Explanation:
At each reflecting surface (benzene and glass) there will be 180 degree phase change.
Now, for constructive interference the optical path in benzene is
.
Formula to calculate thickness of a benzene thin film is as follows.
Optical path length through benzene (
) = 
Hence, substituting the given values into the above formula as follows.
Optical path length through benzene = 
d = 
=
=
(as 1 nm = 
= 204.9 m
Thus, we can conclude that minimum thickness of benzene is 204.9 m.
If ALL individuals of a species were not able to have offspring, then that species would eventually become extinct.

Answer:
Sodium ion and atom are both sodium-atoms, sodium ion is only the state of sodium-atom due to change in valence electrons, at this ion state time it is highly reactive, due to it’s reactivity they are unstable by there nature and try to search there partner element-atoms to make a stable ionized compound.
