1) She would find  "ballistic markings" or "striations."

2) She would find the whorl pattern of finger prints

As a crime scene investigator, Jessa will search for distinctive signs on the bullet that could identify it as coming from a particular firearm. Common names for these stains include "ballistic markings" and "striations." When a bullet travels through a gun's barrel, it may leave behind distinctive traces due to flaws in or wear on the rifling, spiral grooves carved into the barrel to stabilize the projectile. These traces are imprinted on the bullet's surface and can be examined to identify the weapon type.

Jessa will likely use a comparison microscope to inspect the bullet and compare the ballistic marks to test-fired bullets from potential guns.

Explanation:

In the J = 0 state, the BrF molecule does not undergo any revolutions per second. In the J = 1 state, it undergoes approximately 0.498 revolutions per second, and in the J = 10 state, it undergoes approximately 15.71 revolutions per second.

To calculate the rotational constant B, we can use the formula:

B = 1 / (2 * π * Δν)

Where:

B = rotational constant

Δν = spacing between consecutive lines in the rotational spectrum

Given that the spacing between consecutive lines is 0.71433 cm^(-1), we can substitute this value into the formula:

B = 1 / (2 * π * 0.71433 cm^(-1))

B ≈ 0.079 cm^(-1)

The moment of inertia (I) of the molecule can be calculated using the formula:

I = h / (8 * π^2 * B)

Where:

h = Planck's constant

Given that the value of Planck's constant (h) is approximately 6.626 x 10^(-34) J·s, we can substitute the values into the formula:

I = (6.626 x 10^(-34) J·s) / (8 * π^2 * 0.079 cm^(-1))

I ≈ 2.11 x 10^(-46) kg·m^2

The bond length (r) of the molecule can be determined using the formula:

r = sqrt((h / (4 * π^2 * μ * B)) - r_e^2)

Where:

μ = reduced mass of the molecule

r_e = equilibrium bond length

To calculate the wavenumber (ν) of the J = 9+ to J = 10 transition, we can use the formula:

ν = 2 * B * (J + 1)

Substituting J = 9 into the formula, we get:

ν = 2 * 0.079 cm^(-1) * (9 + 1)

ν ≈ 1.58 cm^(-1)

To determine the most intense spectral line at room temperature (300 K), we can use the Boltzmann distribution law. The intensity (I) of a spectral line is proportional to the population of the corresponding rotational level:

I ∝ exp(-E / (k * T))

Where:

E = energy difference between the levels

k = Boltzmann constant

T = temperature in Kelvin

At room temperature (300 K), the population distribution decreases rapidly with increasing energy difference. Therefore, the transition with the lowest energy difference will have the most intense spectral line. In this case, the transition from J = 0 to J = 1 will have the most intense spectral line.

To calculate the number of revolutions per second, we can use the formula:

ω = 2 * π * B * J

Where:

ω = angular frequency (in radians per second)

J = rotational quantum number

For J = 0:

ω = 2 * π * 0.079 cm^(-1) * 0 = 0 rad/s

For J = 1:

ω = 2 * π * 0.079 cm^(-1) * 1 ≈ 0.498 rad/s

For J = 10:

ω = 2 * π * 0.079 cm^(-1) * 10 ≈ 15.71 rad/s

The value of S2 is S₂ = 2.1 g/L.Approximately 2.1 g of the gas will dissolve in 2 L of water at 0.6 ATM, assuming the temperature remains constant.

To determine the amount of gas that will dissolve in 2 L of water at 0.6 ATM, we can use Henry's law, which states that the solubility of a gas is directly proportional to the partial pressure of the gas above the liquid.

According to Henry's law, the solubility of a gas can be represented as:S₁/P₁ = S₂/P₂,,where S₁ and S₂ are the solubilities of the gas at the respective pressures P₁ and P₂.Given that 7 g of the gas dissolves in 1 L of water at 2.0 ATM, we can consider this as our initial condition, denoted by S₁/P₁.

Now, we need to find the solubility at 0.6 ATM in 2 L of water, denoted by S₂/P₂.Since the temperature remains constant, we can assume that the solubility of the gas does not change. Therefore, we can rewrite the equation as:

S₁/P₁ = S₂/P₂,

Substituting the known values, we have:

(7 g/1 L)/(2.0 ATM) = S₂/(0.6 ATM),

Solving for S₂, we get:

S₂ = (7 g/1 L) * (0.6 ATM)/(2.0 ATM),

S₂ = 2.1 g/L.

KH2PO4 is a more suitable choice as a buffer because it has a greater buffering capacity due to the presence of the weak acid and its conjugate base.

KHPo4 is not considered an effective buffer compared to KH2PO4 due to its limited buffering capacity. The effectiveness of a buffer is determined by the concentration and dissociation properties of its conjugate acid-base pair.

KH2PO4 is a salt composed of the weak acid H2PO4- and its conjugate base HPO4^2-. In an aqueous solution, KH2PO4 can dissociate to release H+ ions from the H2PO4- component, which acts as a weak acid, and the HPO4^2- component can accept H+ ions, acting as a weak base. This allows KH2PO4 to effectively resist changes in pH when small amounts of acid or base are added to the solution.

On the other hand, KHPo4 consists of the strong acid H3PO4 and the weak base HPO4^2-. H3PO4 fully dissociates in water, providing a large concentration of H+ ions, making it difficult for the HPO4^2- to effectively act as a base and maintain pH stability.

Therefore, KH2PO4 is a more suitable choice as a buffer because it has a greater buffering capacity due to the presence of the weak acid and its conjugate base.

An acetate buffer would be most effective in maintaining pH within a range of approximately 3.76 to 5.76.

The pH range over which an acetate buffer can effectively maintain pH depends on the pKa of the acid used and the concentration ratio of the acid to its conjugate base (acetate ion). Acetate buffer solutions are commonly prepared using acetic acid (CH3COOH) and sodium acetate (CH3COONa).

The pKa of acetic acid is approximately 4.76. In general, a buffer is most effective when the pH is within one unit of its pKa. Therefore, an acetate buffer would be most effective in maintaining pH within a range of approximately 3.76 to 5.76

Outside this pH range, the buffer may not effectively resist changes in pH, as the concentration of the acid and its conjugate base will be significantly imbalanced. At lower pH values, the acid concentration will dominate, while at higher pH values, the concentration of the acetate ion will dominate, leading to a diminished buffering capacity.

However, it's important to note that the exact pH range over which an acetate buffer can maintain pH effectively may vary depending on the specific concentration and preparation of the buffer solution.
