The concentration of A in the effluent at steady-state is 5 mole/m³. The yield of B in the effluent at steady-state is 2. The concentration of A in the effluent reach 75% of its steady-state value will be 57.62 minutes.

i. Since there is no cellobiose accumulation in the reactor, the rate of cellobiose consumption (RA) ought to be equal to the rate of cellobiose input (Q × CA₀) at steady-state.

RA = Q × CA₀

The formula RA = -4CA, where k = 0.012/min, yields the rate of cellobiose consumption. Therefore,

-4CA = Q × CA₀

Solving for CA, we get:

CA = -(Q × CA₀)/4

With the values Q = 2 m³/min and CA0 = 10 mole/m³ substituted, the following is obtained:

CA = -(2 × 10)/4

CA = -5 mole/m³

Since the concentration cannot be negative, we take the absolute value:

CA = 5 mole/m³

Therefore, the concentration of A in the effluent at steady-state is 5 mole/m³.

ii. The ratio of the moles of B produced to the moles of A consumed is known as the yield of B. Since A is changed into 2B in this instance, the yield of B is 2.

iii. The first-order reaction kinetics equation can be used to calculate how long it will take for the concentration of A in the effluent to get to 75% of its steady-state value:

CA(t) = CA₀ × [tex]e^{-kt}[/tex]

Where:

CA(t) = concentration of A at time t

CA₀ = initial concentration of A

k = rate constant

t = time

We set up the following equation to determine the time at which CA(t) reaches 75% of CA (steady-state):

0.75 × CA = CA₀ × [tex]e^{-kt}[/tex]

Substituting the given values, CA = 5 mole/m³, CA₀ = 10 mole/m³, and k = 0.012/min:

0.75 × 5 = 10 × [tex]e^{-0.012t}[/tex]

0.75 = [tex]e^{-0.012t}[/tex]

Taking the natural logarithm of both sides:

ln(0.75) = -0.012t

Solving for t:

t = ln(0.75)/(-0.012)

Using a calculator, we find:

t ≈ 57.62 minutes

The concentration of A in the wastewater will therefore take around 57.62 minutes to reach 75% of its steady-state value.

iv. Since A is changed into 2B, B's concentration will be double that of A.

CB = 2 × CA

Substituting the steady-state concentration of A (CA = 5 mole/m³), we get:

CB = 2 × 5 = 10 mole/m³

Therefore, at the time found in part iii, the concentration of B in the effluent will be 10 mole/m³.

Agenda setting theory refers to the idea that media has the power to choose what issues and topics are important for public discussion. In other words, the media's coverage and focus can determine what people think and talk about.

This theory argues that the media doesn't tell people what to think, but it does tell people what to think about.Initial research to show agenda setting in the media was conducted by McCombs and Shaw in 1972. They conducted a study during the 1968 presidential election campaign, in which they surveyed 100 residents of Chapel Hill, North Carolina.

They asked them what issues they thought were important in the election campaign. They also analyzed the content of the news coverage of the campaign in two local newspapers in the area. They found that the issues that the residents thought were important corresponded with the issues that were heavily covered in the news. They concluded that the media's coverage of an issue can strongly influence what people consider important and relevant.\

The entry to record when already written-off bad debt is collected in cash should be "Debit: Cash and Credit: Accounts Receivable". Option A is the correct answer.

When a previously written-off bad debt is collected in cash, it is a recovery of an amount that was previously deemed uncollectible. The entry to record this transaction involves debiting the Cash account to reflect the increase in cash received and crediting the Accounts Receivable account to reduce the outstanding accounts receivable balance. This entry reverses the initial write-off entry and reflects the collection of the previously written-off amount. The Allowance for Bad Debts account is not involved in this entry because it represents an estimate of potential bad debts and is not affected by the collection of a specific written-off debt.

Option A is the correct answer.

Explanation:

Homophones are words that have the same sounds but differ in their meaning and spelling. This means that some words are the same in the way they are pronounced but their similarity ends there and they are totally different in their spelling and meaning.

In the given sentence, that particular word is "its/it's". Here, the difference lies in the use of the inverted comma, which totally changed everything. "Its" refer to the possessive nature of the noun or pronoun whereas "it's" is the contracted form of 'it is'.

Now, the sentence that uses the correct version of the homophone 'its' is the second sentence.

Here, the 'its' is used to refer to the strap of the purse, which is correct. The 'its' in the other sentences are supposed to be 'it's'.

Thus, the correct answer is "She carried the purse by its strap."

Explanation: in passage 2 you should see the answer

If I could be anything I wanted to be, I would be a bird soaring high above the clouds. I would spread my wings and feel the rush of wind beneath me. The freedom and joy that comes with flying is unmatched by anything else. I would be able to explore the world from a completely different perspective, seeing things that I could only imagine from the ground.

As a bird, I could fly to different places, experience different cultures and marvel at the beauty of the world.

This poem is an example of using a metaphor to describe what I would want to be if I could be anything. I am comparing myself to a bird and using its characteristics to describe the experience that I crave. The use of sensory language, such as the rush of wind, helps to create a vivid image in the reader's mind.

Another example of literary devices used in the poem is personification. I say that I would be able to explore the world and marvel at its beauty. The world is not capable of being marveled at, but by using personification, I am giving the world human-like qualities.

Lastly, imagery is another literary device that is used throughout the poem. I paint a picture in the reader's mind of what it would feel like to fly, what I would see, and what I would experience. Through the use of vivid descriptions and sensory language, I help the reader to feel as if they are experiencing the joy and freedom of flying alongside me.
