Solute Definition and Examples in Chemistry

A solute is defined as the substance that is dissolved in a solution. For solutions of fluids, the solvent is present in greater amount than the solute. Concentration is a measurement of the amount of solute present in a chemical solution, with respect to the amount of solvent. Examples of Solutes Usually, a solute is a solid that is dissolved into a liquid. An everyday example of a solute is  salt in water. Salt is the solute that dissolves in water, the solvent, to form a saline solution. On the other hand, water vapor is considered a solute in air because nitrogen and oxygen are present in much larger concentration levels in the gas. Different Types of Solutes When two liquids are mixed to form a solution, the solute is the species present in the smaller ratio. For example, in a 1 M sulfuric acid solution, sulfuric acid is the solute while water is the solvent. The terms solute and solvent can also be applied to alloys and solid solutions. Carbon may be considered a solute in steel, for example.

The Setting for Williams A Streetcar Named Desire

The setting for A Streetcar Named Desire is a modest, two-room flat in New Orleans. This simple set is viewed by the various characters in sharply contrasting ways—ways that directly reflect the dynamics of the characters. This clash of views speaks to the heart of the plot of this popular play. An Overview of the Setting A Streetcar Named Desire, written by Tennessee Williams is set in the French Quarter of New Orleans. The year is 1947—the same year in which the play was written. All of the action of A Streetcar Named Desire takes place on the first floor of a two-bedroom apartment.The set is designed so that the audience can also see outside and observe characters on the street. Blanches View of New Orleans Theres a classic episode of The Simpsons in which Marge Simpson lands the role of Blanche DuBois in a musical version of A Streetcar Named Desire. During the opening number, the Springfield cast sings: New Orleans!Stinking, rotten, vomiting, vile!New Orleans!Putrid, brackish, maggoty, foul!New Orleans!Crummy, lousy, rancid, and rank! After the show aired, the Simpsons producers received a lot of complaints from Louisiana citizens. They were highly offended by the disparaging lyrics. Of course, the character of Blanche DuBois, the faded Southern belle without a dime, would completely agree with the cruel, satirical lyrics. To her, New Orleans, the setting of A Streetcar Named Desire,  represents the ugliness of reality. To Blanche, the crude people that live on the street called Elysian Fields represent the decline of civilized culture. Blanche, the tragic protagonist of Tennessee Williams play, grew up on a plantation called Belle Reve (a French phrase meaning beautiful dream). Throughout her childhood, Blanche was accustomed to gentility and wealth. As the estates wealth evaporated and her loved ones died off, Blanche held on to fantasies and delusions. Fantasies and delusions, however, are very difficult to cling to in the basic two-room apartment of her sister Stella, and specifically in the company of Stellas domineering and brutal husband, Stanley Kowalski. The Two-Room Flat A Streetcar Named Desire takes place two years after the end of World War II. The entire play is staged in the cramped flat in a particularly low-income area of the French Quarter. Stella, Blanches sister, has left her life at Belle Reve in exchange for the exciting, passionate (and sometimes violent) world that her husband Stanley has to offer. Stanley Kowalski thinks of his small apartment as his kingdom. During the day, he works in a factory. At night he enjoys bowling, playing poker with his buddies, or making love to Stella. He sees Blanche as an intruder to his environment. Blanche occupies the room adjacent to theirs—so close that it impinges on their privacy. Her garments are strewn about the furniture. She adorns lights with paper lanterns to soften their glare. She hopes to soften the light in order to look younger; she also hopes to create a sense of magic and charm within the apartment. However, Stanley does not want her fantasy world to encroach upon his domain. In the play, the tightly-squeezed setting is a key factor in the drama: It provides instant conflict. Art and Cultural Diversity in the French Quarter Williams offers multiple perspectives on the plays setting. In the plays beginning, two minor female characters are chatting. One woman is black, the other white. The ease with which they communicate demonstrates the casual acceptance of diversity in the French Quarter. Williams is presenting here a view of the neighborhood as having a thriving, exuberant atmosphere, one that nurtures an open-minded sense of community. In the low-income world of Stella and Stanley Kowalski, racial segregation appears to be nonexistent, a sharp contrast to the elitist realms of the old South (and Blanche Dubois childhood). As sympathetic, or pathetic, as Blanche may appear throughout the play, she often says intolerant remarks about class, sexuality (in the case of her homosexual husband who was devastated by her negative comments), and ethnicity. In fact, in an ironic moment of dignity (given his brutality in other contexts), Stanley insists that Blanche refer to him as an American (or at least Polish-American) rather than use the derogatory term: Polack. Blanches refined and disappeared world was one of brutal racism and denigration. The beautiful, refined world she longs for never existed. In the present as well, Blanche maintains this blindness. For all of Blanches preaching about poetry and art, she cannot see the beauty of the jazz and blues which permeate her present setting. She is trapped in a so-called refined, yet racist past and Williams, highlighting the contrast to that past, celebrates the uniquely American art form, the music of the blues. He uses it to provide transitions for many of the plays scenes. This music can be seen to represent the change and hope in the new world, but it goes unnoticed to Blanches ears. Belle Reves style of aristocracy has died away and its art and genteel customs are no longer relevant to Kowalskis post-war America. Gender Roles After World War II The war brought innumerable changes to American society. Millions of men traveled overseas to face the Axis powers, while millions of women joined the workforce and the war effort at home. Many women discovered for the first time their independence and tenacity. After the war, most of the men returned to their jobs. Most of the women, often reluctantly, returned to the roles as homemakers. The home itself became the site of a new clash. This post-war tension between the roles of the sexes is another, very subtle thread in the conflict in the play. Stanley wants to dominate his home in the same way males had dominated American society before the war. While the main female characters in Streetcar, Blanche and Stella, are not women who are seeking the socio-economic independence of the workplace, they are women who had money in their youth and, to that degree, were not subservient. This theme is most evident in Stanleys well-known quote from Scene 8: What do you think you are? A pair of queens? Now just remember what Huey Long said—that every mans a king—and Im the King around here, and dont you forget it. Contemporary audiences of Streetcar would have recognized, in Stanley, the male side of what was a new society-wide tension. The modest two-room flat that Blanche disdains is this working mans kingdom and he will rule. Stanleys exaggerated drive for domination indeed extends, at the end of the play, to the most extreme form of domination, rape.

