LAB REPORT ON VERIFICATION OF HESS’S LAW Our purpose of doing this lab was to prove the Hess’s law correct. Hess’s law suggests that the enthalpy change of a reaction must be equal to the sum of the enthalpy changes of the related reactions which lead to the original reactions. The following are the reactions at the lab; 1) NaOH ( s) NaOH (aq) 2) NaOH (aq) + HCl (aq) NaCl (aq) + H2O (l) 3) NaOH (s) + HCl (aq) NaCl (aq) + H2O (l) As explained before‚ Hess’s Law states that the enthalpy

Harry Deeming ! 14/1/14 Chemical Plants! At the centre of a chemical plant there is a reactor‚ this is where the reactants are turned into chemicals during synthesis. The reactor often contains a catalyst which is a chemical that speeds up the reaction without itself undergoing any chemical change. The feedstock (raw material to supply/fuel machine) may need to be heated before it is fed to the reactor. ! Once the chemical reaction has taken place‚ generally a mixture of chemicals will

Rick Hess was diagnosed with diabetes in his early 40s. When he was in medical school‚ he participated in a study that analyzed insulin. His results were low and a little out of the normal levels. However‚ if he would have known more about the results like they do now‚ it would have predicted he would have become diabetic. In addition to being a diabetic‚ Rick has also had to overcome cerebrovascular disease in his 70s. Rick Hess is now 76 years old. He attended the West Virginia University to
