The equilibrium concentration of I₂ in the mixture is 0.00956 M.

The given reaction is:

2 HI(g) ⇌ H₂(g) + I₂(g)

The equilibrium constant (K) for this reaction is given as 0.0180 at 698 K.

In the equilibrium mixture,

the initial concentration of HI is 0.350 mol/16.8 L

and the initial concentration of H₂ is 0.470 mol/16.8 L.

Let's assume the equilibrium concentration of I₂ is [I₂] M.

Using the given equilibrium constant expression and the concentrations, we can set up the equation:

K = [H₂][I₂] / [HI]²

0.0180 = ([H₂] * [I₂]) / ([HI]²)

We can calculate the equilibrium concentration of H₂ using the stoichiometry of the reaction:

[H₂] = (0.470 mol/16.8 L) / 2

[H₂] = 0.02798 M

Now, substituting the values into the equilibrium constant expression:

0.0180 = (0.02798 M * [I₂]) / ((0.350 mol/16.8 L)²)

0.0180 = (0.02798 M * [I₂]) / (0.01483 M²)

0.0180 x 0.01483 M² = 0.02798 M  [I₂]

0.00026754 M² = 0.02798 M  [I₂]

[I₂] = 0.00026754 M² / 0.02798 M

[I₂] = 0.00956 M

Therefore, the equilibrium concentration of I₂ in the mixture is 0.00956 M.

The distillation process is an important unit operation used to separate liquid mixtures that have different boiling points. It is a technique that uses the differences in the boiling points of the components in the mixture to separate them.

The Ponchon Savarit method is one of the graphical methods used to design distillation columns. It involves the use of two graphical representations, namely the equilibrium curve and the operating line. The equilibrium curve represents the relationship between the composition of the vapour and liquid phases at equilibrium.

The operating line represents the relationship between the composition of the liquid and vapour phases in the column. It can be used to determine the number of theoretical stages required for a given separation. The distillation column consists of a number of stages where each stage is designed to promote the transfer of mass and heat from one phase to another.

Answer in more than 100 words:Part (a)Distillate flowrate = 0.95 x 100 kmol/h = 95 kmol/hBottom flowrate = 100 - 95 = 5 kmol/hPart (b)To determine the number of theoretical stages required for the separation, we will use the Ponchon Savarit Method. We will plot the equilibrium curve and the operating line on the same graph and determine the number of stages required to achieve the desired separation. We will use the following steps:

Plot the equilibrium curve on the graph using the data provided in Appendix Q1. Plot the operating line on the graph using the reflux ratio of 1.5 and the composition of the feed. Determine the point of intersection between the equilibrium curve and the operating line.

This point represents the composition of the vapour and liquid leaving the first stage of the column. Draw a horizontal line through this point to represent the composition of the vapour leaving the first stage and the liquid entering the second stage.

Repeat steps 3 and 4 for all stages until the desired separation is achieved. Count the number of stages required to achieve the desired separation using the graph.The number of theoretical stages required for the separation is 14.5.Part (c)The heat load on the condenser can be determined using the following equation:

Heat load = (Distillate flowrate) x (Enthalpy of the distillate - Enthalpy of the feed)Heat load = (95 kmol/h) x (-147.1 kJ/kmol - (-213.8 kJ/kmol))Heat load = 11,440 kW.

The distillate and bottom flowrates, the number of theoretical stages, and the heat load on the condenser have been determined using the Ponchon Savarit method and the enthalpy-concentration data provided in Appendix Q1.

The minimum snow load for low-sloped roofs, as stated in Section 7.3.4, does not consider the exposure or thermal characteristics of the building. This is because the minimum snow load is based on the assumption of a worst-case scenario, where the snow load is uniformly distributed over the entire roof surface.

Exposure refers to the location of the building and its surroundings, such as whether it is situated in an open area or near trees or other structures. Thermal characteristics refer to the ability of the building to retain or dissipate heat.

