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.
Answer:
Explanation:
solid would be a wall e.g
liquid would be water e.g
gas would be oxygen e.g

Explanation:
Hello!
In this case, since the combustion reaction of methanol is:
In such a way, since there is 1:3/2 mole ratio between methanol and oxygen, we can compute the moles of oxygen that are needed to burn 2.56 moles of methanol as shown below:
Best regards!
Answer:
The chemical formula for ammonium hypochlorite is NH4ClO.
The chemical formula for ammonium nitrate is NH4NO3.
Explanation:
These two are correct
