consider the problems of chemical use (Van Emden, 1996). Scientists and chemical manufacturers should take advice from Silent Spring. For instance, during chemical testing of substances from the water, they should also test the water from various compounds that result from the combination of different chemicals, hence the provision of safe water to humans, animals, and plants. Manufacturers should also learn from Carson and concentrate on manufacturing pesticides from natural substances. The…

All testing samples were added to testing tubes for observation. Data was collected to discover the boiling point of the liquid. The data collected through these methods was then used to determine the name and the structure of the unknown organic compound. Experimental 1. Preliminary Examination This section observed the physical…
dissolved the precipitant. The color of the solution changed from black to blue and the precipitants of the inorganic compound copper sulfate formed a salt, noting an acid-base reaction. In the process of the experiment bonds between two species of chemicals yielded the creation of products with similar bonding affiliations, which demonstrates a metathesis reaction. The elements of the compound basically interchange. The focus of the fifth cycle was to reform the copper. Zinc mesh was placed…

Eutrophication is a natural occurrence over the past centuries as bodies of water age and contains sediment (Carpenter 1981). However, due to human activities, the rate of eutrophication has increased and now plays a big role in fish kills. This happens when inordinate amount of fertilizers flow down the rivers and streams and into the sea, which in turn encourages algae and most, if not all, aquatic plants to overgrow. Fishes will then suffocate due to lack of oxygen and sunlight excessively…
What is water? Why is water vital to life? What makes water unique? Water is the most abundant compound on Earth and the universal solvent in which the chemistry of the life processes has developed over billions of years. Water has unique chemical and physical properties that make life on Earth possible; it plays a key role in the cycling nutrients on our planet and it is the only common substance that you can find as a solid, a liquid, and a gas. Water exists in every living being, it…
4.2.1. Material: Lead zirconate titanate (PZT) PZT is a short for lead zirconate titanate inorganic compound that has a chemical formula of Pb [ZrxTi1-x] O3 (0 ≤ x ≤ 1). PZT is made and composed of the two chemical elements lead and zirconium combined with the chemical compound titanate while formed under extremely high temperatures. The dielectric constant of PZT can range from 300 to 3850, depending upon orientation and doping. PZT possesses piezoelectric effect meaning that it changes shape…
Contrary to the title, the discovery of astatine was anything but a momentary process. Many scientists discovered different astatine isotopes, atoms with the same number of protons but differing numbers of neutrons, but were unable to either reproduce their results or keep the isotope in existence for any useful amount of time. After decades of possible discovery and rediscovery, astatine was officially included in the periodic table of elements with the abbreviation At and an atomic number of…
Objective The purpose of the experiment is to synthesize a compound with an organometallic iron-carbon bond and use infrared spectroscopy to investigate the unconventional sandwich structure. In addition, the experiment aims to understand pi-bonding of an arene ring, use cyclic voltammetry to understand the redox capacity of ferrocene, and explore the barriers between formal inorganic and organic chemistry definitions. Introduction Ferrocene was discovered unintentionally in 1949 when Miller…
