- 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: 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 salt oxide, what is not salt oxide?
- And acid and alkali reaction is only salt is generated salt oxide
- Q: Oxide and organic peroxide signs
- Broad oxide (oxide) refers to the oxygen element and another chemical composition of the binary compounds, such as carbon dioxide (CO?), Calcium oxide (CaO) and so on. But the combination of oxygen and electronegativity with greater fluoride is generally referred to as fluoride rather than oxide.
- Q: Whether the metal oxides are alkaline oxides
- Such as aluminum oxide, both with the acid reaction, but also and alkali reaction, is an amphoteric oxide
- 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 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.
- 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.
- Acid oxide corresponding to the hydrate is acid, such as CO2 corresponding to the hydrate is H2CO3, N2O5 corresponding hydrate is HNO3.
- Q: Titanium oxide total of several?
- Ti2O3 titanium dioxide purple powder, hexagonal crystal structure, lattice constant α = 0.5155nm. Containing oxygen 59.5% ~ 60.8% (at). Density 4.486g / cm3. Melting point 1900 ℃. Soluble in 40% Hydrofluoric acid, can be concentrated nitric acid erosion, but not concentrated hydrochloric acid, concentrated sulfuric acid erosion, nor for alkali erosion, and 30% (mass) hydrogen peroxide solution to produce a slightly yellow solution. ~ 300 ℃ into titanium pentoxide. Vacuum in 1600 ℃ heated titanium powder and titanium dioxide mixture or 1500 ℃ hydrogen reduction of titanium dioxide. Titanium ion itself is an excellent reducing agent.
- 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.
