Arene Molybdenum lab Introduction: Organometallic chemistry is the study of chemical compounds that contain carbon atoms bound to a metal atom. Organometallic compounds can contain main group elements‚ or more metallic elements such as zinc or carbon. These compounds tend to have carbon atoms bound to the metal center by σ-bonds. Alternatively‚ transition metals can be involved in the compound‚ which leads to a variety of interesting and diverse chemical characteristics. For example‚ a promising

PCP‚ is a hallucinogenic which is normally used as an veterinary anesthetic. PCP is similar to another hallucinogenic drug‚ Ketamine‚ based on their structure and effects on the person. PCP causes a dissociative state by inhibiting NMDA receptors (N-methyl-D-aspartate). [1‚2‚3]PCP is widely abused and is seen often on the streets. The drug has various ways to be administered where it can be smoked‚ administered intravenously‚ snorted‚ or taken orally. When taken heavily‚ it can become tolerated by the

the study‚ the subjects were given AFCs (capsule A)‚ sodium benzoate (capsule B)‚ and a placebo. All participants received a random sequence of when they would consume the capsules or placebo. Capsule A included 62.4 milligrams of AFCs. There was 15.6 milligrams of sunset yellow‚ 15.6 milligrams of carmoisine‚ 15.6 milligrams of tatrazine‚ and 15.6 milligrams of ponceau 4R in Capsule A. Capsule B included 45 milligrams of sodium benzoate‚ and Capsule C included 45 milligrams of lactose‚ which served

Cola Explosion When the Mentos come into contact with the Diet Coke‚ a reaction causes the rapid formation of foam. it is concluded that the potassium benzoate‚ aspartame‚ and CO2 gas contained in the Diet Coke‚ in combination with the gelatin and gum arabic ingredients of the Mentos‚ all contribute to the formation of the foam. The structure of the Mentos is the most significant cause of the eruption due to nucleation.MythBusters reported that when fruit-flavored Mentos with a smooth waxy coating

September 10th‚ 2013 EXPERIMENT 1 LEARNING BASIC OPERATIONS: THE EFFECT OF PH ON A FOOD PRESERVATIVE Purpose: The purpose of this experiment was to investigate a competitor’s claim that the food preservative‚ sodium benzoate (C6H5COONa)‚ made by Fresh Foods International (FFI)‚ changed into a new substance in stomach acid. Stomach acid has a pH between 1 and 3 due to the hydrochloric acid content. Based on the net equation given in the book as well as the solubility of the product our hypothesis

Introduction Food preservation has long been practiced since the olden times with processes such as heating ‚ drying‚ fermentation and refrigeration. In spite of this‚ physical methods are not enough to eliminate all microorganisms found in foods. Therefore‚ antimicrobial agents are needed to destroy these foodborne pathogens‚ so that the food will have a longer shelf-life. As technology progresses‚ improvements
