Why Is Water a Polar Molecule

Water is a polar molecule and also acts as a polar solvent. When a chemical species is said to be polar, this means that the positive and negative electrical charges are unevenly distributed. The positive charge comes from the atomic nucleus, while the electrons supply the negative charge. Its the movement of electrons that determines polarity. Heres how it works for water. Polarity of a Water Molecule Water (H2O) is polar because of the bent shape of the molecule. The shape means most of the negative charge from the oxygen on side of the molecule and the positive charge of the hydrogen atoms is on the other side of the molecule. This is an example of polar covalent chemical bonding. When solutes are added to water, they may be affected by the charge distribution. The reason the shape of the molecule isnt linear and nonpolar (e.g., like CO2) is because of  the difference in electronegativity between hydrogen and oxygen. The electronegativity value of hydrogen is 2.1, while the electronegativity of oxygen is 3.5. The smaller the difference between electronegativity values, the more likely atoms will form a covalent bond. A large difference between electronegativity values is seen with ionic bonds. Hydrogen and oxygen are both acting as nonmetals under ordinary conditions, but oxygen is quite a bit more electronegative than hydrogen, so the two atoms form a covalent chemical bond, but its polar. The highly electronegative oxygen atom attracts electrons or negative charge to it, making the region around the oxygen more negative than the areas around the two hydrogen atoms.  The electrically positive portions of the molecule (the hydrogen atoms) are flexed away from the two filled orbitals of the oxygen. Basically, both hydrogen atoms are attracted to the same side of the oxygen atom, but they are as far apart from each other as they can be because the hydrogen atoms both carry a positive charge. The bent conformation is a balance between attraction and repulsion. Remember that even though the covalent bond between each hydrogen and oxygen in water is polar, a water molecule is an electrically neutral molecule overall. Each water molecule has 10 protons and 10 electrons, for a net charge of 0. Why Water Is a Polar Solvent The shape of each water molecule influences the way it interacts with other water molecules and with other substances. Water acts as a polar solvent because it can be attracted to either the positive or negative electrical charge on a solute. The slight negative charge near the oxygen atom attracts nearby hydrogen atoms from water or positive-charged regions of other molecules. The slightly positive hydrogen side of each water molecule attracts other oxygen atoms and negatively-charged regions of other molecules. The hydrogen bond between the hydrogen of one water molecule and oxygen of another holds water together and gives it interesting properties, yet hydrogen bonds are not as strong as covalent bonds. While the water molecules are attracted to each other via hydrogen bonding, about 20% of them are free at any given time to interact with other chemical species. This interaction is called hydration or dissolving.

Child Labor Essay - 809 Words

Child labor has been an extremely serious issue since the early industrial revolution and it continues to be an issue today. The movement towards the industrial revolution increased demand for labor, especially cheap labor, which targeted young children as a means for performing work in the factories. Since it was an economically growing era for the United States, children in the 18th century worked long hours for low minimum wage under harsh conditions to help their families. Children were easily suitable for the working conditions in the factory because of their size, and it was easy to manage them because the factories did not have to worry about paying them more as compared to adults. Further, today in the United States of America,†¦show more content†¦The act has separate rules for children working in agriculture and in non-agriculture employment. For example, the minimum age for work in non-agricultural jobs is â€Å"18 years for hazardous occupations, 16 years for em ployment in non-hazardous occupations, and 14 years for a limited set of occupations, with restrictions on hours and work conditions† (Donovan, Shimabukuro, 2016). Further, there are several exclusions to the minimum age for work in agricultural jobs such as â€Å"16 years for employment in any agricultural job, including hazardous agricultural occupations, with no restrictions on hours of work, 14 years for employment in non-hazardous agricultural jobs outside of school hours, and any age for employment in non-hazardous agricultural jobs, outside of school hours, with parental consent, when certain conditions are met concerning farm size, the nature and duration of work, and other requirements† (Donovan, Shimabukuro, 2016). Even though the labor laws have extensively eradicated child labor in the US, it nevertheless poses concerns in the agriculture area of the economy today. Further, complex and different child labor laws for agriculture workers and non-agriculture workers increases the chances of violations of the labor laws.

