To illustrate the contrast of light and darkness‚ Banana Yoshimoto begins with detailing Hiiragi as radiant and glowing. Hiiragi‚ although still reeling from the sudden deaths of both his girlfriend and his brother‚ seemed to always be “gaily illuminated” (Yoshimoto‚ 120) and often “smiled brightly” (118)‚ especially during scenes where Satsuki appeared. Hiiragi’s “bright eyes” and “childlike” personality reference Yoshimoto’s portrayal of him as a character of innocence. Yoshimoto continues to develop

DRY ICE Introduction The topic I have chosen to write this report on is dry ice (also known as liquid nitrogen). This topic has quite an interest to me in a sense that I am curious about the dry ice as a whole. I have seen it being used but always thought about the manufacturing behind it. I am hopeful in finding out information such as what exactly dry ice is‚ how the dry ice is made/formed‚ what it has use for‚ and who was behind the making or discovery of dry ice. Some questions that I

Rency J Group 5 18L I. Introduction Due to the demand of certain reagents in the laboratory in order to perform and conduct further experiments or produce essential compounds‚ chemists continuously develop organic synthesis. This process aims to prepare and synthesize desired organic compounds from commercially or readily available ones by providing the simplest route in synthesizing the compound. One example of a compound being can be synthesized in the laboratory is acetylsalicylic acid‚ commonly

Sources of Organic Fertilizers and Amendment Abstract: Fertilizer is one of the most important things for agriculture & crop production. But here we go to discuss about the sources of organic fertilizers. Here we try to inform about different types of organic fertilizer and sources. We also like to discuss here about different structures and functions of organic fertilizer and soil amendment. We show a guide line; by that our farmer can improve production system through organic fertilizers.

In his essay soap powder and detergents in “‘Mythologies’ Barthes describes about the myths of French daily life and explain how the media contributed to form the myths. According to barthers the advertisement and media repackage the popular idea so that it become selling. Barthes introduces the subject of soap-powders and detergents by identifying the benefits and the aim. For instance‚ the detergents have the possibility to save miners from silicosis. Then he gave

Background The melting point of a compound is the temperature at which the solid is in equilibrium with its liquid. A solid compounds changes to a liquid when the molecules acquire enough energy to overcome the forces holding them together. A mixture melting point is useful in confirming and used to indentify an unknown compound‚ which we will be doing in this particular experiment. Purpose Measure the melting points of pure benzoic acid and pure mandelic acid. Determine the eutectic composition

COMPARATIVE INVESTIGATION OF ORGANIC COMPOUNDS Abstract Organic compunds were examined to a comparative investigation to differentiate the properties of each sample. The physical state at room temperature‚ odor and color of the sample were noted by simple observation. In terms of solubility in H2O‚ 5% NaOH solution and 5% HCl solution‚ the samples were classified as to miscible‚ slightly immiscible or immiscible for liquid; and very soluble‚ soluble‚ partially soluble or insolubse for solid.
