Calculate enthalpy change of reaction for the combustion of gaseous ethanol.

C2H5OH + 3O2 >> CO2 + 3H2O.
Using standard molar enthalpies of formation.
C2H5OH -235.3 ( it's negative sign)
CO2 -393.5
H2O -241.8
(1) Calculate the enthalpy change of reaction per mole of ethanol
(2) Calculate enthalpy change of reaction when 1000 g of ethanol are burned with enough oxygen.
