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.

Consider a helium ion He+. a) Find the ratio between the ionization energy of the H atom and and the He^+ ion. b) How does the Bohr radius, we defined for H atom, differ for He^+ ? Using the Bohr radius of He^+ and the representation of the ground state wave function for the H atom, write the ground state wave function for the He^+. c) Find the average distance of a 1s electron from a nucleus in He+ ion....

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.
