Balanced equation

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 = 3 c_3 = 4 c_4 = 1 c_5 = 4 c_6 = 3 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 4 KMnO_4 + 3 CH_3CH_2OH ⟶ 4 H_2O + KOH + 4 MnO_2 + 3 CH_3COOK
