Coca-Cola, is a carbonated, sweetened soft drink and is the world's best-selling drink. A popular nickname for Coca-Cola is Coke. The Coca-Cola Company claims that the beverage is sold in more than 200 countries. The company's headquarters are in Atlanta, Georgia. Coca-Cola's main rival is Pepsi because of the similar taste of their main product. Coca-Cola has 7 cubes of sugar, whereas Pepsi has 8 cubes of sugar. The Coca-Cola Company is proud to have a long history of sponsoring major events, organizations and projects around the world. Among their most well known sponsorships are American Idol, Apple iTunes, BET Network, NASCAR, NBA, NCAAmarvel and the Olympic Games. After their products were put back on sale in Myanmar in 2012, the only countries that Coca-Cola can not be bought officially are Cuba and North Korea, due to trade bans with the US.
Coca-Cola was first made in the 1800s by John Pemberton. The first sales were at Jacob's Pharmacy in Atlanta, Georgia, on May 8, 1886. They sold it there for five cents a glass, it was very strong tasting because they did not mix it with water. Coca-Cola was first made the way it is now in Columbus, Georgia. It was called Pemberton's French Wine Coca at first, and was sold as a medicine to help cure colds and give people more energy. The drink used to be sold at soda fountains in the United States. It was also created to stop addictions to morphine.
Coca-Cola was first sold in bottles in Atlanta on March 12, 1894 with actual cocaine content. It was first sold in cans in 1955. During the first year, sales were about only nine drinks per day. Dr. Pemberton did not think he could make a lot of money with the drink he invented, so he sold parts of his business to different people. Just before he died in 1888, he sold the rest of his Coca-Cola business to Asa G. Candler. Mr. Candler, together with some other businessmen, started the Coca-Cola Company.
Candler became mayor of Atlanta and gave most of his shares of Coca-Cola to his children. In 1919 the family sold control of Coca-Cola to Ernest Woodruff.
In 1923 Woodruff's son Robert Winship Woodruff became president of Coca-Cola,replacing Asa Candler's son Charles Howard Candler.
The drink is called "Coca-Cola" because of the coca leaf and kola fruits that were used to add flavor. Dr. Pemberton's partner and bookkeeper, Frank Robinson, suggested the name "Coca-Cola" because he thought using the letter C twice would look better than if they used a K in the word "Cola". He then wrote down the name to use as a logo that is now very famous. The recipe was altered after a short while, after the cocaine/coca leaf reportedly caused cases of hallucinations. Coca has not been used in the formula since 1903.
Coca-Cola was the first ever sponsor of the Olympic Games. This was for the 1928 Olympic Games in Amsterdam.
The company sells many other products, including other sorts of Coca-Cola, such as Diet Coke (1981), Cherry Coke (1985), Diet Cherry Coke (1986), Diet/Coke with Lemon (2001), Diet Vanilla Coke (2002), Diet/ Coke with Lime (2004), Coke Zero (2006), Coca-Cola with Orange (2007), Diet Coke Citrus Zest (2007). Based on Interbrand's best global brand 2011, Coca-Cola was the world's most valuable brand.
Sulfur
Sulfur (or sulphur) is a chemical element. The symbol for sulfur is S, and its atomic number is 16.
Sulfur is a yellow solid that is a nonmetal. It is fragile (easily broken) and crystalline. It burns easily, releasing toxic fumes of sulfur dioxide. It has a very faint odor. If it is melted and cooled very quickly, it makes a rubbery form of sulfur that is called "plastic sulfur". It gradually turns back into the yellow brittle form. It does not dissolve in water. The smell normally known as "sulfur" comes from hydrogen sulfide and similar chemicals. These sulfides are produced when things decay without air.
Sulfur compounds are chemical compounds containing sulfur ions. Sulfur comes in several forms: oxidation states of -2 (hydrogen sulfide), +4 (sulfur dioxide, sulfites) and +6 (sulfuric acid, sulfates) are most common, although there are other oxidation states.

Sulfur can be found in the earth near volcanoes. Many minerals contain sulfur ions. Coal contains sulfur ions which are released when it burns. Hydrogen sulfide and sulfur dioxide are some sulfur compounds that are released when coal burns. They are reacted to make sulfur. Sulfur in the ground in melted, then forced up through pipes by compressed (squeezed) air.
Sulfur is commonly used in gunpowder, medicine, and matches. Matches release sulfur dioxide when they burn, giving them their smell. Sulfur is an essential component to living cells. Many proteins contain sulfur. It is also used as a pesticide on organic farms.
Powder sulfur is said to be left after an occurrence of a supernatural being.
Sulfur is not toxic, but the chemical compounds formed when sulfur burns can be very toxic. Sulfuric acid, for example, can make paper turn black!
The ancient name for sulfur is "brimstone". Sulfur was used in fumigation (making fumes) and medicine in ancient Greece. In 1777, Antoine Lavosier convinced the scientific community that sulfur was an element.
Aluminium
Aluminium (in American and Canadian English also: aluminum) is a chemical element. The symbol for aluminium is Al, and its atomic number is 13. Aluminium is the most abundant metal. It is a mononuclidic element.
People have tried to produce aluminium since 1760. The first successful attempt, finished in 1824 by Danish physicist and chemist Hans Christian Ørsted. He reacted anhydrous aluminium chloride with potassium amalgam, yielding a lump of metal looking similar to tin. He presented his results and showed a sample of the new metal in 1825. In 1827, German chemist Friedrich Wöhler repeated Ørsted's experiments but did not identify any aluminium. (The reason for this inconsistency was only discovered in 1921.) He conducted a similar experiment in the same year by mixing anhydrous aluminium chloride with potassium and produced a powder of aluminium. In 1845, he was able to produce small pieces of the metal and described some physical properties of this metal. For many years thereafter, Wöhler was credited as personewho discovered of aluminium.
Aluminium is a very good conductor of electricity and heat. It is light and strong. It can be hammered into sheets (malleable) or pulled out into wires (ductile). It is a highly reactive metal, although it is corrosion resistant.
A fresh film of aluminium is a good reflector of visible light and an excellent reflector of medium and far infrared radiation.
Aluminium prevents corrosion by forming a small, thin layer of aluminium oxide on its surface. This layer protects the metal by preventing oxygen from reaching it. Corrosion can not occur without oxygen. Because of this thin layer, the reactivity of aluminium is not seen. As a powder it burns hot. Uses include fireworks displays and rocket fuel.
Pure aluminium is made from bauxite, a kind of rock that has aluminium oxide and many impurities. The bauxite is crushed and reacted with sodium hydroxide. The aluminium oxide dissolves. Then the aluminium oxide is dissolved in liquid cryolite, a rare mineral. Cryolite is normally produced artificially though. The aluminium oxide is electrolyzed to make aluminium and oxygen. The largest producer of aluminium is China. China produces about 31,873 thousand tonnes of aluminium.
Aluminium was once considered a precious metal that was even more valuable than gold. This is no longer true because, as technology improved, it became cheaper and easier to make pure metal.
