A mixture of gaseous reactants is put into a cylinder, where a chemical reaction turns them into gaseous products. Thie 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. 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.
a. Is the reaction exothermic or endothermic?
b. Does the temperature of the water bath go up or down?
c. Does the piston move in or out?

Darla claims that the first periodic table developed by mendeleev was not completely accurate, so it is not useful at all. harmony argues that it establish the periodic table we use today, making it more credible. who is correct and why? darla is correct, because a model that has any mistakes should be thrown out. darla is correct, because a good model would not need to change. harmony is correct, because mendeleev’s model had all of the information correct in the first version. harmony is correct, because mendeleev’s model made predictions that came true.
