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: Such as the problem, and how, how to squeeze methane into liquid, or how to squeeze into the liquid gas? It is still very difficult ... there is a dangerous thing .... (this is not important) high reward: 1. A hydrocarbon containing five to eight carbons 2. Not, it is an oxygen-containing derivative of a hydrocarbon 3. A hydrocarbon and a halogenated hydrocarbon (unsaturated) polymer, an alcohol, a phenol and

Q: What is the proportion of hydrocarbons synthesized by Fischer-Tropsch Synthese in liquid fuels consumed by Nazi Germany? What are the proportions of these hydrocarbons as an industrial raw material into their military industry, in addition to fuel? At that time, did the Fischer-Tropsch preparations occupy an important position in Nazi Germany's military industry or heavy industry?: Now, the improved economic benefits of FT still limit its further development. Some of the enterprises' coal indirect liquefaction projects have been terminated (for example, Shenhua Group), coupled with the impact of breakthrough development of shale oil technology, the development prospect of coal indirect liquefaction not optimistic.

Q: What is the difference between organic matter and inorganic matter?: Inorganic matter is an inorganic compound. Generally refers to the elements other than carbon elements, such as water, salt, sulfuric acid, lime and so on. However, some simple carbon compounds such as carbon monoxide, carbon dioxide, carbonates, carbonates and carbides, because of their composition and properties and inorganic similar, so also as an inorganic to study. The vast majority of inorganic matter can be classified as oxides, acids, alkalis and salts.

Q: What is the definition of organic matter: Organic matter usually refers to carbon-containing compounds, or hydrocarbons and their derivatives are collectively referred to as organic compounds.

Q: Are hydrocarbons all organic?: A series of organic compounds, also known as "hydrocarbons." Many types, according to the structure and nature,

Q: Is the heterocyclic compound not a derivative of cyclic hydrocarbons? why?: The heterocyclic compound is an organic compound containing a heterocyclic structure in its molecule. The atoms that make up the ring contain at least one heteroatom in addition to carbon atoms. The heteroatoms include oxygen, sulfur, nitrogen and the like. Theoretically, the heterocyclic compound can be regarded as a derivative of benzene, that is, one or more CH in the benzene ring is replaced by a heteroatom. The heterocyclic compound may be in parallel with the benzene ring to form a fused ring heterocyclic compound.

Q: NH4HCO3 and so have C atoms ah, why still inorganic: Not all carbon compounds are organic compounds, CO, CO2, carbonic acid, carbonates (including salt and acid salts), metal carbides, cyanides, thiocyanates are inorganic compounds.

Q: Is grease a polymer compound? Is it a derivative of saturated hydrocarbons?: Although the relative molecular mass of oil is large, but does not belong to the polymer compound, the polymer compound should refer to a chain with a base number n of the material. Nor is it a derivative of saturated hydrocarbons. The oil is a non-saturated tallow fatty acid glyceride, and the fat is a saturated glycerol ester of saturated higher fatty acids. The more the double bond, the lower the boiling point

Q: Why can organic matter be unique in chemical substances? What is the nature of the C atom?: To give a reason, the current production of more economical temperature control is limited.
