Introduction: Chemical equilibrium is when the concentrations of the reactants and products have reached a state where reactions occurring in one direction are at the same rate of reactions occurring in the opposite direction. This process‚ called dynamic equilibrium‚ is the main subject of Le Chatelier’s Principle. Le Chatelier pointed out that if a system at equilibrium is subjected to a stress that momentarily causes the system to be not in equilibrium‚ a spontaneous change will occur to

Applied Corporate Finance Case: American Chemical Corporation The primary issue we are exploring here is the planned sale of the Collinsville Plant by American Chemical Corporation to Dixon at a negotiated price of $ 12 Million (as of end of year ‘79) Q1: Estimate the appropriate cost of capital for the investment To calculate the appropriate cost of capital we assessed Dixon’s purchase investment structure. The steps were as follows: 1. We first calculated the cost of debt of the investment using

Diamond initiates this chapter using Singapore as a model state for ‘Asian Exceptionalism’ as it appears to be the best example of a successful non-democracy. Singapore has little corruption‚ is efficiently run‚ caters to the welfare of its citizens and has a highly educated population. Under this ‘façade’ is a pseudodemocracy‚ with Lee Kuan Yew running the state autocratically‚ portraying Singapore with prized image the government attempts to maintains on an international level. However‚ the Singaporean

solution at 25° C. (i) Write the balanced chemical equation for the dissociation of Cu(OH)2(s) in aqueous solution. Cu(OH)2 Cu 2+ + 2 OH – (ii) Calculate the solubility (in mol/L) of Cu(OH)2 at 25 °C. (1.72 x10–6 g/0.100 L)(1 mol/97.5 g) = 1.76 x10–7 mol/L (iii) Calculate the value of the solubility-product constant‚ Ksp‚ for Cu(OH)2 at 25 °C. Ksp = [Cu 2+][OH –]2 = [1.76 x10–7][3.53 x10–7]2 = 2.20 x10–20 (b) The value of the solubility-product constant

Observation of Chemical Change Course: General College Chemistry Purpose This experiment examines the reactions of common chemical s contained in consumer products. The purpose is to observe the macroscopic changes that these chemicals undergo. The goals of the experiment observe properties of chemical reactions and to associate chemical properties with household products. Procedure We do not have the ability to see with a naked eye individual atoms and molecules reacting during chemical changes

Experiment 1: Observations of Chemical Changes Abstract: In the lab 1 experiment‚ the objective was to observed properties of various chemical reactions between twelve different basic compounds. Each reaction revealed chemical properties consisting of color change‚ CO2 gas formation‚ and/or precipitate formation. Certain reactions made it possible to distinguish between an acid and a base. Through the results of this experiment‚ chemical properties observed in the reactions could be used to associate

take over an airplane? Plenty of individuals would find it difficult unless they’ve got it all planned out perfectly. But in this case‚ a male that goes by the alias‚ Dan Cooper‚ or more widely known as D.B. Cooper‚ is famous for taking over a plane‚ asking for ransom money‚ and escaping. His fate remains unknown and is highly theorized about. The only plane hijacking case that remains unsolved is in fact‚ Cooper’s. The theories about the whereabouts of D.B. Cooper have been centered around the possibility
