esterification reaction that was carried out in this lab is shown in figure 1. It worth mentioning that the by-product of such reaction is water. In organic chemistry‚ the reaction in which water molecule is released is known as condensation reaction (Hornback‚ 2006).

Introduction Chemical kinetics is the study of reaction rates. A reaction rate is the speed of the change in either reactants or products over a period of time. General kinetic rate equation is: Where [A] and [B] are the concentration of the species in the reaction. The variable k is the rate constant‚ which is a function of time and catalyst presence. The variables m and n are the order of reaction for their respective species concentration. The higher the value of the reaction order the

In this lab we are going to be observing the decomposition of piglets over a month’s time. There are theory questions that have been given to us before and after the lab. We look back at our original theory to see where we went wrong‚ and then correct it. The lab was disgusting‚ surprising‚ and very interesting. The first questioned to be answered is which piglet decomposes faster‚ a piglet that is in its natural state‚ that is burnt‚ that is buried‚ and that is buried in a wooden box? With

African Diaspora and the World After reading the short story “Diaspora” by Joanne Hyppolite‚ I got a vivid understanding of how diaspora can have an effect on one’s identity. Over the past month we have studied many theories and concepts concerning race‚ gender‚ and politics. There are three theories that capture the essence of Joanne Hyppolite’s worldview as a Haitian growing up in America: intersectionality‚ identity‚ and diaspora. Individuals oftentimes experience the theory of Intersectionality

supremacists’ desires and claimed that white genes were inherently superior to other races‚ and with this base formed the first eugenics society. The American Eugenics Movement attempted to unethically obliterate the rising tide of lower classes by immorally mandating organized sterilization and race based experimentation. The first step in its movement to uphold the social status of white supremacists was to create a scientific base on which to build the belief that eugenics was ultimately a good cause. Eugenicists

The Civil Right Movement was successful because it ended segregation. First‚ Ruby was born in Tylertown‚Mississippi on September 8th 1954. “Ruby Bridges” was the first African American girl being escorted by United States to attend an all American white school. Tulane University Presented Bridges with honorary degree in 2012. Ruby was born to sharecroppers Aborn and Lucille Bridges.Ruby parents decided to move the family to New Orleans in 1958 when Ruby was 4 years old. Next‚ “Martin Luther

The Progressive Era‚ which lasted from 1900 to 1918‚ was a time in which the American government and its people aimed to improve their economic status and to correct injustices of their country. Here are the ten leading reform movements: 1. Civil Rights After the Civil War‚ some would have expected that racism would have stopped but unfortunately‚ that didn’t happened. Racism still existed in the American society in the stated era therefore civil rights organizations‚ most made for African-Americans

Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise

Geometrical Optics: Snell’s Law PHY101 Lab 12 Date: July 23rd‚ 2012 Objective: The purpose of this laboratory activity is to develop a set of experimental procedures that answer questions regarding Snell’s Law and the index of refraction. Ultimately‚ the experimental procedures you develop will allow the index of refraction to be found for water and cooking oil. 1. Explain how to experimentally determine the index of refraction of two substances. 2. Develop a set of experimental

From the late 1960s‚ to the early 1980s‚ the Black Power Movement (BPM)‚ triggered by the shortcomings of the Civil Rights Movement (CRM) and influenced heavily by Malcolm X‚ used a variety of techniques‚ including an increasingly militant approach‚ to bring about the change African-Americans demanded‚ with some success and a legacy that still endures today. The Black Power Movement heavily owed its existence to the Civil Rights Movement‚ which failed to address certain key areas. While the CRM
