 Na2MnO4 Set the number of atoms in the reactants equal to the number of atoms in the products for H, Na, O, Mn, Cl and K: H: | c_1 = 2 c_4 Na: | c_1 = 2 c_6 O: | c_1 + 2 c_2 + 3 c_3 = c_4 + 4 c_6 Mn: | c_2 = c_6 Cl: | c_3 = c_5 K: | c_3 = 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_3 = 1 and solve the system of equations for the remaining coefficients: c_1 = 6 c_2 = 3 c_3 = 1 c_4 = 3 c_5 = 1 c_6 = 3 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: |   | 6 NaOH + 3 MnO_2 + KClO_3 ⟶ 3 H_2O + KCl + 3 Na2MnO4
