Q: What is organic matter?: Organic compounds (organic compounds) mainly by the oxygen elements, hydrogen, carbon elements. Organic matter is the material basis for life. Fat, amino acids, protein, sugar, heme, chlorophyll, enzymes, hormones and so on. Biological metabolism and biological genetic phenomena, are related to the transformation of organic compounds. In addition, many substances closely related to human life, such as oil, natural gas, cotton, dyes, chemical fiber, natural and synthetic drugs, are organic compounds.

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).: Organic matter carries more richer and more easily utilized by creatures

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: Is polyethylene a derivative of hydrocarbons?: The definition is yes

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?: Now, the improved economic benefits of FT still limit its further development. Some of the enterprises' coal indirect liquefaction projects have been terminated (for example, Shenhua Group), coupled with the impact of breakthrough development of shale oil technology, the development prospect of coal indirect liquefaction not optimistic.

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: 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.

Q: Is the number of hydrogen atoms in the hydrocarbon or hydrocarbon derivative molecule be even: The number of hydrogen atoms in the hydrocarbons containing carbon, oxygen and oxygen is also even.

Q: NH4HCO3 and so have C atoms ah, why still inorganic: Not all carbon compounds are organic compounds, CO, CO2, carbonic acid, carbonates (including salt and acid salts), metal carbides, cyanides, thiocyanates are inorganic compounds.

Q: Why can organic matter be unique in chemical substances? What is the nature of the C atom?: Organic this historical term, can be choked to the 19th century, when the students that organic compounds can only be biological (life-force, vis vitalis) synthesis. This theory is based on organic matter and "inorganic" the basic difference, organic matter can not be non-vitality synthesis. But later this theory was overthrown, the German chemist Friedrich W?hler to cyanide and ammonia synthesis of urea (inorganic synthesis of organic matter). In general, organic compounds are defined as compounds with hydrogen bonds and inorganic compounds are not. Therefore, carbonic acid (H2CO3), carbon dioxide is an inorganic compound, but formic acid (also known as formic acid) (HCOOH, the first fatty acid) is an organic compound.
