Extract of sample "Chemical Principles"

Download file to see previous pages (a) ClOF4- Cl has 7 electrons in its outer most shell. 5 electrons shared with the atoms around it while there is one lone pair. This means that there are a total of 6 electron domains. Therefore the shape is square pyramidal and the hybridization is sp3d2.
(b) (CH3)2TeCl2 It has 6 electrons in its outer most shell. 4 of them are shared with the molecules around it while 2 are the lone pairs. This indicates that there are a total of 5 electron domains. Therefore Te has an sp3d hybridization having the molecular shape of see-saw. And a bond angle of 90 and 120.
(c) ICl2- The ICL2- molecule has I as Iodine has Iodine as its central atom. The iodine molecule has 7 electrons, two of which have been donated to the Cl molecules satisfying their octet. The iodine has a negative charge, meaning that it also has eight electrons. 3 lone pairs and one shared with each chlorine. The total electron domains are hence 5 indicating that Iodine has an sp3d hybridization. The shape hence becomes linear with the angle approximately equal to 180o.

Chemical vapor deposition- principles and implementation

...?Penn EE 541, Spring CHEMICAL VAPOUR DEPOSITION Omar Alzaabi Department The Pennsylvania Park, PA 16802 Abstract Chemical Vapor Deposition (CVD) is a versatile style of creating thin deposits of metal solids on substrates. Gases are allowed into a reaction chamber which is set to optimum level conditions to allow the reaction of the gases to take place. Various adjustments on the reaction chamber produce four types of CVD: Atmospheric Pressure CVD (APCVD); Low Pressure CVD (LPCVD); Plasma enhanced CVD (PECVD) and Metalorganic CVD (MOCVD). CVD has wide applications which include provision of wear and corrosion resistance, formation of barriers and net shape components. INTRODUCTION Chemical Vapor Deposition (CVD) is a versatile technique...

Chemical sensor

Amperometric glucose sensors proves worthy in monitoring of diabetic patients’ blood glucose levels wherever they are. Such constant monitoring of blood glucose has spurred other affiliated health sector needs for improvement of the condition. It is apparent that effective treatment and management of diabetes conditions requires reliable data of glucose levels that does not fluctuate. In such needy cases, amperometric glucose sensors assist in monitoring of patients blood glucose. Monitoring of blood glucose levels presents a constant glycaemic regime that both the patient and health professional can rely on. Subsequently, health professionals can make imperative diagnosis and treatment of diabetic conditions.

Activities and Principles of Ethnography

"In it’s the most characteristic form it involves the ethnographer participating, overtly or covertly, in people’s daily lives for an extended period of time, watching what happens, listening to what is said, asking questions - in fact, collecting whatever data are available to throw light on the issues that are the focus of the research. Equally, though, as we shall suggest later, there is a sense in which all social researchers are participant observers; and, as a result, the boundaries around ethnography are necessarily unclear" (Hammersley and Atkinson, 1995, Pg 1-2)
One difficulty with the notion of ethnography is that it may seem a residual category. It is associated with the study of people, not ourselves,...

The Assessment Related Principles of Teaching

...Evaluation In the assessment related principles of teaching, the assessment toll should match with performance objective. a) Which assessment tool touse, which test to formulate must be based on our performance objective. If our assessment tool is aligned with our performance objective, we can claim that our assessment tool is valid. In the concrete, this means that if we want to teach our students how to make Shrewsbury biscuits, we simply let them work with their kitchen equipments and see them bake. Our performance test is aligned with our performance objective, therefore it is valid. If , however, we make use of a written test and ask our students to write down the steps of baking Shrewsbury biscuits, from the very beginning...

Corporate Governance: The OECD Principles of 1999

The OECD report applies mainly to those corporations whose stock is publicly traded rather than to private corporations. However, the King Report on corporate governance that was put forth in 2002 takes into account the corporate scandals that have occurred. Therefore it focuses on corporate governance within individual firms and includes the scope of Director responsibilities and duties of the Board. It also allows for the impact of technology and its impact on corporate governance. Therefore, while the OECD approach is broad-based, the approach is company-specific in the King Report. Moreover, the OECD report does not take into account individual director responsibilities or the impact of technology like the King report.

An Evaluation of the Role That the Principles of Behaviour Therapy Have to Play in Clinical Hypnosis

Hamburg (2006) first used this combined effort to treat two patients who were scared of dying. He uses his paper to encourage clinicians to refrain from not using their knowledge at the introductory classes of hypnosis but to go into it deeper. Many therapists at that time were taking the bold step of combining behavior therapy with hypnosis (Chaves, 2006). One group used hypnosis for desensitization therapy (Kirsch et al, 1995). However, there was general disagreement about the manner of hypnosis being employed and the methods of mentalist constructs. Chaves who strongly believed in the treatment combination used it as a base for many of his therapeutic interventions (Chaves, 1997a as cited in Chaves, 2006). The hypnotic therapy...
