Kurt Vonnegut was academically proficient; he completed his preliminary education from short ridge High School in Indianapolis in 1940. Then he went to Cornell University, where he studied biology and chemistry as a major subject. At Short ridge High, Vonnegut wrote for the students paper, The Echo and he continued his interest in journalism at Cornell, becoming the Managing Editor of the student paper, The Sun. Vonnegut writings are crisp and he is known for his declarative style, much like…

stannic oxide in the older notation, is the inorganic compound with the formula SnO2. The mineral form of SnO2 is called cassiterite, and this is the main ore of tin. With many other names, this oxide of tin is the most important raw material in tin chemistry. This colorless, diamagnetic solid is amphoteric. 1.2 Structure It crystallises with the rutile structure, wherein the tin atoms are six coordinate and the oxygen atoms three coordinate. SnO2 is usually regarded as an oxygen-deficient…

Discussion For the first part of the experiment, a solubility test was conducted on all compounds. Because they were all ionic, every known compound naturally dissolved in water, and conducted electricity. As the next determining factor in the process to identify the unknown substance, the compounds were tested in acetone. As seen in table 2, only one compound, Ca(NO3)2 was found to be soluble in this solvent. Because the unknown solid was insoluble in acetone, Ca(NO3)2 was then eliminated as a…

Environmental Education & Sustainability in Schools Many school districts are debating whether or not to include some form of environmental education in their curriculum. Environmental education not only benefits student health and knowledge, but encourages them to develop into citizens who are prepared to make a positive impact in local and global communities. According to the United Stated Environmental Protection Agency (EPA), “Environmental education is a process that allows individuals…

the highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) at B3LYP/6-311G** level of calculations using Gaussian 03 program package [32, 33]. Thus, this principle is pretty beneficial for the utility of electron chemistry, due to the fact HOMO /LUMO potentials involve the capabilities of proton transfer or unshared pair/empty orbital…

Calcium hydroxide (Ca(OH)2), universally referred to as lime water or slaked lime is formed by reacting hydrated lime (calcium oxide, CaO) with water (H2O)[1] CaO (s) + H2O (l) ⇌ Ca(OH)2 (aq) (ΔHr = −63.7 kJ/mol of CaO) Calcium hydroxide is an economically favorable alkaline reagent to neutralize acid as it yields 2 moles of (OH)2 for every 1 mole of Ca(OH)2 (which is slightly soluble in water) when compared to sodium hydroxide [1] and it may separate from the solution ‘constant agitation must…

Love Canal Sophie Albright The Love Canal tragedy, in 1942, caused conflict and stirred up arguments, socially, economically, and environmentally. Unwanted chemicals from various experiments and projects from different companies and groups were dumped at a waste site in Niagara Falls, New York, thinking the landfill would cause no harm. The chemicals were then, out of sight, out of mind. When the area was turned into a neighborhood, it then became evident those discarded…

Pure Copper Iodide were synthesised and the mass percentage of Copper in purified Copper (I) Iodide sample were determined by applying Beer’s Law in UV-Vis spectroscopy. Absorbance value of Cu-cuprizone solution was measured. Using the absorbance value of 0.3576 , the concentration of the Cu-cuprizone solution were obtained at 0.001389g/L with reference to the graph of the standard solution A to D. The graph of absorbance against concentration of the standard solution A to D shows a linear…

The goal of this experiment was to use chemistry to analyze an unknown compound and through testing its physical and chemical properties determine what unknown compound that was found in a landfill. This would benefit the Environmental Protection Agency because once they know what the substance was they could determine the best way to remove it from the landfill and if there were any potential safety hazards to beware of while handling the substance. This would prevent any accidents that may…

Why BioGreen? Most of the companies now a days are looking for ways to become environmental-friendly to improve its bottom line. BioGreen understands the need of maintaining the natural ecological balance in the environment and so, we came up with the biodegradable products. In order to eliminate the mess, our biggest challenge and responsibility was to develop green products, services and processes that will provide better quality air, a cleaner environment, and a better health. Biodegradable…
