Answers:
a) 
b)
c) X rays have the energy to disrupt organic compounds by breaking carbon–carbon single bonds, but AM radio waves not.
Explanation:
The energy of a photon in Joules is given by the following formula:
(1)
However, if we want to know this energy in units of
, we have to use the following formula:
(2)
<h2>
a) Now, in the case of X rays:</h2>
(3)
Where:
is the energy of X rays in Joules (
)
is the Planck constant
is the speed of light
is the wavelength of X rays
is the Avogadro's number
(4)
(5) This is the energy of X rays in units of kilojoules per mole
<h2>
b) For AM radio waves:</h2>
(6)
Where:
is the energy of AM radio waves in Joules (
)
is the wavelength of AM wavelength
(7)
(8) This is the energy of AM radio waves in units of kilojoules per mole
<h2>c) Which is able to disrupt
carbon–carbon single bonds?</h2>
If we compare the energy of both (X rays and AM radio waves) with the energy of a carbon–carbon single bond (
), we will have the following:

This means the energy of X rays is greater than the energy of AM radio waves and greater than the energy of carbon–carbon single bond as well:

In addition, this means X rays have the energy to disrupt organic compounds by breaking carbon–carbon single bonds, but AM radio waves not.
