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 equilibrium of ferrocyanide and ferric ferrocyanide that it is an equilibrium shift to the left after adding NaOH.

are set teams that work on many projects as a whole. They follow the Five stage Model with the exception of pregroup‚ Forming‚ and storming. This group has been together for a while thus the first few are not needed‚ neither is the Punctuated equilibrium model The illuminator team has many different people I terms of characteristics; It doesn’t look they have one person to one type of task. This goes against the “roles” (pg 171) The team has a reward system that allows for positive feedback

Penny-Ante Equilibrium Introduction What is equilibrium? What happens to the amount of reactants and products when equilibrium is reached? What if more reactants or products are added to a system already at equilibrium? In this activity‚ pennies will be used as reactants and products in a reversible reaction to answer these questions and learn more about the fundamental nature of equilibrium. Concepts • Reversible reactions • Equilibrium • Equilibrium constant • LeChatelier’s principle Materials

The Determination of Keq for FeSCN2+ Joy Muthami February 12 2014 Introduction: The purpose of this lab was to calculate the equilibrium constant for the reaction of iron (III) ions with thiocyanate ions. The materials were first acquired then with the groups in the class each team was given a test solution to create and acquire information from then all the information was put together in order to save time. Specifically the group created test solutions #8‚ #9‚ and #10. Once the solutions were

Question: Was $500 the equilibrium market price last year? According to the given information‚ I think there are two possible situations: Situation1. $500 was the equilibrium price. Since the seats in the coliseum cannot be changed‚ so that the supply of the tickets is perfectly inelastic. Thus the supply curve shall be vertical. Here is the demand curve and supply curve of these two years. Last year‚ $500 was the equilibrium price‚ the market was at the equilibrium point. Besides‚ 36‚000

Strayer University ECO 550 Week 1 Homework Chapter 1 2. A principal-agent relationships involves the owners (principals) delegating decision-making authority to managers (agents). A conflict occurs when the agents pursue acceptable levels of shareholder wealth and profit rather than a maximization of profit. They are pursuing their own self-interests. One way that the agents act in their own self-interests would be by focusing on long-term job security. This could cause the agents to limit

disequilibrium of greed portrayed in Kino’s imaginary story indicated that equilibrium is not only necessary at the lowers of social status‚ but also required in the economy and global market today. Jamie Woodwell‚ in her article about mortgage banking‚ titled‚ A Detour to Dis-Equilibrium‚ speaks about the global market saying‚ “When a shock hits a market— a dramatic shift in supply or demand— the market moves to dis-equilibrium. When that happens buyers and sellers cannot come to terms‚ the market slows
