The following process is proposed to describe the detailed interfacial reaction mechanism of the SiCl 4 reduction process from molecular point of view: a SiCl 4 molecule reduces with the release of a Cl − ion, followed by the reaction between the residual SiCl 3 − and another nearby SiCl 4 to produce the intermediate states containing Si 2 ...

Copper reduces NO-3 into NO and NO 2 depending upon the concentration of HNO 3 in solution. (Assuming fixed [Cu 2+] and P NO = P NO2), the HNO 3 concentration at which the thermodynamic tendency for reduction of NO-3 into NO and NO 2 by copper is same is 10 x M. The value of 2x is .....

This diagram details the papermaking process and illustrates the extensive use of recovered paper. New pulp, however, is an integral part of the papermaking process: recovered paper cannot be recycled indefinitely because the fibres lose their papermaking qualities. Click on the labels to find out more about each stage of the papermaking process.

The loss of electrons is called oxidation. The gain of electrons is called reduction. Because any loss of electrons by one substance must be accompanied by a gain in electrons by something else, oxidation and reduction always occur together. As such, electron-transfer reactions are also called oxidation-reduction reactions, or simply redox ...
