Chlorine reacts with saturated hydrocarbons at room temperature in the _______.
(A) absence of sunlight
(B) presence of sunlight
(C) presence of water
(D) presence of hydrochloric acid
Answer: We have
The given redox reaction can be represented as:
Cl2(g) + So2(aq) + Cl-(aq) + So42-(aq)
The oxidation half reaction is:
S+4O2(aq) → S+6O42-(aq)
The oxidation number is balanced by adding two electrons as:
So2(aq) → ...

In the bright sunlight, iris causes the pupil to become smaller so that only a small portion of light enters the eye and rods of the retina are also adjusted...
Temp = 20°C Dew point = 10°C
The place is saturated at 10°C
Even if the temp drop dew point remains unaffected.
The air has V.P. which is the saturation VP...
