A B H rxn1 C D H rxn2 A + C B +D H rxn1 + H rxn2 Heats of reaction will be determined calorimetrically The heat given off by the reaction is absorbed by the calorimeter and the aqueous solution.-H rxn = q solution + q calorimeter Calculating the heat absorbed by the calorimeter is requires a calorimeter constant, C c . The calorimeter constant is determined in Part A . q calorimeter = C c ( T) The heat absorbed by the aqueous solution can be calculated from data collected in Parts B and C . q solution = mC H2O ( T) = (m acid + m Mg,MgO )C H2O ( T) Chem. 117 Experiment #8 Chp. 9.4 - 9.6-H rxn = q solution + q calorimeter = (m acid + m Mg,MgO )C H2O ( T) + C c ( T)...
