Reconstruction was a failure due to the opinion on race. Racism played a big part in the 1896 Plessey vs. Furguson case. Reconstruction began in 1865 and ended in 1877. Two goals were to rebuild the south and to reform society. Reconstruction should not be thought of as a bad idea. It was virtually impossible to just change ways in the south with out using some kind of force. "Black codes" did nothing but for the south but put them in further segregation. The black codes aloud a form of disguised

Reconstruction occurred from 1865 to 1877. It could be considered successful because it restored the United States as a whole after the Civil War. Even though it brought the states back together‚ it stilled failed in many ways. Reconstruction gave the Government a chance to end segregation and change society’s view of African Americans‚ but nobody took it. Reconstruction amplified racial discrimination. Some examples being “Black codes‚” sharecropping‚ and the Ku Klux Klan. The “Black Codes” were

Melting pointe determination #01 Introduction: Objective To learn how to obtain an accurate melting point using a MELTING POINT APPARATUS‚ then use them to draw eutectic curve and determine the eutectic point. Melting point of a solid is the temperature at which the solid and its liquid form are in equilibrium‚ i.e.‚ molecules move back and forth between the two states at the same rate‚ so both phases remain present. If the temperature of a solid is measured carefully as the solid is heated

Determination of an Equilibrium Constant Abstract: In this experiment‚ two reactions were run to determine the molar absorptivity and the equilibrium constant of FeSCN2+. The main principles used in this lab are equilibrium‚ LeChatlier’s Principle‚ Beer’s Law and Spectrocopy. The first reaction was run to completion using LeChatier’s Principle and the second reaction was run to equilibrium. A spectrophotometer was used to measure absorbances. Using a graph of absorbance versus concentration

Lab 7: Determination of Water Hardness Using a Titrator Name: Kyndal Petrie Lab Partners: None Date of Experiment: July 19‚ 2013 Location: My house Course Number: Che112 Abstract: This experiment was to determine the hardness of the local water supply. I determined that from the 1mg of EDTA used to turn the mixture blue‚ that the water from my tap is moderately soft. Experiment and Observation: In this experiment I developed a familiarity with the concept

Reconstruction was the time of rebuilding after the Civil War in the South when the radical Republicans wanted to grant equality to the freedmen. Even though there was success‚ reconstruction ultimately failed to grant equality. Eco Reconstruction failed to give the freedman economic stability‚ the sharecropping system made it impossible to gain economic stability‚ it explains that when a farmer promises land and seeds to a worker in exchange for half of the produced crop. In this cycle the worker

One of the most important questions in the late 1800s is how do you rebuild after the death of the one man who held the country together through a civil war‚ President Lincoln‚ and after the decimation of Southern infrastructure; much to the dismay of the Republican party‚ who controlled the politics at this time‚ the Reconstruction failed to accomplish its chief goal of promoting equality as the country fell back into its antebellum ways. In an effort to right the wrongs of the past‚ Republicans
