2004). It also has very low toxicity is it is used properly. Acetaminophen is cheap and easily obtainable from any pharmacy. Acetaminophen is created when the amine group of p-aminophenol is acetylated by acetic anhydride. This creates an amide functional group and the by-product of this reaction is acetic acid. The crude acetaminophen will form as a white solid after the acetylated reaction. To turn this crude acetaminophen into a purified form‚ the recrystallization technique will be used. The

Aging Positively Abstract A functional assessment of the elderly involves a multi-dimensional diagnostic process designed to evaluate an elderly individual in terms of functional capabilities‚ disabilities‚ medical and psychological characteristics. These assessment tools provide objective data to detect potential impairments among our aging populations. With these tools we are able to evaluate how elderly individuals are aging‚ what assistance is need‚ how to make sure their environment

Abstract – This multi-step synthesis uses aniline as the starting reagent to synthesize five compounds employing several reactions such as acetylation‚ diazo coupling‚ nitration‚ bromination‚ and hydrolysis. The isolated products were analyzed with TLC and spectral data that determined most products were pure while some had a few impurities indicated by GC‚ LC‚ and a wide melting point range was shown for products 2 and 3. The presence of water in product 2 and 7 was indicated by the IR. Acetanilide

According to Gresham‚ Watkins‚ and Skinner’s article in 2001‚ Functional Behavior Assessments: Principles‚ Procedures‚ and Future Directions‚ “the FBA was designed to help schools determine the appropriateness of services and placement‚ identify positive interventions to reduce the undesirable behavior‚ and develop appropriate behaviors to replace the inappropriate ones”. In addition‚ the article defined the FBA as an organized methods and strategies to collect antecedent data‚ behavior data‚ and

glacial acetic acid‚ we notice that the hydroxyl group and the oxygen on the carbonyl group will draw electrons towards themselves to a higher extent compared to the carbon which is bound to the both functional groups. Accordingly‚ the carbon will have a partial positive charge compared to the two functional groups mentioned. In nucleophilic substitution reaction‚ the electrons of the partially negative hydroxyl group of the alcohol (nucleophile) attacks the partially positive carbon on the acid (electrophile)

Functional Behavioral Assessment Ryan Williamson ECE 201 Maya Raimondi January 7‚ 2013 When it comes to adolescent children they endure several risk factors within their lives. Some of these factors often produce many glitches that have teachers speculating if there are ways they can help deal with behavioral problems that children have. Risk factors may be invisible and families may not recognize them (Kaiser & Sklar Rasminsky‚ 2012). Within this paper‚ there are three risk factors
