A sample of hydrogen gas (3. 2 l) at 3. 5 atm and 25 °c was combined with 5. 2 l of nitrogen gas at 7. 3 atm and 25 °c at constant temperature in a 15. 0 l flask. Assuming the initial pressure in the flask was 0. 00 atm and the temperature upon mixing was 25 °c, what is the total pressure (atm) in the flask?.

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.6 m below the tank bottom which is a = 6.7 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute). report your answer in meters to two decimal places.