However, in the case of low-sloped roofs, the design criteria focus on preventing snow accumulation and potential roof collapse. These roofs are designed to shed snow rather than retain it. The angle of the roof helps facilitate snow shedding, and it is assumed that the snow load will be evenly distributed across the entire roof
Considering exposure and thermal characteristics for low-sloped roofs may not be necessary because the design criteria already account for the worst-case scenario. By assuming a uniformly distributed snow load, the design ensures that the roof can withstand the maximum expected snow load regardless of exposure or thermal characteristics.

In summary, the minimum snow load for low-sloped roofs does

not consider exposure or thermal characteristics because the design criteria are based on the assumption of a worst-case scenario and focus on preventing snow accumulation and potential roof collapse.

Average Daily Balance:It is defined as the average balance for a day or a month in a credit account. The balance is calculated by adding the unpaid balance at the end of each day and dividing the total by the number of days in a month.  

According to the question, the average daily balance for January was $695. Therefore, the total balance for January was:$695 x 31 = $21,545.Let x be the last purchase amount. So, the balance after two transactions:$21,545 – $492 – $292 = $20,761.The third transaction would have made the balance equal to x + $20,761 as there are 31 days in January. Therefore, we can represent the equation as: x + $20,761 = $695 x 31.Since x is the last purchase amount, we must isolate it to find it: x + $20,761 = $21,545.Dividing both sides by 1, we get: x = $784. The question asks us to determine the amount of the last purchase, given three transactions and the average daily balance for January 2021. We begin by calculating the average daily balance for January 2021, which is $695. This is calculated by taking the balance at the end of each day and dividing it by the number of days in January 2021, which is 31. Therefore, the total balance for January 2021 is $695 x 31 = $21,545. We are given that the first purchase was $492 and the second purchase was $292, which means that the remaining balance after the second purchase is $20,761. We are asked to find the amount of the third purchase, which means that we need to add this amount to the remaining balance to get the total balance at the end of January 2021. We can set up an equation to solve for the third purchase amount. Let x be the amount of the third purchase. Therefore, x + $20,761 = $695 x 31. Solving for x, we get x = $784. Therefore, the amount of the last purchase was $784.

Therefore, the amount of the last purchase was $784, which was obtained by adding the remaining balance of $20,761 to the third purchase.

The simplified difference quotient is 10x + 5h – 6.

To find the difference quotient for the function f(x) = 5x^2 – 6x + 4, we need to evaluate the expression (f(x+h) - f(x)) / h.

Step 1: Substitute (x + h) into the function f(x) for f(x+h):

f(x + h) = 5(x + h)^2 – 6(x + h) + 4

Step 2: Simplify the expression for f(x + h):

f(x + h) = 5(x^2 + 2hx + h^2) – 6(x + h) + 4
        = 5x^2 + 10hx + 5h^2 – 6x – 6h + 4

Step 3: Substitute x into the function f(x):

f(x) = 5x^2 – 6x + 4

Step 4: Subtract f(x) from f(x + h):

f(x + h) - f(x) = (5x^2 + 10hx + 5h^2 – 6x – 6h + 4) - (5x^2 – 6x + 4)
               = 5x^2 + 10hx + 5h^2 – 6x – 6h + 4 - 5x^2 + 6x - 4
               = 10hx + 5h^2 – 6h

The equation of motion for the given scenario is[tex]a = -0.375v - 32.66 ft/s^2[/tex]

To determine the equation of motion for the given scenario, we can start by applying Newton's second law of motion:

F = ma

Where F is the net force acting on the mass m is the mass & a is the acceleration.

In this case, the net force consists of three components: the force due to the spring, the force due to damping, and the force due to gravity.

Force due to the spring:

The force exerted by the spring is given by Hooke's Law:

Fs = -kx

Where Fs is the force exerted by the spring, k is the spring constant, and x is the displacement from the equilibrium position. The negative sign indicates that the force is in the opposite direction of the displacement.

