Boiling points essays

Boiling points essays Boiling Points and Intermolecular Forces Introduction: Intermolecular force is the force of attraction and repulsion between molecules. They are much weaker than covalent bonds. When boiling a liquid to form a gas, the intermolecular forces are broken not the covalent bonds. A molecular compound that has strong Van der Waals forces will also have a higher boiling point since more energy is required to break the intermolecular bonds. (Notes) Purpose: To test the theory and rules for London and dipole-dipole forces. Question: What trend in boiling points of the hydrogen compounds of elements in groups 14-17? Hypothesis/Prediction: According to dipole-dipole attractions attractive forces are between polar molecules which have higher electronegetivity difference. And only H2O and HF are the polar molecules in group 16 and 17 which means they have the chances of larger dipole moments in the molecules with greater attraction between molecules. Since we know that the strength of the London forces depends on the number of electrons and boiling point increases as the number of electrons increases. And as we see in the groups in each group the number of electrons increases and also the same one repeats itself, but some molecules in it are also polar like HF and H2O. And so when a polar molecule that has the same number of electrons as a non- polar molecule will have higher boiling points due to dipole- dipole forces. And thus it is predicted that the boiling point increases as the of electrons increases in each group. c) The trend in boiling points of the hydrogen compounds of elements in groups 14-17 is that as the total number of electrons increases in the same group and boiling point also increases and also as the group increases the boiling point also increases as they are all non- polar and their number of electrons also increase as it goes down the same group. But there are two exceptions in that t ...

Interview with an immigrant 4 pages single spaced Essay

Interview with an immigrant 4 pages single spaced - Essay Example Nabeeb: Learning English was really hard, especially considering that I had spoken a different language for 20 years. In Tanzania, I was accustomed to speaking the national language which is Kiswahili, in addition to my local Chagga dialect. It is very rare to find people speaking in English in Tanzania, and in fact, most people perceive English as a foreign language. Considering that I spoke very little English by the time I came to the United States, the language barrier was so much of an issue that most of the time, I did not make sense in my broken English, and people would laugh at me. Interviewer: It must have been really hard to get laughed at. How did you handle it? Nabeeb: At first, it was so humiliating. Imagine having kids as young as 6 years old laughing at you because they speak better English than you. It became so bad that I opted not to talk to people and this made me very lonely and homesick. Interviewer: So how did you overcome the language barrier issue and speakin g of home sickness, how bad was it? Nabeeb: After secluding myself for around two months, I realized that life would not get any easier if I did not take up the responsibility of fighting of the language barrier problem. I, therefore, enrolled at a local grammar school where I took up English lessons, started interacting with people and actually urged them to correct me whenever I spoke bad English. But I must say that for an immigrant, having to distinguish between formal English and American slang is an uphill task. The homesickness? No words can fully describe what it feels like to be in an alien land, away from friends and family, and forced to adapt to new life. I would get so home sick that I would spend my free time trying to find other Tanzanians who help me manage the homesickness. Communicating with my family back in Tanzania via telephone also helped ease the homesickness. However, the international calls were very expensive at the time for a student, meaning that communi cation was very rare. Interviewer: Apart from the language barrier and homesickness, what other challenges have you faced as an immigrant in the United States? Nabeeb: Once I set foot in the United States, everything was totally different. It is like waking up to a new world; the weather, the food, the modes of dressing, the accents, and more so the system of education, all gave me a culture shock. In class especially, I found the teaching methods so strange that I used to be the quietest student in class. I could not dare ask questions or even answer them. It really took me time to get adjusted to the American classroom. In addition, there are too many laws controlling the lives of immigrants that one almost feels suffocated. Obtaining a driving license, getting a work permit, travelling out of the country, getting social security, among many other regulations almost make one feel like a suspect. I must also add that it took me quite a while to get used to eating burgers and pizzas . I used to crave for Tanzanian food so much that I would try the recipes only to end up disappointed because the ingredients I found here are not the same as those used in Tanzania. Anyway, after months of complaining, I finally adjusted and I got used to the food here. Interviewer: But the experiences could not have been all bad. Is there anything positive about being an immigrant in the United States? Nabeeb: Everyone wants to live the American dream. That is what I came chasing for and that is the best decision I ever

