esterification reaction. Fischer esterification is an acid-catalyzed condensation of an alcohol and a carboxylic acid‚ yielding an ester and water. Isopentyl Acetate has the scent of banana oil‚ once synthesized it will be purified by distillation. Then the analysis of the sample using H NMR and IR will determine purity of the product. Reaction Scheme: Mechanism: Fischer esterification is the acid catalyzed condensation of an alcohol and a carboxylic acid‚ where it is protonated at the carbonyl

Kinetic energy is increasing between letters A-B‚ C-D and E-F. Based off the observations‚ in phase A-B Tert-Butyl Alcohol stays a solid‚ in phase C-D Tert-Butyl Alcohol stays a liquid‚ and in phase E-F the chemical stays a gas. This is observed at the particle level because temperature is a measure of Ek; the temperature is increasing which increases kinetic energy. Since Ek is the energy of motion‚ the particles would increase their velocity and the number and force of collisions. However‚ the

Air Conditioning Repair in Arlington‚ Texas With the arrival of spring comes warmer days‚ and as the temperatures get into the 80’s homeowners are turning on the AC. Unfortunately for some‚ they find the AC blowing warm air rather than the cold conditioned air expected. There can be a number of things causing the lack of air conditioning‚ and a few are simple fixes. Before calling Minuteman Heating & AC to schedule air conditioning repair in Arlington‚ Texas‚ check the following: Circuit Breaker

SEMINAR 12: COVENANTS IN LEASES Leasehold covenants are contractual obligations contained in leases‚ between the landlord and the tenant. There are generally 3 types: • those implied at common law in every lease‚ subject to contrary provision • those implied by statute‚ even in the face of contrary provision • those that are the result of the parties’ express agreement to that effect. A) IMPLIED COVENANTS I) BY LANDLORD A) QUIET ENJOYMENT: Every lease contains an IMPLIED COVENANT

Lipids and Phospholipids The main role of phospholipids is that they can form lipid bilayers. It is an amphipathic molecule. The head which is hydrophilic contains a group of phosphate‚ a diglyceride and a simple molecule e.g. choline. The tail is hydrophobic and is made up of fatty acids. Phospholipids receive and transmit signals across the cell membrane and act as a store room for energy. The main role of phospholipids is that they can form lipid bilayers. It is an amphipathic molecule. The

What is Psychoanalysis? Psychoanalysis is a psychological theory developed in the late 19th and early 20th centuries by Austrian neurologist Sigmund Freud. Psychoanalysis has expanded‚ been criticized and developed in different directions‚ mostly by some of Freud’s former students‚ such as Carl Gustav Jung and Jacques Lacan. The basic tenets of psychoanalysis include the following: *human behavior‚ experience and cognition are largely determined by innate and irrational drives; those drives

down molecules such as; food consumed. A person required water and enzymes to break down food. The reaction is: protein + water = amino acid + amino acid Condensation: Occurs when two molecules combine to form one molecule. This biochemical reaction is known as dehydration synthesis because water is removed from the molecule. This condensation reaction occurs in the body when you are building muscle tissue. The reaction is: Amino acid + amino acid = protein + water Oxidation Reduction (redox): Oxidation
