WebChemistry B Unit 3, Lesson 8 – Enthalpy Lab Question: How can you use Hess's law to determine a reaction's enthalpy when you can't do so using a calorimeter? The combustion of magnesium has the equation Mg(s) + 1/2O 2 (g) → MgO(s). This reaction gives off enough heat that it could melt a coffee cup calorimeter, making it difficult to compute the … WebHess' law tells us that the enthalpy change of a reaction is always the same, regardless of the route taken. Therefore, the enthalpy change of the direct route, route 1, is also -124. …
