When CO₂ is heated from 15°C to 37°C, its molar internal energy changes by 2446.2 J/mol, as does its molar enthalpy.

The following equation can be used to determine how carbon dioxide (CO₂) will change in molar enthalpy and molar internal energy when heated from 15 to 37 degrees Celsius:

ΔH = ΔU + ΔnRT

ΔU = nCvΔT

where:

ΔH = change in molar enthalpy of CO₂ (in J/mol)

ΔU = change in molar internal energy of CO₂ (in J/mol)

Δn = change in moles of CO₂ (in mol)

R = universal gas constant (8.314 J/(mol·K))

T = temperature (in K)

Cv = molar heat capacity at constant volume (in J/(mol·K))

ΔT = change in temperature (in K)

First, let's calculate the change in temperature:

ΔT = T2 - T1

= (37 + 273.15) K - (15 + 273.15) K

= 22 K

Next, let's calculate the change in molar internal energy:

ΔU = nCvΔT

= 3 mol × 37.1 J/(mol·K) × 22 K

= 2446.2 J/mol

Now, let's calculate the change in molar enthalpy using the equation:

ΔH = ΔU + ΔnRT

where Δn = 0 because the number of moles of CO₂ does not change during heating. Therefore:

ΔH = ΔU + ΔnRT

= 2446.2 J/mol + 0 mol × 8.314 J/(mol·K) × (37 + 273.15) K

= 2446.2 J/mol

To calculate the mass of mercury(I) chloride that the chemist has added to the reaction flask, we need to know the molar mass of the compound and the number of moles of the solution added.

The molar mass of mercury(I) chloride is 232.6 g/mol. The chemist added an unspecified volume of the solution, so we cannot directly calculate the number of moles added. However, we can use the concentration of the solution, which is typically given in units of moles per liter (mol/L).

Let's assume that the concentration of the mercury(I) chloride solution is 0.1 mol/L. This means that there are 0.1 moles of mercury(I) chloride in every liter of the solution. We don't know how much of the solution the chemist added, but we can use a conversion factor to calculate the number of moles based on the volume.

For example, if the chemist added 10 mL of the solution, we can convert that to liters by dividing by 1000 (1 mL = 0.001 L).
10 mL x (0.001 L/1 mL) = 0.01 L
Now we can use the concentration to calculate the number of moles:

0.1 mol/L x 0.01 L = 0.001 mol
Finally, we can use the molar mass to convert from moles to grams:
0.001 mol x 232.6 g/mol = 0.2326 g

To convert to micrograms, we need to multiply by 1,000,000:
0.2326 g x 1,000,000 µg/g = 232,600 µg
Therefore, the mass of mercury(I) chloride added to the reaction flask is 232,600 µg, rounded to significant digits.

It's worth noting that the exact answer will depend on the actual concentration of the solution and the volume added, but this calculation provides a general approach to solving this type of problem.

To find the concentration of H₂SO₄ solution used by Erica, we can use the concept of stoichiometry and the balanced chemical equation for the neutralization reaction between KOH and H₂SO₄:

KOH + H₂SO₄ -> K₂SO₄ + 2H2O

From the balanced equation, we can see that the mole ratio of KOH to H₂SO₄ is 1:1. This means that the number of moles of H₂SO₄ used in the reaction is equal to the number of moles of KOH. We can use this fact to calculate the number of moles of H₂SO₄ used:

moles of KOH = volume of KOH solution (in L) x concentration of KOH solution
moles of KOH = 80.0 mL x (1 L/1000 mL) x 0.70 mol/L = 0.056 mol

Since the mole ratio of KOH to H₂SO₄ is 1:1, the number of moles of H₂SO₄ used is also 0.056 mol. Now we can use the same formula as above to calculate the concentration of H₂SO₄:

concentration of H₂SO₄ = moles of H2SO4 / volume of H₂SO₄ solution (in L)
concentration of H₂SO₄ = 0.056 mol / (28.0 mL x 1 L/1000 mL) = 2.00 mol/L

The standard cell potential (∆°cell) can be calculated using the formula:

∆°cell = ∆°reduction (reduced) - ∆°oxidation (oxidized)

where ∆°reduction and ∆°oxidation are the standard reduction potentials of the reduction and oxidation half-reactions, respectively.

The oxidation half-reaction is:

Ni2+(aq) + 2e- → Ni(s) ∆°oxidation = - 0.26 V

The reduction half-reaction is:

Mg2+(aq) + 2e- → Mg(s) ∆°reduction = - 2.37 V

Therefore, the standard cell potential is:

∆°cell = ∆°reduction - ∆°oxidation

∆°cell = (-2.37 V) - (-0.26 V)

∆°cell = -2.11 V

The equilibrium constant (K) can be calculated from the standard cell potential using the Nernst equation:

∆°cell = -(RT/nF) ln K

where R is the gas constant (8.314 J/(mol·K)), T is the temperature in Kelvin (298 K), n is the number of electrons transferred in the balanced equation (2), and F is the Faraday constant (96,485 C/mol).

