Determination of Melting and Boiling Point of different Organic Compounds Bakare‚ Abimbola Kristine‚ C. Professor Miranda Marilyn‚ school of chemical engineering and biotechnology‚ Mapua Institute of Technology‚ CHM145L-B11 ABSTRACT A melting point of a solid is the temperature at which the first crystal just starts to melt until the temperature at which the last crystal just disappears. Thus‚ the melting point (m.p.) is actually a melting range. The melting point of a substance depends

CHE 173 Sec # January 25‚ 2005 Experiment 36: Determination of the Structure of a Natural Product in Anise Oil Purpose: The purpose of this experiment is to isolate the major component of anise oil and determine its identity and structure using melting point determination and IR spectroscopy. Introduction: The major component of anise oil has the chemical formula C10H12O. This compound is said to be hydrogen deficient‚ meaning that it contains less hydrogen atoms than would be needed for each

Canada prides itself at home and abroad as a country made up of a cultural mosaic rather than a cultural melting pot. The mosaic is based on our belief that Canada as a whole becomes stronger by having immigrants bring with them their cultural diversity for all Canadians to learn from. The cultural melting pot‚ as adopted in the United States‚ tells immigrants that no matter who they have been in the past‚ upon landing on American shores‚ they are Americans and are expected to adopt and follow the

filtration and melting point. Chm237 Abstract: Acetaminaphen was crushed then extracted for the active ingredient by mixing it with methanol. Then separated from the binders by centrifugation and a filtration technique using a Pasteur pipet packed with alumina. The remaining solvent was then evaporated to yield the solid analgesic(.2295g‚ 45.9% yield) which was collected by filtration and tested for the purity of the drug by the melting point determination. The melting point was

Recrystallization Experiment 2: Recrystallization & Melting Point • Most important method for the purification of organic solids • Separation of compounds based on differences in solubility between the compound of interest and its contaminants • Basic technique: 1. dissolve impure sample in an "appropriate" hot solvent Part A: Choosing a Solvent Part B: Purification of Phenacetin 2. cool solution slowly to induce crystal growth 3. filter resulting mixture to isolate crystals Reading:

The point of this essay‚ “The Chinese in All of us” by Richard Rodriguez‚ was to show that America is one giant melting pot. That there is no such thing as an “American” culture. An American culture cannot exist as one central thing because there are so many cultures that mixed together to form what we have now. It’s a never ending cycle of growth as a country. The immigrants come to America and with them‚ they bring their ideas and customs. While they learn the customs we already have we‚ in turn

Research Paper First and foremost‚ the freezing point or melting point of water is the temperature at which water changes phase from a liquid to a solid or vice versa. The freezing point describes the liquid to solid transition while the melting point is the temperature at which water goes from a solid (ice) to liquid water. In theory‚ the two temperatures would be the same‚ but liquids can be super cooled beyond their freezing points so that they don’t solidify until well below freezing point

Every story has a conflict‚ conversely not all have winners. In “Seventh Grade” the conflict is internal. A character will consider an idea within themselves. This idea may be conflicting‚ but it stays inside. In “Melting Pot” the conflicts are external. External conflicts take place externally with other people. In the passage “Seventh Grade” the conflict is Victor conflicting internally. He wants to be able to chatter Teresa without giving off the impression that he likes her. Also‚ Victor

the melting glaciers poses a direct threat to my home. Island nations and coastal cities will suffer the inevitable if we do not act now. In six degrees‚ Mark Lynas warned the impending arctic tipping point‚ once passed‚ the melting of the glaciers cannot be reversed‚ leading to a loss of habitable environment. However‚ I believe that the situation is worse than what Lynas anticipated. Despite some efforts from the international to curb the increasing carbon emissions‚ glaciers are melting faster
