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‚

An Absolutely Ordinary Rainbow-Les Murray. In Les Murray’s ’An Absolutely Ordinary Rainbow’‚ there is a clear unconventional portrayal of the hero‚ and he shows many heroic concepts as a result of the dramatic techniques used to convey the notion of the weeping man not being society’s ’conventional perception’ of a hero. The poems persona is simply an un-named ’observer’ who tells the story‚ in a third person present tense narrative form ("they") which assists in portraying the notion that a weeping

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.

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 Nozze di Figaro or The Marriage of Figaro is known as an opera buffa or comic opera that is broken into four acts. Wolfgang Omodeus Mozart composed this piece in 1786‚ along side an Italian libretto written by Lorenzo de Ponte. It premiered May 1‚ 1786 at the Burg Theater in Vienna. It was Mozart who originally selected Beaumarchais’s play and brought it to Da Ponte‚ who was able to turn it into a libretto in just six weeks‚ rewriting it in poetic Italian and removing all of the original’s political
