During experiment, a student adds 1.81 g of CaO to 300.0 mL of 1.000 M HCI. The student a observes a temperature increase of 5.00 degree C. Assuming the solution's final volume is 300.0 ml, the density if 1.00 g/mL, and the is heat capacity is 4.184 J/(g degree C), calculate the heat of the reaction, delta H_ CaO (s) + 2H^+ (aq) rightarrow Ca^2+ (aq) + H_2 O (l) delta H_ =
