• Chemistry problems that involve enthalpy changes can be solved by techniques similar to stoichiometry problems.
  • The moles of a reactant or product can be linked to mass or volume.
  • Since pollution is often both particulate and thermal, energy changes need to be determined in addition to the amounts of products released.
  • The calculation requires two steps.
  • The mass of SO2 is converted to moles.
  • Then the mol SO1 is multiplied by the conversion factor of .
  • The result is the energy released by the reaction of sulfur dioxide and oxygen.
