Silicon s tetravalent pyramid crystalline structure, similar to tetravalent carbon, results in a great variety of compounds with many practical uses. Crystals of sihcon that have been contaminated with impurities (arsenic or boron) are used as semiconductors in the computer and electronics industries. Silicon semiconductors made possible the invention of transistors at the Bell Labs in 1947. Transistors use layers of crystals that regulate the flow of electric current. Over the past half-century, transistors have replaced the vacuum tubes in radios, TVs, and other electronic equipment that reduces both the devices size and the heat produced by the electronic devices. 

IL Freshly precipitated, thoroughly washed FesOa aq. is added to carbonate-free 50% NaOH. An amount of NaOH equal in weight to the water contained in the FesOa paste is then added and the latter is dissolved with moderate heating (not to exceed 60 °C). The mixture, in a silver Erlenmeyer flask protected with a Peligot tube (filled with 50% KOH), is allowed to stand for several days in an electric drying oven at 70°C. In this manner, the FesOa aq. is completely converted into the nearly colorless, microcrystalline Na4[Fe(OH)7] 2 HsO, which is sparingly soluble in concentrated NaOH. 

A decomposition reaction is the opposite of a combination reaction. An example of a decomposition reaction in which a compound decomposes to form the elements in it is provided by the manufacture of carbon black. This material is a finely divided form of pure carbon, C, and is used as a filler in rubber tire manufacture and as an ingredient in the paste used to fill electrical dry cells. It is made by heating methane (natural gas) to temperatures in the range of 1260-1425°C in a special furnace, causing the following reaction to occur ...