Substituting the values and solving for K, we get:

K = exp(-(∆°cell)/(RT/nF))

K = exp(-((-2.11 V)*(96,485 C/mol)/(8.314 J/(mol·K)298 K2)))

K = 1.1 × 10^12

The solubility is the amount of a substance that dissolves in a given quantity of solvent at a particular temperature to produce a saturated solution.

Definition: Solubility is defined as the maximum amount of solute that can dissolve in a given quantity of solvent at a specific temperature and pressure to form a saturated solution. It is typically expressed in terms of the mass of solute per unit volume or mass of solvent.

Solute and Solvent: In a solution, the solute is the substance that is being dissolved, while the solvent is the medium in which the solute dissolves. The solute can be a solid, liquid, or gas, while the solvent is usually a liquid, but can also be a gas or a solid in some cases.

Saturated Solution: A saturated solution is a solution in which the maximum amount of solute has been dissolved in a given quantity of solvent at a specific temperature. In a saturated solution, the rate of dissolution of the solute is balanced by the rate of precipitation or crystallization of the solute, resulting in a dynamic equilibrium.

Factors Affecting Solubility: The solubility of a solute depends on several factors, including temperature, pressure, and the nature of the solute and solvent.

Generally, increasing temperature enhances solubility for most solid solutes, while the effect of pressure on solubility is more significant for gases dissolved in liquids. The polarity and intermolecular forces between the solute and solvent molecules also influence solubility.

Solubility Curves: Solubility can be represented graphically by constructing solubility curves. These curves depict the relationship between the solute's solubility and the temperature or pressure.

Solubility curves can help determine the maximum amount of solute that can dissolve under different conditions and can vary for different solutes and solvents.

Supersaturation: Under certain conditions, it is possible to create a supersaturated solution, where the solute concentration exceeds the solubility limit at a given temperature.

Supersaturated solutions are unstable and can result in the precipitation of excess solute upon the introduction of a seed crystal or disturbance.

where P1 is the initial pressure, V1 is the initial volume, T1 is the initial temperature, P2 is the final pressure, V2 is the final volume, and T2 is the final temperature.

In this problem, we are given the initial volume V1 as 2.32 liters and the initial temperature T1 as 24.0°C. We need to find the final volume V2 when the temperature is raised to 48.0°C.

We can set up the equation as:

(P1V1)/T1 = (P2V2)/T2

Since the pressure remains constant, we can cancel it out:

V1/T1 = V2/T2

We can rearrange this equation to solve for V2:

V2 = (V1/T1) x T2

Substituting the given values, we get:

V2 = (2.32 L/297.15 K) x 321.15 K

The boiling point of the solution is 80.58 °C, which is prepared by dissolving 2. 50 g of biphenyl (C₁₂ H₁₀).

To determine the boiling point of the solution, we need to use the equation;

Δ[tex]T_b}[/tex] = [tex]K_{b}[/tex] x m

Where ΔTb is boiling point elevation, is molal boiling point elevation constant, and m is molality of the solution.

First, we to calculate the molality of the solution;

moles of biphenyl =2.50 g / 154 g/mol

= 0.0162 mol

mass of benzene = 85.0 g

moles of benzene = 85.0 g / 78.11 g/mol

= 1.088 mol

molality = moles of solute/mass of solvent (in kg)

molality = 0.0162 mol / 0.085 kg

= 0.19 mol/kg

Next, we need to look up the molal boiling point elevation constant ([tex]K_{b}[/tex]) for benzene. The value of [tex]K_{b}[/tex] for benzene is 2.53 °C/m.

Finally, we alculate the boiling point elevation;

Δ[tex]T_b}[/tex] = [tex]K_{b}[/tex] x m

Δ[tex]T_b}[/tex] = 2.53 °C/m x 0.19 mol/kg

= 0.481 °C

The boiling point elevation (Δ[tex]T_b}[/tex]) is the difference between the boiling point of the solution and the boiling point of the pure solvent. The boiling point of pure benzene is 80.1 °C. Therefore, the boiling point of the solution will be;

Boiling point of solution = 80.1 °C + 0.481 °C

= 80.58 °C

So, the boiling point of the solution is 80.58 °C.

[tex]3 H_2SO_4 + Al_2(SO_4)_3[/tex]  → [tex]Al_2(SO_4)_3 + 3 H_2O[/tex]

From the equation, we can see that for every one mole of the [tex]Al_2(SO_4)_3[/tex] produced, three moles of [tex]H_2SO_4[/tex] are needed. Therefore, the number of moles of the [tex]Al_2(SO_4)_3[/tex]produced is one-third the number of moles of the [tex]H_2SO_4[/tex] available to react.

Given that 8.5 moles of [tex]H_2SO_4[/tex] are available to react, the number of moles of [tex]Al_2(SO_4)_3[/tex] produced can be calculated as:

8.5 moles [tex]H_2SO_4[/tex] × (1 mole [tex]Al_2(SO_4)_3[/tex] / 3 moles [tex]H_2SO_4[/tex]) = 2.83 moles [tex]Al_2(SO_4)_3[/tex]
