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

Generally‚ honesty is the best policy in any situation. Some people are very reliable and they hate those who tell lies for any reason. Other people accept “white lies” when situation arises‚ even if they usually do not like lying. I strongly agree that being honest is the most important consideration in a relationship. During our childhood‚ our parents teach us one of the greatest human values: always telling the truth. Based on this‚ parents can help us resolve life problems‚ and we build a

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

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

Quite often a guilty subject will invoke such expressions as‚ “I swear to God I’m telling the truth‚” “I hope my mother drops dead if I’m lying‚” “I’ll swear on a stack of Bibles‚” etc. Although expressions of this type cannot be considered as symptoms of deception‚ they frequently are used by guilty subjects in an effort to lend forcefulness or conviction to their assertions of innocence.

Throughout the entire play of Shakespeare’s “Othello”‚ the character Iago manipulates many of the other characters by appearing a certain way then hiding the truth of what he really thinks about the characters. The characters‚ such as Othello‚ believe that Iago‚ his (ensign???) is very honest and will never tell a lie‚ they even refer to him as “honest Iago” (add the act and the scene to this) because they have great faith in his character. Little does shakespeare’s characters know‚ but Iago has

What is honesty? To everyone honesty is different to some it is speaking nothing but the truth and to others honesty is telling part of the truth and possibly keeping other parts out of the equation. People can view themselves as honest meanwhile other people may call that very person a liar. We were taught that in first person stories there is never really truth you have opinions no matter what first person story your read the character will always put their opinion in or even possible even make
