Not very much because half the time the water is purified but just normal water in my area probably has serious levels of scarcity.

After adding 20.0 mL of 5% NaOH solution into the remaining organic layer, followed by mixing and venting, the solution separate
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 <u>organic </u> 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 <u>organic </u>layer. This is so as a result of its non-polar carbon structure.

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

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

5. The organic layer was a <u>yellow</u> colored solution.

6. The aqueous layer turned into a <u>pink</u><u> </u> colored solution.

Identify the limiting reactant when 7.81 g of HCl reacts with 5.24 g of NaOH to produce NaCl and H2O
elena55 [62]

Answer:

NaOH is limiting

Explanation:

                                 Hcl   +    NaOH   ------------      Nacl   + H2O  

Given                     7.81g        5.24g

mol weights           1+35.5     23+16+1

                                 36.5            40

No of Moles        7.81/36.5       5.24/40  

                             0.2139              0.131

No of moles = weight/ molecular weight

No of moles of NaOH is  lower so it is limiting as according to equation one mole of Hcl requires mole of NaOH so equal number of moles are required. NaOH is 0.131 which is far lower than 0.2139

-------- represents arrow in forward direction in equation
