Question

**Educational Content**

**1) Write the balanced equation for the heat of formation of magnesium oxide and zinc oxide.**

**2) Using Hess’s Law, determine the enthalpy of formation of both the metal oxides, MgO and ZnO.**

To do this, you will need the balanced thermochemical equations for the two reactions studied in this lab, plus the balanced thermochemical equation for the formation of water from its elements. Clearly show below how these three equations (and their reaction enthalpies) must be combined to give the target reaction for enthalpy of formation of both the metal oxides. (For the metal/metal oxide that was not assigned to you, take the data for ΔH_rxn from students on your bench.)

Sodium hydrogen sulfate is used as a cleaning agent and as a flux (a substance that promotes the fusing of metals and prevents the formation of oxides). One of the ways in which sodium hydrogen sulfate is manufactured is by reacting sodium dichromate, Na2Cr2O7, with sulfuric acid. This process also forms water and chromium(VI) oxide, CrO3. Write a balanced equation for this reaction. (You do not need to include states.) How many kilograms of sodium dichromate, Na2Cr2O7, are necessary to produce 130.4 kg of sodium hydrogen sulfate?