To what extent and in what ways is Fitzgerald purely critical of Gatsby’s dreams Free Essays

One of the main themes of ‘The Great Gatsby’ is that of dreams, none of which is more noticeable than Gatsby’s own dream of five years in his pursuit of Daisy. What is less obvious is how Fitzgerald wants us to react to these dreams, and whether he is being purely critical of them or whether he in fact does also reveal some good in them. In this essay I aim to show that although in a lot of ways Fitzgerald is critical of Gatsby’s dreams, for example by ensuring that Daisy can never live up to the vision of herself which Gatsby has created, he is not entirely disapproving and in several cases even goes as far as to suggest that dreaming is what makes us human. We will write a custom essay sample on To what extent and in what ways is Fitzgerald purely critical of Gatsby’s dreams? or any similar topic only for you Order Now One way in which we may be unsure about Fitzgerald’s presentation of Gatsby’s dreams is whether they are meant to appear romantic or slightly pathetic. At face value it can seem to be extremely romantic that Gatsby has waited these five years and remained so loyal to Daisy, and I think that it this way Fitzgerald wants us to be on Gatsby’s side. Gatsby himself is portrayed as being a very romantic character and this can be seen in his speech when he talks about the past, for example telling Nick that â€Å"His heart beat faster as Daisy’s white face came up to his own. He knew that when he kissed this girl, and forever wed his unutterable visions to her perishable breath, his mind would never romp again like the mind of God†. Fitzgerald clearly is making Gatsby appear to be very wistful and dreamlike, and also is making us more sympathetic to him by making his affair with Daisy and his dreams appear to be very romantic. This would obviously cause the reader to sympathise more with Gatsby later in the book when everything falls apart, and I think that it is clearly true that Gatsby believes that his love of Daisy is very perfect and beautiful. However, this quotation could also be read that Gatsby is going too over the top and is trapped in the past by his dreams. Another good place to see this occurring is when Nick warns Gatsby that he cannot recreate the past and Gatsby replies with â€Å"‘Can’t repeat the past? Why of course you can! ‘†. This seems like a very irrational thing for Gatsby to say and it begins us questioning what he really wants from his dreams, whether it is Daisy or just to have the past back as it was. Fitzgerald may be doing this to show Gatsby as a man who is just clutching at a past he no longer has and this may make him appear slightly pathetic. The exclamation mark gives him a sense of panic and questioning makes him appear to be almost incredulous to any other way of seeing the situation, which I think is more critical of Gatsby’s dreams as they have blinded him to reality. Overall however, when it comes to romanticism or a slightly pathetic appearance, Fitzgerald remains quite ambiguous and leaves it more up to the reader to reach a decision by themselves. , Whichever way it is viewed however, I think in both situations we still have sympathy for Gatsby when his reality doesn’t quite live up to the vision. When Fitzgerald comments that â€Å"no amount of fire or freshness can challenge what a man can store up in his ghostly heart†, I think that he is making the quite depressing point here that dreams will always disappoint in the end because reality can never live up to what you can dream of. This is quite a negative view of the outcome of dreams but is perhaps not entirely critical of the idea of having dreams and something to strive for in the first place. Although it may appear that Fitzgerald is condemning dreaming, I actually believe that in this case he may be more positive about it than it seems at first. The character of Gatsby is portrayed as a dreamer, and these aims and human feelings which he possesses ensure that he is much more of an attractive character than for example, Jordan, who has no such dreams or ambitions for the future and is often associated with words such as â€Å"lazy† and â€Å"cool†. This makes her seem a lot less human than Gatsby and we empathise with him far more, which I think Fitzgerald wants us to do. This suggests that Fitzgerald is supportive of ‘the dreamer’ and tells us that he is not opposed to the idea of dreams in general. In fact he associates the illusion with the phrase â€Å"colossal vitality† which again evokes the idea that dreams are linked with the essence of being human and that Fitzgerald views Gatsby’s dreams with something other than pure