To Encourage Healthy Eating, Higher Taxes Should Be...

To encourage healthy eating, higher taxes should be imposed on soft drinks and junk food. Do you agree or disagree. Nowadays is getting more and more important to stay fit and healthy. There are a lot of negotiations about how to prevent junk food market. One of many possible solutions could be to impose higher taxes on soft drinks and junk food, what could encourage healthy eating. Although, from first sight, it can look like a good solution, but in this essay I am going to prove, that high taxes is not the best way, event, in my opinion, junk food must be replaced by healthy and home-made food. Firs of all, in many countries the high cost of eating healthy food is often just an excuse for being overweight, especially by†¦show more content†¦Several research studies have found that junk food can affect the brain almost the same way as nicotine or heroin. People get addicted to eating out, but they do not have to eat out because it is cheaper. That is why, in my opinion, imposing higher taxes on junk food would not prevent consumption of fast food and, even more, encourage healthy eating. People should, firstly, began to look after themselves, for example, eat a wide variety of nutrient-rich foods, do not starve themselves, maintain a healthy body weight, learn how to cook healthily, when dining out avoid fast food restaurants, eat regular meals, eat enough calories, but do not over eat, drink more water and, I think, the most important thing is to start moving. As it was said â€Å"eat to live, do not live to eat† and use the money you have left over to enjoy your life away from the table. To sum up, it is obvious, that no matter what a person tries to do, there is no way to prevent a consumption of soft drinks and junk food. Fast food impacts people brain and get them addicted to it and imposing higher taxes is not a solution.

