Solubility Curves

Water Chemical formula- H2O State at room temperature- Liquid Colour- Clear Melting point- 0oC Boiling point- 100oC Water- good solvent and a range of substances will dissolve in it. What happens when a sugar lump dissolves in water? When the sugar dissolves†¦ -The moving water molecules crash into the sugar particles -The sugar particles then break away from the crystal and into the water -The sugar and water particles then mix and diffuse evenly throughout.Copper sulphate- blue crystals, hydrated because they have water trapped within them. When they are heated this water evaporates, the crystals become dehydrated and turn white. Equation for this Reaction. CuSo4 5H2O —> CuSo4 + 5H2O Solute- Solid which is dissolving Solvent- liquid in which the solute dissolves Solution- the solute and solvent mixed together Sodium hydroxide- Soluble Copper Oxide- insoluble Calcium hydroxide- Insoluble Silver iodide- insoluble Aluminium nitrate- solubleMost ionic substances will dissol ve in water but covalent substances usually wont dissolve. Solubility of a solute = mass of a solid required to a saturate 100g of water at a particular temperature. Calculating Solubility 2g potassium chlorate dissolves in 20g water at 28oC what is its solubility? 2 x 100/20 = 10. 0g potassium chlorate/100g water 4g potassium sulphate dissloves in 30g water at 50oC what is its solubilty? 4 x 100/30 = 13. 33g potassium sulphate/100g water 0g sodium chloride dissolves in 75g water at 10oC what is its solubility? 30 x 100/75 = 40g sodium chloride/100g water Solubility Of Gases Carbon dioxide is the gas which is dissolved in fizzy drinks to make the fizz. What happened when you placed sprite in a boiling tube and gave it a shake? The sprite fizzed up. What happened after you heated the sprite then gave it a shake again? If fizzed just a little Carbon dioxide is more soluble in cold liquid. The solubility of gases decreases as the temperature increases.

Bugs Emotions essays

Bugs Emotions essays Recently in class, we did a study on potato bugs, and how you can tell if they have emotions. I was gone the two days that we did the lab, so I am writing you a small report about my idea about bugs and their emotions. At first, when you think about it, most people would shrug unknowingly and reply, I dont know, or some people just automatically think that they have no emotions. It is a hard question, something that you just cant figure out by thinking. It is something that you have to research, and maybe even do a test on a bug, and see what happens. I have an example that will help my conclusion to the question that was asked. My dad has a fish tank with four small frogs inside. Everyday, he puts some small crickets into the tank for the frogs to eat. Weve sat there next to the tank and watched them eat the crickets, and this is how I figured out that bugs do have emotions. Not every kind of emotion, but simply instinct, which I would consider a type of emotion. You can tell this because when the frogs would be hungry and begin to prey on the crickets, the crickets would respond by standing completely still, or running away. They sense that something is going to happen, so they do the best that they can to stop that from happening. An instinct is something that any form of life has when they are born, Its something thats there, and you might not notice it sometimes. It can be a form of an emotion because you dont really notice your emotions that are there until you need to use them, just like your instinct. You use your instinct when you know that something is wrong or you need help. Your emotions really dont show either until you need to use one of them, say when your upset, then your emotions come out. The way that the crickets acted when the frogs were coming to eat them...they were acting like they knew that something was going to happen to ...

