Alab scientist cools a liquid sample of water (2.6 kg) at 0.00°c to -192°c. the water turns to ice as this temperature change occurs. how much heat is released during this process? [for water, lf = 334 kj/kg and lv = 2257 kj/kg. the specific heat for ice is 2050 j/(kg·k)]. report your answer in kj. (round your answer to a whole number - no decimal places)

Butane gas reacts with oxygen gas to give carbon dioxide gas and water vapor (gas). if you mix butane and oxygen in the correct stoichiometric ratio, and if the total pressure of the mixture is 390 mmhg, what is the pressure (in mmhg) of water vapor after the reaction is completed (temperature and volume do not change).
