Introduction WebThe actual enthalpy of the magnesium flare reaction is -603 kJ/mol. Your experimental value was likely different. Check all that apply. The coffee cup calorimeter may have absorbed some heat. The plastic coffee cup lid may have allowed some heat to escape. The thermometer did not measure the temperature of the solution properly.

WebFeb 24, 2024 · As a result, we usually calculate the change in enthalpy. Endothermic reactions have a positive enthalpy change, while exothermic reactions have a negative enthalpy change. In the laboratory, calorimetry techniques are used to measure enthalpy change. Enthalpy change is defined as the heat change at constant pressure, which is … WebEnthalpy Lab Report. 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).