criticism. One of the main criticisms which Fitzgerald does have of Gatsby’s dreams is the materialism inherent with them. To gain Daisy’s affections, Gatsby accumulates extortionate wealth and belongings to attract her, and Daisy herself represents something of the materialistic upper class which Gatsby strives to become a part of. This is very concisely put when Gatsby says of Daisy â€Å"her voice is full of money†. Daisy’s voice has particular prominence as a motif throughout the book but at this point it is almost a leit motif as it gains meaning. All we can judge Daisy by is her voice, we never know her thoughts or what she is really thinking as what she says is usually quite empty. By saying that her voice is full of money, Gatsby is pinpointing that superficial charm which she has and perhaps even that in being entranced by her voice he has actually fallen for her wealth. This is an extremely critical way of looking at Gatsby’s feelings and we probably don’t want to believe it of him, but I think we can see it very clearly in Daisy, especially when she sees his Gatsby’s house for the first time. In her exclamation of â€Å"that huge place there? † and her reaction to the extravagant wardrobe, we can see that Fitzgerald is showing Daisy as well as Gatsby to be very focussed on the material and the possessions. I think that this is a point Fitzgerald wants to make on the subject of ‘The American Dream’, of which Gatsby’s own dream is quite symbolic. As Americans, the characters would have been brought up to believe that they could strive to achieve anything and, in short, that nothing was out of their reach. Fitzgerald is not only questioning the belief in this, but also the means of getting to it and is making a point about how society has taken this dream to be something materialistic and to do with what you can own, rather than more spiritual or meaningful dreams. In respects to materialism I think that Fitzgerald is almost purely critical of Gatsby, as what he appears to be searching for is not just Daisy but the entire social and economical class which she represents. Another interesting way in which Fitzgerald portrays Gatsby’s dreams is by making Daisy seem quite an unworthy person to long for. Although, as said in the previous paragraph, she is superficially very beautiful and rich, there appears to be very little under the surface and she tends to talk in quite empty and fantastical phrases such as â€Å"I’d like to just get one of those pink clouds and put you in it and push you around. † In that case Fitzgerald’s alliteration of ‘pink’, ‘put’ and ‘push’, as well as the polysyndeton, make her phrasing seem childish and simple – not really that of someone who could be relied on for a long lasting relationship. In some ways we may think that Fitzgerald is criticising Gatsby’s dreams at this point, after all it seems worthless that he would have spent all this time loving someone who is in fact not worth it at all. This is incredibly clear to us after we see Daisy’s awful behaviour after the accident when she drives away without stopping, and in a way we can see her treatment of Gatsby as quite similar to this, driving along with him, leaving destruction in her wake and escaping away as fast as she can. In this way Fitzgerald is being very critical and it could seem as if his message is that no matter how much you love someone and dream about them, they could just as easily let you down and run away. I think that there is also a slight positive side to Fitzgerald’s choice of making Daisy an unworthy dream, as it shows that everybody can be loved by someone, however this is not very strong as Gatsby does not love Daisy with her faults, and rather it seems that he is just immune to seeing her flaws. Fitzgerald in fact, is probably somewhere in between these views; he is not directly attacking dreams or even Gatsby’s dreams, but he is more in this case attacking Daisy’s character. Although it may be a large lack of judgement skills on Gatsby’s side, we cannot blame him entirely and again we still feel sorry for him when Daisy does eventually let him down. Overall I think that it is clear that there is a strong sense of ambiguity when it comes to Fitzgerald’s attitude to Gatsby’s dreams. However, I feel that the main point he wishes to make is that there is nothing wrong with dreaming, you just have to be careful when choosing your dreams that what you are longing for is actually worthwhile and won’t end up hurting you more than it can make you happy. In Gatsby’s case his aim appears to be more to make us feel sorry that he was so misguided in his choice of dream, rather than to berate him for dreaming at all.

