When KHCO3 is heated, it decomposes into potassium carbonate, water, and carbon dioxide. By applying Hess's law and using the results from #2 and #3, calculate the enthalpy change for the thermal decomposition of potassium hydrogen carbonate. Show all work and explain. Carefully note whether enthalpy changes are exothermic or endothermic.
