Assume that heat was not absorbed by the container or lost to the surroundings, that the density of H20 is 1.00g/mL, and that the specific heat capacity of H2O is about 4.2J/g.°C. Based on this information, estimate how much heat was released from the combustion of the benzoic acid sample. a. 0.013 kJ b. 25 kJ c. 180 kJ d. 210 kJ Temperature (°C)
