Abstract This lab is performed in order to determine the total energy in a reaction between zinc and hydrochloric acid. The reaction is done twice‚ once to measure the heat of the reaction and again to determine the work done in the system. This is because Enthalpy equals heat plus work (∆H= ∆E+W). Heat and work can be broken down further into separate components so the equation used in lab is ∆H=mc∆T + PV. Many calculations are used in the lab to find out what cannot be measured directly (ex:

Abstract The aim of this experiment is to determine the heat of combustion for naphthalene. This is the some basic bomb procedures. In this experiment‚ we us naphthalene as a fuel in bomb calorimeter which naphthalene powder is turned to pellet using pellet press. The fuel is burnt at constant volume condition in a high pressure container (the bomb). The whole bomb‚ pressurized with excess of oxygen. The mass of iron wire‚ ma =0.02g. The mass of naphthalene pellet with iron wire‚ mb =0.38g. The

His last lines “what have I done” do clarify his intent but due to the fact that he falls on the plunger there was no ample clarification for the same. There is a possibility that due to his love for the bridge built by the British soldiers he had just proceeded towards the plunger to disconnect it‚

August of 1997‚ there were reports of a police brutality outrage in New York City. All over the country there were newspapers that Abner Louima‚ a Haitian immigrant to the US was arrested and taken into a restroom‚ beat severely and sodomized with a plunger handle. Although this is not acknowledged as something more than excessive force by the NYPD forces‚ it is not the only incident that involves excessive force. These incidents have even failed to put any blame on police departments because they
