In this lab experiment students are asked to determine the standard molar enthalpy of formation of magnesium oxide, MgO. Students are asked to use Hess's Law and the enthalpy changes of several other solution reactions during this...

Young scholars observe and perform experiments with sodium, potassium, calcium, magnesium, sulfur ,and phosphorus. The discover trends down groups, across periods, and having to do with the pH of metal oxides vs. nonmetal oxides.