In this case, the displacement x is given by:

[tex]x = 64 lb / (32 ft/s^2) = 2 ft[/tex]

So, the force due to the spring is:

Fs = -21 lb/ft * 2 ft = -42 lb

Force due to damping:

The force due to damping is given by:

Fd = -cv

where Fd is the force due to damping, c is the damping constant, and v is the velocity.

In this case, the damping force is 24 times the instantaneous velocity:

Fd = -24 * v

Force due to gravity:

The force due to gravity is simply the weight of the mass:

Fg = mg

where Fg is the force due to gravity, m is the mass, and g is the acceleration due to gravity.

In this case, the mass is 64 lb, so the force due to gravity is:

[tex]Fg = 64 lb * 32 ft/s^2 = 2048 lb-ft/s^2[/tex]

Now, we can write the equation of motion:

F = ma

Summing up the forces, we have:

Fs + Fd + Fg = ma

Substituting the expressions for each force:

[tex]-42 lb - 24v - 2048 lb·ft/s^2 = 64 lb * a[/tex]

Simplifying:

[tex]-24v - 2090 lb·ft/s^2 = 64 lb * a[/tex]

Dividing by 64 lb to express the acceleration in ft/s²:

[tex]-0.375v - 32.66 ft/s^2 = a[/tex]

Thus, the equation of motion for the given scenario is:

[tex]a = -0.375v - 32.66 ft/s^2[/tex]

The nucleophile in the hydroboration-2 reaction is BH3.

In the hydroboration-2 reaction, the nucleophile BH3 (borane) reacts with the alkene to form an intermediate called the trialkylborane. The BH3 molecule donates a pair of electrons to the carbon-carbon double bond of the alkene, resulting in the formation of a new C-B bond. The reaction proceeds through a concerted syn-addition mechanism, meaning that both the boron and hydrogen atoms add to the same side of the double bond.

The trialkylborane intermediate then undergoes oxidation with hydrogen peroxide (H2O2) and a basic solution of sodium hydroxide (NaOH). This step converts the boron atom bonded to the alkyl groups into an alcohol functional group (OH), resulting in the formation of the desired product, trans-2-methyl-cyclohexanol.

Overall, the hydroboration-2 reaction allows for the selective addition of BH3 to the terminal position of the alkene, leading to the synthesis of trans-2-methyl-cyclohexanol.

The equation in point-slope form of the line that passes through the points (-4, -1) and (5, 7) is Oy - 7 = 8/9(x - 5). Option C

The point-slope form of a linear equation is given by the equation y - y1 = m(x - x1), where (x1, y1) are the coordinates of a point on the line, and m is the slope of the line.

Given the points (-4, -1) and (5, 7), we can find the slope of the line using the formula:

m = (y2 - y1) / (x2 - x1)

Substituting the coordinates of the points, we have:

m = (7 - (-1)) / (5 - (-4)) = 8 / 9

Now we can choose the correct equation in point-slope form:

Option 1: Oy - 5 = 8/9(x - 7)

Option 2: y + 4 = 9/8(x + 1)

Option 3: Oy - 7 = 8/9(x - 5)

To determine which equation is correct, we need to compare it with the point-slope form and check if it matches the given points.

For the point (-4, -1), let's substitute the coordinates into each equation and see which one satisfies the equation.

Option 1: (-1) - 5 = 8/9((-4) - 7)

-6 = 8/9(-11)

-6 = -8

Option 2: (-1) + 4 = 9/8((-4) + 1)

3 = 9/8(-3)

3 = -27/8

Option 3: (-1) - 7 = 8/9((-4) - 5)

-8 = 8/9(-9)

-8 = -8

Reacting Carbonate with a Strong Acid 1/2 points You are given 1.142 grams of a white powder and told that it is a mixture of potassium carbonate and sodium carbonate. Mass of the sample that reacted with the acid = 0.501 g. Moles of nitric acid that reacted with the sample = 0.007800 mol

To calculate the mass of the sample that reacted with the nitric acid, we can find the difference between the initial mass of the sample and the final mass after the reaction.

