LE CHATELIER’S PRINCIPLE Castro‚ Lharize C. Experiment # 1 I. Introduction: In this experiment‚ using Le Chatelier’s principle‚ we will observe several responses of a system at equilibrium to various changes in external conditions. The experiment aims to investigate two equilibrium systems: (a) cobalt complexes and (b) chromate-dichromate equilibrium and explain observations in light of the Le Chatelier’s principle. II. Theory/Concepts: In 1884 the French chemist and engineer Henry-Louis

Living on Your Own. Living on your own doesn’t seem to be a big deal in the beginning. Despite all the disadvantages of living on your own the benefits of it are far greater. While living on your own you can develop important life skills such as time management and greater responsibility‚ which will lead to a more mature stage of life. When this stage of life is achieved you can decide what and how you want to live the rest of your life. When it comes to the point of living away from your parents

Applications of Le Châtelier’s Principle (September 11 - 15‚ 2014) **The purpose of this experiment was to visually observe the effects of how changing certain aspects of the reaction affected the observed equilibrium. PROCEDURE: Introductory activity Part A: Effect of Concentration: Two different temperature water baths were created‚ one at 65-70oC‚ the other ice‚ and set aside for Part B. 20 mL of potassium thiocyanate solution were poured into a petri dish. The initial color and all subsequent

antiquities should be returned to their country of origin is both controversial and crucial‚ because museums in Europe and America own many disputed items in its collections. The most glaring example is the British museum‚ where the refusal to return the Elgin Marble to Greece has brought the issue to international attention. In response to the problem‚ James Cuno in Who Owns Antiquity? argued that although antiquities should be protected from looting‚ they should not have to be kept in the counties in

In the poem‚ ‘An Absolutely Ordinary Rainbow’ by ‘Les Murray’ reflects upon a different type of society as feelings and emotions are kept secret. In the first stanza of the poem Murray uses imagery to paint a picture in the readers mind of a busy city coming to a halt‚ ‘Pitt Street is baked up for almost half a mile.’ At the end of the stanza Murray again uses imagery to make the readers see a man crying. People walk by him and see him crying but they do not stop him. The man in this poem is not

Lab 4: Le Chatelier’s Principle Name: Cammey Mahowald Lab Partners: None Date of Experiment: March 16‚ 2015 Course: CHE 112 Abstract: The purpose of this experiment is to understand the components of a reaction at chemical equilibrium and use Le Chatelier’s principle to predict the direction an equilibrium position will shift upon changes in the concentration‚ temperature‚ and pressure. It was determined that in the equilibrium of chromate and dichromate it is an exothermic reaction and in the

“Here I’ am Taking My Own Picture”- Analytical Its hard to imagine a time where photographs actually took time to produce. First of course to take the photograph‚ and then into the dark room where the film was transferred onto special paper to be put through developing chemicals. In the end you would hope for the best and that you looked good in the photo. It wasn’t all that long ago that this process existed. However‚ now we live in a technological world where anything is possible. You no

ENDING!” Seeing this‚ what would be a topic to ruminate about at that moment? Is the world really ending? Is this just propaganda like so many other things? I agree with the quote “The desk is a dangerous place from which to watch the world” by John Le Carre because it relates to what people think and how their outcome can change the situation. This in fact is the situation in most cases since it relates to so many exemplary actions. Relating it back to the example‚ one wouldn’t believe that the
