10. A reaction known to release 1.78kJ of heat takes place in a calorimeter containing 0.10OL of solution and the temperature rose by 3.65°C. The calorimeter was then rinsed out and emptied. To the empty calorimeter was placed a small piece of calcium carbonate and 0.100L of dilute HCI was poured over it (in the same calorimeter). The temperature of the calorimeter then rose by 3.57°C. What is the heat, q, in kJ released by the reaction? Remember to include the correct sign in your answer. Show your work/calculations:
