Replacement Reaction

Page Count: 2
Length: 482 Words

This laboratory exercise studied the enthalpy change of a chemical reaction between magnesium (Mg) and hydrochloric acid (HCl). The experiment is designed to calculate the energy released from a single replacement reaction (Arami, 1999). The reaction is exothermic, i.e. it gives off heat. An empty calorimeter was weighed and the temperature of the calorimeter recorded. A 0.15g sample of Mg was added to 50 mL HCl in the calorimeter with a thermometer attached. The maximum temperature reached during the reaction was recorded. The final weight of the calorimeter plus its contents was then recorded. The procedure was repeated using 0.25g and 0.35g Mg. Calculations were
