Chile Saltpeter
Nitratine or nitratite, also known as cubic niter (UK: nitre), soda niter or Chile saltpeter (UK: Chile saltpetre), is a mineral, the naturally occurring form of sodium nitrate, NaNO3. Chemically it is the sodium analogue of saltpeter. Nitratine crystallizes in the trigonal system, but rarely occurs as well formed crystals. It is isostructural with calcite. It is quite soft and light with a Mohs hardness of 1.5 to 2 and a specific gravity of 2.24 to 2.29. Its refractive indices are nω=1.587 and nε=1.336. The typical form is as coatings of white, grey to yellowish brown masses. The rare crystals when found typically have the scalenohedral form of the calcite structure. It is found only as an efflorescence in very dry environments. It is very soluble in water such that it is deliquescent and will absorb water out of the air and turn into a ''puddle'' of sodium nitrate solution when exposed to humid air. Nitratine was once an important source of nitrates for fertilizer and other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nitrate Minerals
Nitrate is a polyatomic ion with the chemical formula . Salts containing this ion are called nitrates. Nitrates are common components of fertilizers and explosives. Almost all inorganic nitrates are soluble in water. An example of an insoluble nitrate is bismuth oxynitrate. Structure The ion is the conjugate base of nitric acid, consisting of one central nitrogen atom surrounded by three identically bonded oxygen atoms in a trigonal planar arrangement. The nitrate ion carries a formal charge of −1. This charge results from a combination formal charge in which each of the three oxygens carries a − charge, whereas the nitrogen carries a +1 charge, all these adding up to formal charge of the polyatomic nitrate ion. This arrangement is commonly used as an example of resonance. Like the isoelectronic carbonate ion, the nitrate ion can be represented by resonance structures: Dietary nitrate A rich source of inorganic nitrate in the human diets come from leafy green foods, ...

Confidence Hills
The Confidence Hills are a mountain range in the Mojave Desert, in southern Inyo County, California California is a state in the Western United States, located along the Pacific Coast. With nearly 39.2million residents across a total area of approximately , it is the most populous U.S. state and the 3rd largest by area. It is also the m .... They are known as Confidence Hills for their formation of favorable flower structures, which are developed in Pliocene to recent lacustrine and alluvial sentiments. Since Pliocene times, the Death Valley has been rapidly subsiding basin. For this reason, it has been the final resting place for draining waters in the eastern slope of Sierra Nevada, the northern slopes of the Traverse ranges, the Mojave Desert, and the desert in southwestern Nevada. During these Pleistocene times, the Sierra Nevada waters have drained into lake Owens and finally into lake China and lake Searles subsequently and Lake Panamint and eventually lake Manly. ...

Mining In Chile
The mining sector in Chile is one of the pillars of Chilean economy and copper exports alone stands for more than one third of government income. Most mining in Chile is concentrated to the Norte Grande region spanning most of the Atacama Desert. Mining products of Chile includes copper, gold, silver, molybdenum, iron and coal. Chile was, in 2019, the world's largest producer of copper, iodine and rhenium, the second largest producer of lithium and molybdenum, the sixth largest producer of silver, the seventh largest producer of salt, the eighth largest producer of potash, the thirteenth producer of sulfur and the thirteenth producer of iron ore in the world. In the production of gold, between 2006 and 2017, the country produced annual quantities ranging from 35.9 tons in 2017 to 51.3 tons in 2013. Nitrate Mining nitrate in the North of Chile defined the country's history from the late 19th century to the mid 20th. Indeed the period 1873-1914 is referred to as the Saltpetre Rep ...

Niter
Niter or nitre is the mineral form of potassium nitrate, KNO3. It is a soft, white, highly soluble mineral found primarily in arid climates or cave deposits. Historically, the term ''niter'' was not well differentiated from natron, both of which have been very vaguely defined but generally refer to compounds of sodium or potassium joined with carbonate or nitrate ions. Characteristics Niter is a colorless to white mineral crystallizing in the orthorhombic crystal system. It is the mineral form of potassium nitrate, , and is soft (Mohs hardness 2), highly soluble in water, and easily fusible. Its crystal structure resembles that of aragonite, with potassium replacing calcium and nitrate replacing carbonate. It occurs in the soils of arid regions and as massive encrustations and efflorescent growths on cavern walls and ceilings where solutions containing alkali potassium and nitrate seep into the openings. It occasionally occurs as prismatic acicular crystal groups, and in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
War Of The Pacific
The War of the Pacific ( es, link=no, Guerra del Pacífico), also known as the Saltpeter War ( es, link=no, Guerra del salitre) and by multiple other names, was a war between Chile and a Bolivian–Peruvian alliance from 1879 to 1884. Fought over Chilean claims on coastal Bolivian territory in the Atacama Desert, the war ended with a Chilean victory, which gained for the country a significant amount of resource-rich territory from Peru and Bolivia. The war began over a nitrate taxation dispute between Bolivia and Chile, with Peru being drawn in due to its secret alliance with Bolivia. But historians have pointed to deeper origins of the war, such as the interest of Chile and Peru in the nitrate business, the long-standing rivalry between Chile and Peru, as well as political and economical disparities between Chile, Peru and Bolivia. On February 14, 1879, Chile's armed forces occupied the Bolivian port city of Antofagasta, subsequently war between Bolivia and Chile was decl ...

The Omnivores Dilemma
''The Omnivore's Dilemma: A Natural History of Four Meals'' is a nonfiction book written by American author Michael Pollan published in 2006. As omnivores, humans have a variety of food choices. In the book, Pollan investigates the environmental and animal welfare effects of various food choices. He suggests that, prior to modern food preservation and transportation technologies, the dilemmas caused by these options were resolved primarily by cultural influences. Technology has made foods that were previously seasonal or regional available year round and in all regions. The relationship between food and society, once moderated by culture, is now confused. To teach more about those choices, Pollan describes various food chains that end in human food: industrial food, organic food, and food we forage ourselves; from the source to a final meal, and in the process writes a critique of the American method of eating. Contents Michael Pollan informs us about how corn, the U.S's main f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haber Process
The Haber process, also called the Haber–Bosch process, is an artificial nitrogen fixation process and is the main industrial procedure for the production of ammonia today. It is named after its inventors, the German chemists Fritz Haber and Carl Bosch, who developed it in the first decade of the 20th century. The process converts atmospheric nitrogen (N2) to ammonia (NH3) by a reaction with hydrogen (H2) using a metal catalyst under high temperatures and pressures: : \ce \quad \Delta H^\circ = -91.8~\text Though this reaction is exothermic (i.e. it releases energy, albeit not very much), it results in a decrease in entropy, which is the central reason why it is very challenging to carry out. Before the development of the Haber process, it had been difficult to produce ammonia on an industrial scale, with early methods, such as the Birkeland–Eyde process and the Frank–Caro process, all highly inefficient. During World War I, the Haber process provided Germany with a s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
