Identification of Unknown Organic Compounds by Melting Point‚ Boiling Point‚ and Infrared Spectroscopy Methods and Background The goal of this laboratory experiment was to determine the structure and identity of an unknown solid and an unknown liquid by using elemental analysis‚ index of hydrogen deficiency‚ infrared spectroscopy‚ melting point (for solid)‚ and boiling point (for liquid). In this laboratory‚ we were given unknown solid “C” and unknown liquid “D”. The empirical formula

concept of fast food has born. Food that can be prepared and serve in a spilt of a second. So that customer can come eat and continue their business in the time much faster than eating in a regular diner. Nowadays‚ fast food is so common in the society that a lot of people will consider going to a fast food outlet when they don’t have time to prepare a proper meal‚ or they simply don’t know what to eat and just want to have a quick meal. Since the early 20th century‚ fast food had had a big impact

In Haiti‚ acute poverty forces the population to rely on wood and charcoal for fuel and income‚ leading to ever more deforestation. Sixty-six percent of Haitians depend on agriculture and small-scale farming‚ but most cannot produce enough food on the eroded hillsides to even feed their families. When tropical storms regularly hit Haiti‚ rainfalls

Drama 88 Day 4 The Gap between Developed and Developing Countries The main topic of this week’s reading that stood out to me was The Global Table where Foer shows a glimpse of the status of the all the countries in the world. Foer says that if all the countries were to sit on a table with a seat of nine‚ two would be Chinese‚ two Indians‚ a fifth would be the other countries in Northeast‚ South‚ and Central Asia‚ a sixth would be the nations of Southeast Asia and Oceana‚ a seventh would be sub-Saharan

impurities have on the melting point of an organic compound? Soluble impurities affect the melting point of a solid in the following manner. a. The presence of an impurity in the molten compound reduces its vapor pressure thus lowering the melting point of the compound. b. Broaden the melting point range. 2. For what tow purpose are melting points routinely used a. To determine the identity of an organic solid. b. To determine the purity of an organic solid. 3. What effects on the measured melting

customers get consistent product quality. As Porter’s 5 Forces analysis deals with factors outside an industry that influence the nature of competition within it‚ the forces inside the industry (microenvironment) that influence the way in which firms compete‚ and so the industry’s likely profitability is conducted in Porter’s five forces model. A business has to understand the dynamics of its industries and markets in order to compete effectively in the marketplace. Porter (1980a) defined the forces

of an alcohol in the presence of a catalyst. Calculate the percentage recovery of products. Test for purity and identification of products. Abstract Cyclohexene and cyclohexanol are both colourless aromatic compounds. The major difference between the two is the presence of the hydroxyl group present in cyclohexanol. This hydroxyl group can be removed by a process known as dehydration which results in the production of cyclohexene at the end of the dehydration process in the presence of a catalyst
