What Is the Strongest Acid Chemistry FAQ

What is the worlds strongest acid? Its probably not one youd guess. None of the strong acids traditionally listed in a chemistry text holds the title of Worlds Strongest Acid. The record-holder used to be fluorosulfuric acid (HFSO3), but the carborane superacids  are hundreds of times stronger than fluorosulfuric acid and over a million times stronger than concentrated sulfuric acid. The superacids readily release protons, which is a slightly different criterion for acid strength than the ability to dissociate to release a H ion (a proton). The strongest carborane superacid has the chemical structure H(CHB11Cl11).   Strong Is Different from Corrosive The carborane acids are incredible proton donors, yet they are not highly corrosive. Corrosiveness is related to the negatively-charged part of the acid. Hydrofluoric acid (HF), for example, is so corrosive it dissolves glass. The fluoride ion attacks the silicon atom in silica glass while the proton is interacting with oxygen. Even though it is highly corrosive, hydrofluoric acid is not considered to be a strong acid because it does not completely dissociate in water. The carborane acid, on the other hand, is highly stable. When it donates a hydrogen atom, a negatively charged anion left behind is sufficiently stable that it doesnt react any further. The anion is the carborane portion of the molecule. It consists of one carbon and a cluster of 11 boron atoms arranged into an icosahedron.

A Model Organism Is A Non Human Species - 1947 Words

A model organism is a non-human species that is extensively studied to understand particular biological phenomena, with the expectation that discoveries made in the organism model will provide insight into the workings of other organisms. Model organisms are in vivo models and are widely used to research human disease when human experimentation would be unfeasible or unethical. This strategy is made possible by the common descent of all living organisms and the conservation of metabolic and developmental pathways and genetic material over the course of evolution. Studying model organisms can be informative, but care must be taken when extrapolating from one organism to another. In researching human disease, model organisms allow for better understanding the disease process without the added risk of harming an actual human. The species chosen will usually meet a determined taxonomic equivalency to humans, so as to react to disease or its treatment in a way that resembles human physiology as needed. Although biological activity in a model organism does not ensure an effect in humans, many drugs, treatments and cures for human diseases are developed in part with the guidance of animal models. There are three main types of disease models: homologous, isomorphic and predictive. Homologous animals have the same causes, symptoms and treatment options as would humans who have the same disease. Isomorphic animals share the same symptoms and treatments. Predictive models are similarShow MoreRelatedThe Spandrels Of San Marco And The Panglossian Paradigm1722 Words   |  7 Pagesreason for the evolution of species. Gould and Lewontin provide a pluralistic approach of how species are evolved rather than basing on natural selection. Therefore, these scientists used the central dome of St Mark’s Cathedral in Venice to represent the other possible explanations of the evolution in species. Most importantly, Gould and Lewontin used spandrels and other findings as an analogy to parallelize the evolution of organisms as an unintentional byproduct of the species.

Ecology is a branch of biology having to deal with the relations and interactions between organisms, their environment, and other organisms.

Many plants and fungi reproduce asexually as well. While all prokaryotes reproduce asexually (without the formation and fusion of gametes), mechanisms for lateral gene transfer such as conjugation, transformation and transduction are sometimes likened to sexual reproduction. A complete lack of sexual reproduction is relatively rare among multicellular organisms, particularly animals.

By doing so, beavers increase habitat heterogeneity plus species diversity at the landscape scale. Sometimes a beaver’s activity will disturb humans and cause them to question the benefits of beavers. The question of whether beaver activity is a public nuisance or beneficial ecological restoration has much to do with people’s understanding of beavers.

Babylon Revisited Free Essays

The question of whether or not Charlie Wales’ request to have his daughter returned to him is reasonable seems fairly clear. The fact that the story begins and ends in a bar, with the alcoholic protagonist struggling with his addiction seems an indication that his demon has not been slain. Ambiguities seen in the story lead a reader to think that perhaps at this point it is not reasonable. We will write a custom essay sample on Babylon Revisited or any similar topic only for you Order Now Charlie perceives his old haunts as less than glamorous in the cold light of sobriety, but still he feels compelled to go and look once more. Yet, while it seems that Charlie genuinely regrets his past the reader also is told that Charlie has lost his fortune, which could easily be the reason for his new mindset. One of the twin themes of this story is that a person is responsible for his own shortcomings, and must pay his dues, so to speak, being held accountable to others. Charlie says that he never had a problem with alcohol until he began to lose his fortune, appearing to be in classic denial. Charlie does not accept that his bouts of drunkenness are the reason why people such as Marion behave toward him as they do. He faults Marion’s lack of compassion and her intolerance for their discord. Everyone is out of step but Johnny, so to speak, and Charlie is not willing to accept that is likely his own actions that cause the rift between them. The story ends with Charlie sitting in a bar with drink in hand, which is a dangerous act for a recovering alcoholic. Though he has refused a second one, it is clear that he is not over his addiction. His life is a tragedy, yet he has not demonstrated the ability, by story’s end, to take responsibility for his own inadequacies, so the question of his being able to care for his young daughter seems moot. For the stated reasons, Charlie is not being reasonable in asking for custody of the child. How to cite Babylon Revisited, Papers

Federal Government Reform free essay sample

Assesses alternative theories approaches to restructuring streamlining federal bureaucracy. Americans are critical of their government and their leaders and often do not make a clear distinction between the two. There is a perception in the land that government does not work as intended and that something has to be done to make government more responsive to the people. Such criticism seems to cover the political spectrum, as can be seen in the last several presidential campaigns when both Republicans and Democrats have run against Washington and against having been part of government if they can. When the Clinton administration reached Washington, one of its early efforts was overseen by Vice President Gore and was known as the National Performance Review or Reinventing Government. This was the eleventh effort this century intended to reshape the federal government and to improve the executive branch. Professors DiIulio, Garvey, and Kettl offer their..