Researched Literary Analysis - Essay Example The traditional prim pram conventions like pristine landscapes, innocent boys, loving parents, perfect mentors, and the security provided by an impeccable moral order had degenerated to the plight of some cheap and outdated joke. In contrast, the Bank’s narrative is set in a comparatively macabre ambience where the teenagers play with guns and marijuana, little girls are exposed to sexual abuse and pornography, death and violence always lurk in the background and everything ultimately seems to come down to sex and money. ‘Rule of the Bone’ appears to be a bloody spoof on the traditional notion of American Dream where the world order is defined by a burgeoning middle class whose popular idea of success hovers around cars, dish washers and the Sunday mass. Chappie, the protagonist in ‘Rule of the Bone’, if one could call him a protagonist in the true sense of the word fits nowhere in this cozy world order. Infact the only way he manages to infiltrate this sophisticated world is by breaking into a rich family’s summer house, along with his friend Russ. However, the accompanying filth and grime that seems to be his fate soon come to settle around him even in such polished quarters. Banks nowhere in his novel makes a conscious or deliberate attempt to make his characters likeable or tries to coax out the unguarded sympathy of his readers for his characters (Kakutani 2). The escapades of a teenager, who has problems with drugs, who puts in with violent bikers who love to b ludgeon homosexuals, who breaks trigger happy during fits of rage and frustration will certainly not make a good bed time story. Yet, the irony is that Banks never intends his book to be just another bed time story. On the contrary, ‘Rule of the Bone’ is a work of art that jolts the consciousness of its readers out of their cherished notions of what is acceptable

America and the challenges of religious diversity Essay Example for Free

America and the challenges of religious diversity Essay Religion and Theory Introduction   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The world today is dynamic such that there is need to recognize the diversity of the people that live in it. People across the world are different in terms of culture, religion and race. However, there are few people that have consistently failed to accommodate diverse beliefs and opinions. One of the diversity factor that has come under sharp focus is religion. All over the world, there are people with special religious sensitivities and thus the need to accommodate diverse opinions when it comes to religion. Such people should be allowed to promote and practice their religious beliefs and practices with little or no interference. However, this freedom should be limited to the fact that the said religious beliefs and practices do not infringe on the rights of other people in the society.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The practice of religious persecutions started man7y years ago when certain religious beliefs and practices were discouraged. The consequences of practicing the discouraged religious practices included harassment and illegal persecution. Today, it is very difficult to identify individuals with special sensitivities and sensibilities from the street. However, there are certain factors that are common with certain religious following. Different religious groups have different code of dressing. This might make it easier to identify an individual with religious sensitivity.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   According to Wuthnow, (2011), religious groups such as the Islamic faith require that women dress modestly. Inn more conservative Muslims, women are required to wear veils covering most of their body. This is to reinforce their religious beliefs regarding chastity and behaviour. Muslim men also wear long flowing gowns which also would make them easy to identify. Almost every ethno-religious subcultures ranging from mainstream religious following such as the Hindu to smaller ethno-religious subcultures such as the Amish have a specific dress code. However, the dressing code is not the only way that one can identify people with religious sensitivities. The important thing for every individual in the society is to learn and respect the divergent opinion of the general populous when it comes to religion. References Wuthnow, R. (2011).

Ethanol as an Alternative Energy Source Essays -- Biofuel Bio Fuel Ess

Biofuels: Ethanol an Alternative Energy Source Abstract In today's society, when someone wants to go to the movies, work, school, library, or mall, they drive to their destination. The average amount of gasoline consumed per year is about 146 gallons in the U.S. (Biofuels for Transportation, p1). Discoveries of huge petroleum deposits kept gasoline cheap for decades and biofuels were forgotten (Leen, p1). However, with the recent oil prices, along with growing concern of global warming caused by carbon dioxide emissions, biofuel regained popularity (Leen, p1). Ethanol, a renewable fuel made from plants was added to gasoline to increase octane and help the engines burn more efficiently and cleanly (West,p1). Introduction Ethanol or ethyl alcohol (EtOH) is an alternative energy source which produces a fuel with higher octane rating and fewer emissions than unblended gas (West, p1). Some sources used to make ethanol are sugar canes, maize, sorghum, fruit and vegetable waste, barley, wheat, potatoes, molasses, cotton, or any other plant that contains a large amount of sugar. But the leading U.S fuel crop is corn. Corn byproducts allow more fuel to be made from the same amount of corn by breaking down the starches in its cell walls (Benefits, p3). The enzyme Tran 2 increases production of alcohol from corn by 2% to 3% (Benefits, p3). There are four steps toward making ethanol. First, the feedstock is ground for easier processing, then when the sugar is dissolved from the ground materials, the microbes feed on the sugar producing ethanol and carbon dioxide as byproducts (West, p2). Lastly, the ethanol is purified to achieve the correct concentration (West, p3). This grain alcohol is a colorless and flammable as well as drin... ...http://journey tofor ever.org/ethanol.html>. 2.
