Colossus at Rhodes essays

Colossus at Rhodes essays Ancient Greece, a land of great history, was home to one of the seven ancient wonders, the Colossus of Rhodes. In 408 BC, three city-states in Greece, (which are states consisting of sovereign cities), Ialysos, Kamiros, and Lindos, united and formed one area. This was to become Rhodes, the capital of the three city-states. Rhodes then established itself as a powerful city, becoming economically and commercially powerful while allying with Ptolemy I Soter of Egypt. However, in 305 BC, the Antigonids, who were powerful political leaders in Macedonia, rivaled with the Ptolemies and attempted to take over Rhodes in order to disconnect the alliance between the Egyptian and Rhode peoples. The Antigonids leader was Antigous, who sent his son, Demitrius, along with 40,000 men and Aegean pirates, to conquer Rhodes (Unmuseum). The Antigonids attempts were futile; they could not break through into the city. A strong, tall tower protected the city, which was wooden and armed with catapults that could be moved on the wall. Fortunately for Rhodes, the Antigonids left behind their weaponry and embraced a peace agreement. In celebration of their victory, the Rhodians sold the weapons and erected the Colossus, a massive statue, which they dedicated to the sun God, Helios (The Seven Wonders). To build the statue, they melted down bronze from the war machines. It was made from the bronze plates and it stood over an iron framework. According to the book of Pilon of Byzantium, 15 tons of bronze and 9 tons of iron were used to build the Colossus. The statue had several stone columns within it and iron beams were driven into the stone and connected with the bronze outer skin (Unmuseum). The Colossus stood one hundred and ten feet high upon a fifty-foot pedestal. According to Pliny the Elder, a Historian, the statue was a product of twelve years of hard work. The Colossus is located off the Southwestern tip of A ...

Why You Should Not Mix Alcohol and Bleach

Why You Should Not Mix Alcohol and Bleach Mixing alcohol and bleach is never a good idea, as the combination results in chloroform, a powerful sedative that can cause you to pass out. You should always be careful when handling these chemicals. Chemical Reaction Ordinary household bleach contains sodium hypochlorite, which reacts with ethanol or isopropyl alcohol to produce chloroform (CHCl3), hydrochloric acid  (HCl),  and other compounds, such as chloroacetone or dichloroacetone. Unintentional mixing of these chemicals could occur from trying to clean up a spill using bleach or from mixing cleaners together. Bleach is highly reactive and forms dangerous compounds when mixed with any number of chemicals, so its best to avoid combining it with other products. Dangers of Chloroform Chloroform is a dangerous chemical that irritates the eyes, respiratory system, and skin. It can damage the nervous system, eyes, lungs, skin, liver, kidneys, and other organs and may even cause cancer. The chemical is readily absorbed into the body through the skin and through inhalation and ingestion. If you suspect that you have been exposed to chloroform, remove yourself from the contaminated area and seek medical attention. Chloroform is a potent anesthetic that can knock you out. It is also the cause of sudden sniffers death, a fatal cardiac arrhythmia some people experience upon exposure. Over time, chloroform in the presence of oxygen (as in air) naturally degrades to produce phosgene, dichloromethane, carbon monoxide, formyl chloride, carbon dioxide, and hydrogen chloride. Even once the chloroform has broken down, you should avoid these chemicals. Phosgene, for example, is a notorious chemical agent. It was responsible for around 85 percent of the deaths from chemical weapons during World War I. Disposing of a Bleach and Alcohol Mixture If you accidentally mix these chemicals and need to dispose of the waste, dont try to neutralize it. First, use caution and do not enter the contaminated area if you smell chloroform, which has a heavy, sweet-smelling odor. Once the smell begins to dissipate, dilute the mixture with large volumes of water and wash it down the drain as quickly as possible. Acetone and Bleach Although this is a less common mixture, do not mix acetone and bleach, either, as this reaction also produces chloroform: 3NaClO C3H6O → CHCl3   2NaOH NaOCOCH3 Ultimately, mixing bleach with any chemical except water is an extremely bad idea. Bleach reacts with vinegar, ammonia, and most household cleaners to produce toxic fumes.
