- Q:Whether the metal oxides are alkaline oxides
- But the metal oxides are not all alkaline oxides
- 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:What are the oxides of chlorine
- Dichloride, also known as chlorate (ClOClO3) hexahydrate (Cl2O6) dioxane (Cl2O7)
- Q:What is the largest oxide of oxygen content?
- [Oxygen content of the largest oxide] is hydrogen peroxide, the formula: H2O2; oxygen content of the mass fraction of 94.1%.
- Q:Is the oxide pure?
- The same element of oxide is not necessarily pure, such as sulfur dioxide, sulfur trioxide. The The
- Q:What is salt oxide, what is not salt oxide?
- The salt oxide is the oxide and the corresponding acid and acid ions
- 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.
- Note: 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.
- 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.
