A 15.0-L tank containing 1.0 mol of argon gas is at 298 K. (a) Calculate the initial pressure of the gas and d, the length of the cube containing this volume. (b) Using your value for d, calculate the energies of the two lowest translational energies for the system E1,1,1 and E2,1,1 and their differences ΔE . (c) The tank is opened and the gas is allowed to expand rapidly into a cubical 2000L room such that there is no heat...

Imagine that you have a 6.00 L gas tank and a 2.50 L gas tank. You need to fill one tank with oxygen and the other with acetylene to use in conjunction with your welding torch. If you fill the larger tank with oxygen to a pressure of 105 atm , to what pressure should you fill the acetylene tank to ensure that you run out of each gas at the same time? Assume ideal behavior for all gases. Express...

Imagine that you have a 7.00 L gas tank and a 3.00 L gas tank. You need to fill one tank with oxygen and the other with acetylene to use in conjunction with your welding torch. If you fill the larger tank with oxygen to a pressure of 155 atm , to what pressure should you fill the acetylene tank to ensure that you run out of each gas at the same time? Assume ideal behavior for all gases.

A 200-L home heater tank contains butane gas (C4H10) at 26.0 °C. When some of the butane is removed and burned in excess air, the pressure in the tank drops from 2.34 atm to 1.10 atm. The energy generated in the combustion is then used to raise the temperature of 132.5 L of water from 19.0°C to 71.3 °C. Useful Information: ΔH°f (CO2 (g)) = –393.5 kJ/mol ΔH°f (H2O (l)) = –285.8 kJ/mol Density of water = 1 g/mL →Calculate...
