Certain salts of benzoic acid have been used as food additives for decades. The potassium salt of benzoic acid, potassium benzoate, can be made by the action of potassium permanganate on toluene according to the following reaction (unbalanced):             C7H8  +   KMnO4  ® KC7H5O2  +   MnO2  +  KOH  + H2O           toluene                      potassium                                             benzoate   Balance the equation. What is the limiting reactant when 10.750 g of toluene react with 14.750 g of potassium permanganate? How much of the excess reactant remains after all of the limiting reactant is consumed?
