Ronnie Green Informative Abstract June 28‚ 2011 Image gap is the difference between how a person wants to look and sound compared to how they are actually viewed by others. Projecting your desired image can build trust and is critical to successful communication. Projecting an inappropriate image‚ however‚ can erode trust and cause others to doubt your abilities. Four components of your overall image are your projected first impression‚ your depth of knowledge‚ your breadth of knowledge‚ and

Synthesis of Aspirin and Tylenol Kyla Wykoff Abstract Aspirin and Tylenol were synthesized by means of crystallization‚ recrystallization‚ and melting point determination. Synthesis produced significantly high percent yields for aspirin‚ however‚ produced extremely low and impure percent yields for Tylenol. A second group was also used to compare results and errors‚ in which they too were also producing extremely low percent yields of Tylenol. Therefore‚ error was based on the specific protocol

Table 1. An infrared spectrum for the pure aspirin from the synthesis was taken by using crushed crystals‚ Figure 1. This spectrum was shown with different absorption bands corresponded with the functional groups of aspirin which was observed at frequencies > 1500 cm-1. These infrared frequencies were shown in Table 2. An infrared spectrum of an authentic aspirin was used to distinguish how authentic the infrared spectrum from the synthesis was shown in Figure 2 In this lab‚ aspirin was synthesized

SYNTHESIS OF ESTERS USING GREEN AND NON-GREEN CHEMISTRY Abstract Esters are a class of organic compounds with the general formula RCOOR’. Ester also contributes the flavor and aromas in fruits and flowers. The esterification reactions will use in the procedure‚ which are the interaction of a carboxylic acid with an alcohol‚ aided by an inorganic acid catalyst (H2SO4). Moreover‚ the green method will not use any catalyst but using heating source instead (microwave). Based on the comparison of

Using Sucrose Solutions to Determine Osmolarity of Potato Tubers Based on Weight By Thomas Pelikan Biology 200A Section 004 Kimberly Schmidt October 2‚ 2012 Abstract: In this experiment we were trying to determine the osmolarity of potato tubers by weighing them before and after incubating them in solutions of sucrose with varying molarities. To find the osmolarity we took a potato and used a cork borer to obtain seven samples of potato tubers. We then prepared seven beakers with concentrations

Mental Disorders in the Criminal Justice System Mental Disorders in the Criminal Justice System Abstract The purpose of this research is to identify and explore mental disorders in the criminal justice system. It has been said that there is a substantial increase in the number of offenders with mental disorders in the justice system‚ instead of them being sent to mental institutions where they can receive help. The mental health system agrees with this statement;

Protein synthesis is one of the most fundamental biological processes. To start off‚ a protein is made in a ribosome. There are many cellular mechanisms involved with protein synthesis. Before the process of protein synthesis can be described‚ a person must know what proteins are made out of. There are four basic levels of protein organization. The first is primary structure‚ followed by secondary structure‚ then tertiary structure‚ and the last level is quaternary structure. Once someone understands

was filtered and recrystallised from ethanol. 4.6.General procedure for Preparation of the N-methylation of piperidin-4-one oximes: The piperidone (0.1mol)was dissolved in ethanol(50ml). saturated solutions of hydroxylamine hydrochloride and sodium acetate in water were added. The mixture was refluxed on a water bath for one hour. Then it was cooled ‚ poured into water and the solidoxime obtained was filtered. All the oximes were recrystallised from ethanol. S.
