WebHess’s Law Enthalpy of Reaction and Hess's Law ABSTRACT. The goal of this lab is to perform experiments and practice Hess’s Law by determining enthalpy change in chemical reactions. In this lab, three experiments were conducted in order to test Hess’s Law. The experiments required observing and collecting data on three different reactions. Webthe reactions According to Hess's Law, if two or more reactions can be added to give a net reaction, Δ H° for the reaction is the sum of the Δ H°'s for the reactions which are added? In this lab,-ending the enthalpy of formation for MgO (s) was done by -ending the enthalpies for the net of the reaction that gives MgO as a product. Here are ...
