Introduction For the most part, the periodic table groups atoms together which are similar in structure and property. Groups or columns share similar electronic configurations, on which a variety of properties are based1. In the lab, the tested elements include those from Group 1, Group 2, Period 3, Period 4, Period 5, Period 6, and a series of metals (Calcium, Copper, Iron, Magnesium, Tin, Zinc). Group 1 elements have one valence electron and are extremely reactive. Most of the time, compounds…

The main goal is of vaccinations is to prevent illnesses and diseases. Vaccines are a type of medicine that cures and prevent illness by injecting the illness in people. This is caused by stimulating the immunity of bodies. Vaccines fight off disease by allowing a body to obtain small amounts of the virus, or a version of the virus, thus allowing it to become immune to the virus. Vaccines are made to fight off viral viruses as well as disease pathogens. Pathogens entering a body will allow the…

Vitamins and minerals are both essential nutrients that are needed by the body. Different from the macronutrients, they are said to be micronutrients by meaning that they are needed only in small amounts. Nevertheless, we should not forget about their essentiality and their importance in our daily diet1. There are two types of vitamins, fat-soluble and water-soluble. Fat-soluble vitamins include vitamin A, vitamin D, vitamin E and vitamin K. They are found in fatty foods and animal products like…

Van Tran Microbiology Tuesday 5:00 May 5, 2015 Unknown Sample # 7 1. Introduction: Using biochemical tests are a good way to identify unknown bacteria from a sample. It is basically a similar to a trial and error method, but rather than using trial and error a person would be using positive and negative results. Using biochemical tests will help a person identify certain characteristics of the unknown bacteria through a series of chemical tests. Of course more than one biochemical tests…

Purpose The purpose of this lab was to separate unknown compound 204, composed of an amine, a carboxylic acid, and a neutral component, into each of its three respective states. The unknown compound was separated using microscale separation of acidic, basic, and neutral components by liquid/liquid extraction. Liquid/liquid extraction is a very common method often used in work-ups and allows for isolation of neutral components using acid/base chemistry; this method is extremely helpful in…

Political Economy: The economy in Switzerland is one of the most competitive and stable in all of Europe. According to the Economic Freedom Index, Switzerland is the best economy in Europe, and is ranked fourth in the world. (“2016 Index of Economic freedom” 2016) Since there is a distinct lack of natural resources, Switzerland relies on a combination of a highly skilled service and financial sector, along with the exportation of refined luxury items and high end technology. The GDP of…

Acids and Bases are solutions, and can be found everywhere in the world. They can be found in food, drinks, around the house, and in the environment around you. Acids and Bases are used by people, animals, and even plants for many different purposes (Buthelezi et al. 634). A solution is a homogenous mixture, which is a mixture with a composition that is consistent throughout the substance (Buthelezi et al. 634). Solutions are comprised of the solute and a solvent. The solvent is the most…

into corresponding azides (4a-b) using sodium azide as nucleophile and DMF as solvent at 50 oC. These azides (4a-b) were reacted with 1-(prop-2-yn-1-yl)piperidin-4-one (5) by click chemistry using standard protocols of sodium ascorbate and copper sulfate as catalyst and an equimolar ratio of water and t-butanol as solvents to yield 1,2,3-triazole linker contained intermediates (6a-b). In the final step, the intermediates (6a-b) were subjected to aldol condensation with substituted benzaldehydes…
