Beginning Question: How effectively and efficiently can biphenyl be synthesized by a Suzuki coupling reaction? Claims: Biphenyl synthesized by a Suzuki coupling reaction was effectively isolated and then characterized using TLC, melting point, IR and 1H NMR tests. However, this process was not efficient because it had a poor pure yield of 22%. Evidence: The goal of the experiment was to synthesize biphenyl product by a Microwave-assisted Suzuki reaction and this was carried out using 1…

Can Fireworks Explode without Being Lit? Fireworks exploding on the night sky is a majestic sight. These explosives look stunning but they are still just that, explosives. In order to enjoy them, you want to keep in mind the safety rules and follow instructions. But could something go wrong? Can fireworks explode without being lit? How do fireworks work? Fireworks come in different types from rockets to wheels. But each firework will have a fuse, which is the main part of the firework in…

Benton Smith April 26th, 2018 PES 4520 Improving a Poor Lawn Soil Soil fertility is the foundation for healthy grass. Improving soil quality can be more challenging on an established lawn rather than growing a new one. The most important thing for soil is air and water and their ability to be absorbed by the roots. This helps nutrients to be absorbed also. A degraded soil typically loses its ability to supply food and habitation to living organisms, in it’s surrounding. Characteristics of a…

widely used in very large quantities as fertilizers in agriculture because of their readiness to decompose and release nitrogen for plant growth and because of their ready solubility ensuring that nitrate ions can be absorbed by plant root hairs. (NOAA). Nitrate compounds have a wide range of uses which rely on their activity as oxidizing agents, the presence of freely available nitrogen, or their high solubility (NOAA). Expain how nitrate is produced in nature and in manmade means and how…

Vulcanizing mold To form a tread on green tire, a mold must mold and melt the rubber. The inside circumference of the circular tread face part of the mold that will be in contact where the tread of the green tire will be is a negative shape of the tread to be on that green tire to be shaped. The outside of the circular tread face is in contact with the pre-heating or curing molds inside circumference. The tread shapes on the tire is formed by ribs and/or lugs on the inside of the circular…

are the four molecules all living things need to survive. The four molecules are Proteins, DNA, Carbohydrates, and Lipids. Each of these molecules is made of Carbon, Hydrogen, and Oxygen at the very least. Proteins have Nitrogen as an added element, and DNA has Phosphate and Nitrogen. The base structure of each molecule has a carbon skeleton. This means that structures have Carbon as the base, in diagrams the carbon skeleton will have many bonds but you can recognize it because it will be in the…

The objective of this study was to investigate the impact of changing soil textures and nutrient availabilities upon biomass allocation within Brassica rapus. From the data collected, we can conclude that soil texture and it’s influence upon nutrient availability is significant in determining biomass allocation within B. rapus. In our study, we found that soil texture primarily determined root biomass while the degree of nutrient availability, provided by fertilization, primarily determined…

measure out compounds accurately, mix the compounds in DI water until they are dissolved, test pH levels, effectively add acids or bases depending on pH level, and administrate EDTA when a precipitate has formed. When only components that include 0.06g Nitrogen, 0.0497g Phosphorous, and 0.0399g Potassium are combined, on the first day of the experiment, a very basic solution with a pH level of 13.0 formed. The addition of 18 droplets of hydrochloric acid lowered the pH level to 6.0. When…

possibility is that in monoculture for higher urease activity, N-fertilizer rate was same in monoculture and intercrops, and intercrops utilized soil urea faster than monoculture. Nitrite reductase, protease and nitrogenase play significant roles in nitrogen cycle and higher activities of these enzymes showed that vital microbial community enhanced in intercropping system. The nitrogenase enzyme catalyzes the reduction of atmospheric dinitrogen to ammonia. This process is energy expensive and…

My second critical response essay is on the reading Getting Fossil Fuels Off the Plate by Michael Bomford. This reading is about how food is grown, processed, and transported around the world and how much energy it takes to get food from its origin to your plate. Our aptitude to obtain food with ease is our most treasured resource, but regrettably our present structures of food production, especially agriculture, are causative to the failing strength of the world’s air and water, while…
