Classification of Oxides Magnesium Oxide Experiment Lab Report Magnesium oxide can be made by heating magnesium metal in the presence of the oxygen. In chemistry and thermodynamics, the standard enthalpy of formation or standard heat of formation of a compound is the change of enthalpy during the formation of 1 mole of the substance from its constituent elements, with all substances in their standard states.The standard pressure value p = 10 5 Pa (= 100 kPa = 1 bar) is recommended by IUPAC, although prior to 1982 the zero by definition. Magnesium oxide can be made by heating magnesium metal in the presence of the oxygen.
