A gas mixture having 75% by mass Ammonia (NH3) and the remainder Argon (Ar) is passed through a Membrane Filter to recover the Ar. There are two streams, (i) recovered stream with 60% by mass Ar and (ii) waste gas. The recovered stream comprises twenty-five percent (25%) of the inlet gas mass. The inlet flow rate is 100 kmol /hr of gas (total flow in). Calculate the composition and mass flow rate of the waste gas.

2.00mole of nitrogen (N2) gas and 2.00mole of argon (Ar) gas are in separate, equal-sized, insulated containers at the same temperature. The containers are then connected and the gases (assumed ideal) allowed to mix. PART A: What is the change in entropy of the system? PART B: What is the change in entropy of the environment? PART C: Repeat part A but assume one container is twice as large as the other.

An atom of beryllium (m = 8.00 u) splits into two atoms of helium (m = 4.00 u) with the release of 92.2 keV of energy. Suppose the beryllium atom moved in the positive x direction and had a kinetic energy of 44.0 keV. One of the helium atoms is found to be moving in the positive x direction. Find the direction of motion of the second helium, and find the velocity of each of the two helium atoms. Solve...
