Balanced equation

Balance the chemical equation algebraically: KOH + KClO_3 + PoO_2 ⟶ H_2O + KCl + K2PoO4 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 KOH + c_2 KClO_3 + c_3 PoO_2 ⟶ c_4 H_2O + c_5 KCl + c_6 K2PoO4 Set the number of atoms in the reactants equal to the number of atoms in the products for H, K, O, Cl and Po: H: | c_1 = 2 c_4 K: | c_1 + c_2 = c_5 + 2 c_6 O: | c_1 + 3 c_2 + 2 c_3 = c_4 + 4 c_6 Cl: | c_2 = c_5 Po: | c_3 = c_6 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 = 6 c_2 = 1 c_3 = 3 c_4 = 3 c_5 = 1 c_6 = 3 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: |   | 6 KOH + KClO_3 + 3 PoO_2 ⟶ 3 H_2O + KCl + 3 K2PoO4
