Formula for Ammonium Hydroxide

Formula for Ammonium Hydroxide Ammonium hydroxide is the name given to any aqueous (water-based) solution of ammonia. In pure form, it is a clear liquid that smells strongly of ammonia. Household ammonia usually is 5-10% ammonium hydroxide solution. Other names for ammonium hydroxide are: Ammonia (e.g., household ammonia) [versus anhydrous ammonia]Aqueous ammoniaAmmonia solutionAmmonia waterAmmonia liquorAmmonical liquorSpirit of Hartshorn Chemical Formula of Ammonium Hydroxide The chemical formula of ammonium hydroxide is  NH4OH, but in practice, ammonia deprotonates some of the water, so the species found in solution are a combination of NH3,  NH4,, and OH− in water. Ammonium Hydroxide Uses Household ammonia, which is ammonium hydroxide, is a common cleaner. Its also used as a disinfectant, food leavening agent, to treat straw for cattle feed, to enhance tobacco flavor, to cycle an aquarium without fish, and as a chemical precursor for hexamethylenetetramine and ethylenediamine. In the chemistry lab, it is used for qualitative inorganic analysis and to dissolve silver oxide. Concentration of Saturated Solution Its important for chemists to realize the concentration of a saturated ammonium hydroxide solution decreases as temperature increases. If a saturated solution of ammonium hydroxide is prepared at a cool temperature and the sealed container is heated, the concentration of the solution decreases and ammonia gas can build up in the container, potentially leading it to rupture. At a minimum, unsealing the warm container releases toxic ammonia vapors. Safety Ammonia in any form is toxic, whether it is inhaled, absorbed through the skin, or ingested. Like most other bases, its also corrosive, which means it can burn skin or damage mucous membranes, such as eyes and the nasal cavity. Its also important to refrain from mixing ammonia with other household chemicals because they may react to release additional toxic fumes.

Vulnerable Population and Self-Awareness Paper Essay

Vulnerable Population and Self-Awareness Paper - Essay Example This impairs their quality of life by decreasing their subjective health and increasing depressive symptoms. Loneliness among widows could lead to cognitive decline and increased need to use health services available to them. This paper applies criteria in selecting a vulnerable population, studying the population’s demographics and reflecting on personal attitudes and values towards that population. There are over 13.7 million widowed individuals in the United States, with over 11 million of this number being women (Jenkins, 2009). Female survivors have outdistanced the men by an increasingly widening margin with women now representative of eighty percent of the population of widows in the US. In 1940, there were approximately twice as many widows as there were widowers, with this ratio climbing to 4:1 and expected to continue rising in the future. Several factors can explain this disparity between the two sexes. First, women have a longer lifespan compared to men with women living into their advanced years more than men do. Second, most men will marry women who are younger than they are, which increases their probability of outliving their spouse. Thirdly, widowers tend to remarry more than their female counterparts do; therefore, men tend to leave widowhood more than women do. 65% of women aged 65 and above are widowed, which reflects their greater life expectancy (Jenkins, 2009). Widows also undergo longer periods of grieving accompanied by feelings of guilt and retrospection of a past relationship mistakes. Before the demographic research, my view of widows was one of grief and loneliness. It seemed me that they were, in too much grief, to reconsider marriage due to their attachment to their late husbands or even out of respect to their children and the memories that they held of their late father. It also seemed that widows complained all the time, especially when in public. This was especially so with elderly widows who came to social meets by the mselves. I thought that they had no more reason to complain than widowers did, some of whom I knew personally to be very affable characters. However, after this demographic study, it is now clear that widows have very limited chances of remarrying. Despite their loneliness and want for companionship, by the time they get to 65, there are very few men available for re-marriage. The emotional loneliness that they experience is a subjective response to lack of intimate and close attachment. When they lose their husband, who was an intimate attachment, their identity becomes impaired since they have no one to foster a feeling of security, which leaves them in a state of isolation and aloneness. The demographic study also brought me closer to their social isolation. Whereas I thought they were socially isolated because of unending grief, it became clear that this was caused by lack of a social networks, or even dissatisfaction with their present social network. A lack of social integrati on makes them feel that they do not have friends. Social researchers feel that social isolation is can be measured by contacts and integration the widow has with the surrounding social environment (Owen, 2009). Healthcare professionals are in good positions of helping the elderly women suffering from loneliness, which in turn, leads to suffering from health problems. However,

