Experiment 9: Enthalpy of Formation of Magnesium Oxide

www.bc.edu

The enthalpy of formation of liquid H2O has been measured and is given by: ΔH°rxn(4) = ΔH°f(H2O) = –285840 Joules/mole = –285.84 kJ/mol The enthalpies of reactions (2) and (3) are measurable quantities. Heat is released by the addition of excess strong acid to one mole (24.3 g) of Mg, thus the quantity ΔH°rxn(2) will be a negative number.
