The hydrate of chlorine is of special interest as the solid phase originally thought to be solid chlorine but shown (in 1811) by Humphry Davy to contain water. It was later given the formula CI2. 10 H2O by Michael Faraday. The unit cell of this (cubic) structure (a 12 A) contains 46 H2O which form a framework (Fig. 15.6) in which there are 2 dodecahedral voids and 6 rather larger ones (14-hedra). If all... 

Industrial ethyl alcohol can be produced synthetically from ethylene [74-85-17, as a by-product of certain industrial operations, or by the fermentation of sugar, starch, or cellulose. The synthetic route suppHes most of the industrial market in the United States. The first synthesis of ethanol from ethylene occurred in 1828 in Michael Faraday s lab in Cambridge (40). 

Capacitance — Property of a circuit element characterized by an insulating medium contained between two conductive parts. The unit of capacitance is a farad (F), named for the English scientist Michael Faraday. Capacitance values are more commonly expressed in microfarad ( iF), which is 10 of a farad. Capacitance is one means by which energy or electrical noise can couple from one electrical circuit to another. Capacitance between two conductive parts can be made infinitesimally small but may not be completely eliminated. 

Michael Faraday is best known for work in the 1820s and 1830s establishing that a moving magnetic field induces an electric potential. He built the first dynamo for electricity generation. He also discovered benzene, invented oxidation numbers, and popularized the terms electrode, anode, and cathode. The SI unit of electrical capacitance is named in his honor. 

In this equation, is a positive number without units that represents the number of moles of electrons transferred according to the balanced equation for the reaction, and F is Faraday s constant, named after Michael Faraday FIGURE 20.13) ... 

The farad is the SI unit of the capacitance of an electrical system, that is, its capacity to store electricity. It is a rather large unit as defined and is more often used as a microfarad. It is named after the English chemist and physicist Michael Faraday (1791-1867). 

Marcet had become knowledgeable in the subject by the same method she used in teaching conversation—conversations with her husband, a London physician and chemist, and friends, Berzelius, Davy, and other notables of the scientific community. In Marcet s book conversations were among a fictitious Mrs. B and her pupils Emily and Caroline. This style was evidently effective because the book went through 16 editions and an estimated l60,000 copies were sold in the United States before 1853.Its influence on Michael Faraday can be read in his own words Mrs. Marcet s Conversations on Chemistry. .. gave me my foundation in that science. ...
