The transition metal group of the periodic table exhibits a wide array of different colored compounds. The complex ion tetraamminecopper(II) contains four ammonia molecules covalently bonded to a copper(II) ion. In aqueous solutions, Cu2+ ions will bond to four water molecules in a square planar geometry. The solution is a light blue color.

Solution
Formula:
Transmittence= 10^(-Absorbance)
T=10^(-A)
T=10^-1.5
T=0.031623
%T=3.1623%
This means that 96.8377% light has been absorbed and only 3.1623% has been transmitted. Detection of such low value of transmitted by the detector will increase the chances of error. Also, because transmittence decreases logarithmically, linearity is lost at high concentration of sample.

Arrange the following elements from greatest to least tendency to acce.docxvtuan3
Arrange the following elements from greatest to least tendency to accept an electron.
Mg, Si, Na, S, Cl
Solution
The ability to accept one or more electrons is known as electron affinity.
The halogens( Group 7A) have the highest electron affinity values because by accepting an electron makes a stable noble gas configuration. Hence, Cl has greatest tendency to accept an electron.
The valence electron configuration of the Mg metal is 3s2. The extra electron must enter the 3p subshell, which is effectively shielded by two 3s electrons ( Because ns electrons are more penetrating than np electrons) and the inner electrons. Consequently, Mg metal has little tendency to pick up an extra electron.
Hence, Mg has least tendency to accept an electron.
The valence electron configuration of the Na metal is 3s1. The extra electron must enter the 3s subshell, which is stable as it fulfills the s orbital. Hence, Na has greatest tendency to accept an electron than Mg.
From left to right electron affinity increases. Hence, S > Si
Therefore, the order of accepting an electron from greatest to least is as follows:
Cl (349 kJ/mol) > S (200 kJ/mol) > Si (134 kJ/mol) > Na (53 kJ) > Mg (<(=) 0).

Arrange the elution sequence of the following compounds by using reversed phase liquid chromatography (1st , 2nd ,3rd)
Glucose, Cholesterol, Lauric aicd
Solution
Reversed Phase Liquid Chromatography is a chromatographic technique in which the mobile phase used is more POLAR than the NON-POLAR stationary phase. Thus hydrophilic molecules will be eluted first followed by hydrophophobic compounds.
The molecules that we are considering are Glucose, Cholesterol and Lauric acid
1. Glucose: it is considered a polar molecule. The presence of oxygen atoms around the molecule in the form of -OH group will ensure the hydrophilic nature of compound.
2. Cholesterol: it is a 27-Carbon organic compound that belongs to the category of steroids. The only polar component present in the molecule is the single -OH group attached to the ring. it is counted among the group of non-polar molecule
3. Lauric acid: Lauric acid is a 12-carbon fatty acid which contains a long chin of hydrophobic group attached to the terminal polar -COOH group. It is considered to be more polar than cholesterol but it is altogether a non-polar compound due to long hydrophobic chain.
As per the nature of the compounds, the sequence in which the compounds will be eluted in the reversed phase liquid chromatographic column is
1. Glucose 2. Lauric acid 3. Cholesterol

Are you surprised by the variety and range of issues addressed by the.docxvtuan3
Are you surprised by the variety and range of issues addressed by the World Bank - projects that meet basic needs such as fresh water and programs to provide Internet services? What are your thoughts on this variety?
Solution
Soln:
It is indeed surprising by the variety and range of issues addressed by the World Bank. There are concerns about the types of development projects funded. Many infrastructure projects financed by the World Bank Group have social and environmental implications for the populations in the affected areas and criticism has centred on the ethical issues of funding such projects. For example, World Bank-funded construction of dams for irrigation, drinking water and electricity generation in various countries has resulted in the displacement of indigenous peoples of the area.
World Bank working in partnership with the private sector may undermine the role of the state as the primary provider of essential goods and services, such as Internet service, drinking water, healthcare and education, resulting in the shortfall of such services in countries badly in need of them.
Therefore , world bank should focus more on providing funding to alleviate proverty and to take up projects which empower people to come out of poverty and world bank should not impose any conditionalities on governments who borrow money from them.

Are there ethical considerations we should consider during the the ent.docxvtuan3
Are there ethical considerations we should consider during the the entire innovation process? If so, what are they? Do they occur at every step of the process? Can an innovation be morally neutral, yet be unethical or socially irresponsible when carried out or applied?
Solution
The words innovative and innovation
are bantered about in the media, in
business, and in our everyday lives. The
words evoke a feeling of progress with
technology moving us upward and
forward while simultaneously pushing
aside existing, soon-to-be-outdated,
technology. How does business handle
this disruption? How can we think about
the responsibility for the innovation and
the associated wake of changed beliefs,
behaviors, and relationships?
The goal of innovations is to upset
current beliefs, behavior, relationships,
and technologies for a given community.
The automobile disrupted the horse and
buggy system. The telegraph disrupted
the Pony Express
By viewing the innovative process
as bringing together technology and
communities, the innovation and
its consequences become a shared
responsibility. The community has a
responsibility to use the technology
within a given range of permissible
behaviors and to incorporate rules
and norms to support the technology.
The innovating firm, however, has
a responsibility to understand the
community into which the innovation
is being introduced.

innovators in the United States,

Solution
Answer 24.) Sickle cell anemia is an inherited form of anemia in which there aren\'t enough healthy red blood cells to carry adequate oxygen throughout your body. Sickle cell anemia is caused by a mutation in the gene that tells the body to make the red, iron-rich compound that gives blood its red color (hemoglobin). Hemoglobin allows red blood cells to carry oxygen from your lungs to all parts of your body. In sickle cell anemia, the abnormal hemoglobin causes red blood cells to become rigid, sticky and misshapen. After the hemoglobin molecules give up their oxygen, some of them may cluster together and form long, rod-like structures that become stiff and assume a sickle shape. The sickle cell gene is passed from generation to generation in a pattern of inheritance called autosomal recessive inheritance. Two genes for the sickle hemoglobin must be inherited from one\'s parents in order to have the disease. A person who receives a gene for sickle cell disease from one parent and a normal gene from the other has a condition called \"sickle cell trait.\" Sickle cell trait produces no symptoms or problems for most people. Sickle cell disease can neither be contracted nor passed on to another person.

Answer the below in your own words- What were the reasons for the deco.docxvtuan3
Answer the below in your own words:
What were the reasons for the decolonization movement after WWII?
Solution
The Second World war greatly weakened European colonial rule, forcing the allies to abandon many of their colonial possessions in the face of invasion.
When the European powers tried to return to rule again they found that the local nationalists had encouraged the population to reject European rule in favor of self-determination. A good example of this was Indonesia where the Dutch had ruled for over 150 years. In 1948, Indonesia declared Independence, and Netherlands found themselves without any support.
Another reason was that when the war ended, one of the themes of the United Nations was encouraging self-determination and ending colonial rule, which was one of the main causes of the First World War.
But i think that the most important factor is that the world, particularly the United States, refused to help or support European powers re-establish colonial rule. One of the reasons for this was that the U.S saw European colonial rule as deterimental towards its own global economic aspirations.
A good example of this was the U.S attitude towards Britain, which had used the Imperial system to exclude the U.S from favourable trade with Australia, Canada, and New Zealand.
The U.S was also reluctant to use money and manpower to fight guerilla wars to support European rule. The U.S was more than aware that the world would also reject any war fought to uphold colonial rule. When the nationalists in Vietnam tried to overthrow French rule, the French had no allies and lacked general support.
Another reason was that with the spread of communism in Europe and SE Asia, the U.S was more than aware that European colonial rule provided fertile ground for anti-European sentiment, which invited communist sympathies.

Answer in your own words- Would you agree with Karl Marx in saying tha.docxvtuan3
Answer in your own words:
Would you agree with Karl Marx in saying that the Industrial Revolution and its capitalistic foundations negatively affected the working classes?
Solution
The Industrial Revolution advance capitalism to its final stage, which Marx saw as an ultimate evil. Before the industrial revolution feudalism existed which is a society run by land owners when the aristocracy gives land to the peasants and those landowners scrape and consume the profit the peasants make by taxation and taking of food using the knights as the collectors. Financial capitalism was a growing idea taken from the Greeks and Romans who believed that most individuals had a right to sell things to gain profit and to run businesses. This idea was reintroduced to Europe during the Renaissance, but it was still applied using feudal methods. The American and French revolution helped strengthen capitalism and the end of the great French war made England one of the richest nations in the world. Advances in technology and new inventions brought about the Industrial Revolution. The Idustrial Revolution created factories and housing for the peasants and it created a better market and made intelligent men big business men who exploited hundreds making themselves very wealthy. Because of the system lots of money could be made buying labour to make products that could be sold to other workers. Marx saw this new capitalism as unfair where the intelligent ruled the poor and created a new aristocracy who made workers got to work doing a job that was degrading, unfulfilling and where you were not paid a fair wage to make a living. So he came up with the idea of communism where capitalism is destroyed as is any other type of inequality and where the state and all institution disappear. so the Industrial Revolution not only gave birth to progress, wealth and democracy it also gave birth to communism.

Analyze the role of credit rationing in both a developed country and a.docxvtuan3
Analyze the role of credit rationing in both a developed country and a less-developed country. How does the role of credit rationing influence economic growth and employment in these two countries?
Solution
Credit rationing is an action taken by lending institutions to limit or deny credit based on a borrowers\' creditworthiness and an overload of loan demands. Interest rates trending either up or down lead to credit rationing. An example of credit rationing is increasing interest rates about current market rates. Credit rationing IS a pervasive phenomenon. There are two different forms of quantity constraints:
micro credit rationing, this places credit limits on borrowers,
and macro credit rationing, this randomly denies access to any credit to a fraction
of borrowers. The second form has asymmetric treatment of otherwise identical
agents. Both forms of rationing can coexist, and play complementary
yet distinct roles. It becomes clear that the second form of rationing gains in
importance when the information flow within the lending community is poor (thus
defaulters have a fair chance for escaping detection).
One lesson that comes from both debt overhang and enforcement theories is
that the distribution of bargaining power among lenders and borrowers has strong implications
for the degree of credit rationing, effort levels as well as efficiency. The effect is
similar in both cases

Encapsulation process. Explain this process giving specific detail at each layer of the OSI Model. Be sure to explain the different PDUs at each stage and include the most significant fields for each pdu.
(20 marks)
Solution
Its dvided into seven layers. Encapsulation happens seperately at different levels.
Starting frm Application layer, application running on source device creates some kind of data.Then next comes Presentation layer where encryption gets added to the data. Then the session layer where session id is applied.Upto this point information is still one block of data. Next layer is transport layer where bock of data gets break down into segments and gets a port number. This segment is then passed to Network layer where source and destination IP address are appended and now the segment becomes packet.This packet is then passed to next level called Data link layer where destination MAC address and CRC is added.Now the resulting thing is Frame. The Frame then is sent to the physical device where it is translated into some kind of a signal, whether it’s electrical, radio wave, light or other signal. This Frame then becomes some kind of a signal that represents a series of zeros and ones. This is why at the Physical layer we often call it Bits

Here, Cash will decrease & Utilities expense will increase.
Revenues & Expenses are part of Owners equity (Under Retained earnings component, related as: Ending Retained earnings = Beginning Retained earnings + Revenue - Expenses - Dividends). So:
Cash (Current Asset) will decrease & Owner\'s Equity will decrease.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

compound. The transition metal group of the periodic table exhibits a wide array of different
colored compounds. The complex ion tetraamminecopper(II) contains four ammonia molecules
covalently bonded to a copper(II) ion. In aqueous solutions, Cu2+ ions will bond to four water
molecules in a square planar geometry. The solution is a light blue color. The water molecules
can be displaced by ammonia mol- ecules, which form more stable complex bases than water.

Solution
Formula:
Transmittence= 10^(-Absorbance)
T=10^(-A)
T=10^-1.5
T=0.031623
%T=3.1623%
This means that 96.8377% light has been absorbed and only 3.1623% has been transmitted.
Detection of such low value of transmitted by the detector will increase the chances of error.
Also, because transmittence decreases logarithmically, linearity is lost at high concentration of
sample.
