#8 please 7. An oxygen tank in a laboratory has an internal pressure of 12 atm at 25°C. If the pressure inside the tank exceeds 25 atm, the tank will explode. A fire breaks out in the laboratory raising the temperature of the gas cylinder to 398 "C. Show how to determine and then calculate the final internal pressure of the tank and indicate if the tank will explode or is safe may assume that the volume of the tank...
A mixture of oxygen and helium gases, in a 9.44 L flask at 61 °C, contains 7.69 grams of oxygen and 0.430 grams of helium. The partial pressure of helium in the flask is atm and the total pressure in the flask is atm. back is
Mixtures of helium and oxygen are used in scuba diving tanks to help prevent "the bends". For a particular dive, 42.3 L of oxygen gas at 25.0°C and 1.25 atm, and 8.00 L of helium gas at 25.0°C and 1.62 atm were pumped into a tank with a volume of 6.00 L at 25.0°c Calculate (in atm) 1. the partial pressure of oxygen 2. the partial pressure of helium 3. the total pressure in the tank at 25.0°C. The tank...
Mixtures of helium and oxygen are used in scuba diving tanks to help prevent "the bends". For a particular dive, 27.5 L of oxygen gas at 25.0°C and 1.84 atm, and 7.90 L of helium gas at 25.0°C and 2.95 atm were pumped into a tank with a volume of 6.00 L at 25.0°C. Calculate (in atm): 1. the partial pressure of oxygen 2. the partial pressure of helium 3. the total pressure in the tank at 25.0°C.
Mixtures of helium and oxygen are used in scuba diving tanks to help prevent "the bends". For a particular dive, 32.1 L of oxygen gas at 25.0°C and 1.45 atm, and 7.07 L of helium gas at 25.0°C and 2.45 atm were pumped into a tank with a volume of 6.00 L at 25.0°C. Calculate (in atm): 1. the partial pressure of oxygen 2. the partial pressure of helium 3. the total pressure in the tank at 25.0°C.
Mixtures of helium and oxygen are used in scuba diving tanks to help prevent "the bends. For a particular dive, 32.3 L of oxygen gas at 25.0°C and 1.75 atm, and 7.28 L of helium gas at 25.0°C and 2.77 atm were pumped into a tank with a volume of 6.00 L at 25.0°C Calculate (in atm) 1. the partial pressure of oxygen 2. the partial pressure of helium 3, the total pressure in the tank at 25.0°C.

just need answers -- no solutions 14a A mixture of nitrogen and krypton gases, in a 6.64 L flask at 13 °C, contains 8.14 grams of nitrogen and 7.40 grams of krypton. The partial pressure of krypton in the flask is atm and the total pressure in the flask is atm. 14b A mixture of methane and helium gases is maintained in a 5.88 L flask at a pressure of 1.90 atm and a temperature of 86 °C. If the gas...
We put a mixture of helium, oxygen and nitrogen gases in a closed container at 25 ° C. Container pressure in this case is 300 kPa. By a process, we remove all helium gas in the mixture from the closed container. Container pressure in this case reaches 250 kPa. What percentage of the gas mixture did the initial mixture of helium molecules contain? If there are 14 grams of nitrogen and 32 grams of oxygen in this container, what is...
