composer challenged you? Imagine this: you are only fourteen and raped by the man you call ‘father’. You have no one to turn to‚ fearing for your mother’s life‚ and even your own. Well‚ this is Celie’s harsh reality in Alice Walker’s novel The Colour Purple‚ a story about one African-American girl’s struggle to overcome racism‚ sexism and repression in pre-civil rights Southern America. Walker challenges and extends the understanding of readers through exploring confronting issues like female

Distillation Introduction: The recrystallization technique you learned last lab is a method for purifying solids. This week we will learn how to perform a distillation‚ a method for purifying liquids. Distillation is a common wet-chemical technique for separating organic compounds based on differences in boiling points. Upon heating a mixture of organic compounds‚ the more volatile compounds (those with the lowest boiling point) will vaporize first (i.e. be converted to gases)‚ leaving the higher-boiling

Introduction: This experiment involves an extraction of a natural product using the techniques of steam distillation. The principle component of oil of cloves is an aromatic compound‚ which is identified by thin layer chromatography (TLC). Eugenol is widely used in dentistry‚ due to its analgesic‚ antiseptic balsamic qualities. It is ideal for curative for pulp hyperemia (the soft‚ sensitive substance underneath the enamel and dentine of a tooth) and pulp its. In dentistry eugenol is also used to

The understanding of light and the effective use of colour in creative work and digital p photography. People effectively using colour in creative work and digital photography has been around for a long time now‚ and the study of light and colour even longer. In this essay I plan to effectively communicate how the human brain perceives light and how the understanding of this has culminated in creative work

Extraction is a method used for separating and isolating materials. A compound is pulled from solvent A to solvent B and in this case‚ both solvents are miscible. These two concepts are not capable of mixing together; when they are mixed together‚ they form a bilayer. This can be seen when mixing oil and water together. When thinking of extractions‚ one can picture how coffee gets extracted. The flavors‚ molecules‚ caffeine‚ etc. are extracted from the coffee beans. In this experiment‚ a solution
