Answer:

A Plant cell contains a large vacuole which is membrane-bound organelle specialized to perform several unique functions in the plant cells like:

1. It is used by the plant to store the waste material of the cell.

2. Its major function is to store the water which provides shape and rigidity to the plant cell.

3. It maintains the rigidity as it helps maintain the turgor pressure of the plant cell.

4. It also stores the ions of the cell and thus controls the pH of the cell.

Thus, a plant vacuole serves many functions to the plant cell.

Salt water can be desalinated by distillation. How much energy is needed to convert 175 g of salt water at 28.0 °C to water vapo
Vinil7 [7]

Answer:

\Delta H=4.63x10^{5}J=463kJ

Explanation:

Hello,

In this case, we find the following states:

a. Liquid salt water at 28.0 °C.

b. Liquid salt water at 102.5 °C.

c. Vapor salt water at 102.5 °C.

The first process (1) is to heat the liquid water from 28.0 °C to 102.5 °C and the second one (2) to vaporize the liquid salt water. In such a way, each process has an amount of energy that when added, yields the total energy for the process as shown below:

\Delta H=\Delta H_1+\Delta H_2\\\Delta H=mCp\Delta T+m\Delta _VH\\\Delta H=175g*5.19\frac{J}{g*K}*(375.65K-301.15K)+175g*2.26\frac{kJ}{g} *\frac{1000J}{1kJ} \\\Delta H=4.63x10^{5}J=463kJ

Best regards.
