Answer:
Joule-Thomson coefficient for an ideal gas:
Explanation:
Joule-Thomson coefficient can be defined as change of temperature with respect to pressure at constant enthalpy.
Thus,
![\mu_{J.T} = \left [\frac{\partial T}{\partial P} \right ]_H](https://tex.z-dn.net/?f=%5Cmu_%7BJ.T%7D%20%3D%20%5Cleft%20%5B%5Cfrac%7B%5Cpartial%20T%7D%7B%5Cpartial%20P%7D%20%5Cright%20%5D_H)
Also,
![dH= \left [\frac{\partial H}{\partial T}\right ]_P dT + \left [\frac{\partial H}{\partial P}\right ]_T dT](https://tex.z-dn.net/?f=dH%3D%20%5Cleft%20%5B%5Cfrac%7B%5Cpartial%20H%7D%7B%5Cpartial%20T%7D%5Cright%20%5D_P%20dT%20%2B%20%5Cleft%20%5B%5Cfrac%7B%5Cpartial%20H%7D%7B%5Cpartial%20P%7D%5Cright%20%5D_T%20dT)
Also, 
is defined as:
![C_p = \left [\frac{\partial H}{\partial T}\right ]_P](https://tex.z-dn.net/?f=C_p%20%3D%20%5Cleft%20%5B%5Cfrac%7B%5Cpartial%20H%7D%7B%5Cpartial%20T%7D%5Cright%20%5D_P)
![dH= C_p dT + \left [\frac{\partial H}{\partial P}\right ]_T dT](https://tex.z-dn.net/?f=dH%3D%20C_p%20dT%20%2B%20%5Cleft%20%5B%5Cfrac%7B%5Cpartial%20H%7D%7B%5Cpartial%20P%7D%5Cright%20%5D_T%20dT)
Acoording to defination, the ethalpy is constant which means 
![\left [\frac{\partial H}{\partial P}\right ]_T = -C_p\times \left [\frac{\partial T}{\partial P}\right ]_H](https://tex.z-dn.net/?f=%5Cleft%20%5B%5Cfrac%7B%5Cpartial%20H%7D%7B%5Cpartial%20P%7D%5Cright%20%5D_T%20%3D%20-C_p%5Ctimes%20%5Cleft%20%5B%5Cfrac%7B%5Cpartial%20T%7D%7B%5Cpartial%20P%7D%5Cright%20%5D_H)
![\mu_{J.T} = \left [\frac{\partial T}{\partial P}\right ]_H](https://tex.z-dn.net/?f=%5Cmu_%7BJ.T%7D%20%3D%20%5Cleft%20%5B%5Cfrac%7B%5Cpartial%20T%7D%7B%5Cpartial%20P%7D%5Cright%20%5D_H)
![\left [\frac{\partial H}{\partial P}\right ]_T =-\mu_{J.T}\times C_p](https://tex.z-dn.net/?f=%5Cleft%20%5B%5Cfrac%7B%5Cpartial%20H%7D%7B%5Cpartial%20P%7D%5Cright%20%5D_T%20%3D-%5Cmu_%7BJ.T%7D%5Ctimes%20C_p)
For an ideal gas,
![\left [\frac{\partial H}{\partial P}\right ]_T = 0](https://tex.z-dn.net/?f=%5Cleft%20%5B%5Cfrac%7B%5Cpartial%20H%7D%7B%5Cpartial%20P%7D%5Cright%20%5D_T%20%3D%200)
So,
Thus, 
≠0. So,
Answer: Option (d) is the correct answer.
Explanation:
Carbon tetrachloride 
is a non-polar solvent. Whereas out of the given options, 
, 
, 
, and HI are all polar molecules.
On the other hand, only 
is non-polar molecule.
Also it is known that like dissolves like.
So, being non-polar 
will dissolve the give alkane, .
Answer: Chemistry is the study of change. Various reasons why to study Chemistry is to appreciate the fundamentals of the world such as the composition of all living thing. We are made up of matter. The interaction of sub atomic particles in an atom to form a single being. Also to understand how certain chemicals are beneficial and harmful in our lives just by reading product labels.
