Experiment 11 Date: 28-3-2011 Title: Interpretation of reaction by the Le Chatelier’s principle Objective: To determine the factors that affecting the equilibrium position Introduction: Le Chatelier’s principle states that if a system in equilibrium is subjected to a change‚ the equilibrium position of the system will shift in a direction to minimize the effect of the change. Iron(III) ions and thiocyanate ions (NCS-) react in solution to produce thiocyanatoiron(III) (FeNCS2+)‚ a

Experiment No. 2: Dynamic Equilibrium and Le Chatelier’s Principle December 1‚ 2011 Final Formal Results Le Chatelier’s Principle states that “when a stress is applied to a chemical system at equilibrium‚ the equilibrium shifts in a direction that reduces the effect of stress” (Gross‚ Abenojar‚ and Tan 23). Moreover‚ it helps us “predict the direction of the shift of the equilibrium” (Silberberg 745). Silberberg also stated that there are three kinds of disturbances - concentration‚

Murray Davis’ Smut‚ Erotic Reality/Obscene Ideology In the book Smut‚ Erotic Reality/ Obscene Ideology ‚ by Murray Davis (1983)‚ the author expresses the idea that the best source for studying human sexuality objectively is "soft core"‚ rather than "hard core" pornography. (Davis p. xix). The purpose of this paper is to critique Davis’s claim and to study what understanding of human sexuality someone might have if they used some other resource that is available today‚ in this case the Internet

Chemical Equilibrium: Le Châtelier’s Principle Abstract This experiment entitled "Chemical Equilibrium" aims to help students to investigate the effects of concentration and temperature upon the position of equilibrium in a cobalt chloride solution‚ Co(H2O)62+. In this experiment‚ cobalt crystal is dissolved with distilled water and ethanol which the initial colour is purple-pinkish and a few drops of concentration of HCl is added to the test tube‚ the final colour is in deep blue colour.

The Victorian era’s patriarchal ideals rooted on fear of female empowerment influenced Joseph Sheridan Le Fanu’s lesbian vampire novella‚ Carmilla. The social ambience created by patriarchy at the time limited women to be objects of desire to be owned and controlled by men. In hopes of defying this social construct Le Fanu creates Carmilla‚ a vampire who feeds on and loves other women. Her independence from and disregard for the patriarchy challenges male kinship. The novella Carmilla is an attempt

Le Morte d’Arthur: An Allegory Le Morte d’Arthur‚ written by Sir Thomas Malory‚ are tales of the legendary King Arthur. Through symbols and themes‚ it is shown that Le Morte d’Arthur is an allegory of the corruption of Arthur’s court. These symbols are those of faith‚ temptation of fate‚ and the selfishness of the knights and the mortality of the people. Faith and fate was on Arthur’s side. Sir Gawain appeared in Arthur’s dream. “And for the great grace and goodness that Almighty Jesu hath unto

I have not listened to a story that made me feel happy and sad at the same time except for Tan Le’s story. Le spoke about her family story of immigration. A four years old girl‚ a mother and a sister were trying to escape to Australia to find a better life. Her story showed us how life could be tough and bitter. She and her mother and sister struggled a lot until they survived. Le has used a descriptive language in order to make her story effective and hook her audience attention. To illustrate‚

LE CHATELIER’S PRINCIPLE EXPERIMENT 2 AMANDA BUCHANAN – SEPTEMEBER 15‚ 2015 CHEMISTRY 1212- SECTION 50 OBJECTIVES: The objectives of this experiment are to be able to define equilibrium‚ equilibrium position‚ equilibrium constant‚ reaction quotient and Le Chatelier’s Principle. Another objective is to explain how changes in temperature‚ pressure and concentration affect the equilibrium position of a reaction. Also‚ perform chemical equilibrium reactions and manipulate equilibrium positions
