Calculate the standard enthalpy change for the reaction between 2.00 moles of liquid ethanol (C2H5OH) and 3.50 moles of gaseous oxygen (O2) to form carbon dioxide (CO2) gas and liquid water (H2O) at 25°C and standard pressure. The balanced chemical equation for the reaction is C2H5OH + 3O2 → 2CO2 + 3H2O. (The molar enthalpies of formation for C2H5OH, CO2, and H2O are -277.6 kJ/mol, -393.5 kJ/mol, and -285.8 kJ/mol, respectively.)