The scarlet ibis free essay sample

In the short story, â€Å"The Scarlet Ibis†, James Hurst uses nature imagery to symbolize the narrator’s mixed emotions, supporting the theme that selfish pride generally causes more harm than good. In the story the narrator doesn’t know whether to care or be proud of his brother, or to be ashamed and careless. He has befuddled emotions towards his brother and he just wants him to be normal. In the story, the narrator teaches Doodle how to walk. Not because he cares about Doodle, but because he is embarrassed of him. â€Å"They did not know that I did it for myself†, (pg434, L181-L184). He only helped Doodle for his own selfish reasons. The narrator didn’t want to be seen with a handicap brother, so he encouraged or forced Doodle to walk and act like a regular kid. So he didn’t help Doodle out of brotherly love but out of being egoistic and caring what people thought of him and his family. We will write a custom essay sample on The scarlet ibis or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page James Hurst use of the Scarlet Ibis is a representation or symbol of Doodle. Both are fragile and rare, but special and exotic as well. â€Å"Even death did not mar its grace, for it lay on the earth like a broken vase of flowers, and we stood around it, awed by its exotic beauty†,(pg439, L304-L306). The scarlet ibis just died right in front of the family after traveling so many miles from home. The scarlet ibis is similar to Doodle, they both were in a place that was not suitable for them, and both were pushed to their limit. The scarlet ibis foreshadows Doodle’s death in the story. Towards the end of the story, the narrator is disappointed in Doodle because they didn’t finish their intentions for the summer. . The narrator pushes Doodle to his limit, to his full extent, to make sure he becomes like the â€Å"regular kids†. He was so angry with Doodle that words couldn’t express his feelings; he was probably thinking about how people would think about him and his crippled brother. â€Å"The rain was coming , roaring through the pines, and the, like a bursting candle, a gum tree ahead of us shattered†¦Ã¢â‚¬ ¦ and in the moment before the rain arrived, I heard†¦Ã¢â‚¬ ¦.. ‘Don’t leave me’†, (pg. 441, (L366-L370). This storm represents the narrator’s mixed emotions toward his brother. He was so angry, and upset with Doodle, that it forces him to leave him behind. The narrator was so vexed with Doodle that he left him back at Old Woman Swamp in the storm. Just because their plans were not complete, that does not leave him any reason to leave Doodle, his brother, who has the same flesh and blood as him. â€Å"The knowledge that Doodle’s and my plans had come to naught†¦Ã¢â‚¬ ¦..that streak of cruelty within me awakened†¦Ã¢â‚¬ ¦soon I could hear his voice no more†, (pg. 441, L371-L375). Because he was so angry, he left running away, leaving him behind, where death rested upon Doodle. If he didn’t have such an intense cruelty in him, he would’ve gone back and helped Doodle. The narrator didn’t know what to do he was so confused, sometimes he felt hatred towards Doodle and sometimes he didn’t, he had unbalanced emotions. He cared about what people thought of him, that what caused him to pressure Doodle to do things and push him to his limit. The narrator was so inconsiderate which supports the theme that selfish pride generally causes more harm than good.

Financial resources and decisions management Essay

Financial resources and decisions management - Essay Example equity and debt, comes with their advantages and disadvantages. Several factors, such as statutory rules and requirements, terms and conditions imposed by the counter party and general economic conditions are analyzed before selecting one of the options. The downside of acquiring financing through issuance of equity is that the procedure is quite complicated as compared to acquiring funds by approaching any bank. In most cases, a loan is acquired from any bank or financial institution by filing an application for the sanctioning of the loan. The bank or any other financial institution, after evaluating the necessary details such as credit history, financial outlook for assessing the ability of the entity to repay the loans in future, and the purpose of the project for which the loan application was filed, sanctions the loan. Whereas in the case of raising finances through issuance of equity shares, the company has to fulfill several requirements such as issuing a predefined number of shares, issuing shares to the existing shareholder in proportion to their existing shares and appointing a financial advisor for conducting a due diligence of the entity’s operations. ... In contrast, in equity financing, the company has to wait for a considerable longer period of time for the funds to become available for their utilization. 1.2 The two modes of finance available to the company would be raising funds through issuance of equity or acquiring loan in the form of a mixture of a long term and short term debt. Let us assume that the total requirement of funding for Quality windows Ltd is for ? 100,000. As provided in the scenario, 40% of the funding requirement can be met through internally generated funds, whereas for the remaining 60% the company has to decide about the mode of funding. Thus the amount of fund required to issue is ? 60,000. Option 1: Raising the fund through the issuance of shares The company decides to issue 6,000 shares at ? 12 (par value is ? 10 and premium is ? 2). As per the current market knowledge, the issuance cost per share is ? 1. Other administrative cost pertaining to the issuance of share is ? 5,000 in total which relates to publishing prospectus and appointing an under-writing agent. Thus the total cash inflows to the company for the first financial year would be as under: Particulars Amount in ? Shares issued 72,000 Issuance cost (6,000) Other costs (5,000) Total inflow 61,000 Option 1: Acquiring loan from a financial institution The company decides to acquire loan from a financial institution amounting to ? 70,000. The principal repayment will start two years from the end of the current financial year. In return, the financial institution will charge interest rate at the rate of 12%. Thus, following is the net cash inflow at the end of the financial year: Particulars Amount in ? Loan acquired 70,000 Interest cost (8,400) Total inflow 61,600 Thus it is apparent from the above analysis, that acquiring
