- Q: The role of sugar in the human body?
- Saving protein: We all know that the energy required by the body is mainly supplied by glycogen, and if the glycogen is sufficient, it will not lead to protein breakdown, and if the body's sugar is lacking, the protein will decompose for energy, so that the protein in the body will be lost.
- Q: Is carbon monoxide an organic gas?
- The organic compound contains carbon, hydrogen, oxygen, nitrogen and other elements, a few also contain sulfur, phosphorus, halogen, etc. Any kind of organic compounds, its molecular composition contains carbon, the vast majority also contains hydrogen Elements. Since the hydrogen atoms of the organic compound molecules can be replaced by other atoms or radicals, resulting in a lot of other organic compounds, so modern people generally believe that hydrocarbons and their derivatives known as organic compounds, referred to as organic matter.
- Q: Compare the difference between London smoke and Los Angeles photochemical smog
- Los Angeles photochemical smog nitrogen content and hydrocarbons and derivatives more, mainly close to the car exhaust. Foggy London situation related to coal, soot solid particles and sulfur oxide more. Foggy London is more bleak, and Los Angeles is more toxic.
- Q: High school chemical hydrocarbons with hydrocarbon derivatives with water solubility, density for accurate and comprehensive summary, thank you. Out of college entrance examination
- Hydrocarbons are insoluble in water and have a lower density than water
- 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 FT synthesis method is a coal liquefaction technique under an iron-based catalyst (conventional FT method is a cobalt-based catalyst). Mainly syngas (CO and H2-based) saturated alkylation technology.
- Q: What are the oxygen consumption of the oxygen-containing derivatives of the mass hydrocarbons?
- For this comparison, you can see the experimental formula of this material, a C corresponds to an oxygen, 4 H corresponds to an oxygen, the experimental consumption of oxygen up, then under the same quality conditions, the greater the oxygen consumption of this material
- Q: Artemisinin is not a derivative of hydrocarbons
- Artemisinin is a colorless needle-like crystal obtained from the compound inflorescences Artemisia annua L., which is (3R, 5aS, 6R, 8aS, 9R, 12S, 12aR ) - octahydro-3,6,9-trimethyl-3,12-oxo-12H-pyran [4,3-j] -1,2-benzodiazepine-10 (3H) -one. Molecular formula for the C15H22O5.
- 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: Is the system name of a hydrocarbon derivative named if the question can be named according to the nomenclature of the alkane?
- No, aldehyde is functional group, must be aldehyde for the mother. In addition, when the aldehyde group is a substituent, it is named as a formyl group.
