The relative rates of solvolysis via an SN1 mechanism are determined by both the stability of the carbocation intermediate and the nature of the leaving group.

The relative rates of solvolysis through an SN1 mechanism are primarily determined by the stability of the intermediate carbocation formed during the reaction. More stable carbocations are formed more easily, which results in faster reaction rates.

In general, tertiary alkyl halides form more stable carbocations compared to secondary or primary alkyl halides. This is due to the increased number of alkyl groups attached to the carbon bearing the leaving group.

The electron-donating effect of these groups leads to greater positive charge delocalization, which stabilizes the carbocation intermediate.

Therefore, tertiary alkyl halides will generally have the fastest rates of solvolysis via an SN1 mechanism, followed by secondary and primary alkyl halides. This trend is consistent with experimental data.

Additionally, the nature of the leaving group also plays a role in the rate of solvolysis. Leaving groups that are better able to stabilize negative charge, such as iodide, tend to promote faster reaction rates compared to leaving groups that are weaker in this regard, such as bromide or chloride.

The ideal gas law, which connects a gas's pressure, volume, number of moles, and temperature, can be used to address this issue:

PV = nRT

when the gas constant R is used. To solve for pressure, we may rearrange this equation as follows:

P = nRT/V

Then, using the molar mass of the gas, we must determine how many moles there are of O2:

O2 mass divided by its molar mass yields moles.

O2's molar mass is 32 g/mol (from periodic table)

14.4 g / 32 g/mol = 0.45 mol for moles of oxygen

The ideal gas law equation can then be changed to include the given values:

P = nRT/V

P = (0.45 mol)(0.0821 L·atm/mol·K)(375 K)/(7.5 L)

P = 16.6 atm

Therefore, at a temperature of 375K, 14.4g of O2 gas would occupy 7.5L at a pressure of approximately 16.6 atm.

The voltage follower typically has a voltage gain value of A) 1.

The voltage follower is an operational amplifier circuit configuration that has a voltage gain of approximately 1. It is designed to provide unity gain, meaning that the output voltage follows the input voltage without amplification or attenuation.

The voltage follower is commonly used in circuits where a high input impedance is required, or when the input signal needs to be isolated from the load. It is also used in applications where a low output impedance is desired, as it can provide a high current output without affecting the input signal. The voltage follower is a simple circuit that consists of an op-amp with a feedback loop connected from the output to the inverting input. This feedback loop ensures that the output voltage is equal to the input voltage, resulting in a gain of 1.

(a) When the density of gold is 19.32 g/\(cm^{3}\) than area of the gold leaf is approximately 0.4386 cm².

(b) The length of the gold fiber is given by h = 0.4386 cm³ / (π * (2.500 × 10⁻⁴ cm)²).

To solve these problems, we can use the formula for the volume of a shape and the given density of gold.

(a) To find the area of the leaf, we can use the formula for the volume of a rectangular shape: V = A * h, where V is the volume, A is the area, and h is the thickness.

Given the mass of gold (m = 8.489 g) and density (ρ = 19.32 g/cm³), we can find the volume: V = m / ρ.

Substituting the values, we have V = 8.489 g / 19.32 g/cm³ = 0.4386 cm³.

Since the leaf is pressed into a thin shape, we can assume it has a rectangular shape, and the volume is approximately equal to the area: A ≈ V = 0.4386 cm².

(b) To find the length of the fiber, we can use the formula for the volume of a cylindrical shape: V = π * r² * h, where V is the volume, r is the radius, and h is the length.

Given the mass of gold (m = 8.489 g) and density (ρ = 19.32 g/cm³), we can find the volume: V = m / ρ.

Substituting the values, we have V = 8.489 g / 19.32 g/cm³ = 0.4386 cm³.

The volume of a cylinder is also equal to the product of the cross-sectional area (π * r²) and the length (h), so we have: π * r² * h = 0.4386 cm³.

Substituting the radius (r = 2.500 μm = 2.500 × 10⁻⁴ cm), we can solve for the length: h = 0.4386 cm³ / (π * (2.500 × 10⁻⁴ cm)²).

To summarize:

(a) The area of the gold leaf is approximately 0.4386 cm².

(b) The length of the gold fiber is given by h = 0.4386 cm³ / (π * (2.500 × 10⁻⁴ cm)²).

a) The sphere emits thermal radiation at a rate of 139.75 Watts.

b) The sphere absorbs thermal radiation at a rate of 37.66 Watts.

c) The sphere's net rate of energy exchange is 102.09 Watts.

