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 227. kJ of heat flows into the system during the reaction. The position of the piston is also monitored, and it is determined from this data that the system does 129. kJ of work on the piston during the reaction. How much energy does the reaction absorb or release? Round your answer to 2 significant digits. [ kJ X 1 atm pressure gases
