Balanced equation

Balance the chemical equation algebraically: H_2O + KMnO_4 + C_3H_6 ⟶ KOH + MnO_2 + CH_3CH(OH)CH_2OH Add stoichiometric coefficients, c_i, to the reactants and products: c_1 H_2O + c_2 KMnO_4 + c_3 C_3H_6 ⟶ c_4 KOH + c_5 MnO_2 + c_6 CH_3CH(OH)CH_2OH Set the number of atoms in the reactants equal to the number of atoms in the products for H, O, K, Mn and C: H: | 2 c_1 + 6 c_3 = c_4 + 8 c_6 O: | c_1 + 4 c_2 = c_4 + 2 c_5 + 2 c_6 K: | c_2 = c_4 Mn: | c_2 = c_5 C: | 3 c_3 = 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 = 2 c_2 = 1 c_3 = 3/2 c_4 = 1 c_5 = 1 c_6 = 3/2 Multiply by the least common denominator, 2, to eliminate fractional coefficients: c_1 = 4 c_2 = 2 c_3 = 3 c_4 = 2 c_5 = 2 c_6 = 3 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 4 H_2O + 2 KMnO_4 + 3 C_3H_6 ⟶ 2 KOH + 2 MnO_2 + 3 CH_3CH(OH)CH_2OH
