Consider two identical boxes filled with hydrogen atoms. The atoms in Box A are illuminated by a beam of ultraviolet light, while the atoms in Box B collide with a beam of electrons. The light has a wavelength of 97.3 nm in vacuum. Each electron in the electron beam has the same energy as each photon in the beam of light.

For electrons, the potential energy levels are the difference between the excited energy state that the atom is knocked into subtracted from the ground state 12.75 eV. The possible values are 2.55 eV, 0.65 eV, and 12.75 eV.

Please show how the three values above are calculated.

3. (a) Two ideal gases are placed in separate, identical steel boxes. Each box has an identical pinhole through which the contained gas may effuse. One gas is Xe, while the other gas is an unknown––but elemental–– gas. The Xe totally effuses in 32.0 minutes, while the unknown gas totally effuses in 23.5 minutes. What is a likely identity for the unknown gas? Show your work. (b) A quantity of the tryptamine alkaloid psilocin, whose molecular weight is 204.27 g...

There are 5 boxes. One box is empty; two boxes each contains one marble; and the remaining two boxes each contains two marbles. Suppose that the colors of the marbles are not known, but it is known that each marble can only be either red or green, with equal probability. Suppose that ONE box is randomly chosen from the 5 boxes, and let R denote the number of the red marble(s) the box has, and G be the number of...

The Columbus Dispatch conducted a study. Two identical football, one filled with helium and one filled with ordinary air, were used. A casual observer was unable to detect a difference in the two footballs. A novice kicker was used to punt the footballs. A trial consisted of kicking both footballs in a random order. The kicker did not know which football he was kicking. The distance of each punt was recorded, then another trial was conducted. A total of 39...

We look at a collision between two identical atoms that form a molecule in the process. We assume that each atom has mass ? and can be considered as a point particle. We assume that all external forces are small relative to the forces between the atoms. We therefore do not need to take consideration of some external forces. We begin with a simplified model where the connection is instant (without spring). Atom A moves in ?direction in distance ?...
