In a vacuum chamber filled with argon gas at 100 mTorr, a plasma is ignited resulting to 1% ionization. This is already a "hot plasma" by lab processing standards. Calculate the number density of plasma electrons (should be about the same as the argon ion density due to quasineutrality) in this 1% ionized plasma.
Phenylalan ine (Phe. 1) is a naturally occurring amino acid with a benzene ring.

Take the distance between the groups as 4.0 nm and treat the benzene ring as benzene itself. Take the dipole moment of the peptide group as 2. 7 D.

When sodium metal dissolves in compressed liquid ammonia, a highly conductive blue solution is formed. This effect occurs because of solvated electrons that are effectively confined within a packet of solvent molecules. In this question, we will estimate the properties of this system. We will treat this system using the particle in a box model. a. First, derive a general expression for the energy gab using this model. In other words, calculate the difference in energy ΔE between state n+1 and state n using the constants m, L, and h. b. Assuming the transition occurs from the lowest energy state to the second state (n=1 --> n=2), estimate the length of the solvent pocket where the electron is confined. Report your answer in angstroms. Use your expression from part c. c. Higher level calculations have suggested the size of the box is approximately 11 angstroms. Based on this information and your answer to part d, comment on whether the particle in a box model provides a reasonable…
