Question: Using the two equations below and the provided data table, calculate the standard enthalpy of formation of H 2 S (g). 2H 2 S (g)

Using the two equations below and the provided data table, calculate the standard enthalpy of formation of H2S (g).

2H2S (g) + 3O2 (g) ® 2H2O (l) + 2SO2 (g)             DHө = - 1124 kJ/mol

S (s) + O2 (g) ® SO2 (g)                                          DHө = - 296.8 kJ/mol
