Chemistry 12 Santa Monica College Determination of Kc for a Complex Ion Formation Objectives • • Find the value of the equilibrium constant for formation of FeSCN2+ by using the visible light absorption of the complex ion. Confirm the stoichiometry of the reaction. Background In the study of chemical reactions‚ chemistry students first study reactions that go to completion. Inherent in these familiar problems—such as calculation of theoretical yield‚ limiting reactant‚ and percent yield—is

Delhi Sultanate‚ principal Muslim state in India before the advent of the Mughal Empire. It was founded in 1206 by Qutubuddin Aibak‚ a lieutenant of Muhammad of Ghaur‚ the Muslim conqueror of north India. It remained confined to the north under Qutubuddin Aibak’s Slave dynasty (so called because he was once a slave of Muhammad). Under the Khalji dynasty (1290-1320) its control was extended over most of the subcontinent. Alauddin‚ the second Khalji sultan‚ repelled an attempted invasion by the Mongols

Ötzi the ice man On September 1991‚ two hikers discovered a frozen body in Ötztal area near the border of Austria and Italy. Further examination of the body revelled that it was an old frozen mummy lived thousands years ago. The body was called Ötzi the iceman‚ after the Ötztal area where he was found. Various technologies and scientific methods were used by historians and archaeologists tried to work out the life and death of Ötzi. Some of these major methods are: Examining the photos from the

As I began to do research on IPO’s‚ I wanted to make sure that I had a clear understanding of what exactly an IPO was. Initial Public Offering can be defined as the first sale of stock by a formerly private company. An IPO (Initial Public Offering) can be used by either small or large companies to raise expansion capital and become publicly traded enterprises. Many companies that undertake an IPO also request the assistance of an Investment Banking firm acting in the capacity of an underwriter to

Producers are the plants and the tress in the ecosystem that provide the energy to the ecosystem. As for the desert the producers are cactus and grass. The consumers of the ecosystem are in three different kinds‚ they are herbivores‚ carnivores‚ and omnivores. Herbivores are the consumers

Usually the power of the present societies is tripartite. The power is divided into an executive‚ a legislative and a judicative part. As though is it also in the science fiction film Equilibrium written and directed by Kurt Wimmer. After World War III only one civilised stronghold is left‚ the city-state Libria. The city-state contains the same structure of state as we know it today from totalitarian states. However the power of state is tripartite and Preston is part of the executive apparatus

Introduction: Solubility equilibrium refers to the dissolution of a compound in water. Specifically‚ the degree to which a compound is soluble (Tro‚ 739). This can be measured using the expression Ksp = [Mb+]a[Xa-]b‚ in which Ksp represents the solubility product constant (Thorne‚ 90). This constant is important because it does not change at a given temperature‚ regardless of the solution a compound is in; a smaller constant would indicate lower overall solubility. It is important to note that

Restoring Balance LeChâtelier’s Principle and Equilibrium Introduction Chemical equilibrium is a true balancing act. What happens when the balance is disturbed? The purpose of this lab is to observe the effects of concentration and temperature on equilibrium and to visualize how balance can be restored based on LeChâtelier’s Principle. Background Not all chemical reactions proceed to completion‚ that is‚ to give 100% yield of products. In fact‚ most chemical reactions are reversible
