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 the largest oxide of oxygen content?

[Hydrogen peroxide] pure hydrogen peroxide is a light blue viscous liquid, can be any proportion of mixed with water, is a strong oxidant, aqueous solution commonly known as hydrogen peroxide, colorless transparent liquid. The aqueous solution for medical wound disinfection and environmental disinfection and food disinfection. Under normal circumstances will be broken down into water and oxygen, but the decomposition rate is extremely slow, speed up its reaction rate is to join the catalyst - manganese dioxide or with short-wave radiation.

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:What is the zinc oxide?

Zinc oxide (ZnO), only this one, zinc and oxygen reaction zinc was only +2 price, oxygen-2 price

Q:Titanium oxide total of several?

TiO2 titanium oxide - titanium dioxide, is the white powder, is the best white pigment, commonly known as titanium dioxide. Previously, people mining titanium, the main purpose is to get titanium dioxide. Titanium white adhesion is strong, not easy to play It is used to make refractory glass, glaze, enamel, clay, high temperature resistant laboratory utensils, etc .. Titanium dioxide is the world's most white Of the material, l grams of titanium dioxide can be more than 450 square centimeters of the area painted white.It is more than the commonly used white pigment - zinc barium white also white 5 times, it is the best paint to paint white paint. The world as a pigment Of titanium dioxide, more than a year to several hundred thousand tons of titanium dioxide can be added to the paper, the paper white and opaque, the effect is 10 times larger than other substances, so the paper and art paper will add titanium dioxide.In addition, In order to make the color of the plastic lighter, so that artificial silk gloss soft, and sometimes to add titanium dioxide in the rubber industry, titanium dioxide is also used as a white rubber filler.

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.

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.

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

Oxygen is a colorless, almost odorless highly toxic gas, liquefied after the pale yellow. Because of the oxygen at room temperature with the dry air can react quickly to produce nitrogen dioxide and moldy colorless Gas nitrogen trifluoride (fluorine gas at room temperature with the dry air almost no reaction, which can be seen in the oxidation of tungsten fluoride), so usually see the fluoride is a brown odor of brown gas.

Q:How to judge a chemical formula is not an oxide

While KMnO4 KClO3 contains oxygen but not an oxide.

Q:What is the oxide

Elements and oxygen compounds are called oxides (and only two elements). Such as carbon dioxide (CO2), calcium oxide (CaO) Depending on the chemical nature of the oxide, the oxide according to whether the formation of salt with water and the type of salt can be divided into acidic oxides, alkaline oxides, amphoteric oxides and non-salt oxides [1] four categories. There are also many complex oxides.
