Reaction(s)‚ including molar masses and all relevant physical data E.) Mechanism for the nitration of chlorobenzene: II. Purpose: In this experiment we are to take a cold solution of an aromatic ester that is first dissolved in sulfuric acid and is then reacted with nitric acid. This is a highly exothermic reaction and is kept under control by means

H2SO4 were combined to form a nitrating solution‚ which was mixed with a mixture of methyl benzoate and H2SO4. Percent yield for the final product was calculated followed by recrystallization and melting point was measured. Introduction: Nitration of Methyl Benzoate is one of the examples of Electrophilic aromatic substitutions. The use of a mixture of Sulfuric Acid and Nitric Acid is the classic way to make NO2+. The two main reaction types used for this are both substitutions: Electrophilic

A Beautiful Mind with an Ugly Mental Disorder Submitted by: Nazila R. Salamkhail V-00410030 Psychology101-901 Instructor: Tim Donahue Virginia Commonwealth University 04/27/2011 The movie “A Beautiful Mind” is a fascinating movie. Although‚ I am not a movie watcher‚ it drew my full attention as soon as I started playing it. It displays the character of a great mathematician John Nash who is struggling with schizophrenia during his college period

Control mechanisms are important to every organization. Without them‚ it would be difficult to determine whether or not the planning‚ organizing and leading functions of management are effective and productive for the company. Although some mechanisms are used widely throughout many organizations and companies‚ some mechanisms are tailored to fit a specific organization. Management must determine the most appropriate control mechanisms for their company. In this paper‚ we provide a brief description

Defense Mechanism Defense Mechanism is an unconscious psychological strategies brought into play by various entities to cope with reality and to maintain self-image. Healthy persons normally use different defenses throughout life. An ego defense mechanism becomes pathological only when its persistent use leads to maladaptive behavior such that the physical and/or mental health of the individual is adversely affected. The purpose of ego defense mechanisms is to protect the mind/self/ego from anxiety

Name: Monish Kumar (S11065194) The University of the South Pacific MM313 Dynamic Systems Experiment 2- Crank Mechanism Aim: To investigate the relationship between piston displacement and crank angle for different ratios between the connecting rod and the crank. Also to look at the relationship between the turning moment on the crank shaft and crank angle for a given force on the piston. Equipment and Instrument: Introduction: A crank is an arm attached at right angles to a rotating

airstream mechanism is the method by which airflow is created in the vocal tract. Along with phonation‚ it is one of two mandatory aspects of sound production; without these‚ there can be no speech sound. The organ generating the airstream is called the initiator; for this reason the production of airflow is called initiation. There are three initiators used in spoken human languages: the diaphragm together with the ribs and lungs (pulmonic mechanisms)‚ the glottis (glottalic mechanisms)‚ and the
