Linoleic acid

The main principle of manufacture of urea has two main reactions. 2NH3 + CO2 NH2COONH4 -37.4 Kcal/mol NH2COONH4 NH2CONH2 + H2O + 6.3 Kcal/mol While going main reactions, the undesirable side reaction taking place is 2NH2CONH2 NH2CONHCONH2 (Biuret) + NH3 This process is further complicated by the formation of a substance called biuret, NH2CONHCONH2, which should be kept low because it adversely affects the growth…

Claim, Evidence and Reasoning Graphic Organizer Question: Are Fat and Soap Different Substances? Claim: Fat and soap are different substances. Evidence (from your data) Solubility - Fat was soluble in oil. Soap was not soluble in oil. Fat was not soluble in water. Soap was soluble in water. Reasoning (why does the above piece of evidence support your claim?) The above piece of evidence supports my claim because it proves that in the same substance (H2O), fat and soap have different…

[mol/dm3] sulphuric acid was added to the flask, and shaken well with the stopper. The name of the members and the date was written on the flask, and was left for a week for the iron sulphate tablets to fully dissolve in the acid. After the tablets have fully dissolved, the whole solution was filtered using a filter paper and a funnel into a 100 [cm2] volumetric flask. The remaining residue in the filter paper was rinsed with a small amount of distilled water. Then, sulphuric acid was added to…

all the different types of reactions because they often refer the reactions as being of one type or another. The first reaction is Acid-base (Neutralization) Reaction. A neutralization reaction occurs when an acid and base are mixed together. The compound formed by the cation of the base and the anion of the acid is called a salt. The combination of hydrochloric acid and sodium hydroxide produces common table salt. An example is…

Introduction: Kidney stones are an extremely basic urinary issue. Also known as renal calculi, kidney stones are characterized by their high occurrence and a high repeat rate. This issue results from the arrangement of insoluble salt stores in the urinary tract and inside the kidney. The rate of this issue has expanded in the course of recent years for reasons that are not entirely known, but have caught the consideration of numerous scientists. There are different types of kidney stones, each…

In this experiment, a Grignard reagent, phenylmagnesium bromide, reacted with a ketone, acetophenone, to produce 1,1-diphenylethanol. The experimental product was relatively pure as its melting point was determined to be between 78 and 80.7°C. The value from literature suggests that the melting point is between 78 and 82°C (chemspider.com). However, the percent yield for this experiment was not very high, at only 57 percent. The low yield for this lab was most likely due to the low…

The purpose of this lab was to perform the condensation of acetic acid with isopentyl alcohol in the presence of sulfuric acid. Isopentyl acetate was formed from this reaction and this compound has the distinct smell of bananas. This reaction is known as Fisher Esterification. From the final product, the final mass was used to calculate the percent yield. Finally, the IR spectrum was obtained from the final product in order to determine if the reaction went to completion or not. To a 5mL…

Background: Acidic rain or acid deposition is predominantly caused by air pollution. Acid deposition in the form of gasses and microscopic particles, floating in the air, is called dry deposition. However, wet deposition is in the form of precipitation. As a result of chemicals being released from human productions, great amounts of sulfur dioxide and nitrogen dioxide are respired into the atmosphere, where rain and gas matter is polluted. Once both sulfur dioxide and nitrogen dioxide come in…

recorded. Each Alka Seltzer contains the same three ingredients: 325 mg of Aspirin, 1000 mg of Citric Acid, and 1916 mg of Sodium Bicarbonate. Two of Alka Seltzer’s ingredients, Citric Acid and Sodium Bicarbonate (Baking Soda), were both placed into a beaker to see if both contents could cause a potential reaction. The final result was a non- occurring reaction. For a second test, both the Citric Acid and Sodium Bicarbonate were placed into separate, dry beakers. Afterwards,…

Component Via Extraction Objective: Separation of organic acid from a neutral compound using liquid/liquid extraction. Experimental: Similar to the “Thin Layer Chromatography” experiment, a TLC plate was ran with 2 ml of EtOAc and 8 mL of hexane in the jar. The Rf value was calculated using the formula located in the data for all the TLC plate. The mixed compound that was dotted on the TLC plate had 0.300 g of the impure benzoic acid and 10 mL of dichloromethane. A 50 mL flask was weighed…
