Q: What is carbohydrate? What is organic? What is it?: Carbohydrates, also known as carbohydrates, are the most abundant and most widely distributed organic compounds in nature. Mainly by the carbon, hydrogen, oxygen composition. Glucose, sucrose, starch and cellulose all belong to carbohydrates.

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: What is the relationship between hydrocarbon and hydrocarbon derivatives?: Hydrocarbons, which are composed of two elements, carbon and hydrogen, are called hydrocarbons and hydrocarbons. It reacts with chlorine, bromine vapor, oxygen, etc. to produce hydrocarbons.

Q: China's largest asphalt production base where: Oil asphalt is the residue after distillation of crude oil. According to the degree of extraction of different, at room temperature into a liquid, semi-solid or solid. Oil asphalt color black and shiny, with a high temperature. Because it is in the production process has been distilled to 400 ℃ or more, and thus contain little volatile components, but there may still be high-molecular hydrocarbons without volatile, these substances are more or less harmful to human health.

Q: The functional group of the derivative of the hydrocarbon: Yes, the number of carbon after a certain, only to determine the nature of the functional group. This is also the reason for the name of the functional group

Q: Cracked: It is almost impossible for this problem to look at your reaction conditions. Generally speaking, the alkane reaction is mainly difficult to decompose directly into ions

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: What is the difference between hot and cold asphalt?: According to the time analysis, municipal companies should use the cold asphalt cold material, is the winter road maintenance of commonly used materials. In the long winter, the asphalt pavement works because of the temperature (less than 5 degrees is strictly prohibited construction), is very little construction, even if the construction, the quality is higher than the temperature when the construction is worse (asphalt mixture cold fast, easily lead to compaction The lack of pressure on the pressure, and prone to cohesive, poor water quality problems such as water), because no demand or demand is small, this time the major asphalt mixing field have a holiday home to the New Year. But the road will be the same as the winter disease, pit and other small diseases are not treated in time, easy to evolve into a large disease, there may be dangerous roadbed, running up the driver also curse, out of the accident maintenance department also bear responsibility, so the winter road Also need to maintain. At this time asphalt cold feed came into being, asphalt cold feed is used aggregate (graded gravel) plus dehydration asphalt plus diesel and additives mixed with the construction of the temperature requirements, the pits filled with pavement , Such as diesel fuel has finished bitter gluing together, but the construction quality is not good, no hot mix asphalt dense. So the winter is approaching, the road maintenance department will need to mix a few tons of asphalt cold feed sealed (to participate in 25kg rice), there are pits to pull a few bags to fill, and so on these problems when the pit and digging with the heat Mixed with asphalt material repair. In summary, the asphalt cold feed is a special winter pavement pit repair using the material, the construction process and hot mix asphalt material is roughly the same, but the construction quality is relatively poor, is a special time emergency measures, very useful materials.
