Q:What is the oxide

? Oxide belongs to the compound, it must be pure, its composition contains only two elements, one of which must be oxygen, and the other if the metal element, compared to metal oxide; if non-metallic, Metal oxide

Q:Oxide and organic peroxide signs

An organic compound containing -O-O-peroxy functional group formed by replacing hydrogen atoms in hydrogen peroxide with an organic group such as an alkyl group, an acyl group, an aromatic group or the like. Characterized by heating more than a certain temperature will decompose to produce oxygen free radicals, unstable, easy to break down. Chemical production of organic peroxides is mainly used for synthetic resin polymerization initiator, catalyst. In the field of polymer materials, it can be used as a radical polymerization initiator, graft reaction initiator, rubber and plastic cross-linking agent, unsaturated polyester curing agent and spinning grade polypropylene in the preparation of molecular weight and Molecular weight distribution regulator. Environmental pollution in the air under the action of light through the free radical reaction can produce peroxy nitrates compounds, photochemical oxidants in one of the species. On the skin, eyes, mucous membrane has a strong irritant, is an important pollutant in the atmosphere. Such substances are flammable and explosive dangerous goods, the use should pay attention to safety. Generally, the active oxygen content, activation energy, half-life and decomposition temperature were used as the basis of selection.

Q:What is called transition metal oxide doping

Transition element refers to a series of metal elements in the d-region of the periodic table, also known as transition metal, including chromium, manganese, iron, cobalt, nickel, copper, zinc and so on are transition metals.

Q:Do not say fluorine gas, it is the strongest element, do not say that electronic anti-matter and current, authority ah

Chlorofluorinated Chloride C1F5 Chlorinated Fluorinated Chloride is a non-combustible, non-combustible colorless gas with strong irritating odor at room temperature. Its solid state is white and has a pale yellow color. It is rapidly hydrolyzed to form chlorine and hydrofluoric acid It is a strong oxidizing agent that reacts strongly with most of the inorganic matter, so that although it does not burn in the air, it can cause fire and explosion.
