Answer: precipitation of 
from 
and 
ions in solution
Explanation:
Entropy is the measure of randomness or disorder of a system. If a system moves from an ordered arrangement to a disordered arrangement, the entropy is said to decrease and vice versa.
is positive when randomness increases and is negative when randomness decreases.
a) precipitation of from and ions in solution : As ions are getting solidified, entropy decreases.
b) dissolution of 
in water: The compounds dissociates into ions, entropy increases.
c) melting solid gold into liquid gold: The randomness increases, entropy increases.
d) evaporation of Hg(l) to form Hg(g) : The randomness increases, entropy increases.
e) mixing of two gases into one container : The randomness increases, entropy increases.
The composition would be more "diluted" in a sense.

Answer:
[Ar] 3d10 4s2 4p3 is shorthand, 1s22s22p63s23p63d104s24p3 long hang
Explanation:
The shorthand is made using the lowest & closest noble gas, and picking up where it leaves off as follows, and longhand is made from a followed pattern you can easily find
