A 30.84 cm-3 volume of 0.128 M NaOH is required to reach the phenolphthalein endpoint in the titration of a 5.441g sample of vinegar .calculate the percent acetic acid in the vinegar.(Molar mass of vinegar is 60.05g/mol)​

Answers

Answer 1

Answer: 4.36%

Explanation:

Here is the complete question:

Calculate the percent acetic acid in vinegar when a 30.84cm^3 volume of 0.128 M NaOH is required to reach the phenolphthalein endpoint in the titration of a 5.441g sample of vinegar.(molar mass of vinegar is 60.05g/mol)

moles NaOH = 0.03084 dm^3 x 0.128

M=0.00395

mass acetic acid = 0.00395 mol x 60.05 g/mol=0.237 g

Percentage of acetic acid:

= 0.237 x 100/ 5.441

= 23.7/5.441

= 4.36%

Why did the gap between the wealthiest and poorest Americans steadily get larger in the decades after 1970?

Answers

Answer:

Since the 1970s, there has been an income inequality in America.

Explanation:

The years from the end of World War II into the 1970s were ones of strong economic growth and prosperity. At the beginning of the 1970s, economic growth reduced, and the income gap increased.

Income inequality has risen steadily among all Americans since the 1970s. In the late 1970s, tax changes, federal monetary policies, deregulation, de-unionization, and other policies reduced wages and employment. Income among the middle and lower parts decreased sharply, while incomes at the top extended to grow strongly.

The Texas Bill of Rights is more specific and discusses more issues. Please select the best answer from the choices provided A B C D

Answers

Answer:

The Correct Answer is D

The Texas Bill of Rights is more specific and discusses more issues.

Explanation:

The United States Constitution forms a unitary executive which strengthens executive power in the president, while the Texas Constitution forms a plural executive which separates executive power across various elected offices, hence, fragmenting the executive branch of the government and restriction of power over the executive

Even though the Texas Bill of Rights provides almost the same protections as the United States Bill of Rights, it extends beyond the federal protections.

Also, the Texas Constitution includes guarantees that are not included in the U.S. Bill of Rights like the prohibition of discrimination based on sex and forbids imprisonment for debt.

The Eastern Front
British blockade
German U-Boats
The Lusitania
The Zimmermann telegram
U.S. declaration of war

Answers

Answer:

The Eastern Front of World War II was a theatre of conflict between the European Axis powers and co-belligerent Finland against the Soviet Union, Poland and other Allies, which encompassed Central Europe, Eastern Europe, Northeast Europe, and Southeast Europe from 22 June 1941 to 9 May 1945.

From the outbreak of war with Napoleonic France, Britain had enforced a naval blockade to choke off neutral trade to France, which the US contested as illegal under international law. To man the blockade, Britain pressed American merchant sailors into the Royal Navy.

U-boat is an anglicised version of the German word U-Boot [ˈuːboːt] (About this soundlisten), a shortening of Unterseeboot, literally "undersea boat".

RMS Lusitania was a British ocean liner that was sunk on 7 May 1915 by a German U-boat 11 miles off the southern coast of Ireland, killing 1,198 passengers and crew. The sinking presaged the United States declaration of war on Germany.

The Zimmermann Telegram was a secret diplomatic communication issued from the German Foreign Office in January 1917 that proposed a military alliance between Germany and Mexico. If the United States entered World War I against Germany, Mexico would recover Texas, Arizona, and New Mexico.

A declaration of war is a formal act by which one state goes to war against another. The declaration is a performative speech act (or the signing of a document) by an authorized party of a national government, in order to create a state of war between two or more states.

Athens was surrounded by rivers, which made it difficult to enter the city.
Athens was located inland, which made it difficult to invade by sea.

Answers

What happened to Athens during the Peloponnesian War?

The war raged for an additional ten years under the Spartan general Lysander. By defeating the Athenian fleet in a battle in 405 B.C., Lysander then put Athens under siege, resulting in its capitulation to Sparta in 404 B.C.

Pericles led Athens' strategy, which called for avoiding direct conflict with the more numerous and better equipped Spartan hoplites in favor of utilizing its superior fleet. The result was that Athens' fleet launched an offensive and triumphed at Naupactus.

Thus, the ideal selection is option B.

10. The philosopher who did not believe in democracy was
a. Alexander
b. Hippocrates
c. Plato
d. Socrates​

Answers

Answer:

C

Explanation:

Plato did not believe in democracy

Final answer:

Plato was the philosopher who did not believe in democracy, instead advocating for a system of government ruled by philosophers. He was skeptical of democracy because he felt it allowed for unqualified majority rule, which could be detrimental to society. His ideals were in contrast to his teacher, Socrates, and continue to influence political thought.

Explanation:

The philosopher who did not believe in democracy was c. Plato. Plato was critical of democracy for several reasons. He saw the democratic process as one where unqualified individuals were given an equal say in public matters as much as the knowledgeable ones. This, he believed, could lead to poor decision-making. He observed that democracy allowed the common opinion of the majority to rule, which might not always work for the best interest of society. Plato's mistrust in democracy was deeply influenced by the death of his teacher, Socrates, who had been sentenced to death by an Athenian democratic jury. Instead, Plato favored a government led by philosophers, whom he deemed as the most suited to rule due to their pursuit of knowledge and wisdom.