Perception of the power of language Essay Example | Topics and Well Written Essays - 750 words

Perception of the power of language - Essay Example The power of language therefore depends on an individual’s perception which encompasses a collaboration of values, beliefs and experiences that person has encountered in one’s life. In this regard, the essay aims to proffer one’s personal perception of the power of language. By initially providing a definition of the term language, one would eventually delve into the role that language played in life. UniXL, an education and career information portal, defines language as â€Å"a system of communicating with other people using sounds, symbols and words in expressing a meaning, idea or thought. This language can be used in many forms, primarily through oral and written communications as well as using expressions through body language† (UniXL, par. 2). When differentiated with communication, per se, tool of verbal communication using words to express the message being relayed. Communication, per se, is defined as â€Å"â€Å"process of transmitting thoughts, feelings, facts, and other information† through verbal or non-verbal means (Delaune and Ladner. 475). Verbal messages are messages communicated with the use of words and language. These messages can either be spoken or written. Non verbal communication, on the other hand, is the process of transmitting messages without words, that is, through body language (Delaune and Ladner, 480). Mead (1934) averred that â€Å"language makes it possible to replace behavior with ideas. Non verbal communication in conjunction with social interaction assisted in the development of the human potentials of language† (87). Language for me has been recognized as a crucial tool to facilitate understanding. Aside from one’s native tongue, it has been inculcated that English, as the international language understood by majority of people around the world, should be embraced as a second language where skills must be honed, both in communication and in writing. Teachers in primary

The important moment in the novel Lord of the flies Essay Example for Free

The important moment in the novel Lord of the flies Essay Lord of the flies focuses mainly on the corruption and inherent evil of humanity. Ralph, Jack and Simon are, in some ways, stereotypes of different aspects of human nature. Ralph is the obvious candidate for chief of the island, as he is of just nature and a commanding presence. We are also told that there was a stillness about Ralph that encourages the boys to elect him as their chief. Jack represents the darker side of humanity. Jack is not long in severing any links with civilisation. He heeds his savage, pre-historic instincts, and becomes dog-likeon all foursnose only a few inches from the humid earth. He is like an animal, his sole desire being to kill the pig. Cut her throat. Spill her blood. He enjoys the act of killing, announcing proudly that he had a smashing timeI cut the pigs throat. He laughingly adds that there was lashings of blood every whereyou should have seen it! His darker side gradually influences Ralph, who grows jealous of Jacks popularity and is envious of the fact that Jack is able to provide meat for the boys, while, he, as chief, cannot. The book reaches a turning point at the next, improvised, hunt of the boar. What started as a harmless exploration for the beast becomes a bloodthirsty chase of the boar. Ralph is delighted when he hits the boar and the spear stuck in a bit and he decides that hunting was good after all. Things take a more sinister turn when the boys decide to re-enact the hunt. After the first, successful hunt in which Jack kills the pig, the hunters replay events by forming a ring, Maurice pretended to be the pig and ran squealing into the centre, and the hunterspretended to beat him. This is harmless game, during which the hunters dance around the pig, singing their hunting chant of Kill the pig. Cut her throat. Bash her in. The corruption of purity and goodness is seen when the boys play the same game after their next (failed) hunt. This time Robert is the squealing pig, trapped in the centre of circle, the hunters circling him, singing their warrior chant. The game soon ceases to playful, as Roberts mock terror turns to pain. The others are seized with a desire to Kill him! Kill him! uncaring of the fact that Robert is human, one of them, and not a pig. Robert was screaming and struggling, yet he ceases to become a person and is now merely an object by which their thirst to kill might be quenched. Jack was brandishing his knifeRalph was fightingto get a handful of that brown, vulnerable fleshthe desireto hurt was over-mastering, Golding causes this to be important incident in the novel, the beginnings of a full realisation of Simons belief that maybe there is a beastmaybe its only us, is not a comment to be jeered at, for it is a frightening comprehension of reality. Robert escapes with a few, physical injuries, crying out, in an effort to lighten to the situation Oh, my bum! Ralph tries to convince that it was just a game, like rugger. This uneasiness is justified when the boys discuss methods of improving their game. Robert believes that they want a real pigbecause youve got to kill him. Jack, not altogether jokingly, suggests that they should Use a littlun. This suggestion is made more disturbing by the reaction of the other boys, for instead of being horrified, everybody laughed. Goldings brief ending to the passage leaves us disgusted by the callousness of Jacks remark and of his flippant attitude to the murder of a fellow human being, but it is worryingly representative of the callousness humankind. Jacks joke warns us of the increase of evil on the island, for the idea of using a littlun, may soon stop being an idea and become a reality. The passage is disturbing because we see that the boys lust for blood and death is indiscriminate of whether their victim is an animal or human. Killing is not a means of providing food for the boys; it is a way of satisfying their longing to cause pain and destruction. They are desperate to kill, a mere pig is not enough, they are not worth the trouble of a hunt, and their next victim shall be a human, for it will increase the enjoyment of their game. The boys do not care for the adventure of the hunt. They want only the exhilaration of killing, the sight of the blood and the joy of controlling the existence of another being. In order for a pig to be killed, it must first be found. The hassle of a search can be avoided by substituting the pig with a human. It is almost inevitable that the boys gratify their lust with human blood, perhaps with the blood of a littlun. The game is a horrifying example of how evil humanity can be. The dark side of human nature thinks nothing of killing a friend. We are shocked by Ralphs longing to cause pain, Jacks desire to stab Robert with his knife and Roger fighting to get close. But the thing that frightens us the most is the fact that this is not a figment of Goldings imagination, Ralph, Jack and the other islanders are not irrelevant fiction, for human kind is capable of great evil. I feel that the passage in the book is disturbing because it shows us how horrifyingly able we are to be unfeeling and cruel.

