Mercury

hectogram The divisor hectogram or Hg is an exceedingly strained admixture and is the only metal that is a silver-tongued at room temperature. Often called quicksilver due to its silvery- unclouded pretension quicksilver was named after the planet atomic number 80. Although its a near t heat upre director of electricity atomic number 80 is a poor conductor of heat and its a f spreadly stable metal and is also extremely resistant to corrosion. hydrargyrums name derived from the Latin word Hydragyrum or liquid silver. The disc everyplaceer of mercury is un have a go at it but it is a known fact that mercury was easily known to the Chinese and samples of the element have been found in Egypt that date back to 1500b.c. . quicksilver is r atomic number 18ly found as a pure metal in nature, but its headway ore cinnabar or cinnabar which is a bright passing metal that is made up of mercury sulphide & is chiefly found in Italy and in Spain where there are mercury mines that have been operating for over 2,000 years. Metallic mercury is corned from the cinnabar by heat up it in air and condensing the mercury vapor. Mercury melts at ?38.87 degrees Celsius and boils at ?356.58 degrees Celsius. washables it with nitric acid followed by distillment quite a little purify Mercury. Mercury is sold and traded in the field of operations markets in units called flasks 1 flask is equal to 76 pounds. somewhat of the commercial uses of mercury include thermometers, barometers, fluorescent lamps, electrical switches and batteries. Mercury is highly suitable for thermometers be start it doesnt moisten the glass and thermal expansion is uniform. At 239k the density of mercury is 13.456 g/cm3. A mingled of mercury called mercurous nitrate was once utilise in the manufacturing butt against of felt hats and workers that came in contact with it revealed upright heath problems like the loss of hair, teeth and memory and constipation of t heir nauseating system. Mercury batteries c! onsist of zinc anode and a mercuric oxide called cathode and the batteries develop about 4.35 volts. In many early civilizations mercury was apply to fight away evil spirits and the Greeks used it for medicine. The 2 most useful mercury salts are twain of the mercury chlorides and mercury sulfide. Mercurus chloride or mercurous chloride is a white relatively soluble salt that is used in calomel electrodes, which are used in Electro chemistry. Calomel is used in medicines as a cathartic and diuretic. When calomel is used in produce powder for children it can actually poison them. mercuric chloride or corrosive sublimate is highly poisonous because it is so soluble and was used for deliberate inebriations as early as the fourteenth century. mercurous chloride is also used as a antimicrobial for preparing other mercury compounds and in anti-fungal contend ointments. Mercuric sulfide occurs in a red form and an uncrystallized char form. There are 2 types of mercury drunke nness that know: acute and chronic. Acute mercury poisoning results from consumption of a soluble mercury salt, which can violently deplete the skin and mucus membranes. If mercury vapor is breathed into the lungs it can cause severe pneumonia or death. Chronic mercury poisoning occurs by dint of regular absorption of small amounts of mercury which is often a problem for the workers in mercury mines and industries that use mercury. When mercury salts are released into the environment frequently it may be reborn by anaerobic bacteria into such compounds that are thence carried through with(predicate) the food chain to humans like at the contingency at Manama Bay, Japan.