Plato's ideal system of government is rule by c. philosophers, as he believed they would govern with the best interests of society in mind, rather than their own personal gain or the erratic whims of the masses. This view is in contrast to the opinion of his predecessors and peers, including Socrates, who also had his own distinct approach to philosophy and engagement with politics.

Historically, there were concerns expressed by both Plato and his student Aristotle about the potential for any given form of governance to devolve into a form that only served the interests of those in power, rather than the common good. Hence, they envisioned ideal forms of governance which to this day still influence political theory and practice.

Explanation:

Read the section "Types Of Myths." Select the paragraph from the article that suggests some gods were able to solve their
problems by creating new beings.
(A) Since each group of people developed their own explanations, mythology differs from culture to culture.
But all myths try to answer basic questions, such as: How was the world created? How did life on Earth
begin? Why is there evil in the world?
(B) Myths explain the origins of Earth in many different ways. Many cultures believe that an all-powerful god
created the world. For example, a myth of the Polynesian people tells that the god lo formed the world
out of water and darkness. People living in the cold lands of what is now northern Europe believed that
the mist was created first. According to the ancient Scandinavian tradition, the mist flowed through 12
rivers and froze, filling the emptiness of the world with many layers of ice, which was later melted by a
warm wind. Other cultures, including the Arapaho of North America, as well as civilizations in Egypt and
Japan, thought of humans as descendants of a sun god.
(C) To explain the origin of human beings, an ancient story from India described a being called the Self
When the Self became lonely, it divided into two parts, creating man and woman. Their children became
the human race. Many myths from western Africa tell that the first beings were a pair of twins. The
Sumerians, an ancient Middle Eastern people, believed that the first people came from clay. According
to their myths, the water god told his mother to mold bits of clay into the shapes of people,
(D) - Many cultures also have myths explaining why there is evil in the world. For example, an ancient Greek
myth tells the story of Pandora, the first woman on Earth. She opened a jar and released all kinds of evil
on the world. A great variety of other myths explain the origins of animals, plants and events in nature.

Answers

To explain the origin of human beings, an ancient story from India described a being called the Self When the Self became lonely, it divided into two parts, creating man and woman is the paragraph from the article that suggests some gods were able to solve their problems by creating new beings. Hence, option C is correct.

What is the myth about the origin of human being?

The world's myths are both quite similar and incredibly distinct. Even though those cultures did not contact when the myths were created, it is possible to conclude that every culture shares certain mythological elements with other cultures from all over the world.

The stories have many things in common, such as trickster deities, the magical voyage and escape, heroes who defeat monsters, magical helpers, either in the form of people or things.

Thus, option C is correct.

dentify and describe two environmental challenges facing Africa. Which challenge do you think needs the most immediate attention? Why?

Answers

Answer:

Deforestation, water pollution, coal mining, nuclear waste, over fishing and industrial agriculture are just a few environmental issues facing Africa, but in my opinion coal mining is the most pressing as it involves other problems like deforestation and water pollution.

Here are a few ways it harms the environment:

Miners clear areas of trees to prepare the land for mining.

Coal mining releases toxic materials into the soil and water.

Bad mining can start coal fires which can burn for decades – releasing “fly ash” and smoke filled with greenhouse gases and toxic chemicals.

It releases coal mine methane which is 20 times more powerful than carbon dioxide.

Strip mining accounts for 40% of the world’s coal mines and the practices destroys landscapes, forests and wildlife habitation. It usually requires mountain blasting and the removal of trees and plants in the mining area.

Coal mining increases the risk of loosening top soils into streams and waterways and the sediments pollute our water and can smother plant life downstream and even kill fish.

Coal has traces of sulfur and nitrogen. When burned, these are released into the atmosphere. While these chemicals are floating in the air, they can mix with water vapor and fall back to earth as Acid Rain.

Coal is made of carbon. When burned, the carbon combines with oxygen and forms carbon dioxide –one of the main contributors to global warming and air pollution.

Aside from carbon, the burning of coal releases sulfur dioxide, nitrogen oxides and mercury compounds into the air.

When rain falls on coal stored in piles outside, the water that comes from these piles will contain heavy metal such as arsenic and lead, which can seep into the land and nearby bodies of water – killing fish and plant life.

Coal dust can cause respiratory problems in humans.

In summary, coal mining has negative effects both in the long run an in the short run.

Since the beginning of 1963, African Americans crushed by violence and other forms of bullying.

Why did the
historian Godfrey Hodgson refer to the
postwar interaction of Republicans and
Democrats as a "liberal consensus"?

Answers

Answer:

After World War II, America was in an economic position that, although recovering from the Great Depression and the effects of the war, needed much social help for both workers and war heroes returned to the civil life. For this reason, American society continued to need some measures of socioeconomic containment, such as those established in the New Deal, to avoid a contraction that could once again harm the quality of life of Americans. These programs were subsequently taken up in programs like Lyndon Johnson's Great Society, which in turn adopted various ideas raised by President Kennedy.

The truth is that not only the Democrats defended these ideas: the Republicans, aware of the need for society, took a surprising turn towards moderation and accepted these measures, giving a "liberal consensus" to guarantee a full economic recovery and avoid a relapse in the middle of the Cold War.
