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

Equilibrium Essay How does Equilibrium fulfil the conventions of a dystopic text? In what way does it subvert them? 1000-1500 words. A dystopia is a futuristic and technologically advanced oppressive world with an overbearing totalitarian government who maintain strict authoritarian control over its population. Dystopia’s are often concealed as utopias since everybody appears to be equal and life appears to be fair‚ but in reality freedom is greatly restricted under a dystopia. Kurt Wimmer’s Equilibrium

Chemical Equilibrium ------------------------------------------------- ------------------------------------------------- RESULTS AND DISCUSSION A. Iron-Silver Equilibrium In studying equilibrium between iron and silver‚ 0.10 M FeSO4 and 0.10 M AgNO3 were used. The balanced equation for the reaction is: FeSO4 (aq) + 2 AgNO3 (aq) ↔ Fe(NO3)2 (aq) + Ag2SO4 (s) It has a net equation of: Fe2+(aq) + Ag+(aq) ↔ Fe3+(aq) + Ag(s) This part of the experiment

equilibria of the simultaneous game b. (5pnts) Now suppose the game is played sequentially. Find the subgame perfect equilibrium if player 1 goes first and if player 2 goes first. c. (5pnts) Discuss whether each of the players would want to go first or second. d. (5pnts) Write down a system of equations such that the solution to the system would give a completely mixed strategy equilibrium of this game (please clearly define all of your notation). Can this system of equations be solved? (Hint: think about

intervene in the market system to fix prices above or below equilibrium if they believe that it is in the public interest to do so. Governments may intervene in the provision‚ regulation‚ maintenance and management of public goods to maximise the benefits to the community from their use‚ and to prevent over exploitation or congestion of the resource. A price ceiling is where a maximum price for a good or service is established below market equilibrium. It can make products more affordable for consumers

when a price ceiling is established on a product in which the price is thought to be too high; however a more efficient means of solving this problem would be to increase production. An ineffective price ceiling is one that is set above the market equilibrium price. The product is already selling for much lower than the price ceiling‚ so unless the price greatly increases‚ the price ceiling serves no vital purpose. Price floors are a government

Chemistry 12 Unit 2 Notes - Equilibrium Chemistry 12 Tutorial 5 – The Equilibrium Constant (Keq) What is Keq ? The "K" in Keq stands for "Constant". The "eq" means that the reaction is at equilibrium. Very roughly‚ Keq tells you the ratio of Products/Reactants for a given reaction at equilibrium at a certain temperature. [Products] [Reactants] K eq = It’s not quite this simple when we deal with real substances. Let’s take an example. It has been found for the reaction: 2HI(g )

by a person. Group development research has proposed various models to explain how new groups form‚ work together‚ and disband. These models fall into two categories: Five stages model‚ often exemplified by Tuckman‚ (1965); and the punctuated equilibrium model of Gersick (1988). In this paper it will be analyzed which model is more applicable or otherwise there are some conditions‚ that requires a development of an integrated model of group development that can combine these two types of models
