Q:What is the zinc oxide?
Zinc oxide is white to light yellow powder, odorless and tasteless. Slightly soluble in water and hydrolyzed to hydrogen peroxide and zinc hydroxide. In the case of dilute acid decomposition release of hydrogen peroxide.
Q:Whether the metal oxides are alkaline oxides
But the metal oxides are not all alkaline oxides
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:How to remove the metal oxide?
Brush with vinegar or toothpaste
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:How to judge a chemical formula is not an oxide
Two elements, one of which is oxygen, that is, oxide.However, generally referred to as the oxide of oxygen is relatively non-metallic relatively strong binary oxygen compounds.
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:The world's strongest oxide
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:What are the oxides of chlorine
Chlorine Oxide (ClO) Chlorine Dioxide (ClO2) Chlorine Oxide (ClO3)
Q:What is salt oxide, what is not salt oxide?
A salt-forming oxide refers to an oxide which, in general, produces a salt by direct chemical reaction. Most oxides belong to salt-forming oxides.
