In a bomb calorimeter compartment surrounded by 1.409 kg of water, the combustion of 1.343 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 0.892 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.

Calcium carbonate decomposes at high temperatures to give calcium oxide and carbon dioxide as shown below. caco3(s) cao(s) + co2(g) the kp for this reaction is 1.16 at 800°c. a 5.00 l vessel containing 10.0 g of caco3(s) was evacuated to remove the air, sealed, and then heated to 800°c. ignoring the volume occupied by the solid, what will be the mass of the solid in the vessel once equilibrium is reached?
