If, when electrolyzing water (2H2O --> 2H2 + O2), the total bond energy of 2 points
the reactants is 2000kJ and the total bond energy of the products is 934kJ, what is the total energy of the reaction and is this an endothermic or exothermic reaction? *
1066kJ, exothermic
-1066kJ, exothermic
-1066kJ, endothermic
1066kJ, endothermic
