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:Clothes on the metal buttons and metal ornaments for a long time there will be a layer of oxide, looks bleak, what good way to make these metal accessories smooth shiny?

Scrub with toothpaste, very effective oh ...

Q:Iron oxides and their properties

There is iron oxide, is iron oxide Fe2O3, reddish brown powder, commonly known as iron red, it can be used as paint pigments

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.

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

While KMnO4 KClO3 contains oxygen but not an oxide.

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
