The purpose of this lab is to calculate the ∆h of the reaction of ammonia (nh3) and hydrochloric acid (hcl) to form ammonium chloride (nh4cl) using the principals of hess’s law applied to calorimetry background: thermochemistry is the study of the energy change associated with chemical.

Sharifi 1 determining the validity of hess’s law through calorimetry sch 4u1 mrs bhardwaj by: pooyan sharifi sharifi 2 introduction/ background info according to albert einstein’s equation (e=mc2) everything in the universe that has a mass contains energy. Thermochemistry lab #2 - heat of reaction - hess's law return the foundation of the study of thermochemistry was laid by the chemist germain hess, who investigated heat in chemical reactions during the last century.
Hess's law, also known as hess's law of constant heat summation, states that the total enthalpy of a chemical reaction is the sum of the enthalpy changes for the steps of the reaction therefore, you can find enthalpy change by breaking a reaction into component steps that have known enthalpy.
