Using Temperature Change to Identify Exothermic and Endothermic Reactions Farah Elnemr 6/9/16 Chemistry Honors Clinton Introduction Through change in heat, this experiment was done to recognize exothermic and endothermic reactions, which both relate back to the topic of thermochemistry. Thermochemistry is study of energy changes that occur during chemical reactions and state changes. A certain amount of energy is stored in every substance in bonds. A system and its surroundings

determination of IPM and DZM drug combination by RP-HPLC method using ultraviolet (UV) detection. The chemicals methanol and water (pH between 5 and 8) were HPLC grade and were purchased from Merck chemicals private limited, Mumbai. Sodium acetate and acetic acid used in this work were analytical grade purchased from Merck chemicals,

purpose of this lab was to synthesize isopentyl acetate from glacial acetic acid and isopentyl alcohol. These two were combined to ultimately give a clear solution. When sulfuric acid was added to the solution this was where we seen the mixture turn to a brown color. Here was where a polymer was formed. The hardest part about this lab was separating all the components that were in the flask. This included acetic acid, sulfuric acid, water, and isopentyl alcohol. To isolate the isopentyl acetate we

be found in other organisms. The purpose of this lab was to synthesize the ester isopentyl acetate via an acid catalyzed esterification (Fischer Esterification) of acetic acid with isopentyl alcohol. Emil Fischer and Arthur Speier were the pioneers of this reaction referred to as Fischer Esterification. The reaction is characterized by the combining of an alcohol and an acid (with an acid catalyst) to yield and ester plus water. In order to accomplish the reaction, the reactants were

than in an open beaker would preserve more of the gaseous product. The law of conservation of mass states that mass can neither be created nor destroyed. The reaction between the baking soda, the sodium bicarbonate, and the vinegar, the dilute acetic acid, yields carbon dioxide gas, water, and sodium acetate. When the mixture is created in a beaker the carbon dioxide gas that is produced escapes through the large opening. In the plastic bag, however, the carbon dioxide gas should not escape if the

Classifying Reactions Safety Reminder: Wear safety glasses and conduct experiment in a well-ventilated area. Day 1 Materials: Part I: steel wool (HEB, Target, Lowe’s, Home Depot) You can also try SOS pads. tweezers vinegar test tube (in your kit) water petri dish (in your kit) Part II: hydrogen peroxide small pieces of raw potato (yeast or beef liver may be substituted for the potato) small bowl Procedures: Part I: Reaction between iron and oxygen 1. Break off a small piece of steel wool

temperature. In order to avoid losing any of the solvent, a water-jacketed column was used. + HEAT The product N-acetyl anthranilic acid was synthesized through the reaction of anthranilic acid with acetic anhydride, which was hydrolyzed leading to the formation of the white crystalline product. The reaction of anthranilic acid with acetic anhydride lead to acetylation of the amino group. Our percent yield

In this experiment, luminol was synthesized in the lab and used to demonstrate the result of the chemiluminescence reaction. Introduction: In criminal shows shown on television, almost common in every show are investigators inspecting crime scenes. Often when we see investigators looking for some form of a bodily fluid at a crime scene, they spray some liquid and then use a black light over the area. If bodily fluids are present, then the area appears to glow. The substance that they are spraying

Introduction In order to support and promote Iowa wines in the market place, the Iowa Wine Growers Association, assisted by the Midwest Grapes and Wines Industry Institute, has established the Iowa Quality Wine Consortium (IQWC). IQWC will help with consumer awareness and confidence in choosing Iowa quality wines. Identifying an Iowa Quality Wine An Iowa IQ Wine will have the Iowa Quality Wine seal placed on the bottle just above the right corner of main label without covering any information (Illustrated

Making Soap: Lab 1. A saponification reaction is considered to be the reverse of an esterification reaction because in an esterification, a carboxylic acid is combined with an alcohol to produce an ester and water; and in a saponification, an ester is combined with lye (Na+ + OH-) to produce the salt of a carboxylic acid and an alcohol. Essentially, the products and reactants are opposites of each other in either reaction. 2. The functional groups in glycerol are hydroxyl groups (OH). It belongs
