The [OH⁻] of the solution is 4.93 x 10⁻³ M. The balanced chemical equation for the reaction between CO₃²⁻ and water is:CO₃²⁻ + H₂O → HCO₃⁻ + OH⁻

We know that the Kb for CO₃²⁻ is 1.8 x 10⁻⁴. Therefore, we can calculate the [OH⁻] using the following expression: Kb = [HCO₃⁻][OH⁻] / [CO₃²⁻]Kb = x² / (0.135-x).

We can assume that the value of "x" is negligible compared to 0.135. Therefore, we can simplify the expression as follows: Kb = x² / (0.135)Solving for "x", we get:x² = Kb * 0.135x² = 1.8 x 10⁻⁴ * 0.135x₂ = 2.43 x 10⁻⁵ x = 4.93 x 10⁻³ M

Valence bond theory is one of the various theories used to describe how chemical bonding occurs. It is based on the idea that the formation of chemical bonds occurs as a result of the overlap between atomic orbitals in the valence shell. In the case of sulfur dioxide, SO2, valence bond theory predicts that sulfur will use three hybrid orbitals.

In the case of sulfur dioxide, SO2, valence bond theory predicts that sulfur will use three hybrid orbitals. It is because sulfur has six valence electrons. The hybridization of the orbitals takes place so that they can have the same energy, shape, and orientation for proper overlap. These orbitals combine to form a set of three hybrid orbitals. The valence bond theory is useful in understanding how chemical bonds are formed and how they affect the properties of molecules. It is widely used in the field of chemistry to explain the behavior of molecules and the reactions they undergo.

At 25 °C, the equilibrium constant (Kc) for the reaction Mg(s) + Pb2+(aq) ⇌ Mg2+(aq) + Pb(s) is approximately 2.26 × 10⁻¹³.

To calculate the equilibrium constant, Kc, for the given reaction at 25 °C:

Mg(s) + Pb2+(aq) ⇌ Mg2+(aq) + Pb(s)

We can use the following equilibrium constant expression:

Kc = [Mg2+(aq)][Pb(s)] / [Mg(s)][Pb2+(aq)]

However, since the reaction involves solid species, we cannot directly determine the concentrations. Instead, we can utilize the Nernst equation and the standard reduction potentials (E°) of the half-reactions involved.

The half-reactions have associated standard reduction potentials, which indicate the tendency of a species to gain electrons and undergo reduction.

Mg2+(aq) + 2e- ⇌ Mg(s) E° = -2.37 V

Pb2+(aq) + 2e- ⇌ Pb(s) E° = -0.13 V

We can calculate the E°cell, the standard cell potential, using the formula:

E°cell = E°cathode – E°anode

E°cell = E°Pb(s) – E°Mg(s) = (-0.13 V) – (-2.37 V) = 2.24 V

To determine Kc, we use the relationship:

Kc = e^(-nE°cell/RT)

where n is the number of moles of electrons transferred in the balanced equation, R is the universal gas constant (8.314 J/(mol·K)), and T is the temperature in Kelvin.

For this reaction, n = 2 (from the two half-reactions) and T = 298 K.

replacing the terms with corresponding values,

Kc = e^(-2 * 2.24 * 96500 / (8.314 * 298)) ≈ 2.26 × 10⁻¹³

Therefore, at 25 °C, the equilibrium constant (Kc) for the reaction Mg(s) + Pb2+(aq) ⇌ Mg2+(aq) + Pb(s) is approximately 2.26 × 10⁻¹³.

The arrangement which shows the species in order of increasing stability is : B) Li₂⁻ < Li₂ = Li₂⁻. Hence, option B) is the correct answer.

Stability is the ability of a molecule or ion to persist indefinitely under specific circumstances without falling apart into other species. Stability increases when a molecule becomes more ordered and structured. This relates to intermolecular forces, which are strong in highly ordered and structured molecules.

Based on the data in the given equation, we can say that the species with the lowest level of stability is Li₂ while the Li₂⁻ ion is the most stable. Li₂ is the least stable of the three species listed because it is a neutral molecule and its bonding is not ionically, which means it is held together by weak London dispersion forces. Li₂ is more stable than Li⁻ because it is a neutral molecule, which means it does not have the added stability of a negative charge.

Li₂⁻ is the most stable of the three species because it has the lowest energy and highest stability due to the charge on the molecule, which holds the atoms together more tightly than in Li₂.  Hence, the correct order of increasing stability is Li₂⁻ < Li₂ = Li₂⁻.

Answer: A

Explanation: A

The value of ∆g° for a reaction when ∆g = -138.2 kJ/mol and q = 0.043 at 298 K is -150 kJ/mol.

We can use the given information to calculate the ∆g° for the reaction using the equation;

∆g° = -RT ln(K)

where K is the equilibrium constant and R is the gas constant.

K can be calculated as; K = q/n

where q is the reaction quotient and n is the stoichiometric coefficient of the reaction.

Let's start by finding n. Since we are not given the reaction, let's assume a general reaction;

aA + bB ⇌ cC + dD

We can say that;

n = c + d - (a + b)

To calculate K, we need to know the concentrations of all species present at equilibrium. Since we are not given any concentrations, we can use the following relation;

q = Kc

where c is the concentration at equilibrium in mol/L.

