4. Bacteria can sour wine and beer by converting ethanol (C2H5OH) into ethanoic ac (CH3COOH) : Overall Equation: C2H5OH(1)+O2(g)CH3COOH(1)+H2O(1) The following enthalpy changes are determined using a bomb calorimeter. C2H5OH0)+3O2(g)2CO2(g)+3H2O(i)CH3COOH(1)+2O2(g)2CO2(g)+2H2O(1)Hcomb=1367kJHcomb=875kJ a. Use Hess's Law, and the complete combustion equations, to determine enthalpy change for the Overall Equation. (4 marks) b. Draw structural diagrams for each of the molecules in the Overoll Equation. (4 marks) c. Use bond energies to determine the enthatpy change of the Overall Equation. (4) marks) How do the enthalpy change values you have calculated compare? Which of the enthalpy change values do you believe to be more accurate? Explain your answer. (2 marks)