American Identity Essay -- History Indians Historical Essays

American Identity Works Cited Not Included American identity has been created by many events throughout the course of history. This country was founded on the clashing and mixing of many different cultures and lifestyles. One of the most important periods of time for this country was during the period of conflict between Americans and Native Americans over land rights. Americans had an idea of manifest destiny and that this land was theirs for the taking. The Americans were going to walk through anyone who opposed them in this quest for land. The treatment of the Indians during this time period was harsh, cruel, and violent to say the least. It is in this treatment that Americans came to view the Indians as a ?racialized other? and where race began to matter. This early thinking is what created our American identity which is based on race.   Ã‚  Ã‚  Ã‚  Ã‚  In the early settling of this country, when the English first encountered the Indians they viewed them as uncivilized beasts. ?The first English colonizers in the New World found that the Indians reminded them of the Irish? (Takaki, 28). To the English the Irish represented a lower and uncivilized class of people, a group that the English considered to be beneath them. This association was the beginning of creating an ?Indian Race.? The Indians were different then Irish in they had a reddish tint to their skin. This was important because this lead further to their separation by their color. The Indians were further looked at as...

Decisions Essay

Decisions in 2006 regarding discrimination in the workplace centered largely on a theme of time and evidence. The court regularly held that the evidence of discrimination must be clear and that the legal action must be filed in a timely manner. The idea that a person can have been the victim of discrimination for years and have taken no action was dismissed as untimely. A case alleging racial discrimination was held to have insufficient proof of intent and in another case the court held that a union suing an employer for prejudicial hiring practices also did not submit sufficient proof. Finally, the court held that when an employer takes discriminatory action it does not have to be within the confines of the workplace to be discriminatory. First, in a case against Good Year Tire and Rubber Company, the plaintiff claimed that in her 18 years with Good Year, she had routinely been paid a smaller wage than her male counterparts. A local jury awarded her damages based on a series of wage-related decisions going back 19 years. However, the 11th Circuit Court held that the plaintiff’s lawsuit was untimely in that her complaint was not based on actions taken in the last 180 days according to the summation of Ledbetter v. Goodyear Tire & Rubber, 421 F. 3d 1169 (11th Cir 08/23/2005) (Runkel, 2007. The court did not rule on the merit of the case, but held that the statute restricts the time frame in which the alleged discrimination was to have occurred (Runkel, 2007). The plaintiff has appealed the decision to the U.  S. Supreme Court and in May, 2007, Justice Samuel Alito writing for the court, affirmed the lower court’s ruling â€Å"Ledbetter v. Good Year†, 2007). Next, in case versus Tyson Foods the court held that use of the term â€Å"boy† is not enough proof of racial animus to sustain a ruling alleging discrimination, but reverse a portion of the lower court’s ruling which had claimed that a racial descriptor was required to accompany the word to prove animus. In Ash v. Tyson Foods, 126 S. Ct. 195 (02/21/2006), the court wrote, â€Å"†Although it is true the disputed word will not always be evidence of racial animus, it does not follow that the term, standing alone, is always benign. The speaker’s meaning may depend on various factors including context, inflection, tone of