Chemical Bonding Lab Chemical compounds are combinations of atoms held together by chemical bonds. These chemical bonds are of two basic types—ionic and covalent. Ionic bonds result when one or more electrons from one atom or group of atoms is transferred to another atom. Positive and negative ions are created through the transfer. In covalent compounds no electrons are transferred; instead electrons are shared by the bonded atoms. The physical properties of a substance‚ such as melting point

Chemical Bonding Chemical compounds are formed by the joining of two or more atoms. A stable compound occurs when the total energy of the combination has lower energy than the separated atoms. The bound state implies a net attractive force between the atoms ... a chemical bond. The two extreme cases of chemical bonds are: Covalent bond: bond in which one or more pairs of electrons are shared by two atoms. Ionic bond: bond in which one or more electrons from one atom are removed and attached to

Gulf Oil Corporation in 1984. This merger was the largest merger till that time in the history of the United States and it doubled the oil and gas reserves of the company. Chevron merged with Texaco in 2001 & formed a new company named ChevronTexaco. Texaco was one of the branches of Chevron family. It was formed in 1901 in Beaumont‚ Texas. To convey a unified presence in the world‚ it was again renamed to Chevron in 2005. Chevron strengthened its position by acquiring Unocal Corporation in 2005.

Case Study 3: Estimating the Cost of Capital 1. Currently Teletech Corporation (TC) uses a single hurdle rate for both their Telecommunications Services (TS) and Products and Services (P&S) divisions. This hurdle rate obtained by an estimate of TC Weighted Average Cost of Capital (WACC)‚ which is calculated at 9.3%. When analyzing critically at this point‚ TS is underperforming with a return on capital (ROC) of 9.1%‚ whereas‚ P&S segment is well over the required rate of return as it is gaining

Multinational corporations have existed since the beginning of overseas trade. They have remained a part of the business scene throughout history‚ entering their modern form in the 17th and 18th centuries with the creation of large‚ European-based monopolistic concerns such as the British East India Company during the age of colonization. Multinational concerns were viewed at that time as agents of civilization and played a pivotal role in the commercial and industrial development of Asia‚ South

Experiment 3: Chemical Equilibrium Purpose The purpose of this experiment was to determine the equilibrium constant for the formation of FeSCN2+. Introduction Chemical equilibrium is the point in a reversible reaction where the concentration of the reactants and that of the products remains constant. This point of equilibrium is referred to as the Kc value‚ which can be obtained using the formula: Kc = [product] [reactant] In this experiment‚ we used a spectrophometer to
