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: 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: Is not organic matter must not hydrogen ah?: Not without hydrogen, there must be C, but the material containing C is incomplete organic matter. Like H2CO3 and carbonate

Q: Is acrylamide an oxygen-containing derivative of hydrocarbons?: There are many kinds of oxygen-containing derivatives of alcohols which can be classified into alcohols, phenols, aldehydes, carboxylic acids and esters, etc. The nature of the oxygen-containing derivatives of hydrocarbons is determined by the functional groups, and the nature of the organic compounds can be used to synthesize the oxygen- There is no organic matter to meet our needs.

Q: What is the meaning of organic ah, organic food on the human body what practical benefits: Food point of view of organic: from planting to harvest, and then to storage, transport so that consumers in the hands, without chemical fertilizers, chemical processing, genetic technology and other food raw materials. In general, organic represents high quality and natural. But the Chinese market is not very close, so the choice of time to pay attention.

Q: Are hydrocarbons all organic?: A series of organic compounds, also known as "hydrocarbons." Many types, according to the structure and nature,

Q: From the molecular level, are not all the energy obtained from the redox reaction?: Because one to be recycled, and secondly to be converted into electricity

Q: Other corals are because the color of the corals show colorful, why only the red coral is the exception of it? did not find the reasons for the big god to explain: Calcium coral is the main component of calcium carbonate, in addition to about 3% of magnesium carbonate and 1.5% to 4% of organic matter, and trace amounts of silicon and iron. The presence of organic matter increases the toughness of corals, making it better for processing and polishing. Calcium coral colors are mostly white or gray, but when it contains a considerable amount of different impurities, it is possible to show red, pink, orange, yellow, blue, purple and other colors. Therefore, by the living environment and many other factors, the same kind of coral can have different colors, and different types of corals and stars showing the same color. Red coral is really because of carotene.
