Answer :
Sugar : Compound
Air : Homogeneous mixture
Hot tea : Homogeneous mixture
Salt water : Homogeneous mixture
Explanation :
Element : It is a pure substance which is composed of atoms of similar elements.
Compound : It is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.
Heterogeneous mixtures : It is a mixture that has non-uniform composition throughout the solution and the particle size or shapes are also different.
There is a physical boundary between the dispersed phase and dispersion medium.
Homogeneous mixtures : It is a mixture that has uniform composition throughout the solution and the particle size or shapes are not different.
There is no physical boundary between the dispersed phase and dispersion medium.
As per question,
Sugar : It is a compound that is made from atoms of different elements combined together in a fixed ratio by mass.
Air : It is a homogeneous mixture of the gaseous substances of nitrogen, oxygen, and smaller amounts of other substances.
Hot tea : It is a homogeneous mixture because its composition is the same throughout the solution.
Salt water : It is a homogeneous mixture because its composition is the same throughout the solution.

Element:
An element is a simplest type of a pure substance which is composed of only one type of matter. For examples; silver, gold platinum etc.
Pure substance:
A compound is a pure substance which is composed of two or more type of matter in definite proportion. For examples; water which is composed by Hydrogen and oxygen etc.
Mixture:
A mixture is made from two or more type of matter in any proportion. Mixture are generally two types:
1. Homogeneous mixture
This is also known as solution, in which the composition of the substances is uniform.
Lemon-flavored water is an example of homogeneous mixture because in this the composition of the substances is uniform.
2. Heterogeneous mixture
In this form of mixture the composition of substance are not uniform and the component of mixture also visible.
Stuffed mushrooms is an example of Heterogeneous mixture because in this form of mixture the composition of substance are not uniform and the component of mixture also visible.
B. CS2 + 3O2 yields CO2 + 2SO2
C. Mg(ClO3)2 yields MgCl2 + 2O2
D. Zn + H2SO4 yields H2 + ZnSO4
Answer:
Explanation:
(1) In the IV solution, the solute here is the NaCl salt and the solvent is the liquid (water) the salt is dissolved in.
(2) If the NaCl is replace with water, the water content will become hypotonic to the red blood cells as there would be less solute in the solution than in the cell's cytosol. This also means there is more water in the solution than in the cell's cytosol.
(3) Because the water is hypotonic to the red blood cells (as described in (2) above), the net movement of water will be into the cell.
(4) If the movement of water is allowed to continue as described in (3) above (i.e if 0.9% NaCl in the solution is replaced with pure water instead and waited), the cell will rupture which can lead to cell lysis or cytolysis.
NOTE: An isotonic solution describes when there is the same amount of solute in the cell and the solution outside the cell hence there is little or no movement of water.
In a 0.9% NaCl solution, NaCl is the solute and water is the solvent. If replaced with pure water, the water would be hypotonic to red blood cells and water would move into the cells. The red blood cells would undergo osmosis and potentially burst.
In a 0.9% NaCl solution, the sodium chloride (NaCl) is acting as the solute, while the water is acting as the solvent. If the 0.9% NaCl solution is replaced with pure water, the water would be hypotonic to the red blood cells. This means that the concentration of solute particles in the water is lower than that inside the red blood cells. If pure water is used instead, there would be a net movement of water into the red blood cells because water moves from hypotonic solutions to hypertonic solutions in order to equalize the concentration of solute particles.
As a result, if the 0.9% NaCl solution is replaced with pure water and left for some time, the red blood cells would undergo osmosis and swell up. This could potentially lead to the bursting of red blood cells, a process known as hemolysis.

Explanation:
The colligative properties of a given solution can be defined as the properties of that solution that are dependent on the concentration of the molecules or ions of the solute in the solution, and not on the type or identity of that solute. Examples include:
1. vapor pressure lowering
2. boiling point elevation
3. freezing point depression
4. Osmotic pressure
In this case, vapor pressure would be lowered because with an electrolyte introduced into a solution, the number of solute particles would be larger because the solute particles dissociate into ions, thereby competing with the solvent molecules at the surface of the solution, which in turn reduces the rate at which the solvent evaporates and condenses. Vapor pressure is lower compared to a solution with the same number of moles of nonelectrolyte solute.
The higher the number of ions in the solution, the greater the colligative properties of the solution will be impacted.
The presence of a strong electrolyte in solution affects the colligative properties differently than a non-electrolyte solute. Strong electrolytes dissociate into ions, increasing the number of particles in solution. This affects colligative properties such as vapor pressure, boiling point elevation, freezing point depression, and osmotic pressure.
The presence of a strong electrolyte in solution affects the colligative properties differently than the same number of moles of a non-electrolyte solute. This is because strong electrolytes dissociate into ions when dissolved in solution, while non-electrolytes do not. The dissociation of strong electrolytes increases the total number of particles in solution, which affects colligative properties such as vapor pressure, boiling point elevation, freezing point depression, and osmotic pressure.
For example, let's compare a solution of 1 mole of sodium chloride (NaCl) to a solution of 1 mole of sucrose (C12H22O11). The sodium chloride will dissociate into Na+ and Cl- ions, which means there are now 2 particles in solution (1 Na+ and 1 Cl-) instead of just 1 molecule of sucrose. This higher particle concentration will result in a greater depression of the freezing point and elevation of the boiling point compared to the sucrose solution.
In summary, the presence of a strong electrolyte increases the number of particles in solution, leading to greater deviations in colligative properties compared to the same number of moles of a non-electrolyte solute.
