Q:What are the black solid elements in junior high school chemistry?

Black solid Element: Toner, iron powder

Q:What is the important character of Chinese made alkali?

In 1862, the Belgian people Solvay (Ernest Solvay 1838-1922) invented the salt, ammonia, carbon dioxide as raw material for the production of sodium carbonate "Solvay alkali method" (also known as the ammonia method). Since then, Britain, France, Germany, the United States and other countries have established a large-scale production of soda ash plant, and organized the Saul Wei Association, members of the country outside the implementation of technical blockade.

Q:Seaweed, kelp, shrimp and other seafood, the content is more of the kind of inorganic salts

Inorganic salts in the human body is very small, but the role is very large, if the lack of suffering from the corresponding diseases, such as iodine deficiency susceptible to big neck disease, kelp, seaweed and shrimp and other seafood iodine is rich; More calcium; spinach rich in iron; nuts, liver and other zinc more.

Q:What is the composition of inorganic salts?

Inorganic salts are mineral nutrients that are present in the body and in food

Q:What is the elemental element

Should be a simple element and element it Elemental matter must be pure matter composed of the same element, the mixture can not be simple. An element is called a free state of an element in the presence of an element. The element is the general term for the same class of atoms with the same number of nuclear charges (protons)

Q:What is the element?

A substance consisting of atoms of an element that is more stable in free form. Such as oxygen (O 2), chlorine (Cl 2), sulfur (S), iron (Fe), and the like. Elementary and element are two different concepts. The elements are collectively referred to as atoms having the same number of nuclear charges (protons). An element may have several elements, such as oxygen (O 2), ozone (O3) tetramerox (O4, a new type of oxygen molecules synthesized by a scientist in Italy). Although any of these substances are simple, because they are pure elements of the same element, but oxygen and ozone together is not pure, they are the same kind of elements of the mixture.

Q:What is the difference between organic salt and inorganic salt?

one is organic while the other is inorganic

Q:and what are the kinds of organic compounds?..pls. help me abt. this..thanks!..(^_^)

I think organic compunds are anything with Carbon(C), although I really don't know.

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.

Q:Can you please help me with this question and give me a website reference.

Many of these materials enter the water through natural channels---minerals, salts and the like come from exposure to rocks, dirt and other inorganic materials.
