Q: Why the silicon hydride less, a lot of hydrocarbons. (Why did not you find silicon-based creatures) and why are so many oxides of silicon, little carbon oxides?: Silicon oxide than carbon, because the outermost layer of silicon has three levels ah, (SiO, SiO2, Si2O6) silicon less organic matter, the front also said that the organic instability of silicon

Q: Compare the difference between London smoke and Los Angeles photochemical smog: Los Angeles photochemical smog nitrogen content and hydrocarbons and derivatives more, mainly close to the car exhaust. Foggy London situation related to coal, soot solid particles and sulfur oxide more. Foggy London is more bleak, and Los Angeles is more toxic.

Q: Why does toluene not belong to the derivatives of hydrocarbons?: Hydrocarbon: sound tīng, is composed of two elements of carbon and hydrogen organic compounds known as hydrocarbons, also known as hydrocarbons. It reacts with chlorine, bromine, oxygen and other hydrocarbons to produce derivatives of hydrocarbons. Such as methane and chlorine in the light conditions of reaction to produce methyl chloride, dichloromethane, chloroform and chloroform (carbon tetrachloride) and other derivatives. The concept of derivatives is hydrocarbon and chlorine, bromine, oxygen and other reaction products. While toluene is not methyl and benzene, she is a whole noun is aromatic. Also known as aromatic hydrocarbons. Generally have one or more six-ring (benzene ring) with a special structure. The simplest aromatic hydrocarbons are benzene, toluene, xylene. There is also naphthenes. As the name suggests it is a ring structure. The most common is the five carbon atoms or six carbon atoms of the ring, the former called cyclopentane, which is called cyclohexane. The molecular formula of the cycloalkane is of the formula CnH2n. Cycloalkane is also called cycloalkane hydrocarbons. And alkanes. Is a carbon atom between the single bond phase chain hydrocarbon. Since the number of atoms that make up the hydrocarbon and hydrogen is different, the result is that the petroleum contains hydrocarbon molecules with large and small differences. Alkanes are named according to the carbon atoms and numbers contained in the molecule, and the number of carbon atoms is less than 10, from 1 to 10, followed by a, B, C, D, E, G, Alkane to say that the number of carbon atoms in more than 11, with the number that thank you to adopt

Q: Organic organic compounds are organic matter?: Organic polymer compounds are organic matter

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: Are the asphalt and peat kinds of vegetables have heavy metal?: Asphalt and its flue gas on the skin and mucous membranes are irritating, phototoxic and carcinogenic effects. China's three major asphalt toxicity: coal tar pitch> shale asphalt> petroleum asphalt, the former two are carcinogenic. Asphalt main skin lesions are: phototoxic dermatitis, skin lesions limited to the face, neck and other exposed parts; black disease, skin lesions are often symmetrical distribution in the exposed parts, was flaky, brown - dark brown - brown black; Acne; verrucous vegetation and heat burns caused by accidents. In addition, there are dizziness, head swelling, headache, chest tightness, fatigue, nausea, loss of appetite and other systemic symptoms and eye, nose, throat irritation symptoms.

Q: China's largest asphalt production base where: Asphalt material is divided into asphalt and tar asphalt two categories. Asphalt is divided into natural asphalt and petroleum asphalt, natural asphalt is the oil exudation surface after long-term exposure and evaporation of the residue; oil asphalt is refined processing of residual oil residue, the appropriate process to deal with the product The Tar asphalt is coal, wood and other organic dry distillation processing of the tar after re-processing products. Most of the asphalt used in the project is petroleum asphalt, and petroleum asphalt is a mixture of complex hydrocarbons and their nonmetallic derivatives. Usually the asphalt flash point between 240 ℃ ~ 330 ℃, the ignition point than the flash point of about 3 ℃ ~ 6 ℃, so the construction temperature should be controlled below the flash point.

Q: Peracetic acid is not: A series of compounds produced by the substitution of hydrogen atoms in other molecular or atomic groups as hydrocarbon derivatives, peroxyacetic acid is CH3COOOH, and should be considered

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 are the characteristics of organic compounds?: Organic compounds are usually referred to as carbon-containing compounds, or hydrocarbon-containing compounds and their derivatives are collectively referred to as organic matter. Organic compounds are generally insoluble in water and soluble in organic solvents with lower melting points. The vast majority of organic matter heat easily decomposed, easy to burn. The reaction of organic matter is generally slow and often accompanied by side effects, and there are many kinds of organic compounds, which can be divided into two major categories of hydrocarbon and hydrocarbon 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.
