EXPERIMENT 9 ENTHALPY OF REACTION—HESS S LAW

WebHess' law allows the enthalpy change (ΔH) for a reaction to be calculated even when it cannot be measured directly. This is accomplished by performing basic algebraic operations based on the chemical equation of reactions using previously determined values for the enthalpies of formation. royalcraft milan corner lounge set
