Suppose that something had gone "wrong" in the Big Bang and, instead of ordinary hydrogen, there was an abundance of deuterium in the Universe. There would be many subtle changes in equilibria, particularly the deuteron transfer equilibria of heavy acids and bases. The Kw for D20, at 25 °C, is 1.35 x 1015. Calculate the pD and pOD in neutral heavy water at 25 °C. Ans: 745

THERMOCHEMISTRY = 1/3 Tanvi V Understanding the definitions of heat and work 1 atm pressure 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.) From previous experiments, this chemical reaction is known to absorb 298. kJ of energy. gases The position of the piston is monitored, and it is determined from this data that the piston does 212. kJ of work on the system during the reaction.
