Enthalpy Change of a Chemical Reaction

Paper Summary:

This paper describes a chemistry experiment in enthalpy change during chemical reactions. It looks at the enthalpy change in the reaction between magnesium and hydrochloric acid. The experimental method is described and the results analyzed. The write-up shows details of the experiment recorded and how the calculations are made.

From the Paper:

"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. The reaction is exothermic, i.e., it gives off heat. An empty calorimeter was weighed and the temperature of the calorimeter recorded. A g sample of Mg was added to mL HCl an the calorimeter with a thermometer attached. The maximum temperature reached during the reaction was recorded. The final weight of the calorimeter..."
