- Q: What is organic matter?
- Green plants use light to provide energy, in the chloroplast synthesis of starch and other organic matter, and the light energy into chemical energy stored in organic matter, this process is often said that photosynthesis.
- Q: Why the silicon hydride less, a lot of hydrocarbons. (Why did not you find silicon-based creatures) and why are so many oxides of silicon, little carbon oxides?
- You know silane bar, SiH4, this thing will be spontaneous, very unstable
- 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: Sugar, fat, and so on a variety of organic matter is full of different units of the heat of the small box. (Save the heat the most efficient, the least loss of heat the most practical and most economical box).
- The fundamental difference between organic matter and inorganic matter is whether it contains carbon elements (except carbon monoxide, carbon dioxide, carbonates, metal carbides and other simple carbon compounds). Is the carbon-based life (that is, we) the division of life material and non-life material academic concept. Regardless of whether or not to store heat. The ability of many inorganic materials to store heat is much higher than that of organic matter. From a broad cosmic perspective. Organic and inorganic division does not make sense, assuming that there is a silicon-based life (this possibility is very high). Then their organic and inorganic division should lie in whether it contains silicon.
- Q: The functional group of the derivative of the hydrocarbon
- Common functional groups are: carbon-carbon double bond, -OH-COOH-CHO-NH2, often react, replace (including halogenation, nitration, sulfonation, esterification, hydrolysis, etc.), addition, elimination, addition polymerization , Organic matter oxidation and reduction, color and so on.
- 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?
- The traditional FT synthesis method of the product of heavy hydrocarbon content is high, the composition is complex, so the combustion efficiency is not optimistic. Germany is in view of the supply of oil is less than consumption (loss of production areas and lack of refined production capacity) was forced to take the FT technology to add (Germany's local coal reserves larger). So the FT fuel in the World War II Germany's energy system accounted for little, the specific data is still controversial, there are 15% and 25% said.
- Q: What are the derivatives of hydrocarbons?
- Including alcohols, acids, aldehydes, ethers, esters, halogenated hydrocarbons and the like
- Q: What is "organic" and "inorganic" in chemistry?
- Carbon-free substances or carbon oxides, carbonates, bicarbonates are organic matter
- 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: Carbon compounds (except inorganic carbon compounds), hydrocarbons and derivatives of the general term is?
- Hydrocarbons and hydrocarbon derivatives
