Green Synthesis of Ibuprofen Green Chemistry is a new approach and perspective of chemistry that can improve human lives and maximize efficiency. It is a branch in chemistry that explores and examines techniques to reduce and eliminate hazardous and harmful substances. These harmful substances effect humans and the environment in multiple ways, the twelve principles of Green Chemistry can help minimize them. The twelve principles include prevention of waste, the design of less hazardous…

Experiment 5: Anions and Redox Reactions Introduction (a) Objectives General: To examine the importance of potassium permanganate as an oxidising agent and the strong powers of halogens in oxidation. Part 1 Determining the colour associated with a certain halogen by adding a sample of the halogen to cyclohexane and recording the colours observed. Part 2 Identifying a halogen referring to the colours recorded in part 1, by reacting the halogen with a halide and observing the colour present.…

Due to the clay’s eco-friendly and acidic nature, it was possible to utilize it as an acid catalyst for the dehydration reaction.4 The use of Montmorillonite K10 is an excellent example of green chemistry as it not only shows the use of catalysts to increase efficiency but also displays a less hazardous form of chemical synthesis. The cyclohexene collected from the first experiment served as the starting material for the next reaction of the cycle…

Sulfur: Research Paper by Brian Zhang 805 If you ever happened to unnerve a grumpy skunk, then you would have understood the severe atrocity of its scent firsthand. What you probably didn't realize, however, concerns the fact that sulfur holds much blame for the nasty occurrence. In fact, this mother of repulsive odors earns its spot on the periodic table as one of the world's 118 chemical elements, or substances that contain only one type of atom. Much like any other non-metal, it does…

If, indeed, it is true that a person undergoes change as a result of learning, then I can safely say that my peers and I have all undergone a profound transformation over the last fifteen weeks. As far as the nature of this transformation is concerned, I would argue in favor of it being a positive change for all of us, not only the students in my section, but also for all the students who took the course this semester. Initially, this thought might come as a surprise to some, especially those…

Collective Learning Technology has brought huge influences on everyone’s lives. The Duke University had brought iPod as an academic device and educational experiment to all the first-year class students. The iPod inverted the traditional role of technology, which has many new functions. Students not only can listen to music, but also use the iPod as an academic device to collaborate with others. This concept can be seen in Project Classroom Makeover, by Cathy Davidson. In Project Classroom…

Identifying an Unknown Compound Using Various Chemical Analysis Techniques Joshua Nash and Aquilla Young Abstract The introduction of this lab report exposes the reader to the different scientific concepts that are to be used such as melting point calculations, retention factors, and solubility in various aqueous solutions. The experimental provides the basics of using a melting point apparatus, determining solubility, and performing thin layer chromatography. In the results section the findings…

to make long distance calls and cell phones which allow us as humans to talk wirelessly to people in another country. It allowed for sturdier infrastructure, cars, and electronics. Copper allowed for the evolution of life. Copper is high in most organic foods. That means this food was able to support early organisms. Copper is an important element in agriculture. It is in all soil and is key to the plants growing in this soil that allows crops to grow. Copper is formed in stars and is key to the…

Abstract: Chemiluminescence is an essential topic in the study of chemistry. The reaction involves mixing two chemicals were to form an excited (high-energy) intermediate that releases energy as light. This experiment first synthesized luminol by reducing 5-nitro-2,3-dihyodropthlazine-1,4-dione, using sodium hydrosulfite (Na2S2O4) and 3M sodium hydroxide (NaOH). The amount of luminol collected was 0.2693 g with the percent yield of 161%. The product of the first reaction was then used to…

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…
