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

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

reaction where the concentration of all the reactants and all the products remain constant over time. Equilibrium as used in chemical systems means that all the chemical forces in a reaction are in balance and that all physical properties of the system (color‚ density and concentration) of all chemicals species involved remains constant. The equilibrium state can be characterized by quantitatively defining its equilibrium constant‚ Keq. In this experiment the Keq for the reaction between iron (lll) ions
