Three 1.0-l flasks, maintained at 308 k, are connected to each other with stopcocks. initially the stopcocks are closed. one of the flasks contains 1.5 atm of n2, the second 2.2 g of h2o, and the third, 0.30 g of ethanol, c2h6o. the vapor pressure of h2o at 308 k is 42 mmhg and that of ethanol is 102 mmhg. the stopcocks are then opened and the contents mix freely. what is the pressure

An equilibrium mixture of pcl5(g), pcl3(g), and cl2(g) has partial pressures of 217.0 torr, 13.2 torr, and 13.2 torr, respectively. a quantity of cl2(g) is injected into the mixture, and the total pressure jumps to 263.0 torr (at the moment of mixing). the system then re-equilibrates. the appropriate chemical equation is pcl3(g)+cl2(g) < --> pcl5(g) calculate the new partial pressures after equilibrium is reestablished in torr
