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

Title: Study of Solubility Equilibrium Abstract The effect of temperature on the solubility product constant‚ Ksp‚ of potassium hydrogen tartrate in water was investigated in the temperature range of 285K to 318K at normal atmospheric pressure. It was found that the solubility of potassium hydrogen tartrate decreases with a decrease in temperature and consequently a smaller volume of sodium hydroxide is needed to neutralize it. The molar solubility of potassium hydrogen tartrate was calculated

Equilibrium Kurt Wimmer’s film Equilibrium (2002) is set in color. It tells a story about how suppressing emotions eliminates war‚ and any books‚ art‚ or music is forbidden. Those who are caught being a sense offender has committed a crime punishable by death. The film demonstrates the true source of man’s inhumanity to man. The internal struggle within the characters throughout the film such as with the main character Cleric John Preston (Christian Bale)‚ contributes to the theme of the Truth of

Equilibrium Paper By: Brandon Walker ECO/561 July 14‚ 2014 Instructor: Mark Erenburg This paper was written to describe a real world experience in a free market were change occurred in supply or demand as a result of world events that led to the need for a move between two equilibrium states. I will also explain the process of how that movement occurred using behavior of consumers and suppliers while using graphs as indicated. Real Word Experience According to a United

Nash Equilibrium and Dominant Strategies Nash Equilibrium is a term used in game theory to describe an equilibrium where each player’s strategy is optimal given the strategies of all other players. A Nash Equilibrium exists when there is no unilateral profitable deviation from any of the players involved. In other words‚ no player in the game would take a different action as long as every other player remains the same. Nash Equilibria are self-enforcing; when players are at a Nash Equilibrium they
