5.000 g of compound x with molecular formula c₄h₆ are burned in a constant-pressure calorimeter containing 25.00 kg of water at 25°c. the temperature of the water is observed to rise by 2.161 °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°c.
be sure your answer has a unit symbol, if necessary, and round it to 3 significant digits.
