Q: Chemical life network: chemical (inorganic reaction, organic reaction) is equal to the life of life reaction?: Inorganic chemistry is the science of the composition, nature, structure and reaction of inorganic substances. It is the oldest branch of chemistry. All inorganic substances include all chemical elements and their compounds, except for most of the carbon compounds (except for carbon dioxide, Carbon monoxide, carbon disulfide, carbonates and other simple carbon compounds are still inorganic substances, the rest are organic matter.

Q: Organic organic compounds are organic matter?: Organic matter is defined as the presence of hydrocarbons and their derivatives, and the presence of covalent bonds is a feature of them.

Q: What is the relationship between hydrocarbon and hydrocarbon derivatives?: The hydrocarbon is the parent of the organic compound, and the other various organic compounds can be regarded as derivatives of one or more hydrogen atoms in the hydrocarbon molecule being replaced by atoms or radicals of other elements.

Q: Why is dry ice not organic?: Dry ice is solid. It is a simple carbonaceous compound that is not the material basis for life. Therefore, dry ice is an inorganic compound

Q: Are there two derivatives of equivalent hydrogen?: You give the scope is too broad, at least to set in what kind of functional group range ah.

Q: What is "organic" and "inorganic" in chemistry?: Carbon compounds, not carbon oxides, carbonates, bicarbonates are organic matter

Q: The aromatic hydrocarbon derivative refers to monocyclic or polycyclic: To see what is the derivative of aromatic hydrocarbons, by its own is a single ring or multi-ring decision

Q: Inorganic chemistry employment direction? Current research direction: Optical inorganic boring, and now are with rare earth elements and radioactive elements to do some material research. Or electrochemical. battery!

Q: Carbon compounds (except inorganic carbon compounds), hydrocarbons and derivatives of the general term is?: Hydrocarbon it

Q: Why artemisinin and its derivatives in the molecular structure of a peroxide chain, the chemical properties are more stable?: Stable, then it will not be 60 degrees that is broken down, there is no need for rectal administration ... ...