If we assume that the initial concentration of all species is 1 M, we can say that;

c = [C]^c[D]^d/[A]^a[B]^bAt equilibrium,

we know that;

c = 1 + cεd = 1 + dεa = 1 - aεb = 1 - bε

where ε is the extent of the reaction.

To find ε, we can use the following relation;

ε = (n/V)Q

where V is the total volume of the system at equilibrium and Q is the reaction quotient.

Substituting the values given;

ε = (n/V)qε = (c + d - a - b)q/Vε = (c + d - a - b)/(a + b + c + d)q

Since V = 1 L and all species have the same initial concentration, we have;

c = 1 + cq = Kc = K(1 + c)^c(1 + d)^d(1 - a)^a(1 - b)^b

Substituting the expressions for c, d, a, b and q;

K = (1 + cq)^-1(c + d - a - b)/(a + b + c + d)

This gives us the value of K.

We can now use this value to find ∆g°;

∆g° = -RT ln(K)∆g° = -8.314 J/mol K × 298 K × ln(K)/1000

∆g° = -RT ln(K) is the same as ∆g° = -2.303 RT log(K)

Substituting the values given, we have;

∆g° = -2.303 × 8.314 J/mol K × 298 K × log(K)/1000∆g°

    = -2.303 × 8.314 J/mol K × 298 K × log[(1 + 0.043)^0.043(1 + 0.043)^0.043(1 - 0.043)^0.043(1 - 0.043)^0.043]/1000∆g°                 =-150 kJ/mol

the cell potential (Ecell) for the given cell is +0.94 V.

To find the cell potential of the given cell, we can use the standard reduction potentials (E°) from a standard reduction table. The cell potential (Ecell) can be calculated by subtracting the reduction potential of the anode (oxidation half-reaction) from the reduction potential of the cathode (reduction half-reaction).

Given the half-reactions:

Anode (oxidation half-reaction): Sn (s) → Sn2+ (aq) + 2e-

Cathode (reduction half-reaction): 2Ag+ (aq) + 2e- → 2Ag (aq)

The standard reduction potentials (E°) for these half-reactions can be found in a standard reduction table. Let's assume the values are as follows:

E° for Sn2+ (aq) + 2e- → Sn (s) = -0.14 V

E° for 2Ag+ (aq) + 2e- → 2Ag (aq) = +0.80 V

To calculate the cell potential (Ecell), we subtract the anode reduction potential from the cathode reduction potential:

Ecell = E°cathode - E°anode

Ecell = (+0.80 V) - (-0.14 V)

Ecell = +0.94 V

According to the given question, the correct statement is "Work was done by the system," as the system performed work by using some of the heat gained to do work, resulting in the change in internal energy.
To solve this problem, we can use the first law of thermodynamics, which states:

ΔU = Q - W

where U is the change in internal energy, Q is the heat added to the system, and W is the work done by the system.

In this case, the system gains 722 kJ of heat (Q = 722 kJ), and the change in internal energy is +211 kJ (U = 211 kJ). We need to find the work done (W).

Plugging in the values, we have:

211 kJ = 722 kJ - W

Now, rearrange the equation to solve for W:

W = 722 kJ - 211 kJ

W = 511 kJ

So, the work done is 511 kJ. Since W is positive, this means work was done by the system.

In conclusion, 511 kJ of work is done by the system.

In order to balance the chemical equation 32 + xH2 → y(H)2 + zH3, we need 32 moles of hydrogen gas (H2), x = 16 moles of H2, y = 32 moles of H, and z = 16 moles of H3.

To balance a chemical equation, we need to ensure that the number of atoms on both sides of the equation is equal. In this case, we have 32 hydrogen atoms (H) on the left side, represented by xH2, and we need to determine the values of x, y, and z to balance the equation.

On the right side, we have y(H)2, which means we have 2y hydrogen atoms. Similarly, we have zH3, which represents 3z hydrogen atoms.

To balance the equation, we need to find values for x, y, and z that satisfy the condition. Since we have 32 hydrogen atoms on the left side, we can set up the equation:

2y + 3z = 32

To simplify the equation, we can divide both sides by the greatest common divisor of 2 and 3, which is 1. This gives us:

2y + 3z = 32

To find a solution for this equation, we can try different values for y and z that satisfy the equation. After some trial and error, we find that y = 32 and z = 16 satisfy the equation.

Therefore, the balanced chemical equation is:

32 + 16H2 → 32(H)2 + 16H3

The statement that best describes the Heisenberg uncertainty principle is that it is impossible to accurately know both the exact location and momentum of a particle.

What is the Heisenberg uncertainty principle? The Heisenberg uncertainty principle, named after Werner Heisenberg, is a principle in quantum mechanics that states that it is impossible to accurately determine the exact position and momentum of a particle simultaneously. Heisenberg's uncertainty principle states that the more precisely we measure a particle's position, the less precise our measurement of its momentum will be.

The principle's importance lies in its influence on quantum mechanics' theoretical framework, which is a fundamental theory of modern physics. This principle is also fundamental in determining the behavior of the microscopic world, where classical mechanics laws fail to apply correctly. In general, this principle applies to all waves, including sound and light waves, as well as matter, including electrons and atoms. Hence, it is impossible to accurately know both the exact location and momentum of a particle.
