A- the vapour pressure of toluene in solution is 4.98 kPa, B-the addition of C₆₀ to toluene causes a decrease in the chemical potential of toluene by approximately 13.6 J/mol.

a) The vapor pressure of the toluene solution can be calculated using Raoult's law:

mass of toluene = 100 g

molar mass of toluene = 92.14 g/mol

moles of toluene = 100 g / 92.14 g/mol = 1.085 mol

mass of C₆₀ = 2.33 g

molar mass of C₆₀ = 720.64 g/mol

moles of C₆₀ = 2.33 g / 720.64 g/mol = 0.00323 mol

total moles = 1.085 mol + 0.00323 mol = 1.088 mol

The mole fraction of toluene is therefore:

x(toluene) = 1.085 mol / 1.088 mol ≈ 0.997

The vapor pressure of the toluene solution can now be calculated using Raoult's law:

P(solution) = x(toluene) × P(toluene)

where P(toluene) is the vapor pressure of pure toluene at 30°C, which is given as 5 kPa. Therefore:

P(solution) = 0.997 × 5 kPa ≈ 4.98 kPa

b) The change in the chemical potential of toluene caused by the addition of C₆₀ can be calculated using the formula:

Δμ = RTln(γ₁/γ₁°)

Using the value of P(solution) calculated in part (a), we can calculate the activity of toluene in the solution:

P(solution) = x(toluene) × P(toluene) = 0.997 × 5 kPa ≈ 4.98 kPa

The activity coefficient of toluene in the solution can now be approximated as:

γ₁ = P(solution) / P(toluene) = 4.98 kPa / 5 kPa = 0.996

The change in chemical potential of toluene can now be calculated:

Δμ = RTln(γ₁/γ₁°) = (8.314 J/mol/K) × (303 K) × ln(0.996/1) ≈ -13.6 J/mol.

The statement that best describes the law of conservation of mass is "matter cannot be created or destroyed in a chemical reaction."

The law of conservation of mass, also known as the principle of mass conservation, states that the total mass of a closed system remains constant throughout any chemical reaction. This means that the mass of the reactants, which are the substances that undergo the reaction, must be equal to the mass of the products, which are the substances formed after the reaction.

Consequently, matter cannot be created or destroyed during a chemical reaction, and the total mass is conserved. The other statements provided do not accurately represent the law of conservation of mass, as they involve chemical symbols, closed systems, or the rearrangement of reactants, which are different aspects of chemical reactions.

To find the Br-Br bond energy, we need to use the bond energy values given in the table and apply Hess's law.

First, we need to write the balanced equation for the reaction:

H2(g) + Br2(g) → 2HBr(g)

Next, we can calculate the bond energies for the bonds broken and formed in the reaction:

Bonds broken:
1 mol H-H bonds x 435 kJ/mol = 435 kJ/mol
1 mol Br-Br bonds x ? kJ/mol = ? kJ/mol

Bonds formed:
2 mol H-Br bonds x 362 kJ/mol = 724 kJ/mol

Using Hess's law, we know that the sum of the bond energies for the bonds broken must equal the sum of the bond energies for the bonds formed plus the overall energy change for the reaction:

Bonds broken = Bonds formed + ΔH

Substituting in the bond energies we calculated and the given ΔH value of -36.44 kJ/mol:

435 kJ/mol + ? kJ/mol = 724 kJ/mol - 36.44 kJ/mol

Simplifying:

? kJ/mol = (724 kJ/mol - 435 kJ/mol) - (-36.44 kJ/mol)
? kJ/mol = 312.56 kJ/mol

Therefore, the Br-Br bond energy is approximately 313 kJ/mol or 313,000 J/mol.

The number of moles of water (H₂O) produced when 25.0 grams of C₂H₂ burns completely is 1.67 moles.

From the balanced chemical equation, we can see that for every 2 moles of C₂H₂ that react, 2 moles of H₂O are produced. Therefore, we can use the molar mass of C₂H₂ to calculate the number of moles of C₂H₂ that react, and then use stoichiometry to calculate the number of moles of H₂O produced.

Molar mass of C₂H₂ = 2(12.01 g/mol) + 2(1.008 g/mol) = 26.04 g/mol

Number of moles of C₂H₂ = mass/molar mass = 25.0 g / 26.04 g/mol = 0.960 moles

Using stoichiometry, we can see that 0.960 moles of C₂H₂ will produce 2 × 0.960 moles of H₂O:

Number of moles of H₂O produced = 2 × 0.960 moles = 1.67 moles

Therefore, when 25.0 grams of C₂H₂ burns completely, 1.67 moles of H₂O are produced.

When a helium-filled balloon is released, it rises up in the air due to the fact that helium is less dense than air. This is because helium atoms are much lighter than the molecules that make up the air we breathe.

Now, if we were to take an air-filled balloon and place it in a container filled with helium, the opposite effect would occur. Since air is denser than helium, the air-filled balloon would actually sink in the helium. This is because the buoyant force acting on the balloon is not strong enough to counteract the force of gravity pulling it down.

