answer the question with all steps provided. as much detail as possible. Hess's Law with AH Hess's law allows us to find the AH of a chemical equation using molar enthalpies of formation The AiH of many compounds are listed in your data booklet. Note: The AiH of elements is always 0 kJ We know to use Hess' Law when the question seems to lack information. Steps to Solving Problems Using Hess's Low 1. Write a balanced chemical equation 2. Figure out the AH for the reaction using the following formula: AH = E[n x AfH(products)] - [[n x AfHireactants)] I 3. Use the AH to determine what the question asks 91. Determine the molar enthalpy change of reaction of hydrogen sulfide in the following reaction below used to remove sulfur from sour gas plants in Alberta. 16H3SW + 85024 354 16H40 1
