Arisa [49]

Answer:

Explanation:

The objective of this experiment is to match the expected result with each of the propositions given after the experiment had been carried out.

1. The top layer was the organic  layer. This is because all the organic compounds have lesser density than water except chloroform that will be formed when NaOH is added.

2. 9-fluorenone was most soluble in the organic layer. This is so as a result of its non-polar carbon structure.

3. Deprotonated chloroanilic acid was most soluble in the aqueous layer as a result of the formation of an electrovalent bond with water.

4. The bottom layer was the aqueous layer as a result of the huge amount of water density.

5. The organic layer was a yellow colored solution.

6. The aqueous layer turned into a pink colored solution.

The oxidation of sulfur dioxide by oxygen to sulfur trioxide has been implicated as an important step in the formation of acid r

Igoryamba

Answer:

The value of the equilibrium constant $K_p$ at this temperature is 3.42.

Explanation:

Partial pressure of the sulfur dioxide = $p_1=0.564 atm$

Partial pressure of the oxygen gas = $p_2=0.102 atm$

Partial pressure of the sulfur trioxide = $p_3=0.333$

$2 SO_2(g) + O_2(g)\rightleftharpoons 2 SO_3(g)$

The expression of an equilibrium constant is given by :

$K_p=\frac{(p_3)^2}{(p_1)^2\times p_2}$

$K_p=\frac{(0.333 atm)^2}{(0.564 atm)\times (0.102 atm)}=3.42$

The value of the equilibrium constant $K_p$ at this temperature is 3.42.
