What Are Chemical Equations

A chemical equation is something you will encounter every day in chemistry. Its a written representation, using numbers and symbols, of the process that occurs during a chemical reaction. How to Write a Chemical Equation A chemical equation is written with the reactants on the left side of an arrow and the products of the chemical reaction on the right. The head of the arrow typically points toward the right or the product side of the equation, although some equations may indicate equilibrium with the reaction proceeding in both directions simultaneously. The elements in an equation are denoted using their symbols. Coefficients next to the symbols indicate the stoichiometric numbers. Subscripts are used to indicate the number of atoms of an element present in a chemical species. An example of a chemical equation may be seen in the combustion of methane: CH4 2 O2 → CO2 2 H2O Participants in the Chemical Reaction: Element Symbols Youll need to know the symbols for the elements to understand what is taking place in a chemical reaction. In this reaction, C is carbon, H is hydrogen, and O is oxygen. Left Side of the Equation: Reactants The reactants in this chemical reaction are methane and oxygen: CH4 and O2. Right Side of the Equation: Products The products of this reaction are carbon dioxide and water: CO2 and H2O. Direction of Reaction: Arrow It is the convention to place the reactants on the left side of a chemical equation and the products on the right side. The arrow between the reactants and products should point from left to right or if the reaction is proceeding both ways, point in both directions (this is common). If your arrow points from right to left, its a good idea to re-write the equation the conventional way. Balancing Mass and Charge Chemical equations may be either unbalanced or balanced. An unbalanced equation lists the reactants and products, but not the ratio between them. A balanced chemical equation has the same number and types of atoms on both sides of the arrow. If ions are present, the sum of the positive and negative charges on both sides of the arrow is also the same. Indicating States of Matter Its common to indicate the state of matter in a chemical equation by including parentheses and an abbreviation right after a chemical formula. This can be seen in the following equation: 2 H2(g) O2(g) → 2  H2O(l) Hydrogen and oxygen are indicated by (g), which means they are gases. Water is marked (l), which means it is a liquid. Another symbol you may see is (aq), which means the chemical species is in water — or an aqueous solution. The (aq) symbol is a sort of shorthand notation for aqueous solutions so that water doesnt have to ​be  included in the equation. Its particularly common when ions are present in a solution.

Gilgamesh The Epic Of Gilgamesh - 1194 Words

The Epic of Gilgamesh is a Mesopotamian epic poem loosely based on a real king who ruled sometime around 2700 BCE. The standard version of this epic was written in the Akkadian language. In this epic poem, Gilgamesh is King of Uruk, he is one third mortal and two-thirds god; he is described as a strong, arrogant, and unruly king that does not show much consideration for his actions. Gilgamesh is a very egocentric person; he has no respect for the feelings of others and does not care about how his actions affect the citizens of Uruk. The Gods notice the unruliness of Gilgamesh and conjure up Enkidu to defeat Gilgamesh. Instead of becoming enemies, Enkidu and Gilgamesh become friends, but their friendship is short lived when Enkidu dies, which leaves Gilgamesh to extremely grieve for the loss of his friend. In order to avoid death Gilgamesh seeks out immortality from a man called Utanapishtam. Unfortunately Gilgamesh soon learns that he cannot escape death because he finally comes to terms with his own mortality and discovers that death is inevitable. The contrasting themes of love and friendship, fear of failure, inevitability of death, and wisdom of experience that occur throughout the Epic of Gilgamesh show how man cannot escape his own mortality no matter how hard he tries. The theme of love and friendship is a dominant theme throughout the epic mainly because this epic follows the relationship between Gilgamesh and Enkidu.

Beloved

Beloved-Water Motif Essay Beloved In her novel Beloved, Toni Morrison writes about the life of former slaves of Sweet Home. Sethe, one of the main characters, was once a slave to a man and his wife, Mr. and Mrs. Garner. After Garners sudden death, schoolteacher comes to Sweet Home and takes control of the slaves. His treatment of all the slaves forced them to run away. Fearing that her children would be sold, Sethe sent her two boys and her baby girl ahead to her mother-in-law. On the way to freedom, a white girl named Amy Denver helped Sethe deliver her daughter, who she later names Denver. About a month after Sethe escapes slavery, schoolteacher found her and tried to bring her back. In fear that her children would be brought back into slavery, Sethe killed her older daughter and attempted to kill Denver and her boys. Sethe, along with Denver, was sent to prison and spent three months there. Buglar and Howard, her two sons, eventually ran away. After about eighteen years, another ex-slave from Sweet Home, Paul D., came to live with Sethe and Denver. A few days later, while coming home from a carnival, Sethe, Paul D., and Denver found a young woman of about twenty on their porch. She claimed her name is Beloved. They took her in and she lived with them. Throughout the novel, Morrison uses many symbols and imagery to express her thoughts and to help us better understand the characters. Morrison uses the motif of water throughout the novel to represent birth, re-birth, and escape to freedom. In Beloved, one of the things that water represents is birth. When Sethe was running away form Sweet Home, she was pregnant. In order to get to freedom, she had to cross the Ohio River. On the way to the river, Sethe met a young white girl named Amy Denver. Amy helped Sethe to keep going because her feet were swollen up. When Sethe and Amy got to the river, Sethe thought the baby had died during the previous night. However, she soon felt the signs of labor. It looked like home to her, and the baby (not dead in the least) must have thought so too. As soon as Sethe got close to the river her own water broke loose to join it. The break, followed by the redundant announcement of labor, arched her back (p. 83). Sethe crawled into a boat that soon began to fill with water. It was in this boat that Sethe gave birth to Denver. When a foot rose from the riverbed and kicked the bottom of the boat and Sethes behind, she knew it was done and permitted herself a short faint (p. 84). In these two passages, water signifies birth. Denver was thought to be dead until Sethe reached the river, a large body of water. Also, Denver is actually born in the water because the boat that Sethe was in was filled up with water. When Beloved first appears at Sethes house, Sethe leans in to look at the womans face. As she does so, she suddenly feels a great need to relive herself. She never made the outhouse. Right in front of its door she had to lift her skirts, and the water she voided was endless. Like a horse, she thought, but as it went on and on she thought, No, more like flooding the boat when Denver was born (p.50). When Sethe looked at Beloveds face, her bladder filled up. When she was relieving herself, the amount of urine reminded her of flooding the boat when her water broke at the time Denver was born. .ud9a0a530de9336c01b00c91bd4c18ed9 , .ud9a0a530de9336c01b00c91bd4c18ed9 .postImageUrl , .ud9a0a530de9336c01b00c91bd4c18ed9 .centered-text-area { min-height: 80px; position: relative; } .ud9a0a530de9336c01b00c91bd4c18ed9 , .ud9a0a530de9336c01b00c91bd4c18ed9:hover , .ud9a0a530de9336c01b00c91bd4c18ed9:visited , .ud9a0a530de9336c01b00c91bd4c18ed9:active { border:0!important; } .ud9a0a530de9336c01b00c91bd4c18ed9 .clearfix:after { content: ""; display: table; clear: both; } .ud9a0a530de9336c01b00c91bd4c18ed9 { 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; } .ud9a0a530de9336c01b00c91bd4c18ed9:active , .ud9a0a530de9336c01b00c91bd4c18ed9:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .ud9a0a530de9336c01b00c91bd4c18ed9 .centered-text-area { width: 100%; position: relative ; } .ud9a0a530de9336c01b00c91bd4c18ed9 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .ud9a0a530de9336c01b00c91bd4c18ed9 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .ud9a0a530de9336c01b00c91bd4c18ed9 .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; } .ud9a0a530de9336c01b00c91bd4c18ed9:hover .ctaButton { background-color: #34495E!important; } .ud9a0a530de9336c01b00c91bd4c18ed9 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .ud9a0a530de9336c01b00c91bd4c18ed9 .ud9a0a530de9336c01b00c91bd4c18ed9-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .ud9a0a530de9336c01b00c91bd4c18ed9:after { content: ""; display: block; clear: both; } READ: Dr Faustus as a Tragic Hero Essay Denvers birth is associated many times with water. Throughout her novel, Toni Morrison also uses the motif of water to signify re-birth. When we first meet Beloved, Morrison writes, A fully dressed woman walked out of the water (p. 50). In this passage, Beloved, the daughter that Sethe murdered 18 years ago, comes back to the world of the living. She comes straight out of the water. Here, water signifies the re-birth of Beloved. When Beloved is taken into the house, the only thing she asks for is water. She said
