Q: What is the isomeric structure of oxygen-containing derivatives?: Play the Transformers. As long as the same molecular formula, you can group out how many different structures, there are a number of isomers.

Q: What does organic and inorganic mean?: [Inorganic] inorganic is inorganic compounds referred to, usually refers to non-carbon compounds. A small number of carbon-containing compounds, such as carbon monoxide, carbon dioxide, carbonates, cyanides, etc. are also inorganic. Inorganic materials can be divided into oxides, acids, alkalis, salts and so on. Organic compounds Definitions Organic compounds usually refer to carbon-containing compounds, or hydrocarbons, and their derivatives, are collectively referred to as organic compounds.

Q: High school chemical hydrocarbons with hydrocarbon derivatives with water solubility, density for accurate and comprehensive summary, thank you. Out of college entrance examination: Hydrocarbons are insoluble in water and have a lower density than water

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: Will AsH3 (arsenic trioxide) is organic or inorganic: Organic matter refers to carbon-containing compounds, or hydrocarbons and their derivatives are collectively referred to as organic compounds.

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: What is the most primitive person on earth?: These macromolecules are not in the modern sense of the protein and nucleic acid polymer, but a variety of amino acids, nucleosides, phosphoric acid, carbohydrates and some other small molecules of the disorder of the polymer, when the nucleoside and phosphoric acid composition of nucleoside Acid, and gradually form a nucleotide chain, the formation of these nucleotide chain of the amino acid on the formation of the field of binding force, and then assembled peptide chain. Or by the combination of a variety of amino acids into peptide chain formed by the force field on the surrounding nucleus formation field binding effect, and then assembled the nucleotide chain, with the formation of peptide chain and nucleotide chain longer and longer , The molecular weight is growing, and ultimately the formation of nucleic acids and proteins, nucleic acid and protein formation is the product of interaction with each other, is generated at the same time.

Q: What is the difference between hot and cold asphalt?: Grandmother next door aunt is the street to sell stewed meat, a child often see her burning a pot of hot asphalt pork hair, black asphalt boiled immediately leaching in the meat, and so dry quickly pull it down, pork will Change very clean and white, clean the meat will be directly thrown into the pot halogen system, this method relative to the traditional plucking save time and effort a lot. Here, please bloggers blame me to come to funny, because the end of the story is not funny, that aunt's little sister in the sixth grade when suffering from leukemia away, adults say with her home burning asphalt There are relationships, eighteen years later, and she only a few side of the edge of the I actually remember the full name of her sister, her looks, the tone of her voice, we played the game and we were a very curious In the asphalt pot to see the scene of pig hair ... ... hope that each parents do not ignore the child's growth in the small problem.

Q: NH4HCO3 and so have C atoms ah, why still inorganic: Organic matter is a general term for carbon compounds (except carbon oxides, carbon dioxide, carbonates, carbonates, bicarbonates, metal carbides, cyanides, thiocyanides and other oxides) or hydrocarbons and their derivatives. Organic matter is the material basis for life. The inorganic compound usually refers to a compound containing no carbon element, but a few carbon-containing compounds such as carbon dioxide, carbonic acid, carbon monoxide, carbonate and the like do not have the properties of an organic substance, and therefore such substances are also inorganic.
