The vapour pressure of pure benzene at a certain temperature is 0.850 bar. A non volatile, non electrolyte solid weighing 0.5 g is added to 39.0g of benzene. The vapour pressure of the solution then is 0.845 bar. What is the molecular mass of the solid substance​

Answers

Answer 1

Answer:

The molar mass is 169g / mol.

Explanation:

To achieve this result you must consider the formula:

[(pº-p) / pº] = [na / (na + nb)]

This formula should be replaced by the values shown in the question as follows:

pº = 0.850 bar

p = 0.845 bar

To find the values of "na" and "nb", we will consider that the letter "m" represents the molecular mass of benzene that is equal to 78, so we have:

na = 0.5 / m; nb = 39/78 = 0.5

Now we can replace all values in the formula:

0.850-0.845 / 0.850 = (0.5 / m) / (0.5 / m) +0.5 =

0.5 / (0.5 = 0.5m) =

1/1 + m =

m = 0.850 / 0.005 - 1 = 169g / mol

1. Read the short personal essay by George Orwell.2. Answer the following questions. _How are the Europeans presented in this story? What are they like?_How are the Burmese presented? what are they like? _who do you empathize the most with? _ Describe the presence of prejudice and racism in the story events as well as Orwell's narration(wording choice).

Answers

Answer:

"Shooting an Elephant"

The Europeans are presented as imperialists who think that they are in control not knowing that they have lost their will power to the natives, whom they think they dominate. The Europeans are described like masked people who have grown to resemble the masks they wear with ingrained habits and prejudices.

The Burmese are presented as idle, idiotic, and lacking the coercive power necessary to be in obvious control of their lives, especially since they have no physical weapons.  However, what they lack in physical weapons, they possess in abundance with the power of the will.  This implies that their lack of physical weapons does not make them powerless in the real sense.  They have will.  With it, they control the Europeans who weld physical power.  

I empathize mostly with the Europeans.  Their portrayal by George Orwell is very sympathetic.  By trying to impose their authority on others, they limit their ability to even control their own lives.  They must dance to the music of the crowd because of the expectations placed on them by the natives.  The same is true of all rulers who have refused to embrace leadership principles, thinking that they are in charge of the people, not realizing that it is the people that control them with their crowd expectations.

Europeans are not accepted by others.  Europeans do not accept others.  Each tribe thinks highly of themselves and belittles the others.  But, we are all human beings, created in God’s image and likeness.  The moment we overcome our prejudices, it is the same moment that we are liberated to fulfil God’s mandate, “to exercise dominion over the earth.”  This dominion is not the domination of other people, but the dominion of the elements that make up the earth, the forces, and the evils that attempt to take over the earth that God has created for the welfare of human beings.  We must collaborate, cherish each other, and find joy in our diversity as humans.  We must act together in love.  Conclusively, George Orwell’s observation is true of all human beings, “when the white man (read, “any class of humanity”) turns tyrant, it is his own freedom that he destroys.”

Explanation:

George Orwell's 1936 short story titled: "Shooting an Elephant" describes his experiences as a police officer in Burma.  In it, he denounces British imperialism as lacking common sense.  Europeans are made a laughing stock of by the natives they try to rule.  According to George Orwell, Imperialism and colonialism are evil as no good has come from the imposition of another's will on others.

The writer wants to introduce the topic of electronegativity with a concrete, casually observable example from the natural world. Which choice best accomplishes this goal

Answers

Answer:

B. How do water striders skim across the surfaces of ponds and lakes? Their hydrophobic legs are uniquely suited to this process, but the insects

Explanation:

Below are the options given:

A. NO CHANGE

B. How do water striders skim across the surfaces of ponds and lakes? Their hydrophobic legs are uniquely suited to this process, but the insects

C. How do our bodies break down the food we consume every day? While digestion would be impossible without enzymes and other proteins, these molecules

D. How does our DNA maintain a double helical structure? While the shape of this nucleic acid is the result of many complex properties, its structures

Option B is correct because it gives a concrete, casually observable example from the natural world and thereby accomplishes the goal. It explains the connection between surface tension and electronegativity.

Option B gives an example from the natural world - the water strider.

The water striders are a good example of insects that use the high surface tension of water and long, hydrophobic legs. This enables them to walk on water. Their legs are coated with a hydrophobic substance. The hydrophobic substance makes the legs to repel water molecules i.e it makes water unable to stick to their legs. This makes them to easily skim on water surfaces.

Answer:

Electronegativity is a measure of the affinity between electrons and atoms.  

When an atom exhibits greater attraction for electrons, it is said to have very high electronegativity.

Electronegativity is an inherent quality that remains constant in all the atoms of an element. Fluorine is the chemical element with the highest electronegativity.  

In nature, the most important element which whose electronegative qualities (or whose ability to bind with other atoms) make it crucial for life is Oxygen.

When we inhale air, the Oxygen is used by our bodies to convert glucose to energy and Carbon Di-Oxide is released.

(3) Rivers still provide viable routes for shipping, but it is no longer the most feasible method for moving materials. (4) As rivers declined in popularity, other shipping methods took their place as the best ways to ship merchandise. Which sentence lacks a logical transition?

Answers

Answer:

3. Rivers still provide viable routes for shipping, but it is no longer the most feasible method for moving materials.

Explanation:

For a sentence to have a logical transition, there must be an accurate subject-verb or subject-pronoun agreement. It as a pronoun can be used as a subject or object in a sentence. When It is used to describe a subject, the subject is usually in the singular form. For example,

1. It is a book.

The sentence, 'Books are a good source of earning, but it is going extinct' is not correct because there is no agreement between the subject which is in the plural form and the pronoun.

So the third sentence should be worded as 'Rivers still provide viable routes for shipping, but they are no longer the most feasible method for moving materials'.

Read the following sentence. Last year, the council members blank happy to visit their sister city in Argentina. Choose the verb that makes this sentence correct. a. were b. are c. was d. is

Answers

The correct answer is A. Were

Explanation:

Verbs should agree with the subject (person or entity doing the action) and they should be in the correct tense (present, past, or future). In this context, the section "Last year" indicates the action of the sentence occurred in the past, and therefore the verb should be in the past. Moreover, in this sentence, the subject is "the council members", which is a plural subject. This means an appropriate verb for this sentence should be in past and plural form. According to this, the only correct option is "were" because this is the past form of the verb to be, it is used for plural subjects, and it creates a coherent sentence.

the rhythm of a piece of poetry or music

a silly or foolish person

meaning, weight, or significance

reward

a small stream

1. "In which the burthen of the mystery, / In which the heavy and the  weary weight of all this unintelligible world, / Is lightened:"

5. "Where was heard the mingled measure. From the fountain and the caves."

Answer:

burthen - meaning, weight, or significance

recompence - reward

loon - a silly of foolish person

rill - a small stream

measure - the rhythm of a piece of poetry or music

Explanation:

Burthen is an archaic form of spelling "burden". When we think of a burden, we think of something heavy, difficult to carry around. Therefore, burthen means "weight"

Recompence is more commonly spelled "recompense" nowadays. It is the same as reward.

A loon is a foolish or silly person. We can think of a "loony", a crazy or silly person, someone who does not think or see things the way others do.

A rill is, by definition, a small stream or brook. There is not much we can add here.

Finally, measure refers to the rhythm of a poem or a piece of music. We commonly refer to it by "meter" or simply "rhythm", depending on what we mean.