To calculate the rates of thermal radiation emission and absorption, we can use the Stefan-Boltzmann law, which states that the rate of thermal radiation emitted or absorbed by an object is proportional to its surface area, temperature, and the Stefan-Boltzmann constant.

a) The rate of thermal radiation emitted by the sphere can be calculated using the formula:

Emitting Rate = emissivity * surface area * Stefan-Boltzmann constant * (\(temperature^4 - environment\ temperature^4\))

Plugging in the given values:

Emitting Rate = \(0.924 * (4\pi * (0.457)^2) * 5.67 \times 10^{-8} * ((32.2 + 273.15)^4 - (82.9 + 273.15)^4)\)

Emitting Rate ≈ 139.75 Watts

b) The rate of thermal radiation absorbed by the sphere can be calculated in a similar way but using the environment temperature as the object's temperature:

Absorbing Rate = emissivity * surface area * Stefan-Boltzmann constant * (\(environment\ temperature^4 - temperature^4\))

Plugging in the given values:

Absorbing Rate = \(0.924 * (4\pi * (0.457)^2) * 5.67 \times 10^{-8} * ((82.9 + 273.15)^4 - (32.2 + 273.15)^4)\)

Absorbing Rate ≈ 37.66 Watts

c) The net rate of energy exchange is the difference between the emitting rate and the absorbing rate:

Net Rate = Emitting Rate - Absorbing Rate

Net Rate = 139.75 Watts - 37.66 Watts

Net Rate ≈ 102.09 Watts

Therefore, the sphere emits thermal radiation at a rate of 139.75 Watts, absorbs thermal radiation at a rate of 37.66 Watts, and has a net rate of energy exchange of 102.09 Watts.

Note: The units for all the rates are Watts.

Answer:

B.) Na₂SO₄

Explanation:

Covalent bonds are bonds which involve electrons being shared between two atoms. These bonds only occur between nonmetals.

Ionic bonds are bonds which involve electrons being given or taken by two atoms. These bonds form between a metal and a nonmetal.

NH₃ contains nitrogen and hydrogen, two nonmetals. Therefore, this molecule only contains covalent bonds.

Na₂SO₄ has both covalent and ionic bonds. The covalent bonds are found within the polyatomic ion, SO₄²⁻. Sulfur and oxygen are both nonmetals, thus covalently combining. The ionic bond forms between the  Na⁺ and SO₄²⁻. Sodium (Na) is a metal which wishes to give up electrons to have a complete octet. SO₄²⁻ serves as the anion which it bonds with.

CH₃COOH contains hydrogen, carbon, and oxygen. All of these are nonmetals, thus the only bonds formed are covalent.

NaCl contains sodium, a metal, and chlorine, a nonmetal. Therefore, this compound is held together by an ionic bond.

The value of the boiling point elevation constant (Kb) depends on the identity of the solute and solvent. Thus option E is correct.

The major difference is that the melting point is the temperature at which solid and liquid phases are at equilibrium state, whereas the boiling point is the temperature at which the vapor pressure of a liquid is equal to the external pressure.

Melting point in which the solid will start melting to become a liquid at a given temperature, the molecules gain enough amount of kinetic energy to overcome the intermolecular forces to convert into another form.

Another term called the freezing point is the temperature at which conversion of a liquid into solid occur.

Boiling point at which , the  liquid substance enters into the gaseous phase, when the external pressure is high then a higher temperature for the vapor pressure is needed to become equal to the external pressure.

Answer: There are a total of two bonded atoms in carbon monoxide: one carbon atom and one oxygen atom. There are no lone pairs in carbon monoxide.

Explanation:  Carbon monoxide, or CO, is a chemical compound made up of one carbon atom bonded to one oxygen atom. The molecule has a linear shape, with the carbon atom at one end and the oxygen atom at the other end. There are a total of two bonded atoms in carbon monoxide: one carbon atom and one oxygen atom.

In terms of lone pairs, or non-bonding electrons, carbon monoxide has none. Lone pairs are pairs of electrons that are not involved in bonding, and they are typically found in the outermost electron shell of an atom. In carbon monoxide, all of the electrons are either bonded to the other atom in the molecule or are involved in bonding to that atom. Therefore, there are no lone pairs in carbon monoxide.

Option B is the correct effect of the size of a sample on the melting point measurement. A larger sample size can indeed produce a higher and broader melting point (mp) range.

This is because the temperature at which a solid melts can be affected by impurities or irregularities in the sample, and a larger sample size can increase the chances of such variations occurring. As a result, the melting point range can be less precise and may cover a wider range of temperatures, leading to a less accurate measurement. Therefore, it is important to use an appropriate sample size that is not too large, but also not too small, to obtain the most accurate and precise melting point measurement.
