Enthalpy H is a measure of the energy content of a system at constant pressure. Chemical reactions involve changes in enthalpy, AH, which can be measured and calculated: -Σροoducts mΔΗ-Σactants ηΔΗ where the subscript "rxn" is for "enthalpy of reaction" and "f" is for "enthalpy of formation" and m and n represent the appropriate stoichiometric coefficients fo each substance. The following table lists some enthalpy of formation values for selected substances. Substance AH÷° (kJ/mol) CO2 (g) -393.5 NaOH(s) -426.7 H20(1) -285.8 Na2 CO3 (s) -1131.0 H2O(g) -241.8
