Introduction In a reaction where a slightly soluble ionic solid is dissolved in water‚ it ionizes into its respective ions. It signifies that equilibrium between the undissolved and dissolved ions in a saturated solution has been established when a precipitate forms. The solubility of the solid ionic compound Calcium Hydroxide was observed in this experiment. In the equilibrium reaction of Ca(OH)2 Ca(OH)2 (s)⇌Ca(aq)2++ OH(aq)- [1] ‚ the solubility product constant‚ Ksp‚ is represented by Ksp=Ca2+OH-

followed by the reduction in the production of mangoes. Therefore‚ the supply of Alphonso mangoes would be decreased as a result of it. It is important to emphasis on the concept of market equilibrium. Market equilibrium is when the supply of an item is equal to its demand. Once the equilibrium price and equilibrium quantity achieved‚ there will be no excess

incentives and motivators which can encourage unethical decisions that can mar a firm’s reputation. 3) Define the Nash equilibrium. Why is this concept applicable to many oligopoly industries? Nash equilibrium is a set of mixed strategies for limited and non-cooperative match between two or more firms in which no firm can improve its payoff by switching strategy. Nash equilibrium maintains focus on rivalries with mutual gain. Oligopolistic firms chooses prices and inputs to maximize profits‚ however

off a bit more towards a slope of zero (0.084 A/min). This can be explained using Le Chatelier’s principle‚ which states that if a dynamic equilibrium is disturbed by changing the conditions‚ the position of equilibrium shifts to counteract the change to reestablish an equilibrium. The initial conditions prior to any change can be viewed as a state of equilibrium because no reaction was occurring and therefore no products were being formed. However‚ once peroxidase was added to hydrogen peroxide‚ oxygen

Introduction The equilibrium constant for the solubility equilibrium between an ionic solid and its ions is called solubility constant [1] ‚ Ksp of the solute. For example‚ the solubility product is defined by MxAy(s) ⇋xM(aq)y++ yA(aq)x- (1) Where M is the metal cation‚ A is the anion‚ x and y are the corresponding charges of the ions. The equilibrium expression is Ksp=[MY+]x[AX-]Y (2) In the example‚ MxAy(s) does not appear in the equilibrium constant expression
