The correct answer is B. Atoms of the same element are always identical.

Explanation:

John Dalton was an English chemist mainly known for proposing the atomic theory during the 18th century, in this theory Dalton proposed multiple laws related to the atoms, which are the smallest units of matter and they way these behave including that the mass of the elements remains constant through the chemical reactions and that each element is composed by atoms with identical features which means atoms of different elements are different and can not be changed but only combined using different ratios or proportions. Considering this, it can be concluded Dalton's atomic theory included the idea that atoms of the same element are always identical.

How does this Declaration of Rights represent a new attitude for black Americans of the early 20th century?
lina2011 [118]

Answer:

The problem for African Americans in the early years of the 20th century was how to respond to a white society that for the most part did not want to treat black people as equals. Three black visionaries offered different solutions to the problem.

Booker T. Washington argued for African Americans to first improve themselves through education, industrial training, and business ownership. Equal rights would naturally come later, he believed. W. E. B. Du Bois agreed that self-improvement was a good idea, but that it should not happen at the expense of giving up immediate full citizenship rights. Another visionary, Marcus Garvey, believed black Americans would never be accepted as equals in the United States. He pushed for them to develop their own separate communities or even emigrate back to Africa.

Booker T. Washington

Booker T. Washington was born a slave in Virginia in 1856. Early on in his life, he developed a thirst for reading and learning. After attending an elementary school for African-American children, Washington walked 500 miles to enroll in Hampton Institute, one of the few black high schools in the South.

Working as a janitor to pay his tuition, Washington soon became the favorite pupil of Hampton's white founder, General Samuel Chapman Armstrong. Armstrong, a former Union officer, had developed a highly structured curriculum, stressing discipline, moral character, and training for practical trades.

Following his graduation from Hampton, for a few years Washington taught elementary school in his hometown. In 1880, General Armstrong invited him to return to teach at Hampton. A year later, Armstrong nominated Washington to head a new school in Tuskegee, Alabama, for the training of black teachers, farmers, and skilled workers.

Washington designed, developed, and guided the Tuskegee Institute. It became a powerhouse of African-American education and political influence in the United States. He used the Hampton Institute, with its emphasis on agricultural and industrial training, as his model.

Washington argued that African Americans must concentrate on educating themselves, learning useful trades, and investing in their own businesses. Hard work, economic progress, and merit, he believed, would prove to whites the value of blacks to the American economy.

Washington believed that his vision for black people would eventually lead to equal political and civil rights. In the meantime, he advised blacks to put aside immediate demands for voting and ending racial segregation.

In his famous address to the 1895 Cotton States and International Exposition in Atlanta, Georgia, Washington accepted the reality of racial segregation. He insisted, however, that African Americans be included in the economic progress of the South.

Washington declared to an all-white audience, "In all things social we can be as separate as the fingers, yet one as the hand in all things essential to mutual progress." Washington went on to express his confidence that, "No race that has anything to contribute to the markets of the world is long in any degree ostracized [shut out]."

White Americans viewed Washington's vision as the key to racial peace in the nation. With the aid of white philanthropists such as Andrew Carnegie, Washington's Tuskegee Institute and its philosophy of economics first and equal rights later thrived.

Recognized by whites as the spokesman for his people, Washington soon became the most powerful black leader in the United States. He had a say in political appointments and which African-American colleges and charities would get funding from white philanthropists. He controlled a number of newspapers that attacked anyone who questioned his vision.

Washington considered himself a bridge between the races. But other black leaders criticized him for tolerating racial segregation at a time of increasing anti-black violence and discrimination.

Washington did publicly speak out against the evils of segregation, lynching, and discrimination in voting. He also secretly participated in lawsuits involving voter registration tests, exclusion of blacks from juries, and unequal railroad facilities.

By the time Booker T. Washington died in 1915, segregation laws and racial discrimination were firmly established throughout the South and in many other parts of the United States. This persistent racism blocked the advancement of African Americans.

W. E. B. Du Bois

W. E. B. Du Bois was born in Massachusetts in 1868. He attended racially integrated elementary and high schools and went off to Fiske College in Tennessee at age 16 on a scholarship. Du Bois completed his formal education at Harvard with a Ph.D. in history.

Du Bois briefly taught at a college in Ohio before he became the director of a major study on the social conditions of blacks in Philadelphia. He concluded from his research that white discrimination was what kept

How did successful military campaigns lead to the creation of independent nations in south america?
djyliett [7]

The Spanish king ordered officials to look into the system of forced labor and eventually abolished it. This is how military campaigns were led to creation of independent nations in South America.

<u>Explanation</u>:

The people in Latin America distrusted and feared one another after dissatisfaction with Spanish rule. Sometimes they worked together against the Spanish. But once independence was achieved, the creoles, who had led the revolts, dominated the governments.

The process of independence of the South American countries has more to do with the American Independence and the defeat of the British, as well as the French revolution and the Napoleonic wars. The culture and outlook of the people was inspired from European conquerors and immigrants. The majorities of South Americans speak Portuguese or Spanish and follow Western traditions.

The widespread revolutionary ideals ensuing from these important changes in European political board made locals settlers and non-whites question their allegiance to metropolitan authority, as well as the elite, who were tired of trade restrictions.
