The red diamond tells how flammable the chemical compound is: how easily it catches fire. The yellow diamond tells about reactivity: how quickly the compound reacts with other materials. (For example, some chemicals, like ammonium nitrate, explode when they touch water; this is an example of reactivity.) The blue diamond tells how dangerous the chemical is to a person's health. Each of these three diamonds - red, yellow, and blue - are given a score between 0 and 4. A score of 0 means there is no danger. A score of 4 means there is the worst possible danger.
The white diamond has codes for "special hazards." For example, if a chemical like ammonium nitrate should not touch water because it will explode, a W with a line through it will be written in the white diamond.
Fluorite
Fluorite is the mineral form of calcium fluoride. It has a chemical formula of CaF where Ca stands for calcium, and F stands for Fluorine.
Fluorite is the main source of fluorine and fluorides. It naturally fluoridates drinking water in places where it is found. It has a hardness of 5. It barely dissolves in water. Geologists have found about 9000 deposits of fluorite found on the Earth. It is mainly mined in China, Mexico and Russia.
Fluoride
Fluoride is the reduced form of fluorine. When fluorine gains an electron by taking it from another substance (oxidizing it), it converts into fluoride. Fluoride is found in toothpaste and helps prevent tooth decay. Fluoride is added artificially to drinking water in some places and has caused a controversy over the harmful effects versus the benefits of fluoridation.
Fluoridation
Fluoridation is the adding of fluorine compounds (fluorides) to various substances, especially toothpaste and drinking water. Government officials, scientists, and doctors say that Fluoridation helps prevent tooth decay and cavities, but it also has harmful effects in larger doses, creating a controversy over whether water should be fluoridated.
Iron(II,III) oxide
Iron(II,III) oxide is a chemical compound. It can be used as an iron ore (source of a material) called magnetite. It is black and brittle. It can oxidize to red iron(III) oxide after some time. It is attracted to magnets. It is a compound that contains iron in two different oxidation states; some of the iron atoms are in a +2 oxidation state and some are in a +3 oxidation state.
Beck, Bogert &amp; Appice
Beck, Bogert & Appice was a hard rock power trio formed by Jeff Beck, Tim Bogert, and Carmine Appice. They released one studio album and one live album.
Beck, Bogert &amp; Appice (album)
Beck, Bogert & Appice is the first album by the '70s band Beck, Bogert & Appice.
Wonderwall (song)
Wonderwall is a single by the rock band Oasis. It was written by Noel Gallagher. Wonderwall comes from "(What's the Story) Morning Glory?", Oasis's second album. The song also appears on "Stop the Clocks" and "Time Flies... 1994-2009". It was the only song that reached the top 10 in America on the Hot 100 for Oasis. It also reached number 1 in four countries and reached the top 10 in 10 countries.
Noel Gallagher says the song was written about a girl he met at a concert when he was touring with Oasis.
It is said that "Wonderwall" was written for Gallagher's then-girlfriend, Meg Mathews. Gallagher now says the song was not about her, but he did say "The meaning of that song was taken away from me by the media who jumped on it. How do you tell your Mrs it's not about her once she's read it is? It's a song about an imaginary friend who's gonna come and save you from yourself."
In 2008 Liam Gallagher said this about the song: "I can't fucking stand that fucking song! Every time I have to sing it I want to gag. Problem is, it was a big, big tune for us." Noel said that Liam, "...thought we had gone too dance when I wrote 'Wonderwall' because the drums didn't go boom-boom bap, boom-boom bap."
The song was recorded at Rockfield Studios in Wales in May of 1995. According to producer Owen Morris, the song was done in 6 to 8 hours.
In the beginning, Noel wanted to sing this song, but he gave his brother Liam Gallagher the choice, and Noel ended up singing "Don't Look Back in Anger". He later said he had only ever wanted to sing "Don't Look Back in Anger", and had used "Wonderwall" as a bargaining tool.
The music video to the song was filmed in the short period when bassist Paul "Guigsy" McGuigan quit the band due to nervous exhaustion; Scott McLeod came in to replace him.
The song won Best British Video at the 1996 BRIT Awards.
Iron(III) chloride
Iron(III) chloride, also known as ferric chloride, is a chemical compound. Its chemical formula is FeCl. It has iron and chloride ions in it. The iron is in its +3 oxidation state.
Iron(III) chloride is a yellow solid. It dissolves in water to make a colloid of iron(III) oxide, making the water look muddy. When it is dissolved in an acidic solution, it is bright yellow. When it is very concentrated in a solution, it is dark brown. It is corrosive to skin and metals. It reacts with iron to produce iron(II) chloride. It fumes hydrochloric acid in moist air. It is a weak oxidizing agent. It reacts with copper(I) chloride to make copper(II) chloride. It breaks down when heated to make chlorine and iron(II) chloride.
It can be made by mixing hydrochloric acid and iron(III) oxide. It can be made by mixing iron and chlorine. It can also be made by reacting iron(II) chloride with chlorine at a low temperature.
It is used in sewage processing. It reacts with slightly basic water to make a "floc" that can remove things from the water. It used to react with copper in circuit boards; iron(III) nitrate is sometimes used too. It is used as a catalyst in making plastics. It is used in certain tests as a reagent.
Iron(II) chloride
Iron(II) chloride, also known as ferrous chloride, is a chemical compound. It is made of iron and chloride ions. The iron is in its +2 oxidation state.
It is grayish-white when anhydrous and greenish when hydrated. It is oxidized by oxygen to a mixture of iron(III) chloride and iron(III) oxide, which are brown-yellow. It dissolves in water to make a yellowish-green solution. It is a reducing agent. It reacts with bases to make greenish iron(II) hydroxide.
It is made by dissolving iron in hydrochloric acid. It can also be made by reacting iron with iron(III) chloride. Some other reducing agents react with iron(III) chloride to make iron(II) chloride.
It does not have common uses. Iron(II) sulfate and iron(III) chloride are used more often. It is used in treating wastewater. It can be used as a reducing agent in organic chemistry.
Iron chloride
Iron chloride may refer to either of these chemicals:
V10 engine
A V10 engine, often just called a V10, is an internal combustion engine with 10 cylinders. The engine has five cylinders on each side called banks. The two banks form a "V"-shaped angle. All ten pistons turn a common crankshaft. A V10 engine can be powered by different types of fuels, including gasoline, diesel and natural gas.
Until recently, V10s had rarely been used for road cars. A V12 runs smoother and is only a little harder to build. A V8 is easier to build and costs less to run. New technology has made the use of V10 engines more practical.
Dodge designed a V10 for use in trucks. The engine was revised and used in the Dodge Viper. Ford developed a heavy-duty V10 engine for use in their trucks.
European car builders later adopted the V10 configuration. High power V10 engines were put into supercars from Lamborghini and Porsche. BMW and Audi then added V10s to their mid-range cars. Volkswagen developed a V10 turbodiesel engine.
