Question

13.00g of Compound X with molecular formula C4H6 are burned in a constant-pressure calorimeter containing 15.00kg of water at

25°C. The temperature of the water is observed to rise by 9.363°C. (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 25°CBe sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits.
