A mixture of gaseous reactants is put into a cylinder, where a chemical reaction turns them into gaseous products. The cylinder has a piston that moves in or out, as necessary, to keep a constant pressure on the mixture of 1atm. The cylinder is also submerged in a large insulated water bath. (See sketch at right.)From previous experiments, this chemical reaction is known to absorb 386.kJ of energy. The temperature of the water bath is monitored, and it is determined from this data that 181.kJ of heat flows out of the system during the reaction.

The density of water is 1.00g/mL and the heat capacity of ice to be 37.7 J mol-1K-1 and the heat capacity of water is 75.3 J mol-1K-1. The molar enthalpy of fusion of water is 6.01 kJ/mol and the heat capacity of iron is 0.45 J/(gK).
P6.32 In a bomb calorimeter, a sample is placed into an inner combustion cham- ber and combusted to CO, and H,O. The combustion chamber sits inside another chamber which is filled with an exact amount of water. The tem- perature of the outer chamber is carefully monitored. In one experiment, 2.7 g of a proprietary organic chemical with the molecular formula C,H,0, is placed in a bomb calorimeter and combusted. In the outer chamber, which contains 650 g water, the temperature increases from 23.6°C to 36.2°C. Use these data to calculate an enthalpy of formation (kJ/g) for the unknown chemical. oduce suvelling and
