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

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

Some say that the idea of love in modern terms differs conceptually from that of earlier periods. That argument is demonstrably false. Although love has been characterized in many different ways throughout the ages‚ the fundamental idea remains constant. No matter the eccentric personalities love is entitled to‚ love is what it is. From a literary point of view‚ whether one reads the tender longing of Sappho‚ the unattainable desire of Petrarch‚ or the whimsical prose of Dickenson‚ the message

1. Two ships P and Q are moving along straight lines with constant velocities. Initially P is at a point O and the position vector of Q relative to O is (6i + 12j) km‚ where i and j are unit vectors directed due east and due north respectively. The ship P is moving with velocity 10j km h–1 and Q is moving with velocity (−8i + 6j) km h−1. At time t hours the position vectors of P and Q relative to O are p km and q km respectively.

The quote above illustrates how Foucault claimed that being aware of constant surveillance created a sense of self-governance. Even tough there was not any set laws due to the fear Big Brother installed‚ the citizens of Oceania lived very precautious‚ uncertain of when or how they would break the law. Winston was constantly blocking out any thoughts not regarding big brother. The constant surveillance consequently created a sense of always policing themselves. Winston made sure he maintained a good

In his notable novel‚ The Stone Face‚ author William Gardener Smith reveals the complications that arise when one’s ideals are questioned and put into focus. This complexity is demonstrated through the character of Simeon Brown as he tries to negotiate the condition of his racial ideal. However‚ the complex nature of his conviction poses a challenge that he struggles to overcome. As he makes every effort to understand the principle of race in his life‚ Simeon essentially grows to recognize the true
