(a)

Answer to Problem 19.7QP
Explanation of Solution
In balancing nuclear equation, the sum of atomic number and the mass number must match on both sides of the equation.
On the left side of the equation, atomic number sum is 13(12+1) and the mass number sum is 27(26+1).these sum must be the same on the right side of the same equation.
Note that the atomic and mass number of an alpha particle are 2and 4, respectively.
For a beta- particle (
For neutron particle (
So the number of X is there for 11(13-2) and the mass number is 23(27-4).
So the X is sodium -23(

Answer to Problem 19.7QP
Explanation of Solution
On the left side of the equation the atomic number sum is 28(27+1) and the mass number sum is 61(59+2).
These sums must be the same on the right side.
Note that the atomic and mass number of an alpha particle are 2and 4, respectively.
For a beta- particle (
For neutron particle (
The atomic number of X is there1 (13-2).and the mass number is also 1(61-60).
X is a proton (

Answer to Problem 19.7QP
Explanation of Solution
In balancing nuclear equation, the sum of atomic number and the mass number must match on both sides of the equation.
On the left side of the equation, atomic number sum is 236(235+1) and the mass number sum is 92(92+0).these sum must be the same on the right side of the same equation.
For a beta- particle (
For neutron particle (
On the right side of the equation, atomic number sum is 233 = (94+139) and the mass number sum is 92(92+0). These sum must be the same on the right side of the same equation.
So the number of X is there for mass number (3) and the 0 for atomic number is 3(3*1)
So the X is neutron
(d)

Answer to Problem 19.7QP
Explanation of Solution
On the left side of the equation the atomic number sum is 92(92/0) and the mass number and the mass number sum is 236(235-1).
These sums must be the same as the sum in right side and the mass number is same on the rigid also.
The atomic number of x there of X is therefore
On the left side of the equation the atomic number sum is 26(24+2) and the mass number sum is 57(53+4).
These sums must be the same on the right side.
Note that the atomic and mass number of an alpha particle are 2unit and 4, respectively.
For a beta- particle (
For neutron particle (
The atomic number of X is therefore 26 (26-0).and the mass number is also 56(57-1).
X is iron-56(

Answer to Problem 19.7QP
Explanation of Solution
On the left side of the equation atomic number sum is 8 and mass number sum is 20.
The sums must be the same on the right side.
The atomic number of X is there for -1(8-9) and the mass number is 0(20-20).
X is a beta-(

- 32. Consider a two-state system in which the low energy level is 300 J mol 1 and the higher energy level is 800 J mol 1, and the temperature is 300 K. Find the population of each level. Hint: Pay attention to your units. A. What is the partition function for this system? B. What are the populations of each level? Now instead, consider a system with energy levels of 0 J mol C. Now what is the partition function? D. And what are the populations of the two levels? E. Finally, repeat the second calculation at 500 K. and 500 J mol 1 at 300 K. F. What do you notice about the populations as you increase the temperature? At what temperature would you expect the states to have equal populations?arrow_forward30. We will derive the forms of the molecular partition functions for atoms and molecules shortly in class, but the partition function that describes the translational and rotational motion of a homonuclear diatomic molecule is given by Itrans (V,T) = = 2πmkBT h² V grot (T) 4π²IKBT h² Where h is Planck's constant and I is molecular moment of inertia. The overall partition function is qmolec Qtrans qrot.
