All the materials were purchased from Sigma-Aldrich and used as received unless otherwise stated. Reaction (1) How to make Sodium Azo-Tetrazolate--Pentahydrate (SAT) Approximately 2.15 g of Aminotetrazolate monohydrate was added to approximately 62.5 ml of 2 M sodium hydroxide. While being stirred, the solution was heated, increasing its temperature up 10 degrees Celsius, up to 60 degrees Celsius. Over a one hour time period, potassium…

The role of enzymes play a large role in the survival of organisms through catalysis of reactions that keep them alive and functioning. The purpose of this experiment was to measure reaction activity over time and how substrate concentration affects their activity level. A supernatant was made through the dilution of blended potato extract. Then the supernatant was mixed with catechol and the reaction rate was measured in units of absorbance through a spectrophotometer every 30 seconds for ten…

In A Doll’s House, by Henrik Ibsen, people today can clearly see how Torvald mistreats his wife Nora. He treats her like a pet and calls her by little nicknames that are not appropriate for someone such as your wife. For example in the opening scene he says to her, “Is it my little squirrel bustling about?”(Ibsen), this is something people today find to be completely sickening but then it was a thing that was common and accepted. During the time it was written people acted in the exact…

and leave one at room temperature. Allow the tubes to sit for a while, then compare the tubes and record any differences. If there is enough time, allow the tubes to warm/cool down to room temperature and record any observations. Dispose of the chemicals into the proper…

earth`s surface. Chemistry can relate to chemical reactions, one of the chemical reactions that occur is the creation of acidic rain. It can also relate to sublimation after the sinkhole occur, and to the rocks in a sinkhole and what they 're made of. One of the chemical reactions that occur that is based upon hydrogen and carbon dioxide is “H2O(l) + CO2 9(g) -> H2CO3 (aq)’’ (Brian Rohig). The outcome of this equation is acidic rain. In chemistry we use chemical equations to show how…

a site upstream from Goomboora Park. This site will be referred to as, Site 1. Measurements from Site 1 will be analysed and compared to water qualities recorded from previous years (2012, 2013, 2014, 2015). Water is a triatomic molecule, with a chemical formula of H20. At a temperature…

Chemical, biological, radiological and nuclear (CBRN) weapons, also referred to as weapons of mass destruction (WMD), continue to pose a significant threat to all living things on earth. WMD are very different from conventional weapons. These weapons can be used in several different ways and the effects can range from environmental destruction, to incapacitating humans or animals, or even killing them. The Department of Defense (DOD) Strategy for Countering Weapons of Mass Destruction is…

The company I have selected to evaluate for its Corporate Social Responsibility (CSR) is Chase. This powerful banking organization has been a cornerstone in the banking world for years and given the already tepid public opinion towards wealthy institutions it is no wonder that Chase has been listed on American 's list of the most despised companies. Recent developments have not aided their case. In the ensuing essay, I will evaluate various aspects of the business as well as explain where this…

Use of microbial platform overexpressing such an ideal O-methyltransferase having flexibility in its catalytic activity over different classes of substrates is of great importance in producing variety of methylated natural products. With this concept, we used the aforementioned natural compounds as substrate for biotransformation reaction. Culture of recombinant E. coli strain was prepared and induced as explained in materials and method. In vivo reaction mixtures analysis of different…

Along the lines of rate laws come half-lives. Such a common topic that comes to mind with half-lives is the decay of radioactive elements, or the time it takes for a certain sample of an element to reach half of its original size. For example, during the Chernobyl power plant incident in 1986, one of the most dangerous elements to begin its decay was Cesium-137 which has a half-life of 30 years. Therefore, people can’t move back to the area because of the deadly amounts of Cesium-137 still…
