Question
Hello, pls answer correctly and pls answer this immediately
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.) 1 atm pressure piston From previous experiments, this chemical reaction is known to release 189. kJ of energy. gases The temperature of the water bath is monitored, and it is determined from this data that 218. kJ of heat flows into the system during the reaction. O exothermic Is the reaction exothermic or endothermic? O endothermic O up Does the temperature of the water bath go up or down? O down O neither O in Does the piston move in or out? O out O neither O does work Does the gas míxture do work, or is work done O work is done on it on it? O neither How much work is done on (or by) the gas mixture? Be sure your answer has the correct number of significant digits.
