The halide bulbs salts are binary compounds formed of a metal and a nonmetal, without any other element. These salts are formed by the neutralization reaction between a hydric acid with a base. For example: the reaction between hydrochloric acid (HCl) with sodium hydroxide (NaOH) to form sodium chloride (NaCl). Haloidal salts are also formed

A  pi (π) bond is a type of covalent bond characterized by preventing the free rotation movement of atoms and by originating between a pair of pure-type atomic orbitals, among other peculiarities. There are bonds that can be formed between atoms by their electrons, which allow them to assemble larger and more complex structures: molecules.

The plating is a technique used in metal electrodeposition coating an electrode to create on this surface with different characteristics to those of the metal in its pure state. Plating and dipping processes are also used in electroplating, which do not involve the use of an electrical current. Electroplating, a technique used in electroplating, consists

The ferric sulfate, iron sulfate (III) , vitriol or copperas mars Mars, is an inorganic compound of formula Fe 2 (SO4) 3 . Each iron atom has three ionic bonds with sulfate. Ferric sulfate is found in a wide variety of minerals, mainly in the minerals pyrite and marcasite, where ferrous sulfate is connected with

The calcium bicarbonate is an inorganic salt with chemical formula Ca (HCO 3 ) 2 . It originates in nature from the calcium carbonate present in limestone stones and minerals such as calcite. Calcium bicarbonate is more soluble in water than calcium carbonate. This characteristic has allowed the formation of karst systems in limestone rocks

The silver chromate is a chemical compound of formula Ag 2 CrO 4 . It is one of the compounds of chromium in oxidation state (VI) and is said to be the forerunner of modern photography. The preparation of the compound is simple. This is produced by an exchange reaction with a soluble silver salt,

Addition polymers are all those that are formed through the successive and directed growth of their molecular structures. Its synthesis or manufacturing processes are based on chain growth reaction mechanisms, or on polyadditions. The best way to differentiate this type of polymer from condensation polymers is that they do not originate any molecule as a

The polylactic acid, whose correct name is poly (lactic acid), is a material formed by polymerizing lactic acid. It is also known as poly-lactide, as it can be obtained from the breakdown and polymerization of lactide, which is a dimer of lactic acid. Poly (lactic acid) or PLA is not an acid, it is a

The ice floats in the water  because of its density. Ice is the solid state of water. This state has well-defined structure, shape and volumes. Normally the density of a solid is greater than that of a liquid, but the opposite is the case for water. At normal pressure conditions (one atmosphere ), ice begins

The zinc nitrate is an inorganic compound consisting of the elements zinc (Zn), nitrogen (N) and oxygen (O). The oxidation state of zinc is +2, that of nitrogen is +5, and that of oxygen is -2. Its chemical formula is Zn (NO 3 ) 2 . It is a colorless crystalline solid that tends to
