Chemistry - Term Paper Example Identification by mass sets this element as the third-most abundant element in the universe after elements of hydrogen and helium. Representatively by dry air volume, oxygen forms about 20.9476% (209,460 ppmv) of the atmosphere by volume at the sea level temperatures of 150C; thus, making it the third largest compound. Understanding the composition of oxygen and its molecular composition is essential in its incorporation to further chemical uses given that it is a primary atmospheric industrial gas product. For instance, given that one has 32 grams of oxygen, this will be equivalent to one mole of Oxygen gas while 16 grams of the same would be a representation of Oxygen element. This implies that the molecular mass of Oxygen is 32 grams while its atomic mass is 16 grams. By ratio compared to dry air, Oxygen forms about 23.20% of the atmospheric air by weight and has a boiling point of -182.950C. Oxygen forms about 85% of the earth’s elements such as oceans, and is a component of most minerals and rocks given that 46% of these rocks and minerals comprises of Oxygen. Subsequently, the compound forms about 60% of the human body mass. Oxygen as a chemical compound possess distinct properties such as being colorless, being tasteless and odorless. Oxygen also has the property of being poorly soluble in water. A particular gravity of 1.105 is enough to make oxygen be slightly heavier than air. When the Oxygen is cooled to its boiling point of -1830C, it turns appearance and becomes a transparent, pale blue liquid that has a slightly heavy weight than water. Oxygen as a compound can react with all elements, excluding the inert gases resulting in the formation of oxides through a varied reaction rate (oxidation). Even though oxygen in itself is non-flammable, it enhances the combustion process; thus, enabling all flammable materials to burn vigorously. The use of oxygen in industrial

The Immigrant Experience - Essay Example ead it deals in a matured manner, and analyses the complex relationship between a mother and daughter, while exploring family relationships, female intuitions, and various other interrelated subjects, against the backdrop of sexual and political violence. At the end, the novel speaks of a possibility of emotional healing, even within the realms of death and destruction. The message that this book sends out, is that, for complete emotional healing one must go beyond all political reasoning, and allow the inner self to grow and metamorphose, while coming to terms with one’s traumatic past. Dandicat dedicates her first novel to all the â€Å"brave women of Haiti, grandmothers, mothers, aunts, sisters, cousins, daughters, and friends, on this and other shores† (Dandicat, 5). This novel that portrays the travails of the lead protagonist Sophie, forges a link between the four generations of women within a family, by finding a common thread of suffering and abuse. This story with its strong political and emotional dimensions, delves into the mother-daughter relationship, and seeks to find solace at the end through various processes of self examination and self expression. There is also the complex correlation of an individual with his mother land. This is evident in the story, when we learn that Sophie was conceived when her mother was raped by a member of the Tonton Macoute (political goons in Haiti) in a cane field, which allegorically also refers to the exploitation and abuse of Haiti, the motherland. The story also portrays a community that cherishes its heritage, which speaks of courage and survival, and a strong will to fight back oppression. This heritage is transmitted through their story telling, and we see this when Sophie’s grandma tells her â€Å"if you see a lot of trouble in your life, it is because you were chosen to carry a part of the sky on your head† (ibid, 25). This tradition of storytelling to pass on the heritage is also evident in mythical
