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: 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: 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: What is "organic" and "inorganic" in chemistry?: Inorganic compounds are inorganic compounds, usually refers to non-carbon compounds. , Alkali, salt and so on.

Q: Is acrylamide an oxygen-containing derivative of hydrocarbons?: High school stage seems to learn alcohol, phenol, aldehyde, carboxylic acid and esters and amino acids

Q: What is the meaning of organic ah, organic food on the human body what practical benefits: Food point of view of organic: from planting to harvest, and then to storage, transport so that consumers in the hands, without chemical fertilizers, chemical processing, genetic technology and other food raw materials. In general, organic represents high quality and natural. But the Chinese market is not very close, so the choice of time to pay attention.

Q: From the molecular level, are not all the energy obtained from the redox reaction?: Because one to be recycled, and secondly to be converted into electricity

Q: What is organic?: Organic products are from the organic agricultural production system, according to the international organic agricultural production requirements and the corresponding standard production and processing, and through third-party geographical and organic certification bodies certified all agricultural and sideline products, including food, vegetables, fruits, dairy products, animal products , Honey, aquatic products, spices, cosmetics, and even textiles, forest products, biological pesticides, organic fertilizers and so on. Is the organic cultivation of pesticides, fertilizers, contaminated raw soils, grows in the closest way to nature, and never uses synthetic compounds, fertilizers and transgenic technologies during the growth process. In the process of production In the absence of any synthetic chemical composition. From the processing, production, packaging the whole process is in line with environmental protection and health principles. International standards of organic certification required by the third-year certification bodies from the cultivation, processing, production, manufacturing, to the finished product wholesale process for review.

Q: Why can organic matter be unique in chemical substances? What is the nature of the C atom?: Organic this historical term, can be choked to the 19th century, when the students that organic compounds can only be biological (life-force, vis vitalis) synthesis. This theory is based on organic matter and "inorganic" the basic difference, organic matter can not be non-vitality synthesis. But later this theory was overthrown, the German chemist Friedrich W?hler to cyanide and ammonia synthesis of urea (inorganic synthesis of organic matter). In general, organic compounds are defined as compounds with hydrogen bonds and inorganic compounds are not. Therefore, carbonic acid (H2CO3), carbon dioxide is an inorganic compound, but formic acid (also known as formic acid) (HCOOH, the first fatty acid) is an organic compound.

Q: How the most primitive life on earth is produced under what conditions: In the 4 billion years ago, the Earth's water environment, the atomic group into molecules, the formation of a new four-balance body, and the Earth in the formation process, has gathered a lot of interstellar organic molecules, these molecules combined into macromolecules, Of the gravitational field and the anti-gravitational field to find the appropriate combination of objects. Macromolecules, molecules and atoms are also dependent on the formation of the force field to find the appropriate combination of objects, the formation of a new complex four-force balance body, where the gravitational field to play a long-range attraction (5-20 atomic diameter), which It also limits the macromolecules to obtain the desired combination of objects on a large scale, so macromolecules are combined into a moving tissue form, the most primitive marine microorganism. The macromolecules that move can mainly use the method of orienting the electromagnetic force to gradually develop into the original tissue that can swim in the water, so they can obtain a large amount of food (four-force balance) and accumulate some molecules in the body , These molecules in the original microbial parent force field guidance, combined with the mother similar to the new micro-organisms, these primitive microorganisms is essentially a complex macromolecule formation of the four balance body, which is the prototype of biological gene replication.
