Filtration is a basic process for removing solid particles suspended in a liquid solution. Filtration is a method of separating solids from liquids or gases by employing a filter material that enables the fluid but not the solid to pass through. A funnel with filter paper can be used to gather solid product during the filtration process.

Explanation:
a. What effect does adding a solute to a solvent have on the freezing point of the solvent? What equation describes the effect? b. What effect does adding a solute to a solvent have on the boiling point of the solvent? What equation describes the effect?
Answers
Answer:
a. Adding a solute to a solvent results in freezing point depression that is lowering of the freezing point of the solvent
The equation that describes the effect is [tex]\Delta T_f = K_f \times m \times i[/tex]
b. The effect of adding a solute to a solvent have on the boiling point of the solvent is the elevation of the boiling point of the solvent
The equation that describes the effect of boiling point elevation is given as follows;
[tex]\Delta T_b = K_b \times m \times i[/tex]
Explanation:
[tex]\Delta T_f = K_f \times m \times i[/tex]
Where:
[tex]\Delta T_f[/tex] = [tex]T_{f(pure \ solvent)}[/tex] - [tex]T_{f(solution)}[/tex]
[tex]K_f[/tex] = Constant for Molal freezing point
i = van't Hoff factor which is the number of irons present in each solute molecule
m = Molality of the solution
[tex]\Delta T_b = K_b \times m \times i[/tex]
Where:
[tex]\Delta T_b[/tex] = [tex]T_{f(pure \ solvent)}[/tex] - [tex]T_{f(solution)}[/tex]
[tex]K_b[/tex] = Constant for Molal freezing point
i = van't Hoff factor which is the number of irons present in each solute molecule
m = Molality of the solution
Adding a solute to a solvent affects the freezing point and boiling point of the solvent by either lowering or raising them, respectively. These effects can be described using the freezing point depression and boiling point elevation equations, which take into account the molality of the solute and the constants specific to each solvent.
a. When a solute is added to a solvent, it lowers the freezing point of the solvent. This phenomenon is known as freezing point depression. The equation that describes the effect is the freezing point depression equation:
∆T = Kf * m
where ∆T is the change in freezing point, Kf is the cryoscopic constant, and m is the molality of the solute.
To explain this further, when a solute is added to a solvent, it disrupts the regular arrangement of solvent molecules in the crystal lattice during freezing. This makes it more difficult for the solvent to form a solid, resulting in a decrease in the freezing point.
For example, if you add salt (NaCl) to water, the salt molecules will mix with the water molecules. As a result, the freezing point of the water will decrease, and it will require a lower temperature for the water to freeze.
b. Adding a solute to a solvent also raises the boiling point of the solvent. This is known as boiling point elevation. The equation that describes the effect is the boiling point elevation equation:
∆T = Kb * m
where ∆T is the change in boiling point, Kb is the ebullioscopic constant, and m is the molality of the solute.
To understand this concept, when a solute is added to a solvent, the solute particles disrupt the intermolecular forces between solvent molecules. This increases the boiling point of the solution because more heat energy is required to overcome the stronger intermolecular forces between the solute and solvent particles.
For instance, if you dissolve sugar (C12H22O11) in water, the sugar molecules will interact with the water molecules. As a result, the boiling point of the water will increase, and it will require a higher temperature for the water to boil.

If 1 atom of sulfur combines with 2 atoms of oxygen to form sulfur dioxide, what is the ratio of mass of sulfur atom to mass of oxygen atom in sulfur dioxide?
Answers
Answer: The ratio of mass of sulfur atom to mass of oxygen atom in sulfur dioxide is 1: 1.
Explanation:
Law of constant proportion states that In a chemical substance the elements are always present in definite proportions by mass. This law is also known as 'Law of definite proportions '.
Mass of 1 atom of sulphur = 32 g
Mass of 1 atom of oxygen = 16 g
Mass of 2 atoms of oxygen =[tex]16g\times 2=32g[/tex]
In formation of [tex]SO_2[/tex] , 1 atom of sulfur combines with 2 atoms of oxygen and thus the mass ratio will be 32: 32= 1:1 .
Thus the ratio of mass of sulfur atom to mass of oxygen atom in sulfur dioxide is 1: 1.

