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, halogenated hydrocarbons, esters are difficult to dissolve in water. Hydrocarbons, esters are denser than water, and the density of halogenated hydrocarbons is generally greater than that of water. Hydrocarbon derivatives containing hydroxyl, amino or aldehyde groups such as alcohols, phenols, aldehydes, carboxylic acids, sulfonic acids and amines are soluble in water, And the shorter the solubility of the carbon chain, the greater the solubility of the carbon chain increases, until the same number of carbon atoms and similar hydrocarbons.

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: 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: Are there two derivatives of equivalent hydrogen?: You give the scope is too broad, at least to set in what kind of functional group range ah.

Q: Hydrocarbons and hydrocarbon derivatives are not all non-electrolytes: Hydrocarbons are, derivatives are not necessarily, such as organic acids (formic acid, acetic acid, etc.)

Q: Artemisinin is not a derivative of hydrocarbons: There are many types of hydrocarbons, flammable and explosive materials, the structure of the known hydrocarbons in more than 2000. The hydrocarbon is the parent of the organic compound, and the other various organic compounds can be regarded as derivatives of one or more hydrogen atoms in the hydrocarbon molecule being replaced by atoms or radicals of other elements.

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?: I only heard the warm mix of asphalt. The How is cold asphalt defined? How much is it cool?

Q: What is the current status of carbon dioxide capture technology and how is it compared to plants that absorb carbon dioxide?: Landlord can check their own literature what. = For example, I think this review is very good. The Although it does not include relatively new progress, but I think it is quite good. The You see such an answer to the efficiency of how low ah not as good as their own to find the literature to see right
