Unformatted text preview: Purpose The goal of the experiment is to figure out the enthalpy of reaction when we burn magnesium in oxygen. By figuring out the enthalpy of reaction for the reactions between Mg(s) and HCl and MgO(s) and HCl we will be able to use Hesss Law to find the enthalpy of reaction of burning magnesium in the presence of oxygen. The purpose of the lab is also to test our knowledge on the concept of calorimetry and being able to identify different heats in reactions. We will be using a cup calorimeter, whose specific heat we will need to find by running trials with cold and hot water. After we have the capacity of the calorimeter we can test the reactions of Mg in HCl and MgO in HCl to find those heats of reaction. Again, combining those 2 with the heat of formation of water we can use Hesss law to find the enthalpy of reaction of burning Mg(s). Procedures The procedures did not change throughout the experiment and came from the online lab manual procedure for this lab experiment. Dillon, Stephanie. General Chemistry I Lab. Calorimetry .
