Question

Hi I need help with these following questions. I have all of the data needed.

Calculate the enthalpy change of the reaction for each trial (in kJ)

3. Calculate the heat released by the reaction for each trial (in J):


2. Calculate the heat absorbed by the calorimeter for each trial (in J):


Calculate the heat absorbed by the solution for each trial (in J):


-Mass of the empty calorimeter (g): 18.600g
-Initial temperature in the calorimeter (oC): 21.5 C
-Maximum temperature in the calorimeter from the reaction (oC): 30.7 C
-ΔT (oC) 9.2 C
-Mass of the calorimeter and its contents after the reaction (g):69.0g
-Mass of the solution, e - a (g)50.4g
-Moles of Mg reacted: 0.0062 moles

Thank you for your help!
