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:Storage of organic chemicals in the warehouse, ventilation requirements

The use of anti-static ventilation fan ventilation.

Q:Why can organic matter be unique in chemical substances? What is the nature of the C atom?

Silicon compounds can also be made like this. However, for silicon-based organisms, the appropriate temperature of silicon-based enzymes is probably too high, the earth is too cold for them.

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

Organic compounds in addition to a few, can generally burn. Compared with inorganic matter, their thermal stability is relatively poor, the electrolyte is easy to heat decomposition. The melting point of organic matter is low, generally not more than 400 ℃. The polarity of organic matter is very weak, so most of the water is not soluble. The reaction between organic matter, mostly intermolecular reactions, often requires a certain activation energy, so the reaction is slow, often requiring catalyst and other means. And the reaction of organic matter is more complex, under the same conditions, a compound can often be several different reactions at the same time, generate different products.