voice, local custom, and historical usage. Insofar as the Court of Appeals held that modifiers or qualifications are necessary in all instances to render the disputed term probative of bias, the court’s decision is erroneous. (Runkel, 2007). That means the court needs more information that just a word to determine discrimination. The court ruling says that to prove discrimination, the plaintiff must show more than just a misjudgment by the hiring authority of perceived qualifications. It must show that ‘disparities of qualifications must be or such weight and significance† that a reasonable person could not have made the hiring decision which was made (â€Å"Ash v. Tyson, 2006). This decision dovetails with the court’s decision in IBEW v.  Mississippi Power & Light, 442 F. 3d 313 (5th Cir 03/02/2006). The union had argues that the employer’s standard for employment was discriminatory in that the cut-off point on the standardized tests was inherently discriminatory. The court did not dispute the merit of the claim, but ruled that the burden of proof lies with the plaintiff and that the union had failed to prove that there was another way that the employer could adequately determine employment eligibility. (Runkel, 2007) Finally, the court held that when an employer is accused of retaliatory action, it does not have to be limited to the confines of the work environment. In Burlington Northern v. White, 126 S. Ct. 2405 (06/22/2006), the court upheld the defendant’s claim that her employer had retaliated against her by moving her from one position to another and by initially trying to suspend her without pay, requiring that she file a grievance through the union to receive reinstatement and her back pay. The court held, â€Å"We conclude that the anti-retaliation provision does not confine the actions and harms it forbids to those that are related to employment or occur at the workplace. We also conclude that the provision covers those (and only those) employer actions that would have been materially adverse to a reasonable employee or job applicant. In the present context that means that the employer’s actions must be harmful to the point that they could well dissuade a reasonable worker from making or supporting a charge of discrimination. (Runkel, 2007). The court further held that retaliatory practices do not have to include financial loss to be actionable. (Runkel, 2007) The overwhelming effect of these court ruling on future graduates is a trend within employment law toward the defense of the employer. These cases tend to indicate that the court has placed the entire burden of proof on the employee when it comes to discrimination cases and expects that the employee can make a clear case for their claim, rather than relying on vague innuendoes, such as in the Tyson case. For employees, this can be a difficult precedence in that other employees are unlikely to back a person’s claim regarding workplace discrimination especially when they would then have such stringent requirements in proving their own retaliation case. This is also likely to have a chilling effect on employees who feel they are being mistreated because of the burden of proof. The reality is that for any African-American man, the mere use of the word boy is inflammatory, especially in the south. Though the word was not accompanied by any racial descriptor, the court held that intonation and other context can be used to determine the word’s intent. For an African-American in the South, that is the context and proving what his supervisor was thinking places too great a burden on the plaintiff. The Tyson case in particular makes it difficult for a person who is the victim of subtle racism to prove it and the Ledbetter cases reiterates that the person must deal with any perceived discrimination within 6 months of its occurrence, compounding the difficulty in proving a case.
