Peroxide Definition and Facts

A peroxide is defined as a polyatomic anion with molecular formula O22-. The compounds are generally classed as ionic or covalent or an organic or inorganic. The O-O group is termed the peroxo group or peroxide group. Peroxide also refers to any compound containing the peroxide anion. Examples of Peroxides Hydrogen peroxide, H2O2, is a simple peroxide compound.Other inorganic peroxides (aside from hydrogen peroxide) are known. These are classified as either ionic peroxides or covalent peroxides. Ionic peroxides contain alkali metal ions or alkaline earth ions as their cations. Covalent peroxides include hydrogen peroxide and also peroxymonosulfuric acid (H2SO5).Technically superoxides, ozones, ozonides, and dioxygenyls are peroxide compounds, but they tend to be considered separate because of their special characteristics. Peroxide Occurrence and Uses Peroxides occur naturally in small amounts in plants and animals, water, and the atmosphere. In humans and other animals, hydrogen peroxide is a by-product of biochemical reactions. The chemical is short-lived but is toxic to cells because of its ability to oxidize DNA, proteins, and membrane lipids. This toxicity makes peroxide useful as a disinfectant, to kill bacteria and other pathogens. However, nearly all eukaryotic cells purposely form peroxide in organelles called peroxisomes. Peroxisomes are used for catabolism of fatty acids, D-amino acids, and polyamines and for biosynthesis of compounds essential for normal lung and brain function.The enzyme catalase uses peroxide to oxidize substrates to neutralize toxins in the kidney and liver cells. In this way, for example, humans are able to metabolize ethanol into acetaldehyde.Plants use hydrogen peroxide as a signaling chemical indicating defense against pathogens.Some peroxides can bleach or decolorize organic molecules, so they are added to cleaning agents and hair colorants.Peroxides are widely used to synthesize drugs and other chemicals.The bombardier beetle stores hydroquinone and hydrogen peroxide in abdominal reservoirs. When the beetle is threatened, it mixes the chemicals together, resulting in an exothermic reaction that enables the beetle to squirt boiling-hot, smelly liquid at a threat. Peroxide Safe Handling Most people are familiar with household hydrogen peroxide solution, which is a dilute solution of hydrogen peroxide in water. The type of peroxide sold for disinfecting and cleaning is about 3% peroxide in water. When used to bleach hair, this concentration is called V10. Higher concentrations may be used to bleach hair or for industrial cleaning. While 3% household peroxide is a safe chemical, concentrated peroxide is extremely dangerous! Peroxides are potent oxidizers, capable of causing serious chemical burns. Certain organic peroxides, such as TATP (triacetone triperoxide)Â  and HMTD (Hexamethylene triperoxide diamine), are highly explosive. Its important to understand these highly unstable compounds may be made by accident by mixing together acetone or other ketone solvents with hydrogen peroxide. For this, and other reasons, its unwise to mix peroxides with other chemicals unless you have full knowledge of the resulting reaction. Peroxidic compounds should be stored in opaque containers, in cool, vibration-free locations. Heat and light accelerate chemical reactions with peroxides and should be avoided.

John Updike s A P And James Joyce s Araby - 1877 Words

Coming-of-age is a chapter that every individual must inevitably trek through in order to grow and mature into one’s own self. In John Updike’s AP and James Joyce’s Araby, the theme of growth permeates throughout both narratives as their respective protagonists fabricate an ideal world from their own naive perspectives, only to shed their ignorant fantasies about how they believe to understand that the world can bend to their decisions to truly understand the cruelty behind world they live in: reaching maturity through the loss of innocence. Dismissing the pragmatic aspects of life can lead to the downfall of a person’s ideals as they eventually come to the realization that their dreams are impractical, and even impossible to bring to†¦show more content†¦Instead, after overcoming obstacles like his apathetic uncle and the work of school, the boy arrives in Araby during closing time. After witnessing the store clerk’s lack of interest in hi m as a customer, he decides not to buy anything and then, upon his failure, he realizes how his crush will be fruitless through a negative epiphany. The boy inevitably understands the futility of his actions, as if the entire world was acting against his efforts to impress the girl he was obsessed with; his determination is suppressed after making it so far and failing at the final step of his mission. The inciting hope that the conversation instilled in him combined with the obstacles he had to overcome, only made his failure all the more bitter, but this harsh failure is the turning point that the boy needed in order to escape the childish and naive infatuation that he was experiencing. Failure was the lesson that made him understand that his love will remain unrequited, a realization that is the prerequisite for his sexual maturity. In a similar fashion, John Updike’s AP portrays the mundane life of a cashier named Sammy who works in a grocery store called AP. Sammy observ es the people around him — customers and fellow employees — and refers to them as â€Å"sheep† because of their conformity to society.

The People vs. Larry Flynt - 1332 Words

Freedom of expression has always been a heated and heavily debated topic throughout our society, more so in recent times due to the increasing amount of freedoms that we gain. However, it is only natural that free speech be something of extreme amounts of conflict since this right is expressed in the very first amendment of the Constitution. But, how loosely should such an important document within our history be interpreted? This has been a question for years, and it is obvious that this particular amendment presents itself through our day-to-day activities.

According to Mills, if this political right is infringed upon, it is completely justified that resistance occurs, as it did. Mills goes on later in his work to state, â€Å"†¦there needs to be protection also against the tyrant of the prevailing opinion and feeling; against the tendency of society to impose†¦its own ideas and practices as rules of conduct on those who dissent from them; to fetter the development†¦of any individuality not in harmony with its ways, and compel all characters to fashion themselves upon the model of its own.† (Mills 116) By Mills bringing up the idea behind falling into society’s stereotypes and expectations, it is further validated that one should not be silenced, whether literally or figuratively, due to society’s â€Å"discomfort.† Individuals should not be forced into the fads in which society finds accep table.