Calculate the number of grams of HNO3 which must be added to 31.5 g of H20 to prepare a 0.950 m solution.
Answers
Answer:
1.89g of HNO3
Explanation:
Data obtained from the question include:
Mass of water = 31.5 g
Molality of HNO3 = 0.950 m
Mass of HNO3 =.?
Next, we shall determine the number of mole of HNO3 in the solution.
Mass of water = 31.5 g = 31.5/1000 = 0.0315 Kg
Molality of HNO3 = 0.950 m
Number of mole of HNO3 =..?
Molality is simply defined as the mole of solute per unit kilogram of solvent (water) i.e
Molality = mole /kg of water
With the above formula, the mole of HNO3 can be obtained as follow:
Molality = mole /kg of water
0.950 = mole of HNO3 /0.0315
Cross multiply
Mole of HNO3 = 0.950 x 0.0315
Mole of HNO3 = 0.03 mole
Finally, we shall convert 0.03 mole of HNO3 to grams. This is illustrated below:
Molar mass of HNO3 = 1 + 14 + (16x3) = 63g/mol
Mole of HNO3 = 0.03 mole
Mass of HNO3 =..?
Mole = mass /molar mass
0.03 = mass of HNO3 /63
Cross multiply
Mass of HNO3 = 0.03 x 63
Mass of HNO3 = 1.89g
Therefore, 1.89g of HNO3 is needed to prepare the solution.
how does the vapor pressure of water at 10°C compared with its vapor pressure at 50°C ?
Answers
Answer: The vapor pressure of water at 10°C will be less as compared with its vapor pressure at 50°C.
Explanation:
Vapor pressure of a liquid is defined as the pressure exerted by the vapors in equilibrium with the liquid/solution at a particular temperature.
As Kinetic energy is dependent on the absolute temperature of the gas.
[tex]K.E=\frac{3}{2}RT[/tex]
where R = gas constant
T = temperature
On increase in temperature, the kinetic energy of the molecules increase and thus more liquid molecules can escape to form vapours and thus will exert more vapor pressure.
Thus the vapor pressure of water at 10°C will be less as compared with its vapor pressure at 50°C.

Answers
Answer:
The gas cloud must be very dense.Temperatures must exceed 14 million Kelvin
Nuclear fusion is the process in which atomic nuclei come together to form heavier nuclei, releasing large amounts of energy in the process. The correct statements are The gas cloud must be very dense, Atoms must be stripped of their electrons, and Temperatures must exceed 14 million Kelvin.
For fusion to occur, certain conditions must be met. The gas cloud or plasma must be dense enough to allow for a sufficient number of collisions between atomic nuclei. Gravitational attraction, on the other hand, is necessary to bring the atomic nuclei close enough together for the strong nuclear force to overcome the electrostatic repulsion between positively charged nuclei.
Atoms must be stripped of their electrons because, in a plasma state, the atoms are ionized, meaning they have lost or gained electrons and exist as charged particles.
Hence, the correct statements are The gas cloud must be very dense, Atoms must be stripped of their electrons, and Temperatures must exceed 14 million Kelvin.

A) The rate decreases because a higher temperature means that particles move at higher speeds and there are more collisions in the system. B) The rate decreases because a higher temperature means that particles move at lower speeds and there are fewer collisions in the system. C) The rate increases because a higher temperature means that particles move at lower speeds and there are fewer collisions in the system. D) The rate increases because a higher temperature means that particles move at higher speeds and there are more collisions in the system.
Answers
Answer:
D). The rate increases because a higher temperature means that particles move at higher speeds and there are more collisions in the system.
Explanation:
The rate of the given chemical reaction would rapidly increase with an increase in temperature as the higher temperature will increase the kinetic energy possessed by the reactant molecules. This will lead to the movement of particles at a higher speed and more effective collisions will take place(as the greater proportion of molecules will have the energy required for collision). Thus, the last statement correctly justifies this description and hence, option D is the correct answer.
