Magnesium oxide Calculate the amount of heat energy (q) in kJ that was absorbed by the surroundings, calorimeter and water, for each sub-reaction. Use 1.01 g/mL for the density of the HCl solutions. Use the specific heat of water, 4.184 J/(g·°C), for all solutions. The calorimeter constant is 25.5 J/°C.
