Experiment 5: Calorimetry and Hess’s LawClass: Chemistry1250Name: Zehan IraniDue Date: Thursday 13th, FebruaryTA’s name: Si-Han Chen
PurposeCalibrate and use a calorimeter to determine enthalpy change for two different reactions.Relate temperature measurements and heat transferred by using heat capacities or specificheat. Use thermochemical equations to relate the change in enthalpy to the amount ofsubstances involved in the reaction. Use Hess’s Law to determine the enthalpy change fora chemical reaction.ProcedurePlease refer toChemistry 1250 General Chemistry Laboratory Manual, 2013,Department of Chemistry, The Ohio State University, Hayden McNeil, Exp 6, pages 45-58, for the proper procedure.
GraphsResult and Discussion In this experiment we had to use two copper cylinders which we heated first in boiling hot water, whichrose the tempereature of the copper cylinders to 99.4 oC . we then transferred the cylinders into a coffe cup calorimeter and recorded the change in
