## A second reaction mixture was made up in the following way: 10 mL 4.0 M acetone + 20 mL 1.0 M HCl + 10 mL 0.0050 M I2 + 10 mL H2O a. What were the initial concentrations of acetone, H+ ion, and I2 in the reaction mixture? (acetone) ___________ M; (H+) ___________ M; (I2)0 ___________ M b. It took 120 seconds for the I2 color to disappear from the reaction mixture when it occurred at the same temperature as the reaction in Problem 2. What was the rate of the reaction?

A. We can calculate the initial concentrations of each by
the formula:

initial concentration ci = initial volume * initial
concentration / total mixture volume

where,

total mixture volume = 10 mL + 20 mL + 10 mL + 10 mL = 50
mL

ci (acetone) = 10 mL * 4.0 M / 50 mL = 0.8 M

ci (H+) = 20 mL * 1.0 M / 50 mL = 0.4 M               (note: there is only 1 H+ per 1 HCl)

ci (I2) = 10 mL * 0.0050 M / 50 mL = 0.001 M

B. The rate of reaction is determined to be complete when all of I2 is consumed. This is signified by complete disappearance of I2 color
in the solution. The rate therefore is:

rate of reaction = 0.001 M / 120 seconds

rate of reaction = 8.33 x 10^-6 M / s

## Why, in light of all the problems that occurred in tenement living, so many people continued to move into cities

I’m assuming you’re talking about how cities such as New York and Chicago were overpopulated and held horrible living conditions, especially for workers there.

Well, simply, cities offered better resources no matter what. If you lived in the country, whatever you produced was based on the outdoor elements, but you had to deal with isolation of many people and institutions such as schools, doctors, ect. In the city, yes it was overpopulated and work conditions were terrible, but people had a mindset that better work for a penny that you know that you’ll get instead of hoping a dollar that can disappear because of a bad harvest year.

## Which of the following statements describes the Industrial Revolution? a. It was quick and violent and produced few results. b. It took place mostly in rural areas among farmers. c. It depended largely on the development of the factory system. d. It occurred because of years of planning in the United States in the mid-1700s. Please select the best answer from the choices provided

The answer is C. In order to carefully control conditions and confirm or disconfirm a hypothesis about the causes of behavior, one must perform an experiment.

Explanation:

Experimental research allows the researcher to control all the variables in order to create the conditions that can confirm or disconfirm a hypothesis. This method aimes to establish a relation of causality between two variables, which means that one variable is generated and determined by the other; this is posible because all of the other variables that can influence it have been controlled.

When a researcher conducts a survey or engages in naturalistic observation, he can’t control the variables, therefore, he can only establish a correlation between two variables, but not of causality.

## What was the primary reason for the economic boom that occurred in the United States after World War II? It wasn’t necessary to rebuild land and industries. It was necessary to rebuild land and industries. The Marshall Plan provided money to develop industries. The European Union provided money to develop industries.

The Reformation actually started after Columbus’s landing in North America.

Treaty of Tordesillas in 1494 was forced on Spain and Portugal by the Pope. The Pope basically said that all lands in the New World belonged to Spain and all new non-Christian lands in the Eastern Hemisphere belong to Portugal. No other Catholic countries can do anything in those areas without the approval of the owner.

The pope basically drew two lines on the globe setting the border. The western line started at the north pole cut half way through Greenland and ended at the south pole. The new world was everything to the west. Problem is that it ran through a chunk of Brazil which is why Brazil is an ex-Portuguese colony.

The Eastern line starts at the North Pole runs through siberia, through the pacific just west of Japan, and cuts Australia in half. Of course, Australia hadn’t been discovered yet. Everything to the the east of this line is the new world.

Obviously, this treaty didn’t hold up well, but the reformation gave the protestant countries an excuse to explore the new world since they didn’t have to take orders from the Pope. Even so, France, a catholic country, ignored it too.

Really, the only country that was effected by the reformation in the exploration of the Americas was England. All the other countries, changed their religion once and then went to war with the nearest catholic country. Sweden became Lutheran and stayed that way. The Dutch Republic became Calvinists and stayed that way.

England kept switching. First it was Catholic. Then, Henry VIII made it protestant. Then, Henry’s daughter Mary I made it catholic again. Henry’s other daughter Elizabeth I (with the two hit movies) made it Protestant again.

Years latter, Oliver Cromwell over through the monarchy, executed the King Charles I, and established a Protestant fundamentalist religious military dictatorship. He outlawed drinking,smoking, gambling, theater, dirty books, sports, prostitution, and anything generally fun. He would have made Saudi Arabia proud. Basically, all you could do is work, pray, and die. Sex was allowed for creating children, but you couldn’t enjoy it.

