Thermochemistry: An Ice Calorimeter Determination of Reaction Enthalpy Khuong Bui CHM 152 LL 47095 September 15, 2010 Instructor: John Weide Abstract : We do the experiment on thermochemistry to know about the heat transfer takes place with no temperature change–it is an isothermal heat transfer. We prepare a table including the pipet readings as a function of time. When we read the pipet to 0.001-mL precision, we can record the time. At first we put 5 mL of H 2 SO 4 to the tube and record the level of water in every 30s for 5 min. after that add contained 0.2052 g of Mg to the tube and read the level of the pipet for every 30s. The result we can have two tables to compare and know how the heat transfer makes the different of level water in the pipet. Lab partner : Dustin Gaines Finding the change in level of water in a pipet because of heat transfer.
