Explanation:

The third law of thermodynamics states that "the entropy of a perfect crystal of a pure substance approaches zero as the temperature approaches zero" (Wikipedia).

One example of the third law of thermodynamics has to do with steam. Steam is gaseous water. Since it is a gas, its molecules are free to move around therefore its entropy is high. When the temperature of the steam is decreased below 100 degrees, the molecules of steam loose energy and turn into liquid water and do not move as freely as they did in the gaseous state. If the temperature is further decreased to yield ice at zero degrees, the molecules of water are "frozen" in their positions and the entropy of the system decreases to zero.

Also, the ions in ionic crystal solids move around when the substance is in solution or in molten state hence the substance conducts electricity. When the ionic substance is in solid state, the ions do not move about and the entropy of the solid system tends towards zero.

Ionic bonds form between a metal and a nonmetal.

In naming simple ionic compounds, the metal is always first, the nonmetal second (e.g., sodium chloride).

Ionic compounds dissolve easily in water and other polar solvents.

In solution, ionic compounds easily dissociate into their component ions.

Ionic compounds tend to form crystalline solids with high melting temperatures.

Ionic bonds are a type of chemical bond that forms between a metal and a nonmetal. These bonds are formed when one or more electrons are transferred from the metal atom to the nonmetal atom. This results in the formation of positively charged metal ions and negatively charged nonmetal ions, which are held together by electrostatic forces.

In naming simple ionic compounds, the metal is always named first, followed by the nonmetal. For example, NaCl is named sodium chloride. Ionic compounds are typically solids at room temperature and dissolve easily in water and other polar solvents. In solution, ionic compounds dissociate into their component ions, which allows them to conduct electricity.

Ionic compounds tend to form crystalline solids with high melting temperatures due to the strong electrostatic attraction between the positively and negatively charged ions. The lattice structure of ionic compounds is very stable and requires a large amount of energy to break apart.

When a solution is composed of two volatile components with strong solute-solvent attractions, it deviates from Raoult's law.

Raoult's law states that the vapor pressure of a component in a solution is directly proportional to its mole fraction in the solution.

In a solution with strong solute-solvent attractions, the solute molecules interact strongly with the solvent molecules, affecting the behavior of both components.

Raoult's law assumes that the vapor pressure of each component in the solution is determined solely by its mole fraction and the vapor pressure of the pure component. However, in the case of strong solute-solvent attractions, the solute-solvent interactions alter the behavior of the components, leading to deviations from Raoult's law.

A possible deviation is that the solute-solvent interactions lower the number of solvent molecules that have enough energy to escape the solution and form a vapor phase. This reduces the effective vapor pressure of the solvent in the solution. The solute molecules restrict the movement of the solvent molecules, making it more difficult for them to escape and evaporate. As a result, the observed vapor pressure of the solvent is lower than predicted by Raoult's law.

Hence, solution of two volatile components with strong solute-solvent attractions deviates from Raoult's law.

The energy was used to break the intermolecular bonds between the water molecules.

Interactions between molecules are mediated by intermolecular forces, such as the electromagnetic forces of attraction or repulsion that act between atoms and other sorts of surrounding particles, such as atoms or ions.

Intermolecular forces (IMF), frequently abbreviated, are the attractive and repulsive forces that form between the molecules of a substance. These forces act as a bridge between the individual molecules of a substance. Intermolecular forces are primarily responsible for the physical and chemical properties of matter.

The molarity of the solution is 0.234 mol/L

The molarity of a solution is the amount in moles of a solute dissolved in a given volume of solvent.

The molarity of the solution is determined as follows:

mass of electrolyte = 11 g

molar mass of electrolyte = 106.8 /mol

Number of moles of electrolyte = 11/106.8 = 0.0103 moles

density of water = 1 g/cm³

mass of water = 44 g

Volume of water = 44/1 = 44 ml or 0.044 L

Molarity of solution = 0.0103/0.044

Molarity of solution = 0.234 mol/L

In conclusion, the molarity of the solution is determined from the moles of solute and volume of solvent.

The dish with a diameter of 12 cm is likely to evaporate more quickly than the beaker with a diameter of 4.5 cm.

The dish's wider surface area allows for a greater amount of water molecules to be exposed to the air, making it easier for them to escape and evaporate into the atmosphere.

Water has a tendency to evaporate more quickly when the surface area is larger. As a result, a liquid in a dish with a diameter of 12 cm will evaporate faster than one in a beaker with a diameter of 4.5 cm.

The rate of evaporation can be determined using the formula:

rate of evaporation = amount of liquid evaporated / time

The time it takes for a given volume of water to evaporate from each container can be compared if the amount of water evaporated is identical.

The false statement is applied pressure only refers to atmospheric pressure and the correct option is option 1.

It is the ratio of the force applied to the surface area over which the force is applied. Pressure can be defined as the force applied perpendicular to the surface of an object per unit area over which that force is distributed. Atmospheric pressure is the pressure exerted by the atmosphere on the earth.

Thus applied pressure not only represents atmospheric pressure.

The pressure of hydrogen gas formed in mmHg is 745.7 mmHg. In order to find the pressure of hydrogen gas formed in mmHg, we need to make use of the Dalton's Law of Partial Pressures which states that the total pressure of a gas mixture is equal to the sum of the partial pressures of each individual gas present.

We know that the total pressure of gas collected over water is 770.0 mmHg and that the temperature is 25.5 °C. Since the gas was collected over water, we know that it must have contained some amount of water vapor. This means that the total pressure is equal to the sum of the partial pressures of hydrogen gas and water vapor. Let's use this information to find the partial pressure of hydrogen gas.1.

We can use a table or a graph to find this value. A quick search shows that the vapor pressure of water at 25.5 °C is 24.3 mmHg.2.

Now we can use the Dalton's Law of Partial Pressures to find the partial pressure of hydrogen gas. P total = PH₂ + P water PH₂ = P total - P water

PH2 = 770.0 mmHg - 24.3 mmHg

PH2 = 745.7 mmHg.

Therefore, the pressure of hydrogen gas formed in mmHg is 745.7 mmHg.

A human cell is placed into a 0.9% saline solution which is an isotonic environment. The rate of diffusion and net diffusion in this system will be same.

What is an isotonic environment?

A system in which the net movement of water molecule is almost zero is called an isotonic environment.

In this kind of environment, the rate of diffusion and effusion also remains same due to similar concentration of the dissolved molecules in the solution.

To put it simply, an isotonic environment remains unchanged and no significant changes occur in the cell size and the movement of molecules is also zero. On the contrary, in a hypotonic environment, water molecules move in and out and thus cell size changes.