To understand this better, we need to look at the concept of buoyancy. Buoyancy is the upward force exerted by a fluid on an object immersed in it. This force is equal to the weight of the fluid displaced by the object. In the case of the helium-filled balloon, the weight of the displaced air is less than the weight of the helium in the balloon, resulting in a net upward force that allows it to float.

Sodium lactate is the salt of a weak acid (lactic acid) and a strong base (sodium hydroxide). The sodium ion has no effect on pH. Lactic acid dissociates as follows:

The Ka for lactic acid is 1.38 × 10^-4.

Since sodium lactate is a salt of the conjugate base, the lactate ion, we can assume that it hydrolyzes in water as follows:

CH3CH(OH)COO-(aq) + H2O(l) → CH3CH(OH)COOH(aq) + OH-(aq)

The Kb for lactate is Kw/Ka = 7.25 × 10^-10.

Now we can set up an ICE table to find the [OH^-] concentration:

| CH3CH(OH)COOH | OH^- | CH3CH(OH)COO^-

---|---|---|---

Initial Concentration | 0 | 0 | 0.25

Change | -x | +x | +x

Equilibrium Concentration | 0 - x | x | 0.25 + x

Kb = [CH3CH(OH)COOH][OH^-]/[CH3CH(OH)COO^-]

7.25 × 10^-10 = (x)(x)/(0.25 + x)

Since x is small compared to 0.25, we can assume that (0.25 + x) is approximately 0.25, and we can simplify the equation to:

7.25 × 10^-10 = x^2/0.25

x = 2.14 × 10^-6 M

So, [OH^-] = 2.14 × 10^-6 M

pOH = -log[OH^-] = -log(2.14 × 10^-6) = 5.67

What is the amount of energy evolved during the reaction of 32.5 g [tex]B_{2}H_{6}[/tex] and 72.5 g [tex]Cl_{2}[/tex]?

To determine the amount of energy evolved during the reaction of 32.5 g [tex]B_{2}H_{6}[/tex] and 72.5 g [tex]Cl_{2}[/tex], we need to first determine which reactant is limiting.

First, we need to convert the mass of [tex]B_{2}H_{6}[/tex] into moles:

32.5 g B2H6 ÷ 27.67 g/mol = 1.175 mol [tex]B_{2}H_{6}[/tex]

Next, we need to convert the mass of [tex]Cl_{2}[/tex] into moles:

72.5 g Cl2 ÷ 70.90 g/mol = 1.023 mol Cl2

The stoichiometric ratio between [tex]B_{2}H_{6}[/tex] and [tex]Cl_{2}[/tex] is 1:6, meaning that for every 1 mole of [tex]B_{2}H_{6}[/tex], 6 moles of [tex]Cl_{2}[/tex] are required for complete reaction. Therefore, [tex]Cl_{2}[/tex] is the limiting reagent because there are only 1.023 mol of [tex]Cl_{2}[/tex] available, while 1.175 mol of [tex]B_{2}H_{6}[/tex] are present.

Now that we know [tex]Cl_{2}[/tex] is the limiting reagent, we can use its amount to calculate the amount of energy evolved during the reaction. From the balanced equation, we see that the molar ratio between [tex]B_{2}H_{6}[/tex] and ΔrH° is 1/2, meaning that for every 2 moles of [tex]BCl_{3}[/tex] produced, 1 mole of energy is released.

The amount of [tex]BCl_{3}[/tex] produced from the reaction of 1.023 mol of [tex]Cl_{2}[/tex] is:

(1.023 mol [tex]Cl_{2}[/tex]) x (2 mol [tex]BCl_{3}[/tex] / 6 mol [tex]Cl_{2}[/tex]) = 0.341 mol [tex]BCl_{3}[/tex]

Therefore, the amount of energy evolved from the reaction is:

ΔrH° x n = (-1396 kJ/mol) x (0.341 mol) = -475.24 kJ

So, the energy evolved during the reaction of 32.5 g [tex]B_{2}H_{6}[/tex] and 72.5 g [tex]Cl_{2}[/tex] is -475.24 kJ.

D) An electron. Gamma decay is a type of radioactive decay in which an atomic nucleus emits gamma rays, which are high-energy electromagnetic radiation.

Nucleus is an organelle found in eukaryotic cells that serves as the control center of the cell. It is the most important organelle in the cell as it contains the genetic material of the cell. The nucleus houses the chromosomes in a liquid called the nucleoplasm, which is surrounded by a nuclear membrane. This membrane is composed of proteins and lipids, and it helps to keep the genetic material within the nucleus separated from the rest of the cell.

Gamma decay typically occurs during the transition of an atom from a high-energy state to a lower-energy state. The decaying nucleus emits an electron, which carries the energy away from the nucleus and results in the transition to the lower-energy state.

Therefore the correct option is D.
