Answer:
The partial pressure of chlorine gas in the mixture is 1.55 atm.
Explanation:
Partial pressure of oxygen gas = 
Partial pressure of nitrogen gas = 
Partial pressure of chlorine gas = 
Total pressure of the mixture of gases = P = 3.30 atm
Using Dalton's law of partial pressure:



The partial pressure of chlorine gas in the mixture is 1.55 atm.
Answer: Option (B) is the correct answer.
Explanation:
A molecules that will have more number of hydrogen bonding will has highest boiling point because to break the hydrogen bonds high heat needs to be provided.
So, in the molecule
there is presence of two alcoholic groups. Hence, it will have strongest hydrogen bonding as compared to the rest of molecules.
In the molecule
there will be hydrogen bonding and dipole-dipole interactions. Hence, it boiling point will be slightly less than
.
In the molecule
, there will be only hydrogen bonding. Hence, its boiling point is less than
.
In the molecule
, there is no hydrogen bonding but there will be only dipole-dipole interactions. Hence, its boiling point will be the least.
Therefore, we can conclude that increasing order of boiling point will be as follows.

All I know is these things hope they help u.
Explanation:

The maximum wavelength of light that can cause this reaction is 420 nm.
a) The wavelength given lies in the range of visible light range that is from 400 nano meters to 700 nano meters.
The light with wavelength of 420 nm is found in the range of visible light.
b)The maximum strength of a bond :

where,
E = energy of photon = Energy required to break single molecule of nitrogen dioxide
h = Planck's constant = 
c = speed of light = 
= wavelength = 


Energy required to break 1 mole of nitrogen dioxide molecules:


(1 J = 0.001 kJ )
285.13 is the maximum strength of a bond, in kJ/mol, that can be broken by absorption of a photon of 420-nm light.
c) the photodissociation reaction showing Lewis-dot structures is given in an image attached.
