The deuteron is a bound state of a proton and a
neutron of total angular momentum j = 1. It is known to be
principally an S(ℓ = 0) state with a small admixture of a D(ℓ = 2)
state. Calculate the magnetic moment of the pure d state n-p system
with j = 1. Assume that the n and p spins are to be coupled to make
the total spin s which is then coupled to the orbital angular...
(A) A deuteron (one proton and one neutron) is traveling at 3 ·
105 m/s.
The deuteron is in a uniform electric field which causes it to
come to a stop.
(a) How much work is done by the electric field (in Joules)?
(b) Draw a diagram showing the direction of the velocity of the
particle and the force on the particle. Include the direction of
the external electric field.
(c) Draw the same diagram for an electron with the...
In a nuclear reaction an incoming proton, with an initial
velocity v1, collides with another proton, initially at rest. After
the collision one proton goes off at 37° to the direction of v1. If
the collision is perfectly elastic, find the velocities of the two
protons after the collision.
Using the data in the table, calculate the rate constant of this
reaction.

1.When a proton is moved during a reaction, what type of
catalysis is occurring? Which amino acids would be able to perform
this type of catalysis? What type of catalysis utilizes a
nucleophile? What is necessary for metal ion catalysis to occur?
How do enzymes work? How are enzymes different from other
catalysts?
Consider the reaction A → 3 B + 2C for which the
rate = k[A].
Calculate the rate constant,k, given that the initial
concentration of A is 0.0800 M and after 60s the concentration of B
is 0.027M.
Can you explain the difference between the rate of a reaction, the reaction rate, and the rate law? Also is there a difference between average rate of concentration change and instantaneous rate of concentration change, and how do they relate to the rate law? Please explain!
