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

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

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

Javert became suspicious of Monsieur Madeline when he lifts a cart of a man‚ and is justified in his suspicions. Javert said‚ "Monsieur Mayor six weeks ago after that scene about that girl‚ i was enraged and denounced you" The remarkable feat of strength that Madeline preformed caught Javert’s attention. Javert associated the strength with that of a convict and became suspicious. "I believed it‚ for a long while i had had suspicions." Javert’s suspicions are justified because it was indeed Madeline

COMUNIUTY SERVICE 4D Frederic Sadoun Community service is what makes the society much more joyful to live in. Some think community service is painful and they are only doing it because they are forced to and the need it to pass their high school‚ well I have a different opinion and I would like to share it. Community service can be really joyful because what goes around comes around meaning: the fact that I help someone I will get it back doesn’t matter if it’s in a day two
