Q:Oxygen is not simple

Yes. Because there is only one element of pure matter

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:Urine in the inorganic salt content is higher than the original urine

In fact, the concentration has increased

Q:Chemical formula The longest inorganic salt

The primary stage on the salt, acid salt and so on

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:What are the two kinds of prime

Metal and non-metallic metal oxides non-metallic 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:What substances can detect inorganic salts

Looks like, a lot of inorganic salt ah, this, I suggest you clear the concept of inorganic salt under you.

Q:Is sulfur simple?

Yes, the elemental sulfur is commonly known as sulfur, which is a definition.

Q:Is the inorganic salt related to the excitement

Nerve impulses are transmitted in all or no way without attenuation along the nerve fibers. The conduction velocity of the action potential varies depending on the type of the animal, the type of nerve fibers, the thickness and the temperature.
