Abstract Chemical equilibrium occurs when a reversible reaction is happening forward and backward‚ at the same time by the same amount‚ is equal. Two procedures were made. First is the Effect of Concentration on Equilibrium. The solution became orange when it was diluted with ammonium hydroxide and the solution became yellow when water was added to the solution. In the second‚ Effect of Temperature on Equilibrium‚ the solution turned into a light brown gas when it was placed in the refrigerator

The Life Cycle of Resistance to Change What is change? After doing some research I came discovered that there are many different definitions of the word change. Webster’s dictionary says that change means to give a different course‚ position‚ or direction to (Merrriam-Webster‚ 2010). Whenever you add the word change to organizational it takes on a somewhat different meaning. Organizational change is the term used to describe the transformation process that a company goes through in response to

Everyone has there own way of learning ‚ not everyone is the same. Observation is to become familiar with the insiders to refine and subsequent observation and data collection. It has become aparent to me in the past few months that most people are not really thinkers‚ but are more observers .One who doesnt understand their learning style is never really learning. Observing and learning is the concept to everything we do in this life. Actively recording thoughts and information learned is the most

O“Observation” By Henry David Thoreau “Observation‚” by Henry David Thoreau‚ is a passage that presents the idea that there is no such thing as pure objective observation‚ only subjective observation. Written during the Age of Enlightment‚ philosophes Thoreau stated that observations do not need to be true and accomplish an overall purpose because observations come from the individual and what he or she believes in. Thoreau was able to illustrate this idea in this text through examples like “though

Experiment 3: Chemical Equilibrium Purpose The purpose of this experiment was to determine the equilibrium constant for the formation of FeSCN2+. Introduction Chemical equilibrium is the point in a reversible reaction where the concentration of the reactants and that of the products remains constant. This point of equilibrium is referred to as the Kc value‚ which can be obtained using the formula: Kc = [product] [reactant] In this experiment‚ we used a spectrophometer to