When Cromwell died, the people of England said enough was enough and brought back the King. Charles II kicked out the fundamentalists and brought back drinking, smoking, gambling, dirty books, sports, prostitution, and having fun during sex. Incidentally, those were also all his hobbies.

This brings us to the famous Pilgrims. They were part of Cromwell’s crowd. They kept agitating a return to the no-fun policy. They annoyed everybody. They weren’t persecuted for practicing their religion, they were persecuted because they kept trying to force their religion on everyone else. Sort of like Southern Baptists.

Charles II was the most easy going monarch in British history. Do realize how annoying you have to be to get him to throw you out.

Charles’s brother James II was obsessed with turning Great Britain catholic again. After four years of trying, they kicked him and his followers out.

## List five domestic events that occurred in the United States during 1945 through 1950

Here are the following effects of loose money and tight
money policies on the actions being listed.

A. A loose money policy
is usually implemented as an effort to encourage economic growth.
This can lead to inflation when uncontrolled. The effects are:

1. Borrowing becomes easy

3. Since more people are willing to buy,

4. Employment rate increases due to

5. Since more people are employed, thus
production also increases

B. A tight money policy is a course of action to restrict spending
in an economy that is growing too quickly or to hold back inflation when it is
rising too fast. This can lead to recession when uncontrolled. The
effects are:

1. Borrowing becomes difficult

3. Since people don’t have a lot of

4. Unemployment rate increases due to businesses
slowing down

5. Production decreases

## How did shifting workforce demographics contribute to the dramatic changes that occurred in the US labor force and industry during and immediately after World War II? Please help. I have to write an essay on this question and I don’t understand. :(

Industrialization led to rising imperialism because
1) show of power: As one makes new technology, they would either want to test it out or show the other nations that what they produce is ground-breaking and the best. Usually if it is military technology, you would want to test it out, and with the use of “show of force”, can have people groups submit to your country.
2) Better technology: As technology advances, it usually makes something easier. In the case of imperialism, better military advances meant that they could (once again) have other people submit to you
3) Better transportation: This meant that you could take multiple countries at once, and can prove that you’re country is great by having supplies shipped over long distances to keep your troops up. If in need of more troops, you could send more.

## The end of chromosome 14 breaks off and attaches to chromosome 4. Which chromosomal mutation occurred?

25) Answer is: less metallic and more nonmetallic.

Electronegativity increases from left to right across a period, atoms have tendency to attract electrons.

Electronegativity (χ) is a property that describes the tendency of an atom to attract a shared pair of electrons.

Radioisotope has an unstable atomic nucleus and emit energy and particles when it changes to a more stable form.

Francium (Fr) is element with atomic number 87 (87 protons and 87 electrons).

Boiling is the temperature at which the vapour pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding atmosphere.

The Celsius scale was based on 0°C for the freezing point of water and 100°C for the boiling point of water at 1 atm pressure.

There are two types of reaction:

1) endothermic reaction (chemical reaction that absorbs more energy than it releases, ΔH>0).

2) exothermic reaction (chemical reaction that releases more energy than it absorbs).

For example, the breakdown of ozone is an endothermic process. Ozone has lower energy than molecular oxygen (O₂) and oxygen atom, so ozone need energy to break bond between oxygen atoms.

The average kinetic energy of molecules depends on the temperature.

As temperature increases, molecules gain more energy from surrounding and move faster.

Kinetic energy (standard unit is the joule J) depends on speed of the molecule.

Solid gains kinetic energy to become a liquid and then becomes a gas.

This was famous Rutherford’s Gold Foil Experiment: he bombarded thin foil of gold with positive alpha particles.

Rutherford observed the deflection of alpha particles on the photographic film.

Alpha particles are helium atom particles, consist of two protons and two neutrons.

According to Rutherford model of the atom: atoms have their charge concentrated in a very small nucleus.

For example, calcium oxide.

Calcium oxide (CaO) has ionic bonds between calcium cations (Ca²⁺) and oxygen anions (O²⁻).

Because it has strong ionic bonds, it has high melting point (around 2600°C).

Ionic bond is the electrostatic attraction between oppositely charged ions (cations and anions).

32) Answer is: a scientific model.

A scientific model is a representation of an idea, an object, a process or a system that is used to describe and explain phenomena that cannot be experienced directly.

33) Answer is: the superscript is mass number and the subscript is atomic number.

Atomic number(Z) is the number of protons, which is characteristic of a chemical element..

Mass number (A) is the total number of protons and neutrons in a nucleus.

