when 2.36 g of a nonvolatile solute is dissolved in 100 g of solvent, the largest change in freezing point will be achieved when the solvent is when 2.36 g of a nonvolatile solute is dissolved in 100 g of solvent, the largest change in freezing point will be achieved when the solvent is water, kf
The largest change in freezing point will be achieved when the solvent is tert-butanol, and Kf = 9.1.
What is freezing point?
The temperature at which a liquid turns into a solid is known as the freezing point. Similar to the melting point, the freezing point typically rises with increasing pressure. In the case of combinations and for some organic substances, such as lipids, the freezing point is lower than the melting point.
Concept of colligative property is applied here.
In this case, particularly freezing point depression.
The formula is for this is:
[tex]\delta T = K_f \times m \times i[/tex]
When we add particles of a certain solute, freezing point of a solution becomes lower than the pure solvent.
i = Van't Hoff factor (ions particles that are dissolved in the solution)
In this case, the solute is nonvolatile, so i values 1.
δT = Difference between fusion T° of pure solvent - fusion T° of solution.
T° fusion paradichlorobenzene = 56 °C
T° fusion water = 0°
T° fusion tert-butanol = 25°
Water has the lowest fusion temperature and the paradichlorobenzene has the highest Kf. But the the tert-butanol, has the highest Kf so this solvent will have the largest change in freezing point, when all the concentrations are the same.

7. How does the density of water compare with the density of the saturated salt solution?
Is this what you would have predicted?
We can see that the density of the water is less than the density of the saturated salt solution from the table shown above.
What is density?The term density is defined as the ratio of the mass to the volume of an object. In this case, we can see that we are trying to compare the density of water and the density of a salt solution. We have to recall that when we dissolve a solute in a solvent, the density of the solution would change to reflect that we no longer have a pure solvent.
This is because, the density of a substance is an intrinsic property thus it then depends on the nature of the substance and not on the amount of the substance.
Thus, we can see that when we dissolve the salt in the water, the density of the water is increased. Thus water has a density of 1 g/mL while a saturated salt solution has a density of 1.12 g/mL.

why do substances exist in liquids solids or gasses
Matter exists in different states such as solid, liquid and gas because of the kinetic energy of its particles and the intermolecular force of attraction between the particles.
A substance won't condense into a liquid or solid if the average kinetic energy is higher than the attraction forces holding the particles together.
Thus in solids, intermolecular force of attraction > kinetic energy of particles.
In a liquid (or solid), the average kinetic energy of the particles is low enough to allow the forces of attraction to hold the particles together. In a liquid (or solid), molecules do not separate.
In liquids, intermolecular force of attraction > kinetic energy of particles. But this force of attraction is smaller than solids.
The forces of attraction between the particles in a gas can be overcome by the average kinetic energy of the particles in the gas. When gas molecules collide, they spread apart.
In gas, intermolecular force of attraction < kinetic energy of particles.

A liquid partially vaporises into the space above it at any temperature up until the vapour pressure of the liquid at that temperature, which is a characteristic value. When a liquid reaches its boiling point, vapour bubbles form inside the liquid and rise to the surface as the temperature rises, increasing the vapour pressure.

what happens when an electric current is passed through a solution of an ionic compound
Whenever ionic chemicals are melted or dissolved in water, an electric current is produced. The B ions migrate toward the positive electrode in an ionic solution, while the A+ ions migrate toward the negative electrode.
Always dissociated, which means they are made up of independent cations (+) and anions, which are ionic compounds or salts (-). For instance, even in the solid state, there are just Na+ and Cl- ions in common salt, NaCl, and nothing that is "NaCl."
But the ions need to travel in order to conduct electricity. In the solid state, it is impossible to do this. Therefore, dry solid salts with no moisture at all are poor electrical conductors. The ions may travel, thus when they are in liquid form (melted) or solution (dissolved in water), they conduct electricity.
In other words, they conduct electricity because they are dissociated, not because electrical current is flowing through them.

The pressure (in atm) of the carbon (IV) oxide, CO₂ gas collected, during the given experiment is 0.965 atm
How to determine the Pressure (in atm) of CO₂We'll beging by obtaining the pressure (in torr) of the carbon (IV) oxide, CO₂ gas collected. This can be obtained as follow:
Pressure of lab = 752 torrVapour pressure of water at 21 ° C = 18.65 torrPressure of CO₂ = ?Pressure of CO₂ = (Pressure of lab) - (Vapour pressure of water at 21 ° C)
Pressure of CO₂ = 752 - 18.65
Pressure of CO₂ = 733.35 torr
Finally, we shall convert 733.35 torr to atm as illustrated below
We know that:
760 torr is equivalent to 1 atm
Therefore,
733.35 torr will be equivalent = (733.35 torr × 1 atm) / 760 torr
