- Q: What is carbohydrate? What is organic? What is it?
- Most organic compounds mainly contain carbon, hydrogen two elements, in addition often contain oxygen, nitrogen, sulfur, halogen, phosphorus and so on. Part of the organic matter from the plant sector, but the vast majority of oil, natural gas, coal as raw materials, through artificial synthesis method. Compared with inorganic substances, the number of organic matter, up to several million kinds. The carbon atoms of the organic compound have a very strong ability to bind to each other to form a carbon or carbocyclic ring. The number of carbon atoms can be 1,2, it can be thousands, tens of thousands, many organic polymer compounds can even have hundreds of thousands of carbon atoms. In addition, the isotopic phenomenon of organic compounds is very common, which is one of the reasons for the many organic compounds. 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.
- Q: What is the difference between an aromatic compound and a hydrocarbon derivative?
- The aromatic compound is a benzene ring containing compound, which may be a hydrocarbon or a hydrocarbon derivative. Hydrocarbons are hydrocarbon-containing compounds, and hydrocarbons containing hydrocarbons other than hydrocarbons are derivatives of hydrocarbons. The two concepts have crossed.
- 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: What is the hydrocarbon thing
- Hydrocarbon, which is composed of two elements, consists of carbon and hydrogen. It is called a hydrocarbon and a hydrocarbon, which reacts with chlorine, bromine vapor, oxygen and so on. It does not react with strong acid, strong base, strong oxidizer (Such as: potassium permanganate) reaction, such as methane and chlorine in the light conditions of reaction to produce methyl chloride, dichloromethane, chloroform (chloroform) and tetrachloromethane (carbon tetrachloride) and other derivatives in the Hydrocarbon molecules in the carbon atoms connected to each other to form a carbon chain or carbon ring molecular skeleton, a certain number of hydrogen atoms attached to the carbon atoms, so that each carbon atom to maintain the price of the type of hydrocarbon is very much, the structure of known hydrocarbons More than 2,000 hydrocarbons are the parent of an organic compound. Other organic compounds can be seen as derivatives of one or more hydrogen atoms in the hydrocarbon molecule that are replaced by atoms or radicals of other elements. Word, is the use of "carbon" consonant with "hydrogen" vowel synthesis of a word, with "carbon" and "hydrogen" the composition of the internal structure of the word, the hydrocarbon is the parent of all organic compounds can be said that all Organic compounds are nothing but the result of replacing some of the atoms in the hydrocarbons with other atoms.
- Q: Are the asphalt and peat kinds of vegetables have heavy metal?
- Asphalt is a hydrophobic material, it is impermeable, and almost insoluble in water, acetone, ether, dilute ethanol, dissolved in carbon disulfide, carbon tetrachloride, sodium hydroxide.
- Q: Are all carbon compounds all organic?
- No, carbon dioxide and carbonates, bicarbonate is not it
- 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 is the difference between hot and cold asphalt?
- Cold mixed high-strength asphalt concrete, by adding asphalt in the thermosetting resin, coupled with the right amount of solvent to form a semi-flow asphalt binder, and the appropriate mix of aggregate from the asphalt concrete mixture. This asphalt concrete is a very high strength of 60 ℃, 30mm Marshall stability of 30000N, flow 20-30 (1 / 10mm), the stability of ordinary asphalt concrete is about 3 times, with good rutting resistance. Hot asphalt is composed of different molecular weight hydrocarbons and non-metallic derivatives of dark brown complex mixture, is a high viscosity organic liquid, was liquid, the surface was black, soluble in carbon disulfide. Asphalt is a waterproof moisture and corrosion of organic cementitious materials. Asphalt can be divided into coal tar pitch, petroleum asphalt and natural asphalt three: Among them, coal tar pitch is a by-product of coking. Petroleum asphalt is the residue after distillation of crude oil. Natural asphalt is stored in the ground, and some of the formation of ore or in the crustal surface accumulation. Asphalt is mainly used for coatings, plastics, rubber and other industries and pavement and so on.
- Q: What cells are composed of compounds
- The organic matter that constitutes the cell generally refers to the general term for carbon-containing compounds or hydrocarbons and their derivatives. In nature, the types of organic matter are extremely numerous. Among them, organic compounds - carbohydrates, proteins and nucleic acids, which are composed of carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus, are the most important organic compounds in cells.
- Q: What is the aromatic hydrocarbon .. what is the derivative of the aromatic hydrocarbon
- Aromatic hydrocarbons referred to as "aromatic hydrocarbons", refers to the molecule containing benzene ring structure of the hydrocarbons. Is a closed chain.