## Enzo read this passage from “The Smithville Gazette: Neighborhood Thief Strikes Again.” Another episode in the recent spate of neighborhood thefts occurred on Saturday at Ferguson’s department store. Several pieces of jewelry were taken at approximately 12:30 in the afternoon. Mrs. Jane Dickson, the employee working the jewelry counter reported that she did not initially see the theft, but realized shortly before 1 p.m. that several necklaces were missing from inside the jewelry case, which she had accidentally left unlocked while moving away to help another customer. Instead of taking notes on the central idea, Enzo copied the passage down exactly. What is the best way to revise the passage into notes that reveal the central idea? a) Saturday @ 12:30 p.m., Ferguson’s, Mrs. Jane Dickson, jewelry, necklaces b) robbery @ Ferguson’s jewelry on Sat.—necklaces stolen c) On Saturday at Ferguson’s, there was a robbery and some jewelry was stolen. d) Mrs. Jane Dickson says there was a jewelry robbery.

Hey there!

Correct answer is D. Comma or Period Inside Rule

A. Question mark or exclamation point inside: those are not really necessary.

B. Colon or semicolon: not, a semicolon would divide the whole sentence and it would be shorten; a colon would work but after requested, when there is already a comma.

C. Question mark or Exclamation Point Outside Rule: would not work, becase it is an very polite and affirmative sentence.

D: A comma or period inside rule: actually, just a comma would work. Please, Cooper’s dad requested, go… Cooper’s dad requested must be in between commas as it is a vocative.

## In two or more complete sentences, compare the number of x-intercepts in the graph of f(x)=x2 to the number of x-intercepts in the graph of g(x)= (x+2)2 +7. Be sure to include the transformations that occurred between the parent function f(x) and its image g(x).

False

Step-by-step explanation:

Suposse that we are given a function f(x) and a constant value h.

1. Case:

If we take the function g(x)=f(x)+h, then the graph of the function g(x) will be the graph of the funcion f(x) moved up or down.

2.Case:

If we take the function g(x)=hf(x), then the graph of the function g(x) will be the graph of the function f(x) just taller or shorter.

3.Case:

If we take the function g(x)=f(x-h), then the graph of the function g(x) will be the graph of the fuction f(x) moved horizontally.

4. Case:

If we take the function g(x)=f(hx), then the graph of the function g(x) will be tha graph of the function f(x) wither or thiner.

For example:

If we take f(x)=sin(x) and h=2. Then, if we take g(x)=sin(2x) then f(0)=g(0)=0, which means that the graph of the functiction is not moved up or down. However, f(π/2)=sin(π/2)=1 and g(π/2)=sin(π)=0 which gives us a hint that the graph of the function became thiner.

## Congress could not impose or collect taxes Congress could not regulate interstate commerce or foreign trade There was no executive branch to enforce the laws of Congress This list of notes would be MOST useful to a student writing a research paper about A) the ineffectiveness and weakness of American government under the Articles of Confederation. B) the factors behind the unrest and violence that occurred in Shay’s Rebellion and the Whiskey Rebellion. C) the reasons for the Anti-federalists’ demand for the inclusion of the Bill of Rights in the U.S. Constitution. D) the emergence of political division and the eventual creation of the “two-party” system in American government.

C) Nations begin to rely on each other for things they cannot produce themselves.

Explanation:

Globalization can lead to interdependence among nations. One of the most common ways in which this happens is through free trade. When two countries trade, they exchange goods and services. If the relationship is long and stable enough, the population can come to rely on the other country’s goods, which might not be produced in their country, or might be produced at a much higher price.

## What is one way that the post-war reform movements in the British and French colonies might be different if they occurred today? Organizers would make use of social media, such as Facebook, to organize and unify. The movements would be struck down more violently because the British and French governments are more powerful. Reformers would not have demanded change because British and French economies are more stable. Fewer people around the world would be aware of the reformers and their calls for change.

3. The answer is “D.  showing a learner how to correct common mistakes”.

The term scaffolding alludes to a procedure in which instructors display or exhibit how to take care of an issue, and afterward venture back, offering support as required. Analyst and instructional architect Jerome Bruner first utilized the term ‘scaffolding’ in this setting, harking back to the 1960s. The hypothesis is that when understudies are given the help they require while discovering some new information, they stand a superior possibility of utilizing that learning freely. Bruner suggests positive association and three methods of portrayal amid educating: activities, pictures, and dialect.

## The cell cycle produces daughter cells that _________ select one: a. are genetically identical to the parent cell (assuming no mutation has occurred). b. have the same number of chromosomes as the parent cell but not the same genetic content. c. have a random assortment of maternal and paternal chromosomes. d. have the same number of chromatids as the parent cell had chromosomes. e. none of the above.