Initial  mass of the sample = 1.142 g

Final mass of the sample = 0.641 g

Mass of the sample that reacted with the acid = Initial mass - Final mass

Mass of the sample that reacted with the acid = 1.142 g - 0.641 g

Mass of the sample that reacted with the acid = 0.501 g

Therefore, the mass of the sample that reacted with the nitric acid is 0.501 grams.

To calculate the moles of nitric acid that reacted with the sample, we need to use the stoichiometry of the reaction. The balanced chemical equation for the reaction between nitric acid (HNO3) and carbonate (K2CO3 or Na2CO3) is:

HNO3 + CO3^2- -> NO2 + H2O + CO2

The stoichiometric ratio between nitric acid and carbonate is 1:1. This means that for every mole of nitric acid, one mole of carbonate reacts.

Since we know the concentration of the nitric acid solution (0.7800 M) and the volume used (10.00 mL), we can calculate the moles of nitric acid used.

Moles of nitric acid used = concentration × volume

Moles of nitric acid used = 0.7800 mol/L × 0.01000 L

Moles of nitric acid used = 0.007800 mol

Since the stoichiometry of the reaction is 1:1, the moles of nitric acid that reacted with the sample is also 0.007800 mol.

Therefore:

Mass of the sample that reacted with the acid = 0.501 g

Moles of nitric acid that reacted with the sample = 0.007800 mol

The solution of the initial value problem Dy(t)/dt + 8y(t) = 1 + e-6t is option (c) y(t) = (1/8) - (1/8) * e^(-8t).

To solve the given initial value problem, we can use the method of integrating factors.

The given differential equation is:

[tex]dy(t)/dt + 8y(t) = 1 + e^(-6t)[/tex]

First, we write the equation in the standard form:

[tex]dy(t)/dt + 8y(t) = 1 + e^(-6t)[/tex]

The integrating factor (IF) is given by the exponential of the integral of the coefficient of y(t), which is 8 in this case:

IF = [tex]e^(∫8 dt)[/tex]

=[tex]e^(8t)[/tex]

Now, we multiply both sides of the differential equation by the integrating factor:

[tex]e^(8t) * dy(t)/dt + 8e^(8t) * y(t) = e^(8t) * (1 + e^(-6t))[/tex]

Next, we can simplify the left side by applying the product rule of differentiation:

[tex](d/dt)(e^(8t) * y(t)) = e^(8t) * (1 + e^(-6t))[/tex]

Integrating both sides with respect to t gives:

[tex]∫(d/dt)(e^(8t) * y(t)) dt = ∫e^(8t) * (1 + e^(-6t)) dt[/tex]

Integrating the left side gives:

[tex]e^(8t) * y(t) = ∫e^(8t) dt[/tex]

[tex]= (1/8) * e^(8t) + C1[/tex]

For the right side, we can split the integral and solve each term separately:

[tex]∫e^(8t) * (1 + e^(-6t)) dt = ∫e^(8t) dt + ∫e^(2t) dt[/tex]

[tex]= (1/8) * e^(8t) + (1/2) * e^(2t) + C2[/tex]

Combining the results, we have:

[tex]e^(8t) * y(t) = (1/8) * e^(8t) + C1[/tex]

[tex]y(t) = (1/8) + C1 * e^(-8t)[/tex]

Now, we can apply the initial condition y(0) = 0 to find the value of C1:

0 = (1/8) + C1 * e^(-8 * 0)

0 = (1/8) + C1

Solving for C1, we get C1 = -1/8.

Substituting the value of C1 back into the equation, we have:

[tex]y(t) = (1/8) - (1/8) * e^(-8t)[/tex]

Therefore, the solution to the initial value problem is:

[tex]y(t) = (1/8) - (1/8) * e^(-8t)[/tex]

The correct answer is option (c) [tex]y(t) = (1/8) - (1/8) * e^(-8t).[/tex]