Martin Luther A Biography Of Martin Luther (1483

Martin Luther: A Biography Of Martin Luther (1483-1546) Essay Luther was born in Eisleben, Germany, the son of Hans Luther, who worked in the copper mines, and his wife Margarethe. He went to school at Magdeburg and Eisenach, and entered the University of Erfurt in 1501, graduating with a BA in 1502 and an MA in 1505. His father wished him to be a lawyer, but Luther was drawn to the study of the scriptures, and spent three years in the Augustinian monastery at Erfurt. In 1507 he was ordained a priest, and went to the University of Wittenberg, where he lectured on philosophy and the Scriptures, becoming a powerful and influential preacher. On a mission to Rome in 151011 he was appalled by the corruption he found there. Money was greatly needed at the time for the rebuilding of St. Peters, and papal emissaries sought everywhere to raise funds by the sale of indulgences. The system was grossly abused, and Luthers indignation at the shameless traffic, carried on in particular by the Dominican Johann Tetzel, became irrepressible. As professor of biblical exegesis at Wittenberg (151246), he began to preach the doctrine of salvation by faith rather than works; and on 31 October 1517 drew up a list of 95 theses on indulgences denying the pope any right to forgive sins, and nailed them on the church door at Wittenberg. Tetzel retreated from Saxony to Frankfurt-an-der-Oder, where he published a set of counter-theses and burnt Luthers. The Wittenberg students retaliated by burning Tetzels, and in 1518 Luther was joined in his views by Melanchthon. The pope, Leo X, at first took little notice of this disturbance, but in 1518 summoned Luther to Rome to answer for his theses. His university and the elector interfered, and ineffective negotiations were undertaken by Cardinal Cajetan and by Miltitz, envoy of the pope to the Saxon court. The scholar Johann Eck and Luther held a memorable disputation at Leipzig (1519); and Luther began to attack the papal system more boldly. In 1520 he published his famous address An den christlichen Adel deutscher Nation (Address to the Christian Nobility of the German Nation), followed by a treatise De captivitate Babylonica ecclesiae praeludium (A Prelude concerning the Babylonian Captivity of the Church), which also attacked the doctrinal system of the Church of Rome. A papal bull containing 41 theses was issued against him. He burned it before a multitude of doctors, students, and citizens in Wittenberg. He was excommunicated, and Charles V, Holy Roman Emperor, convened the first Diet at Worms in 1521, before which Luther was called to retract his teachings. Luther refused to relent. An order was issued for the destruction of his books, and he was put under the ban of the Empire. On his return from Worms he was seized, at the instigation of the elector of Saxony, and lodged (for his own protection) in the Wartburg, the electors fortress. During the year he spent there, he translated the Scriptures and composed his cogent controversial treatise, Refutation of the Argument of Latomus. Civil unrest called Luther back to Wittenberg in 1522. He rebuked the unruly elements, and made a stand against lawlessness on the one hand, and tyranny on the other. In the same year Luther published his acrimonious reply to Henry VIIIs attack on him in Assertio septem sacramentorum adversus Martinum Lutherum (1521) about the nature of the seven sacraments. A divergence had gradually taken place also between the views of the Humanist scholar Erasmus and Luther. There was an open breach in 1525, when Erasmus published De libero arbitrio (1524, Discourse on Free Will), and Luther followed with De Servo arbitrio (Concerning the Bondage of Will). .u0e440713a5d78fc2782325d665c12262 , .u0e440713a5d78fc2782325d665c12262 .postImageUrl , .u0e440713a5d78fc2782325d665c12262 .centered-text-area { min-height: 80px; position: relative; } .u0e440713a5d78fc2782325d665c12262 , .u0e440713a5d78fc2782325d665c12262:hover , .u0e440713a5d78fc2782325d665c12262:visited , .u0e440713a5d78fc2782325d665c12262:active { border:0!important; } .u0e440713a5d78fc2782325d665c12262 .clearfix:after { content: ""; display: table; clear: both; } .u0e440713a5d78fc2782325d665c12262 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u0e440713a5d78fc2782325d665c12262:active , .u0e440713a5d78fc2782325d665c12262:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u0e440713a5d78fc2782325d665c12262 .centered-text-area { width: 100%; position: relative ; } .u0e440713a5d78fc2782325d665c12262 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u0e440713a5d78fc2782325d665c12262 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u0e440713a5d78fc2782325d665c12262 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u0e440713a5d78fc2782325d665c12262:hover .ctaButton { background-color: #34495E!important; } .u0e440713a5d78fc2782325d665c12262 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u0e440713a5d78fc2782325d665c12262 .u0e440713a5d78fc2782325d665c12262-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u0e440713a5d78fc2782325d665c12262:after { content: ""; display: block; clear: both; } READ: The North American Frontier Contributed Greatly To Todays Essay In the same year he married Katherine von Bora, a nun who had withdrawn from convent life. In 1529 he engaged with the controversial question of transubstantiation in the famous conference at Marburg with Zwingli and other Swiss theologians; he obstinately maintained his view that Christ is present in the bread and wine of the Eucharist. The drawing up of his theological views in the Augsburg Confession (1530) by Melanchthon, ably representing Luther at the Diet of Augsburg, marks the culmination of the German Reformation. Luther died in Eisleben, and was buried at Wittenberg. Endowed with broad human sympathies, massive energy, manly and affectionate simplicity, and a rich, if sometimes coarse, humour, he was undoubtedly a spiritual genius. His intuitions of divine truth were bold, vivid, and penetrating, if not necessarily philosophical and comprehensive; and he possessed the power of kindling other souls with the fire of his own convictions. His voluminous works include Von den guten Wercken (1520, Of Good Works), and Widder die hymelischen Propheten von den Bildern und Sacrament.
