Answer:

The partial pressure of carbon dioxide is 22.8 mmHg

Explanation:

Dalton's Law is a gas law that relates the partial pressures of the gases in a mixture. This law says that the pressure of a gas mixture is equal to the sum of the partial pressures of all the gases present.

In this case:

Ptotal=Pnitrogen + Poxygen + Pcarbondioxide

You know that:

Replacing:

0.998 atm=0.770 atm + 0.198 atm + Pcarbondioxide

Solving:

Pcarbondioxide= 0.998 atm - 0.770 atm - 0.198 atm

Pcarbondioxide= 0.03 atm

Now you apply the following rule of three: if 1 atm equals 760 mmHg, 0.03 atm how many mmHg equals?

\(Pcarbondioxide=\frac{0.03 atm*760 mmHg}{1 atm}\)

Pcarbondioxide= 22.8 mmHg

The partial pressure of carbon dioxide is 22.8 mmHg

The normalized energy eigenstates for the 3D spherical infinite square well with zero angular momentum (s-states) are R(r) = A * j0(kr), where k is determined by the zeros of the zeroth-order spherical Bessel function j0(ka) = 0, and E = (ħ^2k^2)/(2m).

The potential energy within this box is defined as follows:

V(r) =

- infinity if r < 0 or r > 2a

0 if 0 ≤ r ≤ 2a

We are asked to assume that the angular momentum (L) is zero, which corresponds to s-states. This allows us to focus on the radial component of the wave function and largely ignore the spherical harmonics (Y(θ, φ)).

To solve for the normalized energy eigenstates and eigenvalues, we need to solve the radial Schrödinger equation:

(-ħ^2/2m) * (d^2/dr^2) * R(r) + V(r) * R(r) = E * R(r)

Where:

ħ is the reduced Planck's constant

m is the mass of the particle

d^2/dr^2 represents the second derivative with respect to r

R(r) is the radial wave function

E is the energy eigenvalue

Given that the angular momentum is zero, the potential energy term becomes zero within the spherical box, simplifying the equation to:

(-ħ^2/2m) * (d^2/dr^2) * R(r) = E * R(r)

We can rewrite this equation as:

(d^2/dr^2) * R(r) = -((2mE)/ħ^2) * R(r)

The solution to this differential equation is in terms of Bessel functions, and the eigenvalues are quantized. The normalized energy eigenstates can be expressed as:

R(r) = A * j0(kr)

Where:

A is the normalization constant

j0 is the zeroth-order spherical Bessel function

k = √((2mE)/ħ^2)

The eigenvalues E can be determined by imposing the boundary condition that the wave function vanishes at r = a, which means that j0(ka) = 0. This condition gives us the quantized values for k and subsequently for E.

The zeros of the zeroth-order spherical Bessel function, denoted as j0(ka) = 0, provide the values of ka that satisfy the boundary condition. These zeros are typically tabulated or numerically determined. By solving j0(ka) = 0, we can find the values of k that correspond to the eigenvalues E.

To summarize, the normalized energy eigenstates for the 3D spherical infinite square well with zero angular momentum (s-states) are given by R(r) = A * j0(kr), where k is determined by the zeros of the zeroth-order spherical Bessel function j0(ka) = 0, and E = (ħ^2k^2)/(2m).

Given mass of water (m1) = 51.203g

Temperature of water (T1) = 55.2c

mass of water (m2) = 49.783g

Temperature of water (T2) = 37.6c

the final temperature reached is = 37.6c

So Qwater = 51.203 x 4.184 x (23.5 - 55.2) = 6791.9J

Qcalo = 49.783 x Cp x (23.5 - 37.6) = 701.9 x Cp

The partial pressure of \($Cl_2$\) in the mixture is 3.25 atm. The partial pressure of a gas in a mixture is the pressure that gas would exert if it alone occupied the volume of the mixture at the same temperature.

To calculate the partial pressure of \($Cl_2$\) in the given mixture, we need to use the ideal gas law, which relates the pressure, volume, temperature, and number of moles of a gas:

PV = nRT

where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature.

We can rearrange this equation to solve for the number of moles of a gas:

n = PV/RT

Now, we can use the given asses of \($Cl_2$\) and N2 to calculate the number of moles of each gas:

\($n(Cl_2)=\frac{m(Cl_2)}{M(Cl_2)}$\)

= 35.45 g / 70.91 g/mol

= 0.499 mol

\($n(N_2)=\frac{m(N_2)}{M(N_2)}$\)

= 28.02 g / 28.01 g/mol

= 0.999 mol

The total number of moles of gas in the mixture is the sum of the moles of \($Cl_2$\) and N2:

n(total) = n(\($Cl_2$\)) + n(\($N_2$\)) = 1.498 mol

Now, we can use the total pressure of the mixture to calculate the partial pressure of \($Cl_2$\):

\($P(Cl_2)=\frac{n(Cl_2)RT}{V}$\)

= \($(0.499\text{ mol})\left(\frac{0.08206\text{ L}\cdot\text{atm}}{\text{mol}\cdot\text{K}}\right)(298\text{ K})/V$\)

Similarly, we can calculate the partial pressure of N2:

\($P(N_2)=\frac{n(N_2)RT}{V}$\)

= \($(0.999\text{ mol})\left(\frac{0.08206\text{ L}\cdot\text{atm}}{\text{mol}\cdot\text{K}}\right)(298\text{ K})/V$\)

The sum of the partial pressures must equal the total pressure:

\($P(Cl_2)+P(N_2)$\) = 6.0 atm

Substituting the expressions for P(\($Cl_2$\)) and P(\($N_2$\)) and simplifying, we get:

\($(0.499\text{ mol})\left(\frac{0.08206\text{ L}\cdot\text{atm}}{\text{mol}\cdot\text{K}}\right)(298\text{ K})/V + (0.999\text{ mol})\left(\frac{0.08206\text{ L}\cdot\text{atm}}{\text{mol}\cdot\text{K}}\right)(298\text{ K})/V$\)

= 6.0 atm

Solving for V, we get:

V = 2.28 L

Now, we can substitute the value of V into the expression for P(\($Cl_2$\)) and simplify to get:

\($P(Cl_2)=\frac{(0.499\text{ mol})\left(\frac{0.08206\text{ L}\cdot\text{atm}}{\text{mol}\cdot\text{K}}\right)(298\text{ K})}{2.28\text{ L}}$\)

Sublimation is the phase transition in which a solid instantly transforms into a gas. When a substance's temperature and pressure are such that the solid phase can transition directly to the gas phase without first going through the liquid phase, this is known as sublimation. In contrast to deposition, which skips the liquid phase and converts a gas directly into a solid, this process does the opposite.

In nature, sublimation occurs often and may be seen in a number of settings. For instance, under ambient temperature and pressure, dry ice (solid carbon dioxide) sublimes to create a gas that is frequently employed in special effects and for food preservation. Similar to this, under some circumstances, snow and ice may sublimate and release water vapor.
