If one benzene molecule is placed in water, the total entropy of the water + benzene system:___________
valkas [14]

Answer:

d) increases

Explanation:

Benzene is an aromatic hydrocarbon which is obtained from the destructive distillation of coal. It is a colourless volatile liquid with a sweet smell. It boils ar 80° C (353 K) and freezes at 5°C (2278 K). It is insoluble in water but mixes in all proportions with ethanol, ethoxyethane and methylbenzene. The reason which benzene is insoluble in water is that benzene is a non-polar compound and water is polar, meanwhile only "like dissolves like". So, when the benzene molecule is placed in water. There will be distortion and disturbance between the benzene molecule and the water. Thus, the particle of each molecule will be distant from each other. This state results to change in the entropy of the system as the entropy of the system increases.

Depending upon the tip of a dropper pipet there are approximately 20 drops per milliliter of water. the experimental procedure p
Murrr4er [49]

Answer : The volume range in milliliters for the solution is 0.25 - 0.5 mL

Explanation :

We have been given that there are approximately 20 drops per milliliter of water

This information can be used as a conversion factor as \frac{1mL}{20 drops}

We are using 5-10 drops of the solution.

Let us calculate milliliters in 5 drops.

5 drops \times\frac{1 mL}{20 drops} = 0.25 mL

Similarly, 10 drops would contain

10 drops \times\frac{1 mL}{20 drops} = 0.5 mL solution.

Therefore the volume range in milliliters for the solution is 0.25 - 0.5 mL
