Answer:
493.02 nm is the longest wavelength of light that will produce free chlorine atoms in solution.
Explanation:
,ΔH = 242.8 kJ/mol
Energy required to break 1 mole of Cl-Cl bond = 242.8 kJ
Energy required to break 1 Cl-Cl bond = E
![E = \frac{242800 J}{6.022\times 10^{23}}=4.032\times 10^{-19} J](https://tex.z-dn.net/?f=E%20%3D%20%5Cfrac%7B242800%20J%7D%7B6.022%5Ctimes%2010%5E%7B23%7D%7D%3D4.032%5Ctimes%2010%5E%7B-19%7D%20J)
Energy related with the wavelength of light is given by Planck's equation:
![E=\frac{hc}{\lambda }](https://tex.z-dn.net/?f=E%3D%5Cfrac%7Bhc%7D%7B%5Clambda%20%7D)
![\lambda =\frac{hc}{E}](https://tex.z-dn.net/?f=%5Clambda%20%3D%5Cfrac%7Bhc%7D%7BE%7D)
![=\frac{6.626\times 10^{-34} Js\times 3\times 10^8 m/s}{4.032\times 10^{-19} J}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B6.626%5Ctimes%2010%5E%7B-34%7D%20Js%5Ctimes%203%5Ctimes%2010%5E8%20m%2Fs%7D%7B4.032%5Ctimes%2010%5E%7B-19%7D%20J%7D)
![\lambda = 4.930\times 10^{-7} m = 493.02 nm](https://tex.z-dn.net/?f=%5Clambda%20%3D%204.930%5Ctimes%2010%5E%7B-7%7D%20m%20%3D%20493.02%20nm)
![1 m = 10^09 nm](https://tex.z-dn.net/?f=1%20m%20%3D%2010%5E09%20nm)
493.02 nm is the longest wavelength of light that will produce free chlorine atoms in solution.
A homogenous mixture is evenly distributed.... meaning you CAN NOT see the different parts. A heterogeneous mixture is not which means you CAN see the different parts.

Answer and Explanation
The isomer picked is the N-Propylamine.
It has a lone pair of electron available on the electron rich Nitrogen and no formal charge.
Since it will be hard to draw the Lewis structure in this answer format, I'll attach a picture of the Lewis structure to this answer.
The lone pair of electron is shown by the two dots on the Nitrogen atom.
