Heat of Formation of Magnesium Oxide Objetive: To determine the heat formation of MgO (Magnesium Oxide) using Hess’s Law‚ which states the heat within a chemical reaction is independent of the pathway between the initial and final states. Introduction: Chemical reactions require heat energy to complete‚ called an endothermic reaction‚ or produce heat energy‚ and thus called an exothermic reaction. The heat energy produced by such reactions can be measured using a calorimeter‚ a piece

specific structural formula which is called " Disney Formula of Success" ( Eisner 114 ). As it is understood by its name‚ the economic success of the company has guaranteed for years with the help of this formula. All of the animated features of Disney Company have this structural production pattern ( Disney Formula of Success) although they differ in so many ways. But one of these animated feature which is called Pocahontas’ differs from the others in the process of using the formula. In this paper

acceleration due to gravity at the Earth’s surface (g) g’ = (re2 / r2) g Acceleration due to gravity inside the Earth Here let r represent the radius of the point inside the earth. The formula for finding out the acceleration due to gravity at this point becomes: g’ = ( r / re )g In both the above formulas‚ as expected‚ g’ becomes equal to g when r = re.

CHEM 1105 Experiment 4: Determination of a Chemical Formula Introduction When atoms of one element combine with those of another‚ the combining ratio is typically an integer or a simple fraction. The simplest formula of a compound expresses that atom ratio. When two or more elements are present in a compound‚ the formula still indicates the atom ratio. To find the formula of a compound we need to find the mass of each of the elements in a weighed sample of that compound. For example‚

● Cobalt(II) Chloride Hexahydrate CoCl2.6H2O‚ was weighed in a weighing boat. The Cobalt(II) Chloride Hexahydrate was transferred into a 100mL volumetric flask dissolved in water. ● 25 mL of the dissolved was measured‚ using a graduated cylinder and few of the dissolved Cobalt (II) Chloride Hexahydrate‚ was poured into test tube. The test tube was labeled with a tape‚ to signify 25 mL and the spectrophotometer was used to record the U-V visible ABS (absorbance spectrum) with the wavelength of 515

ANTACIDS- Classification and Mechanism of Action INTRODUCTION Antacids are defined as a substance‚ generally a base‚ which counteracts stomach acidity. The name antacid means anti-acid (against acid). Antacids are the primary treatment for ailments such as gastric reflux‚ gastritis‚ upset stomach and heartburn. Hydrochloric acid is secreted by the stomach to kill harmful organisms‚ aid digestion and activate digestive enzymes. Excess secretion of acid into stomach or impaired resistance by

Preparation of t-Butyl-Chloride March 8 & 15‚ 2012 Theory: Alkyl halides can be synthesized when alcohols react with hydrogen halides. An alkyl halide is a halogen-substituted alkane‚ and a hydrogen halide is a compound consisting of a hydrogen bonded to a halogen (H-X). Alkyl halides are classified as primary‚ secondary‚ or tertiary depending on the number of alkyl substituents directly attached to the carbon bearing the halogen atom. The purpose of this laboratory experiment was to prepare
