flavors‚ molecules‚ caffeine‚ etc. are extracted from the coffee beans. In this experiment‚ a solution was extracted containing a known amount of benzoic acid in water with methylene chloride‚ an organic solvent. The amount of leftover acid was determined through the titration of the aqueous‚ not the organic‚ solution with basic NaOH. This allowed the student to calculate and determine the Kd value of both multiple and single extractions. The efficiencies of both single and multiple extractions were

Identifying Organic Compounds 2. Purpose/Problem: I am doing this experiment to find out what kind of organic compounds are in test tubes A‚ B‚ C and D. I am curious to know if substance D was the lipid because it seemed thin and had a slightly yellow tint of color to it. 3. Research: In my research I was informed about facts and appearances of lipids. First of all lipids are non-polar compounds‚ thus they won’t dissolve in water. This is also known as being hydrophobic. They are made with one

Ellen Grant Honors Bio I Organic Compounds Problems and Objectives: The purpose of this lab was to select the suitable test for an organic molecule and define the safe process for that test. An organic molecule is normally found in or produced by living systems. (Unknown Author‚ 2014‚ www.biology-online.org/organic_molecule)In this lab one was supposed to infer the results of the test and be able to identify if major biomolecules are present. You were to analyze a variety of tests including

Organizational structure An organizational structure consists of activities such as task allocation‚ coordination and supervision‚ which are directed towards the achievement of organizational aims.[1] It can also be considered as the viewing glass or perspective through which individuals see their organization and its environment.[2] Many organizations have hierarchical structures‚ but not all. Organizations are a variant of clustered entities. An organization can be structured in many different

obsolescence of technology‚ structure team has become a crucial issue. Mantei suggested three generic team structure. 1. Democratic Decentralized (DD) This team structure is driven by group cohesiveness in making group decisions and solving problems with consensus. There is no group leader as such. A task coordinator is chosen for short duration based on skill or experience level. On completion of task‚ the coordinator may replaced by other. 2. Controlled Decentralized (CD) Unlike DD‚ here
