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:What is the zinc oxide?: Zinc oxide is an oxide of zinc. Hard to dissolve in water, soluble in acid and alkali. Zinc oxide is a commonly used chemical additive, widely used in plastic, silicate products, synthetic rubber, lubricants, paint coatings, ointment, adhesives, food, batteries, flame retardants and other products in the production. Zinc oxide band gap and exciton greater binding capacity, high transparency, excellent room temperature luminescence performance in the semiconductor field of liquid crystal display, thin film transistors, light-emitting diodes and other products are used. In addition, the micro-particles of zinc oxide as a nano-materials also began to play a role in related areas.

Q:Iron oxides and their properties: Three, you can search the book, the book is very comprehensive, more to see the book friend benefits

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:Acidic oxide is a kind of oxide which can form acid or react with water to form salt and water. Generally non-metallic elements of oxides and certain transition metal elements of high-priced oxide. Such as sulfur trioxide SO3, phosphorus pentoxide P2O5, manganese dioxide Mn2O7, chromium trioxide CrO3 and so on. Most of the non-metallic oxides are acidic oxides. In our familiar non-metallic oxides, carbon monoxide and nitric oxide are not acidic oxides, and are usually classified as non-acid oxides.: The corresponding hydrate of the basic oxide is a base. For example, CaO corresponding to the hydrate is Ca (OH) 2, Fe2O3 corresponding to the hydrate is Fe (OH) 3.

Q:What is called transition metal oxide doping: The so-called dopant oxide is doped with impurities in oxides, such as the incorporation of trivalent Al in ZnO, and the doping of oxides can affect and alter the original properties.

Q:How to judge a chemical formula is not an oxide: Oxide Definition: consists of two elements, one of which is a compound of oxygen, such as CO2 Fe2O3, H2O

Q:What is salt oxide, what is not salt oxide?: Can not react with acid or alkali to produce the corresponding price of salt and water oxide is called non-salt oxide.

Q:Is SiO2 an amphoteric oxide?: Not though SiO2 reacts with HF but the reason for this reaction is not because H + is because Si and F-coordination generated SiF4 is very stable.

Q:Is the oxide pure?: Pure substances are divided into simple substances and compounds, oxides belong to the compound, naturally belong to the pure material