The correct answer to this would be:

“inability of many medium ground finches to feed on large,
hard seeds”

The medium ground finches feed on seeds. However, the birds
have two variations in the bill shape: some birds have wide, deep bills while others
have thinner bills. The large-billed birds feed more proficiently on large,
hard seeds, while the smaller billed birds feed more proficiently on small,
soft seeds. The reduction in number started in 1977, when a drought period
altered vegetation on the island. Due to this event, the number of seeds
declined dramatically; the decline in small, soft seeds was larger than the
decline in large, hard seeds. The large-billed birds were able to endure better
than the small-billed birds thus resulting in decline in number.

There are two systems in the human body that are responsible for the coordination between the functions of different systems to achieve the unity of the living organism’s body. These two systems are the nervous system and the endocrine system. The action of the nervous system is fast and takes a short time, while the action of the endocrine system is slow and takes a long time.

The functional unit of the nervous system is the nerve cell or the neuron. The neuron consists of a cell body and the axon. The cell body starts with the dendrites that receive the messages or the impulses from other neurons or from different sense organs or receptors. These impulses are then transmitted through the cell body. The cell body contains a nucleus and different organelles which help the nerve cell to perform its functions. The nerve impulse is then transmitted to the axon.

The axon is an extension from the cell body. There are some cells called Schwan cells that secrete a myelin sheath to insulate the axon from the surrounding medium. The insulated axons have more ability to conduct the impulses than non-insulated axons. The axon ends with the terminal arborizations. The terminal arborizations of a nerve cell connect to the dendrites of the next cell or to the afferent organ. The gaps between the dendrites and the terminal arborizations are called the synapses.

The nerve impulse is an electrochemical phenomenon i.e. an electrical phenomenon with a chemical nature. The membrane of the axon acts as a barrier between an outside positively charged medium and an inside negatively charged medium. This makes a potential difference of  -70mV. This state is called the resting potential. When the membrane is subjected to a stimulus, the positive charges enter to inside and the negative charges exit to the outside. The potential difference now becomes +40mV. This state is called the depolarization state. The point of stimulation acts as a new stimulus for the next point and so on. The membrane sooner gains its permeability again and the positive charges return to the outside and the negative charges to inside. This state is called repolarization.

The nerve impulse reaches the synapse. There are some neurotransmitters that are excited by the nerve impulse coming and carry the message across the membrane. Some receptors receive theses neurotransmitters on the dendrites of the next neuron. These receptors act as a stimulus for the new cell.

The error in grammar: it help

Correct verb form: it helps

Explanation:

In the simple present tense, third-person singular pronouns, like she, he and it, use conjugated verbs formed by the base form of a verb and the affix -s, -es, or -ies. For example: helps, thinks, cries, watches. In the excerpt provided, the error is in the verb help because it is not correctly conjugated for the pronoun it: it is missing an s at the end.

Bruner suggests positive association and three methods of portrayal amid educating: activities, pictures, and dialect.

The function of the noun clause in this sentence is a subject.

A noun clause is a group of words working together as a noun. These clauses are always dependent clauses so that, they do not form a complete sentence. Noun clauses are used to name something when a single word isn’t enough. These can be noticed by seeing the following words: How, that, what, who, why, whoever, whatever, when, where, wether, which, whichever, who, whoever, whom.

## When the amount of a radioactive substance is reduced by half, what has occurred?

In
order to calculate an average, we should sum all numbers and divide them by
quantity.

Let’s
work with qualifications first. Let’s say you got a 10 in 1 exam, then an 8 in
2 exams and a 4 in 2 exams. Your average will be:

=
(10*1+8*2+4*2) / 5 = 6.8

If
6 is the minimum, you will pass.

There
is another way to calculate this average: applying distributive property.

=
10*1/5+8*2/5+4*2/5 = 6.8

Remember
you can convert the fractions into equivalent fractions: 1/5 = 20/100; 2/5 =
40/100

=
10*20/100+8*20/100+4*20/100 = 6.8

We
actually don’t have the number of atoms of each mass… we have the percentage
instead! So we need to learn this last method for atoms.

Let’s
go back to our atoms problem:

99.59% of atoms have a
mass of 39.96 u

0.065% of atoms have a
mass of 37.96 u
0.336% of atoms have a
mass of 35.97 u

So let’s put that in the
formula:

Average mass = 39.96u*99.59/100
+ 37.96u*0.065/100 + 35.97u*0.336/100

So what you have to know
is that a percentage can be converted into a fraction, and you should work that
fraction in order to find the average.
We can make the calculus
shorter putting 100 as the common denominator:

Average mass = (39.96u*99.59
+ 37.96u*0.065 + 35.97u*0.336)/100

So actually we are taking
the percentage as if it was the quantity, and 100 as if it was the total (the
total of all percentages is always 100). Maybe we don’t have 100 atoms, but it
will be the same proportion anyway, whatever number we have!
And here it is the result:

Average mass = 39,94 u