DreiserS Sister Carrie Essays - Carrie, English-language Films

DreiserS Sister Carrie Essays - Carrie, English-language Films DreiserS Sister Carrie I think it is very difficult to define the exact character of Dreisers Sister Carrie, and his original intention. I would say, as many eyes, so many opinions, so no wonder there are different approaches and interpretations towards the novel which is influenced not just by the readers reading or personal experience, but also by their particular philosophy of life as well as knowledge about the historical background. Sister Carrie can be read as a novel of desire, seduction, or the critique of capitalism and consumerism. Its definitely not the plot or characters which are dominant elements of it. The taste and the literary value of Dreisers novel is shaped and created by its setting and the authors tone. Chicago and New York have almost as organic and important role in the novel as the characters. They do not just form the simple environment for the novel, but they influence its character and a very strong impression. Chicagos character is kind of more positive, it is a city of promise, luck, rise (Carrie). We can say that in Chicago, Hurtswood means something. New York s character is different. Its a city of lies, fall, impersonal isolation of walled city where surviving is much more difficult than in Chicago. In New York, Hurstwood means nothing. The setting creates different expectations to people. During the reading of Sister Carrie, I was interested in searching and revealing the different kinds of desire. Generally we can say that Dreiser deals with the desire of wealth, social status, material things which are represented by money. Within this generalization, we can find and identify many other faces and forms of lust and longing. Carrie, as an ambitious and strong woman embodies the social values of the consumer culture. All she longs for is a material wealth, which represents power. She can be seen as a symbol of money. But Carrie lives in a world of prices. Her labor costs $4.50; board $4 a week; car fare $.60; cheap lunch $.10; etc. She imitates everything perfectly and thats why she is becoming what people want her to become. Her desires come from other peoples desires. It is exactly Drouet, who introduces her to the world of wealth, to materialism. He gives her money, flat even name when she enters the world of theater. She plays her role according to Drouets desires once acts as his mistress or wife. She plays a kind of role for him and by imitating whatever the drummer desire s in women, she becomes merely a reflection of masculine desire. It seems to me that she is never allowed to express any desire of her own except for her desire for consumption (admiring and buying clothes). I think in her relationship with other people, she feels bigger pleasure fro being desired than for feeling desire of her own. The question is wheter Dreisers attitude towards women is negative or positive? Are his women just objects or active characters? Or does Dreiser reinforce the conventional belief that the essence of a woman is just a performance of a role? I think we can also talk about a kind of prostitution as for the female characters, namely Carrie and Julia. Carrie sells herself for $20, and she is paid far more for her body than she is for her labor. Julia also demands money which makes her marriage also as a form of prostitution. Is sex in this world, consumption society, a womans most marketable product? Do these women have or even can they have their own faces? Hurstwoods desire is to possess, to possess a quiet and peaceful life with exciting episodes. He views marriage as a contract that gives him a right to control both women without questions. He thinks he has the absolute power to make decisions. Does Dreiser want to stress that power is a natural and singular masculine right? Dreisers attitude towards his characters is pretty confusing. He tries to manipulate his readers and throughout the novel, he makes comments judgements on the characters and their actions. Definitely, he feels more sympathy towards his male characters. His opinion on women is not pleasant, he is putting them to a position of creatures who are naturally imitative,

A Definition of Liberal Media Bias

A Definition of Liberal Media Bias A  Gallup poll found that just 40% of Americans trust the media to fairly and accurately report the news. Much of this has to do with the liberal tilt of news coverage and stories. In politics, conservatives often deal with an overwhelming liberal bias within the mainstream media, which includes the news divisions of major broadcast networks and major newspapers. This is typically just referred to as media bias. Media bias does not refer to the political punditry class as political affiliations are usually known and the commentary is intended as opinion-oriented. Media bias does not refer to media figures such as Rachel Maddow, Bill OReilly, and Al Sharpton who are expected to give political viewpoints. What Is Media Bias?   Media bias refers to the allegedly objective journalists in print and media who intentionally - and sometimes unintentionally - report or cover stories in a way favorable to Democrats and liberals and unfavorable to Republicans and conservatives. Journalists such as Dan Rather, Bob Schieffer, and Wolf Blitzer who portray themselves as pure newsmen could have their biases exposed by delivering one-sided news stories. Dan Rathers attempted takedown of George W. Bush comes to mind. Examples of Media Bias Barack Obama received free passes in both the 2008 and 2012 presidential races as the media was primarily interested in highlighting the historic nature of Obamas campaign. While Sarah Palin was heavily criticized by the media as lacking the experience to be Vice-President, the question was never a major issue with the decidedly less-experienced Obama. In 2012, the media turned every statement by Mitt Romney (dogs on vacation!) into stories that lasted weeks, while at the same time refusing to cover the Fast and Furious scandal or the Benghazi attacks with seriousness. And CNNs Candy Crowley infamously interrupted a debate exchange between Romney and Obama by debating Romney herself on Benghazi. (She was wrong, but the ramifications were huge.) While VP Joe Biden could barely take the stage without making a hysterical gaffe during his tenure, his sanity or competence was never questioned in the way that Dan Quayles was for once adding an e at the end of potato during a spelling bee. That the card was given to Quayle by the school with the incorrect spelling and that Quayle had questioned the spelling on the card is the part of the story the media always enjoys ignoring. While Democrats regularly get softball question and answer sessions from serious journalists, conservatives are usually left answering absurd questions based on absurd assumptions. When a deranged gunman shot Congresswoman Gabby Giffords of Arizona, the media had absolutely no problem claiming Sarah Palin was to blame because she once had a map on her website that had used a target on it to imply that it was going to be a competitive congressional race. Unbiased, Fair and Objective   The problem with media bias is that the journalist and media personalities are claiming to be unbiased, fair, and objective but typically end up delivering one-sided viewpoints disguised as fact. Many Americans will not look deeper into every issue presented by the media, instead of taking the stories at face value. Any information that might dispel the media bias myths has to be actively sought. Pronunciation: me-di-a bÄ «Ã‰â„¢s Also Known As: Mainstream Media; Lamestream media (Sarah Palin); Dinosaur Media (Laura Ingraham) Alternate Spellings: none Common Misspellings: none Examples In a free country, people depend on the media for their information about government and other powerful institutions. If the press sounds the alarm about some danger, people have to pay attention. But if they have lost confidence in the press – because of its biases – then there’s a good chance we’ll ignore the warning. And that could be dangerous. - Bernard Goldberg on Media Bias 60 Minutes used to be synonymous with gotcha, and it certainly was when it broke the Abu Ghraib story to hurt Bush in 2004, and when Dan Rather flaunted fake Texas Air National Guard documents to hurt Bush months later. In the 2008 election cycle, â€Å"60 Minutes† asked John McCain why he would let the Wall Street executives sail away on their yachts and leave this [bailout] on the American taxpayer? They hammered Romney about avoiding military service – and his five sons avoiding military service. Kroft has never asked Obama about his failure to serve in the military, and he certainly never asked about whether he had premarital sex with his wife – which Mike Wallace threw at Romney. - Brent Bozell

Conceptual Issues in Evolutionary Archaeology Research Paper

Conceptual Issues in Evolutionary Archaeology - Research Paper Example Jones is mainly recognized because of the many films he has acted, some of which include: Last crusade, Lost Ark Raiders and Temple of Doom among others (Winterhalder & Eric, 2000). In understanding the character of Indiana Jones, these films depict some of the traits that make him have a great influence over the people. Most of these films have similar plots, presenting the ways which Indy employs to prevent Hitler’s hands from holding the biblical artifacts. For instance, the movie that explains how the covenant ark was lost is a controversial story, by first trying to understand if the ark existed in the first place. Scholars have ever since tried to explain the whereabouts of the ark, but they have not yet come up with valuable conclusions to the issue (Bentley & Herbert, 2001). Some say it was carried to Canaan while others say that it was destroyed in Babylon.Another movie that approaches archeology in a better way is Last Crusade. It similarly explores another treasure in the bible- Holy Grail (Arnold & Nancy, 2001). This treasure like the ark has numerous stories surrounding its history. People have no clear idea of its existence, and where it finally went to. Some people claim that Arimathea Joseph carried the Grail to France with him, and this claims triggered Nazi to start his Grail search. In the movie, Jones acts brilliantly during their travel, by making marks on the way which in turn give him clues that guide him to the final resting place of the Grail.... His theoretical diversity in many of the movies he has acted, portray him as a real archeologist from the way he dresses to the way he presents himself. Processual archaeology presents three perspectives that we can employ in studying Indiana Jones: evolutionary ecology which predicts human behaviors in their ecological contexts, and evaluates their behaviors using ethnographic and archaeological data. Secondly, there is behavioral archaeology which focuses on when, where and how human behavior relates to material cultures. Arnold & Nancy (2001) explain that there is the Darwinian archaeology perspective that tries to reconcile Darwinian Theory and other scientific explanations of evolution. On the other hand, the postprocessual perspective comes up with criticisms of the early studies. Literature Review Postprocessual Archeology Postprocessualists are opposed to the ideas of science as the only source of knowledge. They generally classify scientific studies into non-positivist perce ptions with no basis (Johnson, 2010). For instance, these people claim that the empirical studies done by science are not satisfactory enough, since they do not have sufficient fundamental facts. According to the postprocessualists, we have active individuals hence, they do not agree with the views of archeologists who make individuals to be lost in their theories. They thus advocate for individuals to be active instead of following blindly the social norms and values that are presented to them. They then emphasize on agency as a tool of active individuals (Hegmon, 2003 & Hurt & Rakita, 2001). Focusing on their understanding, one can conclude that they urge archaeologists to consider rules that can be changed creatively by social

How Far Garlands Theories Can Be Applied in the Contemporary Criminal Research Paper

How Far Garlands Theories Can Be Applied in the Contemporary Criminal Context - Research Paper Example The objective of the paper is to assess how far Garland’s theories can be applied in the contemporary criminal context, specifically in sentencing. At the outset, the essay will describe the two responses, i.e, adaptation and denial, proposed by Garland. Two newspaper articles dealing with Government reforms on sentencing guidelines will be assessed to determine whether they are examples of adaptation or denial. Contextual factors that lead to such a response will also be analyzed so that the extent of applicability of Garland’s views can be determined. According to Garland, in earlier years, the criminal justice system had assumed a hybrid penal welfare structure, combining due process and proportionate punishment with a decisive thrust in the correctional direction, favoring rehabilitation, welfare and criminological expertise. (Garland, 2001: 27). Developments in correctional policies demonstrated a commitment to community-based solutions, with a focus on the rehabilitation of offenders and the tailoring of individual penal sentences framed in accordance with the characteristics and needs of the offenders. This approach exemplifies a pragmatic and adaptive Government response to crime, characterized by (a) the State role as a facilitator rather than controller of criminal policy (b) focus on the consequences rather than causes of crime (c) participation of non-State actors in prevention of crime (d) viewing crime prospectively, i.e, institution of crime prevention measures (Garland, 1996).
