How can an unknown Hreaction be determined using Hess's law?A.The free energy of the reaction is used to determine the H for the reaction.B.The unknown Hreaction is determined after the reaction is run in a calorimeter.C.The reaction is repeated at different temperatures to determine the Hreaction.D.Enthalpies from reaction steps are added to determine an unknown Hreaction.

How is Hess's law used to measure enthalpy of a desired reaction?A.Intermediate equations with known enthalpies are added together.B.The enthalpy from the final equation in a series of reactions is used.C.The enthalpy is determined from the enthalpy of similar reactions.D.The enthalpy is obtained from the enthalpy of an intermediate step.
