Balanced equation

Balance the chemical equation algebraically: H_2SO_4 + KMnO_4 + CH_2=CHC(CH_3)=CH_2 ⟶ H_2O + CO_2 + K_2SO_4 + MnSO_4 + CH_2=CHCOOH Add stoichiometric coefficients, c_i, to the reactants and products: c_1 H_2SO_4 + c_2 KMnO_4 + c_3 CH_2=CHC(CH_3)=CH_2 ⟶ c_4 H_2O + c_5 CO_2 + c_6 K_2SO_4 + c_7 MnSO_4 + c_8 CH_2=CHCOOH Set the number of atoms in the reactants equal to the number of atoms in the products for H, O, S, K, Mn and C: H: | 2 c_1 + 8 c_3 = 2 c_4 + 4 c_8 O: | 4 c_1 + 4 c_2 = c_4 + 2 c_5 + 4 c_6 + 4 c_7 + 2 c_8 S: | c_1 = c_6 + c_7 K: | c_2 = 2 c_6 Mn: | c_2 = c_7 C: | 5 c_3 = c_5 + 3 c_8 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_8 = 1 and solve the system of equations for the remaining coefficients: c_2 = (2 c_1)/3 c_3 = (5 c_1)/42 + 3/7 c_4 = (31 c_1)/21 - 2/7 c_5 = (25 c_1)/42 - 6/7 c_6 = c_1/3 c_7 = (2 c_1)/3 c_8 = 1 Multiply by the least common denominator, 7, to eliminate fractional coefficients: c_2 = (2 c_1)/3 c_3 = (5 c_1)/42 + 3 c_4 = (31 c_1)/21 - 2 c_5 = (25 c_1)/42 - 6 c_6 = c_1/3 c_7 = (2 c_1)/3 c_8 = 7 The resulting system of equations is still underdetermined, so an additional coefficient must be set arbitrarily.
