Q: What is carbohydrate? What is organic? What is it?: Compounds associated with the body (a few of the body-related compounds are inorganic compounds, such as water), usually carbon-containing compounds, but some simple carbon compounds such as carbon monoxide, carbon dioxide, carbonates, metal carbides, cyanides And so on. In addition to carbon containing elements, the vast majority of organic compounds containing hydrogen molecules in the molecule, and some also oxygen, nitrogen, halogen, sulfur and phosphorus and other elements. There are nearly 6 million organic compounds known. In the early days, organic compounds were substances that were obtained from animals and plants. Since 1828, the boundary between organic matter and inorganic matter disappears after artificial synthesis of urea [(NH2) 2CO], the term "organic" is still used for historical and customary reasons. Organic compounds are of great importance to humans, and all forms of life on earth, mainly composed of organic matter. For example: 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: Ionic compounds, covalent compounds, electrolytes, non-electrolytes, which are both compounds and inorganic compounds: An ionic compound consisting of a cation and an anion. Active metals (such as sodium, potassium, calcium, magnesium, etc.) and active non-metallic (such as fluorine, chlorine, oxygen, sulfur, etc.) when the combination of active metal loss of electrons to form positively charged cations (such as Na +, K +, Ca2 + (Such as F-, Cl-, O2-, S2-, etc.), cations and anions are formed by electrostatic interactions to form ionic compounds. For example, sodium chloride is an ionic compound consisting of positively charged sodium ions (Na +) and negatively charged chloride ions (Cl-). Many bases (such as NaOH, KOH, Ba (OH) 2, etc.) and salts (such as CaCl2, KNO3, CuSO4, etc.) are ionic compounds. The total number of positive charges in the cationic compound is equal to the total number of negative charges carried by the anion, and the whole compound is electrically neutral. Most ionic compounds can not be conductive in solid (or crystalline), while their aqueous or molten state can be conductive. The ionic compounds generally have a higher melting point and higher boiling point, higher hardness, crisp and difficult to compress, and the highly volatile ionic compounds are linked by ionic bonds, without independent structures, such as sodium chloride.

Q: What is the hydrocarbon thing: Hydrocarbons can be divided into: open chain hydrocarbons (carbon atoms in hydrocarbon molecules in open chain) - saturated hydrocarbons - alkanes - unsaturated hydrocarbons - olefins and polyolefins (carbon - carbon double bonds, unstable) - alkynes and (Cyclopentane) - cycloalkene - cycloalkyne aromatic hydrocarbon - monocyclic aromatic hydrocarbon (benzene and its homologues) - fused ring aromatic hydrocarbons (Polycyclic aromatic hydrocarbons and their homologues) - polycyclic aromatic hydrocarbons (naphthalene, anthracene and other condensed ring aromatic hydrocarbons and their homologues) all hydrocarbons are hydrophobic, that all the hydrocarbons are not soluble in water and coal The main ingredients are hydrocarbons

Q: Why does the molecular atom compound do not belong to the life structure: Life structure is composed of CHO as the main element through the covalent bond of the combination of hydrocarbons and their derivatives, and you said the molecular atomic compounds are usually atomic or ionic bond

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: The functional group of the derivative of the hydrocarbon: Yes, the number of carbon after a certain, only to determine the nature of the functional group. This is also the reason for the name of the functional group

Q: What is the difference between hot and cold asphalt?: Cold mixed high-strength asphalt concrete, by adding asphalt in the thermosetting resin, coupled with the right amount of solvent to form a semi-flow asphalt binder, and the appropriate mix of aggregate from the asphalt concrete mixture. This asphalt concrete is a very high strength of 60 ℃, 30mm Marshall stability of 30000N, flow 20-30 (1 / 10mm), the stability of ordinary asphalt concrete is about 3 times, with good rutting resistance. Hot asphalt is composed of different molecular weight hydrocarbons and non-metallic derivatives of dark brown complex mixture, is a high viscosity organic liquid, was liquid, the surface was black, soluble in carbon disulfide. Asphalt is a waterproof moisture and corrosion of organic cementitious materials. Asphalt can be divided into coal tar pitch, petroleum asphalt and natural asphalt three: Among them, coal tar pitch is a by-product of coking. Petroleum asphalt is the residue after distillation of crude oil. Natural asphalt is stored in the ground, and some of the formation of ore or in the crustal surface accumulation. Asphalt is mainly used for coatings, plastics, rubber and other industries and pavement and so on.

Q: Organic chemistry studies the performance of hydrocarbons and their derivatives, either right or wrong: Organic compounds refer to hydrocarbons and their derivatives. Organic chemistry is the study of the structural characteristics of organic compounds, synthetic methods and physical and chemical properties of the chemical.

Q: What is the aromatic hydrocarbon .. what is the derivative of the aromatic hydrocarbon: Aromatic hydrocarbons referred to as "aromatic hydrocarbons", refers to the molecule containing benzene ring structure of the hydrocarbons. Is a closed chain.
