Investigating Chemical Equilibrium Date: 30th April 2013 Due Date: 15th May 2013 Prepared For: M. Seraji Prepared by: Andrea Odunze Abstract Many reactions proceed to a state of equilibrium. A chemical reaction at equilibrium‚ where the rates of the forward reaction and reverse reaction are equal‚ looks like this: A + B AB There are three factors‚ according to Le Chatelier’s principle‚ that affect the equilibrium position and equilibrium constant. These are the concentrations of products

Discussion The reaction through which 4-mrthaoxyacetophenone is converted to 4-methoxybenzoic acid is a haloform reaction. This reaction involves two distinct stages that occur in the same environment. The first stage occurs through the based-catalyzed halogenation of the ketone that forms a trihalo ketone. First‚ the bleach is transformed into chlorine and hydroxide ions through the following reaction: Then‚ the hydroxyl is able to attack the rather acidic (pKa ~ 20) α-hydrogen of the ketone

CHARRY DEZZA L. SABANAL BSHRM 4-B REACTION PAPER OF JOSE RIZAL LIFE One note‚ this movie is not for the faint of heart. There are graphic depictions of violence and even torture. The opening few scenes depict some episodes from Rizal’s novels. In one a Catholic priest rapes a Filipina. I guess I now know where the Mestizo mixed blood class came from in the Philippines. In the other scene a Catholic priest beats a child for alleged stealing. Strong stuff and it made me wonder how the

Observing and deciphering Chemical Changes Purpose The purpose of this experiment is to observe reactions of chemicals that can be found in consumer products. Through observation‚ students should be able to interpret the chemical reactions and determine some characteristics‚ such as pH and solubility. Method 1. Pipets containing chemicals will be opened using scissors to snip the end and each pipet will be placed in a well of a 24-well plate. The scissors must be washed between each pipet. 2

from the smoke‚ containing Magnesium Oxide‚ the crucible had to remain covered. Some magnesium oxide escaped‚ when the crucible was not covered. The crucible had to be slightly ajar when heating up the magnesium‚ so that oxygen could get to the reaction. Without oxygen‚ a fire cannot exist. The shininess of the metal Mg turned to a dull appearance as it changed to MgO. As the magnesium reacted to the oxygen‚ it also reacted with the nitrogen in the air to form magnesium nitride‚ Mg3N2. To expel

Industrial Chemical Processes Essay Tan Hung Kai Grade 11 In our present world‚ there are thousands of chemical processes that are being used to produce products that benefits our daily lives. Industrial Chemical processes are used for “transforming raw materials into useful commercial products for society”. (Dr. Philip Britz-Mckibbin Industrial Chemistry: CHEM 2013) Examples of industrial chemical processes include distillation‚ smelting‚ disinfection‚ and Pyro processing. Even today‚ scientists

Coupled Reactions Louella Rose E. Tan‚ Frances May L. Coralde Institute of Chemistry‚ University of the Philippines‚ Diliman‚ Quezon City 1101 Philippines Results and Discussion A combustion reaction is a reaction that liberates heat and light. Magnesium is a stable element and reacts violently with evolution of much heat and light. The reason the magnesium burned in carbon dioxide was because it combined with the oxygen in the CO2 leaving elemental carbon behind. CO2(g) C(S) + O2(g)

This experimental procedure uses compounds from spinach leaves that are exposed to chromatography‚ TLC plate to indicate the different pigments within the spinach extract. ‘Column chromatography in chemistry is a method used to purify individual chemical compounds from mixtures of compounds’ (Wikipedia‚ 2011). This method is similar to thin layer chromatography‚ but the compounds in the mixture are collected separately. Green dye is used in this experiment that consists of blue and yellow constituents

WGP CHEMICAL COMPANY CASE STUDY 1. What is the total distribution cost for W-G-P Chemical Company? What is the cost per pound‚ cubic foot‚ case‚ line‚ and order? How can these measures contribute to the distribution review process? In order to calculate the total distribution cost‚ carrying cost must be calculated. Inventory carrying cost rate was given as 18%. The formula is Annual carrying cost=average inventory level * carrying cost rate Average inventory was given in table 4 as $90 million
