A is evaporation because it's going from the sea up to the sky.
B is condensation because it shows cloud formation.
C is precipitation because rain is falling
D is well, water in the sea.
Final answer: B
Answer:
The answer to the question is a
Answer:
The following must be true for diffusion of a solute to occur across a partition that separates two compartments
The partition is semi permeable
There is concentration gradient across the partition
The process is known as Osmosis
Explanation:
Diffusion is the migration of particles of a substance, liquid or gas, from a region of high concentration to a region of lower concentration and it only occurs where there is a concentration gradient for example spraying a perfume at a corner of a room, the spray sent spreads across the room as there is a concentration gradient
Osmosis is the movement or diffusion of solvent molecules across a semi permeable membrane from a region of low solute concentration to a region of high solute concentration to create a balanced concentration of solute on both sides of the compartment.
Here we have to get the the 
of the solution containing HOBr and KOBr.
The of the solution is 8.47
The mixture of HOBr and KOBr is a buffer solution. The of the buffer solution is determined by the Henderson equation which is:
= 
+ log ![\frac{[salt]}{[acid]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Bsalt%5D%7D%7B%5Bacid%5D%7D)
Here [salt] i.e. KOBr is 0.30 mol/L and [Acid] is 0.50 mol/L.
The 
value of HOBr is 2×10⁻⁹.
We know, = -log
Or, = -log (2×10⁻⁹)
Or, = 8.698
On plugging the values:
= 8.698 + log 
Or, = 8.698 - 0.221
Or, = 8.47
Thus the of the solution is 8.47.
