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: 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: Is the oxygen derivative of the hydrocarbon a non-methane total hydrocarbon?: Hydrocarbon derivatives of hydrocarbons do not belong to non-methane total hydrocarbons

Q: Inorganic chemistry employment direction? Current research direction: Optical inorganic boring, and now are with rare earth elements and radioactive elements to do some material research. Or electrochemical. battery!

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: The main components of the red coral bone or coral as the general calcium carbonate. But the red coral bones can be made into jewelry, mainly due to its large bone density, the crystalline form of calcium carbonate for the triangular calcite rather than other common hard coral orthorhombic aragonite. Different crystal forms, combined with the trace element composition ratio is mainly Mg / Ca ratio and Ba / Ca ratio, even the same kind of red coral color texture is also slightly changed. This difference is the red coral growth environment and seawater composition may be, therefore, red coral skeletal trace element ratio has become the growth environment, the most important proof of the collection.

Q: What is organic?: Simply refers to the organic ingredients containing organic ingredients. The real organic cosmetics are organic plants as the main raw material, do not add artificial spices, artificial colors, oil-free ingredients, the added preservatives and surfactants must be strictly limited, and the manufacturing process to comply with the relevant provisions, can not use animals Experiments and the use of radiation sterilization products. In general, the certification of organic skin care products must meet the following conditions: First, the organic environment, the closest growth of natural growth, production base (ie, the environment) are not damaged, water (irrigation water), soil (soil ), Gas (air) is not contaminated. Second, organic cultivation, no artificial fertilizer irrigation or artificial feed, without antibiotics, chemical insecticide, without genetic variants. Third, the organic processing and production projects, including the harvest after washing, finishing, packaging, processing, transportation, storage, sales and other sectors) did not subject to secondary pollution.

Q: Organic chemistry, naming of derivatives containing oxygen (hetero) atomic bridged cyclic hydrocarbons: A little bit of a way to draw out with chemdraw, then convert structure to name

Q: Why can organic matter be unique in chemical substances? What is the nature of the C atom?: To give a reason, the current production of more economical temperature control is limited.

Q: Carbon compounds (except inorganic carbon compounds), hydrocarbons and derivatives of the general term is?: Hydrocarbons and hydrocarbon derivatives
