Inorganic compound

One of the qualities of lead that make it one of the most highly studied heavy metals is its ability to enter and distributes into the body’s organ systems. Inorganic lead is absorbed by coming into contact with the skin, ingestion, and inhalation.* It is debated whether ingestion of lead or inhalation of lead caused the most significant damage and which one occurs more frequently. The physiological effects of lead can be seen soon after exposure. The uptake of lead in the body is influenced by…

Compare and contrast the crystal structures and crystal chemistry of quartz, α-FePO4 and β-FePO4. FePO4 is also known as Iron (III) phosphate. Iron (III) phosphate is an inorganic compound. Most of the FeP04 has the structure of α-quartz which is α-FePO4. It has a tetrahedral molecular geometry. α-FePO4 is present at pretty low degree Celsius. It is also a transition metal as it is in the d-block in the periodic table. It can be studied at many different temperature which range from 294K to…

Mixed contamination of PAHs and metals occur ubiquitously in the environment, but their combined toxicity to humans and other organisms are not fully addressed. The data from epidemiological, animal and in vitro studies indicated the nature of interaction between PAHs and metals varies from synergism to additivity or antagonism. In this chapter, the combined toxicity of PAHs and metals on toxicokinetic and toxicodynamic endpoints, and possible mechanism of actions were discussed. In addition,…

Introduction: The purpose of the tests (culture media, motility, enzymes, etc.) we preform on the numerous bacteria in lab is to show any biological or chemical characteristics of the bacteria that may help it survive or adapt in the wild, how it may be useful or hazardous to humans, and use as general knowledge to differentiate bacteria from each other. In the Culture Media test we can use solid and liquid media to grow multiple bacteria in lab. It can help us determine what processes the…

Chemistry relates to everything you could possibly think of on the planet. They relate to every object and every natural event and hazard. Such as sinkholes, there a very intimidating and scary event that could happen at any moment . Sinkholes occur when the limestone beneath us breaks away by acidic rain and eventually the ground gives creating an open hole in our earth`s surface. Chemistry can relate to chemical reactions, one of the chemical reactions that occur is the creation of acidic rain…

persisted? Smith addresses this question with one simple answer. There is a hierarchy of organisms that feed into necessity. Autotrophs and heterotrophs are a prime example of this hierarchy. Autotrophs are able to synthesis their own food using inorganic material. Heterotrophs are then able to feed off of either the autotrophs themselves or off of what they produce because their molecular chemistry is incomplete. With this hierarchy going, life is able to persist with stability and allow new…

Ryan Schoen Mrs. Lily Gu Protein Project - function October 20, 2014 Lysyl-tRNA Synthetase Lysyl-tRNA Synthetase has a couple known names, one of them being aminocyl tRNA. The major role of this protein is translation during protein synthesis. For a protein to be classified and placed into an amino acid group, its amino acid sequence must be properly translated. Transfer RNA helps translate the protein which helps with genetics. Aminoacyl tRNA synthetases are the enzymes that are responsible…

category e film. As in a typical category e film, the status quo is firmly presented as the central theme at the beginning of the film. A system influenced by capitalism becomes the central ideological theme that is driving the film’s storyline. What compounds the capitalist ideology, by using apparatus theory, is the construction of hierarchy. However, what takes away from this consideration of this film as a category e, is whether the process has dramatically changed; the resistance to the…

Crystalline and Amorphous Solids  Solids can be divided into two classes: crystalline and amorphous. Crystalline solids have well-defined edges and faces, diffract x-rays, and tend to have sharp melting points. In contrast, amorphous solids have irregular or curved surfaces, do not give well-resolved x-ray diffraction patterns, and melt over a wide range of temperatures. Crystalline solids, or crystals, have distinctive internal structures…

layer) that help combat the ignition through chemical reactions at particular phases in the combustion cycle. Fire retardants are classified as reactive (which is combined into polymers through chemical reactions) or additive (combined into the compounds through physical mixing). Fire retardants composite of the following…
