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.)

Calculate the standard enthalpy change for the complete combustion of 2 moles of methane gas under standard conditions, where all reactants and products are in their standard states. The balanced chemical equation for the combustion of methane is CH4(g) + 2O2(g) → CO2(g) + 2H2O(l), and the standard enthalpy of formation ΔH°f for methane, carbon dioxide, and water are -74.8 kJ/mol, -393.5 kJ/mol, and -285.8 kJ/mol, respectively.

Calculate the standard enthalpy change (ΔH°) for the reaction of combustion of 1 mole of ethanol (C2H5OH) given that the standard enthalpy of formation (ΔH°f) for ethanol and carbon dioxide (CO2) are -277.7 kJ/mol and -393.5 kJ/mol respectively, and the standard enthalpy of formation (ΔH°f) for water (H2O) is -285.8 kJ/mol. The balanced chemical equation for the reaction is as follows:C2H5OH (l) + 3 O2 (g) → 2 CO2 (g) + 3 H2O (l)
