Data observation Essay Example for Free

Data observation Essay Complete a data table that includes a prediction of reaction type (single replacement, double replacement, synthesis, decomposition, or combustion), observations, and identification of reaction type for each reaction in the lab. (10 points) Reactants Prediction of Reaction Type Observations Reaction Type Iron (III) and copper (II) sulfate solution single replacement Solids stay concentrated at the bottom Single replacement Lead (II) nitrate and potassium iodide solutions Double replacement Yellow colored powder collected at the bottom Double replacement Magnesium metal and hydrochloric acid solution Single replacement The solution began to fizz. Proves to be flammable. single replacement Electrolysis of water decomposition The water bubbles In the tubes filled with H2 and O2 decomposition Burning magnesium combustion As the magnesium comes in contact with the CO2 it creates a bright burning light synthesis Conclusion: Write a balanced equation for each reaction observed in this lab. (10 points) 2Fe + 3CuSO4 = 3Cu + Fe2(SO4)3 Pb(NO3)2 + 2KI = PbI2 + 2K(NO3) Mg + 2HCl = MgCl2 + H2 2H2O = 2H2 + O2 2Mg + O2 = 2MgO If you were to measure the mass of magnesium and hydrochloric acid before combining them in the test tube, how would that mass compare to the mass of reactants left in the test tube after the reaction? Explain your answer and how it corresponds to the law of conservation of mass. (5 points) -The mass would be the same as it started. This is because the law of conservation of mass states that energy cannot be created nor destroyed only changed. One of the reactions you conducted can actually be categorized as TWO different types of reactions. Which reaction is this, and what are the two types of reactions? (5 points) It would be the Magnesium metal and hydrochloric acid solution because it bubbled but it still stayed in its form and didn’t change. It is single replacement or combustion.

Antigone Essay :: essays research papers fc

All true Greek tragedies were written using the same basic set of characteristics. One such characteristic was that all the characters were of nobility. This was to ensure that their fall from grace would be greater to those watching the play in action. Another characteristic of all Greek tragedies is that they were written in poetic form, as this was the style of writing at the time. There were also always almost constant references to the gods and to matters of fate. And it was the ever-present chorus who made a great deal of these references. One of the most important characteristics of the Greek tragedy was that the hero of the play always had a fatal flaw which proved not only to be their downfall but the cause of destruction of all those around them. Sophocles play â€Å"Antigone† is a wonderful example of the Greek tragedy because it encompasses all these characteristics.   Ã‚  Ã‚  Ã‚  Ã‚  The major characters in the play are all nobility in some form or another. Antigone is the daughter of Oedipus and Iocaste the former king and queen which makes her a princess (Scene 2, Lines 1-2) (Scene 4, Lines 36-44). She is also the sister of Ismene (Prologue, Lines 1&7) which makes her a princess as well. The ruling king of Thebes at the time is King Creon (Prologue, Line 6). He has a wife Eurydice who is queen (Exodus, Line 25-26) and a son Haimon who is the prince (Exodus, Lines 64-68). The reason that the characters were all forms of nobility is to make their fall from grace and or powers seem even greater and harder for them to bear. This was designed to be uplifting to the common peoples of ancient Greece.   Ã‚  Ã‚  Ã‚  Ã‚  Like other play that were written at this point in time Sophocles wrote his play â€Å"Antigone† in poetic form. This can be seen in various places throughout the play (Parados, Line 1-7). And although some of its poetic form is lost in the translation of the play from ancient Greek to Modern English, it is still evident primarily when the chorus is explaining the passage of time (Scene 4, Lines 33-36). Or describing a battle to the audience (Parados, Lines 34-38).   Ã‚  Ã‚  Ã‚  Ã‚  Antigone is also full of references to the gods and to fate (Exodus, Lines 3-6) and how it has affected specific character’s lives. The chorus made a large amount of these references themselves, when talking about the gods (Ode 2, Lines 13-18) and to fate (Ode 2, Lines 25-28).

Injuries in the Nfl

National Football League Injury Controversy In America sports are important but football seems to be vastly more important and more widely known as a specifically American sport. The overwhelming topic on any sports network such as ESPN and the NFL Network are the growing number of lawsuits against the National Football League concerning head injuries and lack of concern that the leaders of the NFL had about the risk players were being put in.Both sides of the lawsuits are passionate about their ideas and making sure that they are not only heard but that action will take place to resolve the situation as a whole. George Orwell states that â€Å"one can choose – not simply accept – the phrases that will best cover the meaning, and then switch around and decide what impression one’s words are likely to make on another person†. (115) The power of words can make or break an argument; the words surrounding the NFL Controversy are no different inevitable, perman ent and intentionally misleading players putting them at serious health risk.Inevitability is the strongest stance that the leaders on the National Football League have against the concussion controversy. Football is one of the most barbaric, brutal sports played in America it is a high contact sport that is known for the big hits during crucial moments in a game. Because of the nature of the game there has always been protective equipment that the players are required to wear, one of the most important being the helmet.Players are signing contracts with various teams knowing that they are involved in a contact sport and that there is a guarantee that they will be hit. (Rovell) There is no way to stop a player from the opposing team that is running at their full speed to just stop on a dime and not make contact with a player, it simply goes against physics. Rules have recently been put in place fining players for helmet to helmet contact but you cannot knock out the contact entirely without changing the dynamics of the entire game.The NFL choses to use the word inevitable to describe there is not a clear answer to stop contact all together, the players know how the game is played and what risks are involved, thus proving that the players must have had prior knowledge to the issue and the potential risk to serious injury. The entire controversy began as more and more ex-players were being diagnosed with permanent debilitating neurological disorders. (Anderson) The NFL says this is typical udging by the age range and the regression of the brain as we age, but now there are ex-players in their late 50s and early 60s being diagnosed which is out of character. So it is more or less being swept under the rug as something that is human nature and out of their hands. Most neurological problems can be treated and progression is slowed but the issues are ultimately incurable. Getting a diagnosis of a permanent injury is unimaginable. To most it would be seen as a form o f a death sentence, just biding your time before the disorder takes over and your life is cut short.Psychologically one would begin to question the life they have lived and attempt to adjust to your new normal because the fact is simply there is no going back. Ex-players and family members are using the word permanence to push the feeling of the final stage, and to realize that you’re at your peak and there is nowhere but down. Using this particular word in this context brings up a morbid feeling of looming illness and finally death do to the carelessness of the NFL.The main point in the case against the National Football League is that they intentionally mislead players and put them at a serious health risk later on in life, by not having the players properly evaluated after suffering from a head injury. Treatments were not regulated and initial baseline testing was being cheated by players so if they did suffer a head injury they would have a larger margin of error and coul d continue playing. Coaches needed star players so a debilitating injury like a concussion that has a long recovery time was not an option.Owners and coaches knew sitting a player for weeks on injury reserve would most likely cost them the season and in some cases their jobs and lively hoods so reports would be scrubbed and false information would be recorded to insure the player would return the following week. Using the phrase intentionally misleading players leads one to believe there was prior knowledge of possible serious complications with repeated blows to the head that went untreated.The power of words and make or break an argument just as it is in the NFL injury controversy. The use of words and phrases are â€Å"designed to make lies sound truthful and murder respectable, and to give an appearance of solidity to pure wind†. (Orwell,116) Language allows the audience to pick a side of the argument, align themselves and share the same ideas with one side or the other. Having the power to use these trigger words keeps an ongoing chain of support, they are words that are relatable something for an individual to grab onto and run with.If you are arguing a point you are trying to get someone on your side and to believe that you are saying so you want to appeal to their logic, emotion, and purpose in the most strait forward way which would be the use of language.

Analysis Of Sharon M. Drapers Copper Sun - 1144 Words

In the novel, Copper Sun, Sharon M. Draper quotes a fictional auctioneer: â€Å"Do I hear more than ten pounds for this fine example of African womanhood? Hardly a scratch on her. Bright enough to be taught simple commands, like ‘Come here’ and ‘Lie down’† (52). Amari, the terrified teenager the auctioneer was talking about, was recently taken from her home, chained, and crammed into a slave ship set for America. While on the slave ship, people underwent hunger, sickness, thirst, rape, and death. Though Sharon M. Draper wrote these characters as fictional, they correctly portray people that have lived during that time period. Because of this, Copper Sun is historically accurate and correctly depicts the story of an African girl, as well as the†¦show more content†¦According to FMM in an article titled Francisco Menendez, this was true because in the 1740’s, England attacked Fort Mose, but most of the citizens there were already moved t o the protection of St. Augustine. Sharon M. Draper was able to accurately depict the characters, while also giving them their own story. Although most of the characters in the novel are fictional, many of the places they go to are real. Towards the end of the story, Amari, Polly, and Tidbit escape the Derby’s and head for Fort Mose, a place in Florida where slaves can be freed, which in fact, is true. In an article by PBS, called Fort Mose, Fort Mose was a society of laborers and growers who integrated approaching fugitives, slaves, and Indians from nearby places into an involved family chain. Fort Mose was located two miles north of St. Augustine, and was controlled by the Spanish at the time (PBS). Another major setting in Copper Sun is the Derby Plantation. Though the plantation is not a real place, it resembles what a plantation was like back then. For instance, the hut Polly and Amari lived in was a single room with little outside light and made of rough wooden planks. Like the other huts, the floor was dirt, but other huts around them were made of mud and clay (Draper). SciWay supports Draper’s por trayal of the huts in their article, The Lives of African-American Slaves in Carolina During the
