Atomic mass unit Essay Example for Free

Atomic mass unit Essay Substance Z is sodium carbonate because the relative atomic mass of X calculated is 22. 99. The actual relative atomic mass of sodium is 22. 99. Hence, we can conclude X is sodium. 6) If de-ionized water was added into the volumetric flask beyond the calibration mark, the exact concentration of the solution of standard Z will decrease but the number of moles of substance Z will still remain the same. Assuming that the volume of the solution of substance Z made is still 250 cm3, the number of moles calculated in that 250 cm3 solution of substance Z will be less because of the decrease in concentration. When the number of moles calculated decreases, the mass of one mole of substance Z will increase because of the equation (). Number of moles is inversely proportional to mass of one mole of substance Z or relative molecular mass of substance Z. 7) If an air bubble is initially entrapped in the burette tip and is passed from the burette during the titration, the recorded volume of HCl used will increase although the actual volume used to reach the end point of the titration is still the same. The calculated number of moles of HCl used will increase. The number of moles of Substance Z calculated will also increase. The calculated mass of one mole of substance Z will be lower because of the equation (). The number of moles is inversely proportional to the mass of one mole of substance Z or relative molecular mass of substance Z. Discussion Element X was correctly identified as sodium and substance Z is sodium carbonate. The relative atomic mass of element X was accurately determined. The percentage error of the calculation is zero. Conclusion The relative molecular mass of substance Z can be correctly identified by knowing the amount of hydrochloric acid that reacted with a known amount of Substance Z. Substance Z is sodium carbonate with a calculated relative molecular mass of 105. 99g.

An Analysis Of heart Of Darkness :: essays research papers

An Analysis of "Heart of Darkness" Joseph Conrad, in his long-short story, "Heart of Darkness," tells the tale of two mens' realization of the hidden, dark, evil side of themselves. Marlow, the "second" narrator of the framed narrative, embarked upon a spiritual adventure on which he witnessed firsthand the wicked potential in everyone. On his journey into the dark, forbidden Congo, the "heart of darkness," so to speak, Marlow encountered Kurtz, a "remarkable man" and "universal genius," who had made himself a god in the eyes of the natives over whom he had an imperceptible power. These two men were, in a sense, images of each other: Marlow was what Kurtz may have been, and Kurtz was what Marlow may have become. Like a jewel, "Heart of Darkness" has many facets. From one view it is an exposure of Belgian methods in the Congo, which at least for a good part of the way sticks closely to Conrad's own experience. Typically, however, the adventure is related to a larger view of human affairs. Marlow told the story one evening on a yacht in the Thames estuary as darkness fell, reminding his audience that exploitation of one group by another was not new in history. They were anchored in the river, where ships went out to darkest Africa. Yet, as lately as Roman times, London's own river led, like the Congo, into a barbarous hinterland where the Romans went to make their profits. Soon darkness fell over London, while the ships that bore "civilization" to remote parts appeared out of the dark, carrying darkness with them, different only in kind to the darkness they encounter. These thoughts and feelings were merely part of the tale, for Conrad had a more personal story to tell, about a single man who went so far from civilization that its restraints no longer mattered to him. Exposed to the unfamiliar emotional and physical demands of the African wilderness, free to do exactly as he chose, Kurtz plunged into horrible orgies of which human sacrifice and cannibalism seemed to have formed a part. These excesses taught him and Marlow what human nature was actually like: "The horror!" Kurtz gasped before he died. Marlow's own journey from Belgium to the Congo and thence up the river then took on the aspect of a man's journey into his own inner depths. Marlow was saved from the other man's fate not by higher principles or a better disposition, but merely because he happened to be very busy, and the demands of work were themselves a discipline. The readers perceive, too, that other white

Pro Death Penalty – Essay

One main person involved was Susan Atkins an intelligent woman twisted by the ideas of Manson. She stabbed Sharon Tate, a pregnant actress, sixteen times, Sharon begged for mercy and Susan Atkins told her â€Å"there would be no compassion for her or her unborn bar, and after tasting the victim's blood she used the blood to write the word â€Å"pig† on the front door and left. After she admitted to stabbing the pregnant actress in her 1971 court trial, she was sentenced to the death penalty. BUT due to the Supreme Court decision in 1972 of abolishing the death penalty, Atkins was now In prison for life with POSSIBLE PAROLE!She Is now on the brink of death and has cost the state of California over 1. 4 million dollars alone in medical costs That's doesn't even include the 3. 5 million dollars it has took to care for her in prison for almost forty years! In total, this adds up to 5 million dollars The cost to keep the death penalty in California Is ninety million dollars. Right now California has 3,300 people in for a life sentence, this only adds up to the seventy five million dollars right now. But riddle me this with crime rates only moving up in these financially bad times do you want to run the risk of putting more in life in Jail? The costs here say.If we add one hundred people a year to the life In prison list It will only take seven years for the price of life penalties to be higher than the death penalty price! Now some people believe that sometimes the person that was accused didn't even commit the crime and that that person is being killed for no reason, but with modern technology today there Is a very unlikely chance of mixing a person up with the convict. One of the easiest ways to find out If the defendant Is the killer Is by using DNA testing to see if their DNA matches the convicted person, also besides DNA routs can use finger prints to identify the killer.Now even the person convicted isn't the killer there has been in the last few years a average waiting time on death row of 12 and 1/2 years with some men walling up to 25 years, that give the defendant and the government more than enough time to review the case and look for new evidence!!! But enough with costs of the death penalty, what is your moral view. People view the death penalty in many ways, some for it and others against it. But what It takes for ones opinion to be changed Is the death of someone you know or are Emily members with. Most seek revenge and want that person to die and experience what they did to the victim.Now what would you want a the killer of you dad or you mom, maybe you sister or brother to get? Life in prison or the death penalty. The murderer should have to face what their victim did! Now what do you really want? During life prison the prisoners can get a chance to have a education In prisons While we are paying for college and schooling they are getting a free education that 1 OFF we pa Rebuttal The plan proposed by the affirmative s ide will not work! While we are paying for allege and schooling prisoners can be getting a free education that we pay for with our tax!For the people locked up for life in prison. It's a university of crime where prisoners are schooled to be â€Å"better† criminals. The taxpayers pay the tuition. It costs more than a Harvard education. Prison is the breeding ground for the worst social evils. Remember that 35 out of the 50 states still support capital punishment! That is more than 70% of the states, that dost even include the U. S. Government that also supports capital punishment. Ohio also uses the death penalty. Also more than 62% f Americans still support the death penalty. That is way more than half!It also comes down to the view of the watcher, some people that don't support the death penalty haven't gotten to feel what it is like to have a brother or parent, child or friend killed. Many peoples view change when they are asked, † If someone you loved was murdered, would you still want them to have life in prison or do them deserve what they did? â€Å". Many people are hit hard by this question, but what would you want? To know that the murderer that killed a loved one gets the same thing that they did to the victim? Or to see them in prison possibly getting an education with our tax money!With DNA testing and the new advancements in forensics there is almost no chance that the accused is really not the killer. Some killers out there have killed seven people or more, and you really want them to get away with it? Than this is not the America our founding father based it on! People deserve the right to know that they don't have to go to bed worrying that the murderer that killed there loved one is out there not getting what they deserve! Just like in the courts of King Hamburg, The convicted deserves the eye for an eye tooth for a tooth treatment.The idea of abolishing the death penalty is corrupt and will ruin the system, many say that the de ath penalty cost more than life in prison, but if all the people on death row are put in for life in prison within 10 years the death penalty cost will look tiny compared to the price of life in prison. .Sam and Andrew are wrong! If we let people like them take control of society who knows? Maybe gay marriage will be legalized and a women can go and abort a baby, as if it is Just a regular part of their daily routine! Getting rid of the death penalty will ruin society!

Behaviorism And The First American Psychological Revolution

Behaviorism Behaviorism has been a topic of many controversies in the early stages of developing. This paper will present a synthesis of several articles discussing behaviorisms and its development through various schools of theories, in addition known researchers and conclusions. The first article that illustrates behaviorism is, â€Å"Behaviorism at 100† by Ledoux (2012), which details the last 50 years of the study of behaviorism. The next article is â€Å"Behaviorism† by Moore (2011), maps the beginning of behaviorism with B.F.Skinner and addressing functionalism and structuralism. The article named â€Å"Psychology as the behaviorist views it†, written by Watson (1913) put his emphasis the aspects of psychology and how behaviorist view introspection. Green (2009) article â€Å"Darwinian Theory functionalism and the First American psychological revolution†, is very adamant to have is readers to know that functionalism was the foundation that behaviori sm was built. Clark (2004) article â€Å"The classical origins of Pavlov’s conditioning†, give insight into classical conditioning abroad and in the United States. The last article named â€Å"Little Albert’s alleged neurological impairment† written by Digdon , Powell and Harris (2014), focus on ethical concerns and that may have been overlooked. The synthesis paper will provide behaviorism and conclusions that can draw overall messages from the articles mentioned above.
