Answer:
hydrological cycle
Explanation:
water cycle is also known as hydrological vycle
Answer:
The equilibrium is shifted to the formation of OH⁻.
Explanation:
AH + OH⁻ ⇄ A⁻ + H₂O
At the equivalence point, the acid AH has entirely been converted to A⁻, which is its conjugated base. This causes the equilibrium to shif to consume the excess of A⁻, which leads to production of OH⁻. This is why, at the equivalence point, the pH is larger than 7.
Taking into account the definition of dilution, moles of solute (option C) is the only thing about the solution that does NOT change.
<h3>Dilution</h3>
When it is desired to prepare a less concentrated solution from a more concentrated one, it is called dilution.
Dilution is the process of reducing the concentration of solute in solution, which is accomplished by simply adding more solvent to the solution at the same amount of solute.
In a dilution the amount of solute does not change, but as more solvent is added, the concentration of the solute decreases, as the volume (and weight) of the solution increases.
A dilution is mathematically expressed as:
Ci×Vi = Cf×Vf
where
- Ci: initial concentration
- Vi: initial volume
- Cf: final concentration
- Vf: final volume
<h3>Summary</h3>
In summary, moles of solute (option C) is the only thing about the solution that does NOT change.

Answer:
The electronic structures of pentacene/MoO3/Al and pentacene/Al were studied using in situ photoemission spectroscopy. The secondary electron cutoffs, highest occupied molecular orbitals (HOMOs) and core level changes were measured upon deposition of the pentacene and MoO3 to study the electronic structures at the interface.
