Q:Why is dry ice not organic?: Organic compounds are mainly composed of oxygen, hydrogen, and carbon, and organic matter is the material basis for life.

Q:Identification of Derivatives of Chemical Hydrocarbons in High School: Derivatives have gone, and give a specific range Well

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:What cells are composed of compounds: Protein and water

Q:Is the number of hydrogen atoms in the hydrocarbon or hydrocarbon derivative molecule be even: The number of hydrogen atoms in the hydrocarbon must be even.

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 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:What is organic?: Organic products are from the organic agricultural production system, according to the international organic agricultural production requirements and the corresponding standard production and processing, and through third-party geographical and organic certification bodies certified all agricultural and sideline products, including food, vegetables, fruits, dairy products, animal products , Honey, aquatic products, spices, cosmetics, and even textiles, forest products, biological pesticides, organic fertilizers and so on. Is the organic cultivation of pesticides, fertilizers, contaminated raw soils, grows in the closest way to nature, and never uses synthetic compounds, fertilizers and transgenic technologies during the growth process. In the process of production In the absence of any synthetic chemical composition. From the processing, production, packaging the whole process is in line with environmental protection and health principles. International standards of organic certification required by the third-year certification bodies from the cultivation, processing, production, manufacturing, to the finished product wholesale process for review.

Q:Junior high school chemistry knowledge, please explain what is organic compounds, inorganic compounds.: 4. A wide variety of organic matter, hydrocarbons and hydrocarbons can be divided into two major categories of derivatives. According to the organic groups contained in the functional groups, divided into alkanes, alkenes, alkynes, aromatic hydrocarbons and alcohols, aldehydes, carboxylic acids, esters and so on. According to the organic carbon molecular structure, can also be divided into open chain compounds, carbocyclic compounds and heterocyclic compounds three categories.

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.
