The kinds of living organisms currently known on Earth all use carbon compounds for basic structural and metabolic functions, water as a solvent, and DNA or RNA to define and control their form. They have a defined formula and consistent structure. For example, the salt ammonium sulfate consists of the cation NH 4 + and the sulfate anion SO 4 Oxyanions are formed by a large majority of the chemical elements. Nickel is classified as a transition metal with nickel(II) having much chemical behaviour in common with iron(II) and cobalt(II). An oxyanion, or oxoanion, is an ion with the generic formula A x O z y (where A represents a chemical element and O represents an oxygen atom).

The arsenate ion is As O 3 4.An arsenate (compound) is any compound that contains this ion. It is an obsolete insecticide, now prohibited in the western world, but only after many thousands of tonnes had been produced and used. It was first isolated in 1899 from the dyer's broom, Genista tinctoria; hence, the chemical name.The compound structure was established in 1926, when it was found to be Hypothetical types of biochemistry are forms of biochemistry agreed to be scientifically viable but not proven to exist at this time.

Chemical characteristics of the arsenic trioxide As 2 O 3 make it a good candidate for a standard substance in many potentiometric methods, however, because of its toxicity it is used less and less frequently. For example, sodium chloride is a crystal. Chemical Abstracts Service No. Arsenic occurs in many minerals, usually in combination with sulfur and metals, but also as a pure elemental crystal.Arsenic is a metalloid.It has various allotropes, but only the gray form, which has a metallic appearance, is important to industry.. Not reactive when mixed with water. 8 1 4 A: Calculating the total number of valence electron in BH3: Arsenic trioxide, sold under the brand name Trisenox among others, is an inorganic compound and medication. If life exists on other planets or moons it may be The effectiveness of sodium fluoroacetate as a rodenticide was reported in 1942. Arsenite can adsorb or coprecipitate with metal sulfides and has a high affinity for other sulfur compounds. Cas. Cadmium chloride is used in electroplating, printing, photocopying, dyeing, mirrors, vacuum tubes, lubricants, analytical chemistry and as a chemical intermediate to produce cadmium containing pigments and stabilizers. Sodium fluoroacetate is an organofluorine chemical compound with the formula FCH 2 CO 2 Na. As a medication, it is used to treat a type of cancer known as acute promyelocytic leukemia.
