Ford Expedition

The 2007 Expedition was launched at the Houston Auto Show rather than at Detroit, Los Angeles, or New York where most new models are, as 20% of all Expedition sales are in Texas. For example, gold is quite common in Turkey but considered a most valuable gift in Sicily. The Expedition EL can be distinguished by its longer rear-quarter windows; and the rear passenger doors do not cut into the aft wheel well trim. The symbolic value of gold varies wildly around the world, even within geographic regions. It is scheduled to be launched with the standard wheelbase 2007 Expedition in the summer of 2006. In Orthodox Christianity, the wedded couple is adorned with a golden crown during the ceremony, an amalgamation of symbolic rites. The Expedition EL is about 15.8 inches (40 cm) longer than the standard Expedition, for a total of approximately 222 inches (18.5 feet or 563 cm), and has a 131 inch (333 cm) wheelbase, producing 24 cubic feet of additional cargo space over the standard 119 inch (302 cm) wheelbase model. Wedding rings are traditionally made of gold; since it is long-lasting and unaffected by the passage of time, it is considered a suitable material for everyday wear as well as a metaphor for the relationship.

An extended-wheelbase version of the Expedition, called the Expedition EL (for "extended length"), will replace the cancelled Excursion, and is expected to compete more effectively with the Chevrolet Suburban and GMC Yukon XL. Medieval kings were inaugurated under the signs of sacred oil and a golden crown, the latter symbolizing the eternal shining light of heaven and thus a Christian king's divinely inspired authority. It is powered by the 5.4-liter Triton V-8 engine, rated at 300 horsepower and 365 pound-feet of torque, which when properly equipped can tow up to 9,100 pounds. Winners of races and prizes are usually awarded the gold medal (such as the Olympic Games and the Nobel Prize), while many award statues are depicted in gold (such as the Academy Awards, the Emmy Awards and the British Academy Film Awards). The new platform provides 10% more torsional rigidity than the previous model, and includes the independent rear suspension. Great human achievements are frequently rewarded with gold, in the form of medals and decorations. For 2007, the Expedition will be redesigned, utilizing the T1 platform originally launched with F-150. Gold is associated with notable anniversaries, particularly in a 50 year cycle, such as a golden wedding anniversary, golden jubilee, etc.

Engine options:. On the other hand, eminent orators such as John Chrysostom were said to have a mouth of gold with a silver tongue. The Expedition uses the code U1 in the 5th and 6th positions of the VIN. American Indians of the Sioux tribe called it "The yellow metal that makes the white man crazy". AdvanceTrac® with Roll Stability Control™ is optional for 2005. In Communist propaganda, the golden pocket watch and its fastening golden chain were the characteristic accessories of the class enemy, the bourgeois and the industrial tycoons. The base 4.6 L V8 engine was dropped in 2005 as the 5.4 L V8 was updated with 24-valve technology. The Golden Calf is a widely-recognised symbol of idolatry and revolt against God.

A popular new feature is power folding third-row seats. Gold has been associated with the extremities of utmost evil and great sanctity throughout history. The 2003 Expedition shares the Ford U platform for 8,300 lb (3,800 kg) towing and a more refined ride. Gold used in dentistry is widely regarded as the safest form of restorative material, as well as the most successful. Engines:. Liver and kidney damage has, however, been reported for up to 50% of arthritis patients treated with gold-containing drugs. The truck was refreshed in 1999 with more power and updated trim. The human body does not absorb gold very well, thus compounds of gold are not normally very toxic.

Seating capacity ranged up to nine passengers with the third-row rear seat option, and the Expedition could tow 8,000 lb (3,600 kg). There is only one stable isotope of gold, and 18 radioisotopes with Au-195 being the most stable with a half-life of 186 days. It replaced the full size Ford Bronco. Gold also forms:. The Expedition was designed to compete with both the larger Chevrolet Suburban, and the smaller Chevrolet Tahoe and GMC Yukon, as well as Toyota's Land Cruiser. Such compounds containing the Au^- anion are called aurides and include caesium auride, CsAu, rubidium auride, RbAu, and tetramethylammonium auride, (CH₃)₄N⁺ Au^-. . Gold also can under extreme conditions form a +5 state with fluorine (gold pentafluoride, AuF₅), as well as (unusually for a metal), a -1 state.

One million Expeditions have sold since 2004, reflecting high consumer demand for it's family-friendly interior, cargo space, and high towing capacity. Gold compounds can be aurous (univalent, +1) or auric (trivalent, +3). It is similar to the Lincoln Navigator, especially for 2004 with the introduction of the Limited trim line. Although gold is a noble metal, it can form many compounds, auric chloride (AuCl₃) and chlorauric acid (HAuCl₄) being the most common. The Expedition offers up to nine passenger seating and a range of V8 engines. Roosevelt expropriated gold by Executive Order 6102, and President Richard Nixon closed the gold window by which foreign countries could exchange American dollars for gold at a fixed rate. Introduced in 1997 and significantly refreshed for 2003, it slots between the smaller Ford Explorer, and the now discontinued Ford Excursion. President Franklin D.

The Ford Expedition is a Full-size SUV built by the Ford Motor Company. Within the United States, the private possession of gold except as jewelry and coin collecting was banned between 1933 and 1975. 2005-2006 5.4 L 3-valve V8, 300 hp (223 kW). Because of its use as a reserve store of value, the possession of gold is sometimes restricted or banned. 2003-2005 5.4 L V8, 260 hp (194 kW). Prices have risen to the $570/oz ($18,300/kg) mark in early 2006 [3]. 2003-2005 4.6 L V8, 232 hp (173 kW). Since 1968 the price of gold on the open market has ranged widely, with a record high of $850/oz ($27,300/kg) on 21 January 1980, to a low of $252.90/oz ($8,131/kg) on 21 June 1999 (London Fixing).

5.4 L V8, 260 hp (194 kW) 1999-2002. Federal Reserve Bank, in New York. 5.4 L V8, 230 hp (172 kW) 1997-1998. The largest gold depository in the world is that of the U.S. 4.6 L V8, 240 hp (179 kW) 1999-2002. Central banks still hold historical gold reserves as a store of value although the level has generally been declining. 4.6 L V8, 215 hp (160 kW) 1997-1998. On March 17, 1968, economic circumstances caused the collapse of the gold pool, and a two-tiered pricing scheme was established whereby gold was still used to settle international accounts at the old $35.00 per troy ounce ($1.13/g) but the price of gold on the private market was allowed to fluctuate; this two-tiered pricing system was abandoned in 1975 when the price of gold was left to find its free-market level.

By 1961 it was becoming hard to maintain this price, and a pool of US and European banks began to act together to defend the price against market forces. For a long period the United States government set the price of gold at $20.67 per troy ounce ($664.56/kg) but in 1934 the price of gold was set at $35.00 per troy ounce ($1125.27/kg). As part of this system, governments and central banks attempted to control the price of gold by setting values at which they would exchange it for currency. Historically gold was used to back currency in an economic system known as the gold standard in which one unit of currency was equivalent to a certain weight of gold.

The price of gold is determined on the open market, but a procedure known as the Gold Fixing in London, originating in 1919, provides a twice-daily benchmark figure to the industry. The purity of a gold bar can also be expressed as a decimal figure ranging from 0 to 1, known as the millesimal fineness, such as 0.995. When it is alloyed with other metals the term carat or karat is used to indicate the amount of gold present, with 24 carats being pure gold and lower ratings proportionally less. Like other precious metals, gold is measured by troy weight and by grams.

No commercially viable mechanism for performing gold extraction from sea water has yet been identified. The effort produced little gold and cost the German government far more than the commercial value of the gold recovered. Unfortunately, his assessment of the concentration of gold in sea water was unduly high, probably due to sample contamination. Fritz Haber (the German inventor of the Haber process) attempted commercial extraction of gold from sea water in an effort to help pay Germany's reparations following the First World War.

The world's oceans hold a vast amount of gold, but in very low concentrations (perhaps 1-2 parts per billion). The possibility of cheap man-made gold would have unforeseen economic and political consequences. No economically feasible method to manufacture gold artificially has been found and published yet. However, it is possible to obtain infinitesimally small amounts of gold by artificial nuclear transformations in particle accelerators The gold isotopes produced would likely be radioactive.

Modern science has since proven the impossibility of making gold from other elements via chemical reactions. porcelain), while searching in vain for the philosopher's stone, which was supposed to turn mercury into gold. Scientists, kings and charlatans obsessed with the secret art of alchemy accidentally invented practically useful materials (e.g. The idea of producing gold out of lesser metals or other cheap substances has fascinated people throughout the centuries.

Other methods of assaying and purifying smaller amounts of gold include parting and inquartation as well as cuppelation, or refining methods based on the dissolution of gold in aqua regia. After initial production, gold is often subsequently refined industrially by the Wohlwill process or the Miller process. In South America, the controversial project Pascua Lama aims at exploitation of rich fields in the high mountains of Atacama, at the border between Chile and Argentina. Kolar Gold Fields in India is another example of a city being built on the greatest gold deposits in India.

Siberian regions of the USSR also used to be significant in the global gold mining industry. Mines in South Dakota and Nevada supply two-thirds of gold used in the United States. Other major producers are Canada, United States and Western Australia. The Second Boer War of 1899–1901 between the British Empire and the white Boers was at least partly over the rights of miners and possession of the gold wealth in South Africa.

Gold fields in the Orange Free State and the Transvaal are deep and require the world's deepest mines. The city of Johannesburg was built atop the world's greatest gold finds. This decline was due to the increasing difficulty of extraction and changing economic factors affecting the industry in South Africa. Production in 1970 accounted for 79% of the world supply, producing about 1,000 tonnes, however production in 2004 was 342 tonnes.

Since the 1880s South Africa has been the source for a large proportion of the world's gold supply. It is claimed, that all the gold that has been mined throughout the history of mankind could be incorporated in a solid ball with a diameter of 27 metres. Ore grades of 30 g/1000 kg (30 ppm) are usually needed before gold is visible to the naked eye, therefore in most gold mines you will not see any gold. Economic gold extraction can be achieved from ore grades as little as 0.5 g/1000 kg (0.5 ppm) on average in large easily mined deposits, typical ore grades in open-pit mines are 1–5 g/1000 kg (1-5 ppm), ore grades in underground or hard rock mines are usually at least 3 g/1000 kg (3 ppm) on average.

Gold occurs in sea water at 0.1 to 2 mg/t (0.1 to 2 ppb by weight) depending on sample location. Another important ore type is in sedimentary black shale and limestone deposits containing finely disseminated gold and other platinum group metals. In all these deposits the gold is in its native form. Primary deposits can be weathered and eroded, with most of the gold being transported into stream beds where it congregates with other heavy minerals to form placer deposits.

There are several primary deposit types, common ones are termed reef or vein. A deposit usually needs some form of secondary enrichment to form an economically viable ore deposit: either chemical or physical processes like erosion or solution or more generally metamorphism, which concentrates the gold in sulfide minerals or quartz. The primary source of gold is usually igneous rocks or surface concentrations. Hydrothermal ore deposits of gold occur in metamorphic rocks and igneous rocks; alluvial deposits and placer deposits originate from these sources.

Gold is widely distributed in the Earth's crust at a background level of 0.03 g/1000 kg (0.03 ppm by weight). Rarer mineral associations are petzite, calaverite, sylvanite, muthmannite, nagyagite and krennerite. The most common sulfide associations are pyrite, chalcopyrite, galena, sphalerite, arsenopyrite, stibnite and pyrrhotite. Common gold associations are quartz often as veins and sulfide minerals.

These grains occur between mineral grain boundaries or as inclusions within minerals. Occasionally large accumulations of native gold (also known as nuggets) occur but usually gold occurs as minute grains. Due to its relative chemical inertness gold is usually found as the native metal or alloy. Because of its historically high value, much of the gold mined throughout history is still in circulation in one form or another.

During the 19th century, gold rushes occurred whenever large gold deposits were discovered, including the California, Colorado, Otago, Australia, Witwatersrand, Black Hills, and Klondike gold rushes. For modern attempts to produce artificial gold, see gold synthesis. Their symbol for gold was the circle with a point at its center (☉), which was also the astrological symbol, the Egyptian hieroglyph and the ancient Chinese character for the Sun (now 日). Although they never succeeded in this attempt, the alchemists promoted an interest in what can be done with substances, and this laid a foundation for today's chemistry.

The primary goal of the alchemists was to produce gold from other substances, such as lead — presumably by the interaction with a mythical substance called the philosopher's stone. Gold in antiquity was relatively easy to obtain geologically; however, 75% of all gold ever produced has been extracted since 1910.[2] It has been estimated that all the gold in the world that has ever been refined would form a single cube 20 m (66 ft) a side. Gold has been used as a symbol for purity, value, royalty, and particularly roles that combine these properties (see gold album). Gold has long been considered one of the most precious metals, and its value has been used as the standard for many currencies (known as the gold standard) in history.

The European exploration of the Americas was fueled in no small part by reports of the gold ornaments displayed in great profusion by Native American peoples, especially in Central America, Peru, and Colombia. Exploitation is said to date from the time of Midas, and this gold was important in the establishment of what is probably the world's earliest coinage in Lydia between 643 and 630 BC. The south-east corner of the Black Sea was famed for its gold. Gold is also mentioned several times in the Old Testament.

Egypt and Nubia had the resources to make them major gold-producing areas for much of history. Egyptian hieroglyphs from as early as 2600 BC describe gold, which king Tushratta of the Mitanni claimed was as "common as dust" in Egypt. It may have been the first metal used by humans and was valued for ornamentation and rituals. Gold ( Sanskrit jval, Greek χρυσóς [khrisós], Latin aurum for "shining dawn", Anglo-Saxon gold, Chinese 金 [jīn],Japanese 金 [kin] ) has been known and highly valued since prehistoric times.

Because of its high electrical conductivity and resistance to corrosion and other desirable combinations of physical and chemical properties, gold also emerged in the late 20th century as an essential industrial metal. Gold and its many alloys are most often used in jewelry, coinage and as a standard for monetary exchange in many countries. Pure gold is too soft for ordinary use and is hardened by alloying with silver, copper, and other metals. [1].

Recent research undertaken by Frank Reith of the Australian National University shows that microbes play an important role in the formation of gold deposits, transporting and precipitating gold to form grains and nuggets that collect in alluvial deposits. The added metal is oxidized and dissolves allowing the gold to be displaced from solution and be recovered as a solid precipitate. Gold ions in solution are readily reduced and precipitated out as gold metal by the addition of virtually any other metal as the reducing agent. Common oxidation states of gold include +1 (gold(I) or aurous compounds) and +3 (gold(III) or auric compounds).

Heat, moisture, oxygen, and most corrosive agents have very little chemical effect on gold, making it well-suited for use in coins and jewelry; conversely, halogens will chemically alter gold, and aqua regia dissolves it. Gold is a good conductor of heat and electricity, and is not affected by air and most reagents. As the amount of silver increases, the color becomes whiter and the specific gravity lower. Native gold contains usually eight to ten per cent silver, but often much more — alloys with a silver content over 20% are called electrum.

Adding copper yields a redder metal, iron blue, Silver produces green, aluminium purple, platinum metals white, and natural bismuth together with silver alloys produce black. This can be done to increase its strength, or create several exotic colors, sold for instance in the western United States to the tourist trade as "Black Hills" gold. A soft metal, gold will readily form alloys with many other metals. It is the most malleable and ductile metal known; a single gram can be beaten into a sheet of one square metre, or an ounce into 300 square feet.

Only silver colloids exhibit the same interactions with light, albeit at a shorter frequency, making silver colloids yellow in color. These colors are the result of gold's plasmon frequency lying in the visible range, which causes red and yellow light to be reflected, and blue light to be absorbed. Gold is a metallic element with a characteristic yellow color, but can also be black or ruby when finely divided, while colloidal solutions are intensely colored and often purple. .

Its ISO currency code is XAU. Gold forms the basis for a monetary standard used by the International Monetary Fund (IMF) and the Bank for International Settlements (BIS). For millennia, gold has served as money and is also used in jewelry, dentistry, and in electronics. The metal occurs as nuggets or grains in rocks and in alluvial deposits and is one of the coinage metals.

A soft, shiny, yellow, dense, malleable, ductile (trivalent and univalent) transition metal, gold does not react with most chemicals but is attacked by chlorine, fluorine and aqua regia. Gold is a chemical element in the periodic table that has the symbol Au (from the Latin aurum) and atomic number 79. The Columbia Electronic Encyclopedia, 6th ed. Los Alamos National Laboratory – Gold.

Gold hydrazide: an olive-green powder, AuN₂H₃, one of several explosive compounds known archaically as aurum fulminans. Gold cluster compounds. Gold chalcogenides (O, S, Se,Te). Gold halides (F,Cl,Br,I).

The AuCl₄^- ion after dissolving in aqua regia. Green gold (a gold/silver alloy) is used in specialized jewelry while gold alloys with copper (reddish color) are more widely used for that purpose (rose gold)*. White gold (an alloy of gold with platinum, palladium, nickel, and/or zinc) serves as a substitute for platinum. Only the salts and radioisotopes (mentioned above) have any evidence of medicinal value.

For similar reasons, it also used as the basis for some superstitious, over the top, health claims. Some use it as an excuse to create super-expensive delicacies ($1,000 cocktails). Having no reactivity it adds no taste but is taken as a delicacy. Called varak or (varaq) in India.

Gold flake is used on and in some gourmet sweets and drinks. The gold isotope Au-198, (half-life: 2.7 days) is used in some cancer treatments and for treating other diseases. However, it can also cause photosensitive rashes, gastrointestinal disturbance, and kidney damage. It inhibits lymphocyte proliferation, lysosomal enzyme release, the release of reactive oxygen species from macrophages, and IL-1 production.

Disodium aurothiomalate is a treatment for rheumatoid arthritis (administered intramuscularly). Since it is a good reflector of both infrared and visible light, it is used for the protective coatings on many artificial satellites. Many competitions and honors, such as the Olympics and the Nobel Prize, award a gold medal to the winner (with silver to the second-place finisher, and bronze to the third.). Gold is used as a coating enabling biological material to be viewed under a scanning electron microscope.

It is also the usual starting point for making other gold compounds. Gold(III) chloride is used as a catalyst in organic chemistry. Chlorauric acid is used in photography for toning the silver image. It is also the form used as gold paint on ceramics prior to firing.

Colloidal gold (a gold nanoparticle) is an intensely colored solution that is currently studied in many labs for medical, biological and other applications. Gold is used in restorative dentistry especially in tooth restorations such as crowns and bridges. The resistance to oxidation of gold has led to its widespread use as thin layers electroplated on the surface of electrical connectors to ensure a good connection. Gold performs critical functions in computers, communications equipment, spacecraft, jet aircraft engines, and a host of other products.

Gold can be made into thread and used in embroidery.
