How to Calculate pH Worked Chemistry Problem

pH is a measure of the acidity or alkalinity of a chemical solution. A solution with a pH less than 7 is considered to be acidic. One with a pH greater than 7 is alkaline. A pH equal to 7 is a neutral solution. Here is a simple example of how to calculate the pH of a solution when the hydrogen ion concentration is known: Question What is the pH of a solution with [H] 1 x 10-6 M. Solution pH is calculated by the formula pH - log [H] Substitute [H] with the concentration in the question. pH - log (1 x 10-6)pH -(-6)pH 6 Answer The pH of the solution is 6.

Diversity in the Galapagos Islands - 861 Words

If not for Charles Darwin, shown on the right, the world might not see the Galapagos Islands how we do today. The islands hold exotic and extraordinary plants and animals. Of these animals, some are going extinct or have already gone extinct. There are many varieties of natural and introduced plant life. Charles Darwin was born February 12, 1809 in Shrewsbury, England. He sailed on the HMS Beagle in 1831. He knew he was going to the Galapagos, but he didnt know that he would discover the theory of evolution. The plants on the Galapagos Island are very tropical and numerous in varietes. According to the Galapagos Conservancy there are about six hundred and forty native species of of plants on the Galapagos Islands. There are about eight hundred and twenty five introducer species. One hundred of the introduced species have become established in the wild. There are three major zones that the plants live in ; the coastal zone, the arid zone, and the highlands zone. In the coastal zone mangrove trees are very common and have an important role for bird breeding sites. The arid zone is very dry and has adapted to the drought conditions. Some of these plants that have adapted to the drought conditions are the succulent cacti and the leafless shrub, which only grows leaves in the rainy season. The humid zones are lush and green. There are mosses and epiphytes growing on trees for support.

Poverty And Ethics Essays - Libertarian Theory, Political Philosophy

Poverty And Ethics Poverty in the United States has long been a social, political, and human rights issue. Few people would say that it is not our moral duty, as social human beings to take care of those less fortunate than ourselves, to the best of our ability. I say few because there are some people out there who believe that we have no moral obligation to do anything outside of ourselves. These types of people have what is called a libertarian viewpoint. There is really no specific definition of libertarian, but it is associates justice with liberty andliberty itself with the absence of interference by other persons. In relation to the matter at hand, specifically poverty in America, libertarians are against taxing the affluent or forcing people to aid the starving and poor. One of the most influential libertarians of our time is Professor Robert Nozik. His theory of justice begins with the premise that all people have Lockean rights, which require that we refrain from interfering with others. Other than this we have no obligation to do anything positive for anyone else, and likewise, they have no obligation towards us. These rights are natural or inalienable because all humans have them and they do not come from any social or political institutions. These rights forbid us from interfering with a persons liberty even if it would promote some general good, or prevent anothers rights from being violated. Overall, the general idea is that people have the liberty to live a life free from intervention of others, and can lead their life however they so choose. In addition, he says that if a person acquired their fortune or possessions without harming, defrauding, or violating the rights of any others, then it is morally permissible to use those things however one wishes. This includes wasting, willing, or endowing the possessions to someone else. Even though many people are dying from starvation and malnutrition, Noziks theory of justice states that one has no obligation to help those people. The previous premise comes to form Noziks entitlement theory. Simply put, this theory states that people are entitled to their belongings and may use them as they wish, as long as they have fairly acquired them and have not violated anothers Lockean rights in the process. His theory is summarized as follows: 1. A person who acquires a holding in accordance with the principle of justice in acquisition is entitled to that holding. 2. A person who acquires a holding in accordance with the principle of justice in transfer, from someone else entitled to the holding, is entitled to the holding. 3. No one is entitled to a holding except by (repeated) applications of 1 and 2. Relating to poverty, libertarians feel that no matter how the actual distribution of economic holdings may look, if all involved are entitled to the holdings they possess, then the distribution is just. In addition, libertarians would be against government intervention in a society to either improve the social situation or economic situation. They feel that to tweak the economy, so to speak, would involve violating someones liberty, and therefore would make it morally unacceptable. By definition, libertarianism requires that market relations are totally unrestricted. This means that interfering with uncoerced and non-fraudulent transactions or exchanges between consenting adults is strictly forbidden. For example, a libertarian would be against government regulation of wages, since the matter of earnings should be decided between an employer and employee. Likewise, a libertarian would be against providing the poor with welfare, food stamps, and subsidized housing, because such programs are in direct contrast with their beliefs about liberty. Why is this? To them, liberty means being free in terms of the aforementioned theory of rights. All forms of public aid by definition are funded by the taxation of a countrys citizens, regardless of whether an individual wishes to support the programs or not. We, as Americans, essentially have no control over what the government funds with our tax dollars. Those supported by such aid have no right to entitlement, since they have not earned the right to the holdings by any means. Personally, I find the libertarians preference for private charity over public welfare quite disheartening.

Poety Essay

Poety Essay Poety Essay The purpose of a poem is for the author to illustrate a message to the reader. This message can be to entertain, to inform, to persuade/convince, or just to express their feelings in general. In the poems â€Å"Harlem†, written by Langston Hughes, and â€Å"Introduction to Poetry†, written by Billy Collins, both authors force the reader to examine themselves as the poem is being read. In the poem â€Å"Harlem†, the author allowed me to visualize what could happen to a dream that wasn’t utilized. On the other hand, the poem â€Å"Introduction to Poetry† symbolizes how the majority of people torture poetry. Langston Hughes does a better job with forcing the reader to examine themselves. His self- reflection has more impact on readers because of his imagination, life to words, and creativity. Imagination is the ability to think above and beyond the common. Langston Hughes does a better job at this in â€Å"Harlem† because he lists several outcomes for a deferred dream. In this poem he states â€Å"Does it dry up like a raisin in the sun?† (Hughes 1) which illustrates his imagination level to compare such a dream to a raisin that is losing its existence. In the poem â€Å"Introduction to Poetry† Collins states, â€Å"I ask them to take a poem and hold it up to the light like a color slide† (Collins 1). His imagination level is very basic in this poem compared to Hughes. Hughes imagination level is incredible for the possible dreams whereabouts. Collins and Hughes use personification to give words life in their poems. In stanza five of "Introduction to Poetry", Collins' poem states, "†¦ tie the poem to a chair with rope and torture a confession out of it" (Collins 13). This quote illustrates that the poem is no longer seen as an expressed feeling on a sheet of paper, but a victim that is accused for a wrong message. The poem is not human, but Collins illustrates how people go about criticizing what they do not know. In "Harlem", Hughes provides life to the word "dream" as he asks the question "...or fester like a sore - and then run?" (Hughes 3). It is apparent that dreams do not have legs and cannot feel pain, but Hughes just gives the dream a human characteristic that grabs the reader's attention. Both of these authors did a
