Calculate the standard enthalpy change for this reaction using standard enthalpies of formation. Okay so here is my work after using the standard enthalpy chart to determine the ∆Hf˚ 2H2S(g)=-20.5 kJ/mol 3O2(g)=0 kJ/mol 2H2O(l)=285.8 kJ/mol 2SO2(g)-296.8 kJ/mol I put them ...
The glass bulb was broken to introduce the sample into the solution when a steady state thermal signal was obtained on the strip chart re- corder. The energy equivalent of the calorimeter was determined before each measurement by electrical cali- bration. The enthalpies of dissolution of La2O3...
