Prompt: Although the development of the Trans-Mississippi West is popularly associated with hardy individualism‚ it was in fact largely dependent on the federal government. Assess the validity of this statement with specific reference to western economic activities in the 19th century. In the late 1800s and early 1900s‚ the idea of the far west captivated many. The chance to begin life anew attracted thousands of individuals and families alike to move out west and escape their current life‚ which

domestic consumption stood 18.5 liters per capita. By 1996‚ more than 1‚000 wineries were establish in Australia. The largest accounted for 84% of the grape crush and 4 controlled over 75% of domestic branded sales. The number 2 company was BRL Hardy Ltd. During the 1980s and 1990s changes in the global wine industry had a major impact on these emerging Australian companies. Large scale wine suppliers from New Worlds countries such as US‚ South America ‚ South Africa and Australia were exploiting

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.

Unit 11: Kinetics and Equilibrium Activated complex: an intermediate state that is formed during the conversion of reactants into products‚ the structure that results at the maximum energy point along the reaction path. Activation energy: a chemical reaction is the difference between the energy of the activated complex and the energy of the reactants. Catalyst: substance that increases the rate of a chemical reaction by reducing the activation energy‚ but which is left unchanged by the reaction

CONDITION OF EQUILIBRIUM IBAÑEZ‚ Jonen Lery L. OBJECTIVE A torque is an influence‚ which tends to change the rotational motion of an object. One way to quantify a torque is force applied times the lever arm. In this experiment we consider the systems in equilibrium and its applications and how the forces acting on the system affect torque. To serve as a guide there are objectives set in performing this experiment. First objective is by the second condition applied to the systems of equilibrium and the

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 through concentration and temperature and perform calculations to determine the equilibrium constant (K) and the reaction quotient (Q) of
