=-72-88 kJ/mol. 10. A reaction known to release 1.78kJ of heat takes place in a calorimeter containing 0.100L 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...
8.000g of Compound X with molecular formula C4H6 are burned in a constant-pressure calorimeter containing 15.00kg of water at 25C. The temperature of the water is observed to rise by 5.801C. (You may assume all the heat released by the reaction is absorbed by the water, and none by the calorimeter itself.) Calculate the standard heat of formation of Compound X at 25C.
