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 1 atm. The cylinder is also submerged in a large insulated water bath. (See sketch at right.) The temperature of the water bath is monitored, and it is determined from this data that 158. kJ of heat flows out of the system during the reaction. The position of the piston is also monitored, and it is determined from this data that the system does 270. kJ of work on the piston during the reaction. How much energy does the reaction absorb or release? Round your answer to 3 significant digits.

a sample of 98g of pure sulfuric acid is dissolved in 2.0 kg of water in an insulated vessel at 15°C, and thetemperature rises rapidly because of the process of forming the solution.

(b) Human bodies are actually open systems, and the main mechanism of heat loss is through the evaporation of water. What mass of water should be evaporated each day to maintain constant temperature?

1 kg of benzene is poured into a flask and heated to 353 K (the boiling point of benzeneat 1 atm.) using a heating element that has a power of 700 W (we ignore thatit's probably not so healthy and smart to do). After 5 minutes, when the benzene has stoodboiling point, the heating element is taken up, and the remaining mass of benzene in the flaskmeasured at 470 grams. Determine the enthalpy of vaporization of benzene.
