It was concluded that the product created was paracetamol when a thin layer chromatography test was performed and observed under ultraviolet light (which is discussed further down the page). An unknown substance was treated with acetic anhydrate and resulted with paracetamol. A compound that behaves in this matter is 4-aminophenol and is widespread in the industrial production of this drug. Upon these observations was the build up of “Chemical A” decided. When 4-aminophenol is t treated with

The articles and documentary‚” Dying to be thin” were very insightful and discussed the challenges of individuals with eating disorders such as anorexia nervosa and bulimia nervosa. These eating disorders are dangerous and can be fatal. Not only are there physical affects‚ but mental affects take place as well. In the documentary‚ pressures to be thin and the “ideal” body weight were discussed amongst aspiring dancers and models. In was reported that three out of one hundred girls will develop eating

the unknown amino acid. Within experimental error‚ the results were consistent with the reference literature cited in this report. Experimental Thin Layer Chromatography The amino acid standards used in this experiment were Alanine‚ Glycine‚ Serine‚ and Histidine. These standards and the unknown were separated by performing a method of chromatography. Thin layer chromatography (TLC) was performed by using a mobile phase and a stationary phase. The mobile phase was a nonpolar solvent composed of ethanol

The works of both Atwood and Plath explore the subjugation of women through a second-wave feminist lens. Both use confessional narrative; however‚ Plath uses her own personal experiences of feeling trapped in the home only to be a wife and a mother‚ while Atwood takes us to an extreme theocratic dystopia where women are only useful for their bodies‚ their treatment justified through a religious framework. So whereas Plath examines control over women through controversial metaphors in her poetry‚

Compare the ways in which Plath and Hughes write about relationships. You must include in your response detailed critical discussion of ‘Morning Song’ and at least one other poem by Plath. Morning Song was written at the time of the birth of Plath’s first child Frieda‚ in April 1960. The poem’s title marks a new beginning and the start of the relationship between Plath and her newborn daughter‚ ‘Morning Song’. It’s a positive start to the poem and almost sounds like a nursery rhyme. The poem
