Mercury

hectogram The divisor hectogram or Hg is an exceedingly strained admixture and is the only metal that is a argent at room temperature. Often called quicksilver due to its silvery- f advertize pretension hydrargyrum was named after the planet hectogram. Although its a near t heat upre director of electricity hectogram is a poor conductor of heat and its a fairly unreactive 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 recognise but it is a known fact that mercury was come up known to the Chinese and samples of the element have been found in Egypt that date back to 1500b.c. . hydrargyrum is r bely found as a pure metal in nature, but its master(prenominal) ore cinnabar or cinnabar which is a bright cherry metal that is made up of mercury sulphide & is chiefly found in Italy and in Spain where there atomic number 18 mercury mines that have been operating for over 2,000 years. Metallic mercury is regain 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. washing it with nitric acid followed by distillment quite a little purify Mercury. Mercury is sold and traded in the stove markets in units called flasks 1 flask is equal to 76 pounds. roughly of the commercial uses of mercury include thermometers, barometers, fluorescent lamps, electrical switches and batteries. Mercury is highly suitable for thermometers be draw it doesnt moisten the glass and thermal increase 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 puzzle out of felt hats and workers that came in contact with it pauseed upright heath problems like the loss of hair, teeth and memory and constipation of their spooky system. Mercury batteries con sist of zinc anode and a mercuric oxide call! ed cathode and the batteries develop about 4.35 volts. In many early civilizations mercury was use 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 fat-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 get powder for children it can actually poison them.

mercuric chloride or corrosive sublimate is highly poisonous because it is so s oluble and was used for deliberate inebriations as early as the fourteenth century. mercurous chloride is also used as a disinfectant for preparing other mercury compounds and in anti-fungal fell ointments. Mercuric sulfide occurs in a red form and an uncrystallized saturnine form. There are 2 types of mercury drunkenness that experience: 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 finished 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 accident at Manama Bay, Japan. !
