Chlorine forms compounds with the other halogens and with oxygen; when chlorine is the more electronegative element in the compound, the compound is called a chloride. The salts of hydrochloric acid contain chloride ions and can also be called chlorides. The word chloride can also refer to a chemical compound in which one or more chlorine atoms are covalently bonded in the molecule.

The nearby Ertsberg East Skarn (ca. 2.6 Ma; Pollard et al., 2005) is a calcium–magnesium silie skarn hosted by carbonates of the Tertiary Waripi and Faumai Formations (Mertig et al., 1994). Magnetite of igneous and hydrothermal origin is a widespread accessory to major mineral phase in the intrusive rocks and hydrothermal veins, as well as
Eggplant, Solanum melongena, is a tropical, herbaceous, perennial plant, closely related to tomato, in the family Solanaceae which is grown for its edible fruit.The plants has a branching stem and simple, long, flat. coarsely lobed leaves which are green in color and are arranged alternately on the branches.

Hard water is a common quality of water which contains dissolved compounds of calcium and magnesium and, sometimes, other divalent and trivalent metallic elements. Dissolved calcium and magnesium salts are primarily responsible for most scaling in pipes and water heaters and cause numerous problems in laundry, kitchen, and bath.
This focus led to her organizing her university work and her speeches and writings around two interrelating themes: (1) the cultural framework that influences the eduion of children and youth in time-place; and (2) the definition of physical eduion as a name, as a profession, and as an academic body of knowledge.

Mercury occurs naturally in the environment and exists in a large nuer of forms. Like lead or cadmium, mercury is a constituent element of the earth, a heavy metal.In pure form, it is known alternatively as "elemental" or "metallic" mercury (also expressed as Hg(0) or Hg 0).Mercury is rarely found in nature as the pure, liquid metal, but rather within compounds and inorganic salts.
The Occupational Safety and Health Administration (OSHA) proposes to amend its existing standard for employee exposure to hexavalent chromium (Cr(VI)). The basis for issuance of this proposal is a preliminary determination by the Assistant Secretary that employees exposed to Cr(VI) face a

Calcium is a malleable, ductile, silver-white, relatively soft metal with face-centered, cubic crystalline structure. Chemically it reseles strontium and barium; it is classed with them as an alkaline-earth metal alkaline-earth metals, metals constituting Group 2 of the periodic table.
The sulfite process produces wood pulp which is almost pure cellulose fibers by using various salts of sulfurous acid to extract the lignin from wood chips in large pressure vessels called digesters. The salts used in the pulping process are either sulfites (SO 3 2−), or bisulfites (HSO 3 −), depending on the pH.The counter ion can be sodium (Na +), calcium (Ca 2+), potassium (K

Elemental mercury dissolves in the blood upon inhalation, and some remains unchanged (Magos, 1967). Elemental mercury in the blood is oxidized to its divalent form in the red blood cells (Halbach & Clarkson, 1978). The divalent ion exists as a diffusible or non-diffusible form.
Calcium is the antagonist of magnesium in the organism. Disruption of the magnesium-calcium balance is observed in cases of rickets, when magnesium passes from the blood into the bones, displacing the calcium in them. Deficiency of magnesium salts in the diet disrupts muscle contraction and the normal excitability of the nervous system.
