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

Europe in 1800s. In 1806‚ John Stuart Mill was born in Pentonville‚ then a suburb of London. He was a son of James Mill‚ who became leading figure in the group of philosophical radicals and Jeremy Bentham’s discipline and friend. Mill co-wrote “On liberty” with his wife‚ Helen Taylor and published in 1958. On the other hand‚ Jeremy Bentham who was philosopher and jurist was born in 1748 in London. He brought utilitarianism about 19 century. His maximizing happiness on great number of people might inspire

Report: Calculating the Spring Constant and Verifying that Energy is Conserved Within a System Abstract: An experiment was conducted to determine the spring constant of a spring in the cart by measuring the force required to compress a spring as well as the distance the spring compressed relative to the equilibrium position. A cart was placed onto a slanted track and speed and force censors were used to record appropriate data. The spring constant was determined by substituting

molecules (or atoms) in a gas are separated by large distances and are in constant‚ random motion. When dealing with gases‚ the Ideal Gas Law equation is the most famous equation used to relate all the factors in dealing and solving the problem. The four factors or variables for gas are: pressure (P)‚ volume (V)‚ number of mole of gas (n)‚ and temperature (T)‚ and the constant in the equation is R‚ known as the gas constant. The Ideal Gas law equation which is pV=nRT is obtained by combining the

In hopes of acquiring deserved freedom‚ slaves had the right to kill their masters. But while justified‚ violence was futile‚ leading to execution rather than freedom. Constant victims of injustice‚ slaves were dehumanized and dominated by their master. They were unable to conduct their own actions without the permission‚ incapable of traveling without slave passes‚ and often separated from their family. Slaves were treated as livestock and traded at their master’s will. Masters regarded their slaves

Lab: Electrostatic Coulomb Constant Rylee Rose Date: 1/28/13 Abstract: This experiment was done to study electrostatic and Coulomb’s law. Objective: The objective was to demonstrate the veracity of Coulomb’s Law. This was done by observing different equilibrium conditions of two pith balls that were equally charged. They were then constructed into a pendulum using strings. Calculations were done to determine the charge on pith balls‚ calculate the mass of the pith balls and to calculate

Bifocals are eyeglasses with an upper and lower half‚ the upper for distance‚ and the lower for reading. Bifocals are commonly prescribed to people with presbyopia‚ a condition that Franklin suffered. Franklin wrote‚ in August 1784 to his friend George Whatley‚ that he was "happy in the invention of double spectacles‚ which serving
