2020-8-7 · Redox (reduction–oxidation, pronunciation: / ˈ r ɛ d ɒ k s / redoks or / ˈ r iː d ɒ k s / reedoks) is a type of chemical reaction in which the oxidation states of atoms are changed. Redox reactions are characterized by the actual or formal transfer of electrons between chemical species, most often with one species (the reducing agent) undergoing oxidation (losing electrons) while
2020-8-9 · Carbon (from Latin: carbo "coal") is a chemical element with the syol C and atomic nuer 6. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds.It belongs to group 14 of the periodic table. Carbon makes up only about 0.025 percent of Earth’s crust. Three isotopes occur naturally, 12 C and 13 C being stable, while 14 C is a radionuclide
Carbon monoxide, extracted through metallurgical process, is used as a reducing agent to obtain many elements and compounds. Vegetal carbon, which is an amorphous form of carbon, is utilized as a bleaching agent and a gas absorbent. Carbon is used in the rim of automobiles as a black fume pigment.
