Rubber is classified under organic or inorganic compound? Reason?

By definition in chemistry, an organic compound is one that contains carbon; entire courses are called Organic Chemistry. They deal solely with substances that contain carbon. Natural rubber is indeed classified as an organic compound.It is formed from sap obtained from rubber trees which grow in tropical or sub-tropical environments. It is a polymer of isoprene. Isoprene is made up of carbon and hydrogen atoms. A polymer is a long strand of repeating sub-units....

By definition in chemistry, an organic compound is one that contains carbon; entire courses are called Organic Chemistry. They deal solely with substances that contain carbon. Natural rubber is indeed classified as an organic compound. It is formed from sap obtained from rubber trees which grow in tropical or sub-tropical environments. It is a polymer of isoprene. Isoprene is made up of carbon and hydrogen atoms. A polymer is a long strand of repeating sub-units.  When the sub-units of isoprene combine in a long chain to form natural rubber the structure ends up coiled, which is what gives rubber its elastic qualities. The second link I have posted below shows the basic structure of isoprene with its single and double bonds between the carbon and hydrogen atoms. It also explains in detail how the units of isoprene link up with others by changing a double bond into a single bond, allowing the link with the next isoprene unit.

In addition to the above, in some instances students are referring not to the presence of carbon (which is the requirement in chemistry for declaring a substance "organic"), but to the source of the materials. "Organic", in common usage, tends to mean something that is found in nature as opposed to those substances formulated artificially. Naturally occurring rubber is formed from tree sap. These days, however, most of the rubber used is either fully or partially formed in a lab/factory. Examples of artificial rubbers are neoprene, Thiokol, BUNA-N and BUNA-S. These rubbers, since they are synthetically derived without carbon compounds, are classified as inorganic compounds. Details of their production and uses can be found in the links after this post.

Who are the major trading partners of modern African nations?

Africa is a large continent with over fifty individual nations. The economic development and trade potential varies from place to place. South Africa is the largest producer of gold and diamonds in the world and trades with most of the developed countries of the West and Asia. Nigeria is the largest oil producer in Africa and is a member of the petroleum cartel of Oil Producing and Exporting Countries. In that capacity, Nigeria is a...

Africa is a large continent with over fifty individual nations. The economic development and trade potential varies from place to place. South Africa is the largest producer of gold and diamonds in the world and trades with most of the developed countries of the West and Asia. Nigeria is the largest oil producer in Africa and is a member of the petroleum cartel of Oil Producing and Exporting Countries. In that capacity, Nigeria is a player in global trade. Many parts of Africa are not well developed and rely on trade for food. The United States has a partnership with Africa that is called Trade Africa. It focuses on traded with sub-Saharan Africa.

Many developed countries have invested a lot of capital to the emerging countries of Africa. Trade with Germany, Japan, and China has had a positive effect on Africa.

The Supreme Court's power of judicial review is not compatible with democratic government. How would you make a persuasive argument from this...

There are many ways to support the argument that the Supreme Court's power of judicial review is not compatible with democratic government. First, the Supreme Court is an unelected body. All justices are appointed by the President, and appointments are approved by the Senate. Thus, the people do not directly vote for Supreme Court justices, which limits the representative character of the Court. An argument could be made that the Court is undemocratic because it...

There are many ways to support the argument that the Supreme Court's power of judicial review is not compatible with democratic government. First, the Supreme Court is an unelected body. All justices are appointed by the President, and appointments are approved by the Senate. Thus, the people do not directly vote for Supreme Court justices, which limits the representative character of the Court. An argument could be made that the Court is undemocratic because it does not represent the interests of the people. Second, the Supreme Court's power of judicial review allows the court to invalidate laws created and implemented by Congress, which is a representative elected body. Congress is the main representation of the people in the U.S. government, and the Court's ability to overturn laws it makes can be seen as an anti-democratic measure, as it is assumed that Congress is enacting the will of the people they represent. Third, the Constitution does not directly give the Court the power of judicial review. Instead, it is an implied power, taken from Articles III and VI of the Constitution. The Constitution is the supreme law of the U.S., and any law that conflicts with the Constitution is null and void. The federal courts are given the duty to interpret and apply the law, thus, they have the implied power to interpret and apply the Constitution (the supreme law of the land). Because the Supreme Court is the highest court with supreme jurisdiction in the U.S., it is the implied duty of the Supreme Court to decide whether laws are consistent with the Constitution. Because the power is not specifically assigned to the Supreme Court in the Constitution, an argument could be made that it is undemocratic in that the Court is assuming powers it was not explicitly assigned. 

What are two things that were significant in the French and Indian War?

There were several significant aspects about the French and Indian War. One aspect was that it led to the French departure from North America. After France was defeated, the French gave all of their land east of the Mississippi River, except for New Orleans, to Great Britain. France also gave all of their land west of the Mississippi River, plus New Orleans, to Spain. As a result, France was no longer in control of land...

There were several significant aspects about the French and Indian War. One aspect was that it led to the French departure from North America. After France was defeated, the French gave all of their land east of the Mississippi River, except for New Orleans, to Great Britain. France also gave all of their land west of the Mississippi River, plus New Orleans, to Spain. As a result, France was no longer in control of land in North America.

Another significant aspect of this war is that it led to a series of events that would eventually lead to Great Britain losing the thirteen colonies they had in what is now the United States. As a result of the French and Indian War, the Native Americans were fearful of what would happen after Great Britain took over the land France previously controlled. There were attacks against British settlements, as evidenced by Pontiac’s Rebellion, and more threats existed. As a result, the British passed the Proclamation of 1763 to keep the colonists safer from attacks.

The Proclamation of 1763 prevented settlement in these newly acquired lands. The colonists were unhappy with this law because they wanted to be able to get ownership of the newly available land. Some colonists refused to follow this law. When the British passed the Quartering Act that required the colonists to provide housing for British troops that would enforce this unpopular law, the colonists became more upset. Later more laws, such as taxes laws like the Stamp Act and Townshend Acts, were passed angering the colonists even more. Thus, what should have been a positive event for Great Britain, the winning of the French and Indian War, turned into a negative event for them, the losing of the colonies after the Revolutionary War.

How does Frederick Douglass's Narrative of the Life of Frederick Douglass, An American Slave, Written by Himself present the subjugation of Blacks...

Douglass shows an uncompromising view of slavery in order to communicate how whites subjugated people of color.

Douglass does not hesitate in his harsh depiction of the institution of slavery. When Douglass speaks about slavery, he presents white subjugation of Black people as criminal:

Douglass shows an uncompromising view of slavery in order to communicate how whites subjugated people of color.

Douglass does not hesitate in his harsh depiction of the institution of slavery. When Douglass speaks about slavery, he presents white subjugation of Black people as criminal:

The more I read, the more I was led to abhor and detest my enslavers. I could regard them in no other light than a band of successful robbers, who had left their homes, and gone to Africa, and stolen us from our homes, and in a strange land reduced us to slavery. I loathed them as being the meanest as well as the most wicked of men.

In using terms like "successful robbers," "stolen" and "meanest," Douglass passes swift judgment against whites who participated in slavery.  He presents the institution and those who perpetrated it as "wicked." 

When confronted with slavery, many people ask the question how it could happen.  How could human beings do that to one another?  Douglass suggests that slavery was like poison that caused people to embrace dehumanizing cruelty.  Douglass highlighted this with the case of Mrs. Auld:

The fatal poison of irresponsible power was already in her hands, and soon commenced its infernal work. That cheerful eye, under the influence of slavery, soon became red with rage; that voice, made all of sweet accord, changed to one of harsh and horrid discord; and that angelic face gave place to that of a demon. 

Mrs. Auld was caring towards Douglass.  She started his advancement education in teaching him how the alphabet. However, her husband rebuked her for this with ideas like ‘‘If you give a nigger an inch, he will take an ell.’  As a result, Douglass saw Mrs. Auld's "angelic face" transform into a "demon."  This is an example of how slavery changed whites by distorting their nature to embrace dehumanizing cruelty in their subjugation of people of color.

In "A Good Man Is Hard To Find," what is the character change in the grandma throughout the story?

In Flannery O'Connor's "A Good Man is Hard to Find," the grandmother is the central character in the story. Though her personality does not change throughout the story, her presence does. She remains throughout the story, an opinionated old woman who is disrespected by her son and his family. However, at the beginning of the story, she takes a backseat (figuratively and literally) in the family. She doesn't say much and tries not to annoy...

In Flannery O'Connor's "A Good Man is Hard to Find," the grandmother is the central character in the story. Though her personality does not change throughout the story, her presence does. She remains throughout the story, an opinionated old woman who is disrespected by her son and his family. However, at the beginning of the story, she takes a backseat (figuratively and literally) in the family. She doesn't say much and tries not to annoy her grown son. Though she makes small comments here and there, she knows her place.

Later, once the Misfit has the family on the side of the road in the woods, the grandmother takes a dominant role in the family since Bailey has become helpless and wordless. It is the grandmother who tries to talk her way out of the situation. She becomes voluble as she desperately tries to reason with the Misfit or convince him that he is a 'good man' and should let them go. So the real change in the grandmother occurs in her shifting role from a background character to a primary voice of the family. Because Bailey has gone from the controlling son and head of the household to a diminished person, sitting helplessly while the Misfit is about to kill them, the grandmother must step forward and take a more active role, which is a complete reversal from how readers saw her at the start of the story.

One strand of DNA has the nucleotide sequence AACGTA. What is the sequence of the other strand?

In a strand of DNA, the nitrogenous bases used to make up the "rungs" of the double-helix ladder are cytosine, guanine, adenine, and thymine.  These bases may be abbreviated cytosine (C), guanine (G), adenine (A), and thymine (T).  The bases pair up cytosine to guanine, while adenine pairs up to thymine.  When DNA replicates, the bases split right down the middle of the double-helix, providing a template for new DNA to be assembled.  If the...

In a strand of DNA, the nitrogenous bases used to make up the "rungs" of the double-helix ladder are cytosine, guanine, adenine, and thymine.  These bases may be abbreviated cytosine (C), guanine (G), adenine (A), and thymine (T).  The bases pair up cytosine to guanine, while adenine pairs up to thymine.  When DNA replicates, the bases split right down the middle of the double-helix, providing a template for new DNA to be assembled.  If the DNA is as given, AACGTA, the corresponding DNA sequence that would be complementary would be TTGCAT.  This base sequence would pair correctly, using the established DNA code as a template.  Each set of three bases is a set called a codon.  There are two codons in this given DNA sequence, AAC and GTA.  The corresponding codons that correctly match up to those two are TTG and CAT.
