Q: Is carbon monoxide an organic gas?: The organic compound contains carbon, hydrogen, oxygen, nitrogen and other elements, a few also contain sulfur, phosphorus, halogen, etc. Any kind of organic compounds, its molecular composition contains carbon, the vast majority also contains hydrogen Elements. Since the hydrogen atoms of the organic compound molecules can be replaced by other atoms or radicals, resulting in a lot of other organic compounds, so modern people generally believe that hydrocarbons and their derivatives known as organic compounds, referred to as organic matter.

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: What is the relationship between hydrocarbon and hydrocarbon derivatives?: 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: 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: Will AsH3 (arsenic trioxide) is organic or inorganic: AsH3 (arsine trihydride) is not containing C element

Q: The aromatic hydrocarbon derivative refers to monocyclic or polycyclic: To see what is the derivative of aromatic hydrocarbons, by its own is a single ring or multi-ring decision

Q: What is the difference between hot and cold asphalt?: Grandmother next door aunt is the street to sell stewed meat, a child often see her burning a pot of hot asphalt pork hair, black asphalt boiled immediately leaching in the meat, and so dry quickly pull it down, pork will Change very clean and white, clean the meat will be directly thrown into the pot halogen system, this method relative to the traditional plucking save time and effort a lot. Here, please bloggers blame me to come to funny, because the end of the story is not funny, that aunt's little sister in the sixth grade when suffering from leukemia away, adults say with her home burning asphalt There are relationships, eighteen years later, and she only a few side of the edge of the I actually remember the full name of her sister, her looks, the tone of her voice, we played the game and we were a very curious In the asphalt pot to see the scene of pig hair ... ... hope that each parents do not ignore the child's growth in the small problem.

Q: What cells are composed of compounds: The organic matter that constitutes the cell generally refers to the general term for carbon-containing compounds or hydrocarbons and their derivatives. In nature, the types of organic matter are extremely numerous. Among them, organic compounds - carbohydrates, proteins and nucleic acids, which are composed of carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus, are the most important organic compounds in cells.

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.

Q: Junior high school chemistry knowledge, please explain what is organic compounds, inorganic compounds.: 2. Previously, the known organic matter is obtained from animals and plants and other organisms, so this kind of compound is called organic matter. To the 1820s, scientists have used inorganic synthesis of many organic compounds, such as urea, acetic acid, fat, etc., to break the organic matter can only be obtained from the organic concept. However, due to historical and customary reasons, people still use the name of organic matter.
