In a bomb calorimeter compartment surrounded by 1.144 kg of water, the combustion of 1.081 g of benzene, C6H6 (l), raised the temperature of the water from 23.640°C to 32.692°C. The heat capacity of the calorimeter is 0.852 kJ/°C. What is ∆E for the reaction in kJ/mol of C6H6 (l), the specific heat of water is 4.184 J/g°C. Enter the correct sign (+ or -). Enter to 0 decimal places.

The characteristic of two different types of reactions are shown below. reaction a: electrons are gained by the atoms of an element. reaction b: protons are lost by the atom of and element. which statement is true about the atoms of the elements that participate in the two reactions? a: their identity changes in both reaction a and b. b: their identity changes in reaction a but not b. c: their identity changes in reaction b but not a. d: their identity remains the same.
