Because the aqueous solution is very dilute, we can assume that the specific heat of the solution is the same as the specific heat of water. Use correct significant figures. Show your work only for Trial 1:aTrial 1 (J)bTrial 2 (J)   
  cTrial 3 (J)   . Calculate q_calorimeter, using the heat capacity of the calorimeter provided (21.3 J/°C) along with the temperature change for each trial in this experiment. Use correct significant figures. Show your work only for Trial 1:aTrial 1 (J)bTrial 2 (J)   
  cTrial 3 (J)   Calculate q_reaction. Use correct significant figures. Show your work only for Trial 1:aTrial 1 (J)bTrial 2 (J)   
  cTrial 3 (J)   Find the enthalpy change (DH) for the reaction in each trial in units of kilojoules/(mole of Mg). Use correct significant figures. Show your work only for Trial 1.aTrial 1 (kJ/mol)  bTrial 2 (kJ/mol)   cTrial 3 (kJ/mol)   What is the average enthalpy change (DH) for the three results?Use the average enthalpy change, DH, you determined from this experiment to predict the amount of heat that should be released when 3.0 mol Mg reacts with excess HCl.
