Environmental chemistry

“Chemical engineering is a branch of engineering that applies physical sciences (e.g. chemistry and physics) and life sciences (e.g. biology, microbiology and biochemistry) together with mathematics and economics to produce, transform, transport, and properly use chemicals, materials and energy (Cohen, 1996).” The field of chemical engineering is very diverse, covering areas from biotechnology to mineral processing. It would take too long to list all the products that are impacted by chemical…

The Reaction of a food dye with bleach Introduction The overall purpose of the experiment was to determine the order in respect to the blue dye and the rate constant (K). With these found however, the overall rate law in the reaction between blue food coloring and the bleaching agent within commercial Clorox can be found. The orders in a rate law equation represent the relationship between the concentration of a given element or molecule and the overall rate, for example, when a reaction in…

and chlorine dioxide. The main results obtained in this study are based on the simulations and quantitative data about change in concentration in time. This is one of the nice examples of the use of this technique for solving general and applied chemistry problems that have strong impact on industry and engineering. The same technique was used for the investigation of the explosives and explosive-related compounds, in the work by Mullen and…

Introduction: Discipline investigation is an essay that allows a student to discover the difficulties of professional life. The main source for this essay is the interview that student uses to collect the empirical data. From my opinion, this dissertation is a study to convince students to either follow what they choose or change their career. Before doing this assignment, I expected chemical engineering is a tough profession in the industry but I found out the academic courses were challenging…

What is Styrofoam? Styrofoam is a brand of closed-cell extruded polystyrene foam currently created for thermal insulation and craft applications. Dow Chemical Company retained and produced the Styrofoam. Through petroleum product known as styrene, Styrofoam was created. The styrene is amended into a clear molten mass of polystyrene through a complex chemical process known as polymerization. It would become a hard plastic if it were left to cool. Disposable eating utensils are created from this…

Given an unknown compound in container 3, solubility tests, cation tests, anion tests, and conductivity tests can be used to determine the various properties of the unknown to then make a positive identification of the unknown. These results will not only show chemical and physical properties but also what the unknown compound might react with to form other compounds. After performing the four anion tests, a positive identification was able to be made showing that the unknown compound contained…

Water quality of Freshwater Creek Abstract: This report will be detailing the results found after testing three different water quality parameters on water samples taken at Freshwater Creek and comparing them with past results. It will determine if Freshwater Creek is, has been or is becoming polluted. The three tested parameters were dissolved oxygen, biochemical oxygen demand and ammonia. What was found is that the results for all three tests fitted within the recommended guidelines for…

Identification of an Unknown Compound to Determine Proper Waste Procedures Department of Chemistry, Michigan State University, East Lansing, MI 48823 October 13, 2015 For completion of CEM 161 Section 009, under supervision of Abstract: In order to determine the identity of the compound we performed many experiments with a solution of the compound. These experiments included testing for all of the following ions; ammonium, halide, sulfate, carbonate, nitrate, and acetate…

environmentalist is the NAEP. The NAEP is the National Association of Environmental Professionals which was born in 1970 following the landmark legislation of the environmental profession on January 1st, 1970 (naep.org). The bible also consecrates the profession in a sense in Proverbs 27:18 it reads “Whoever tends a fig tree will eat its fruit, and he who guards his master will be honored.”. The interpretation of this verse in the sense of environmental scientist it is saying that all humans…
