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: What are the gaseous states of the oxygen-containing derivatives of the hydrocarbons under the standard conditions?: Nitrogen derivatives are; dimethylamine;

Q: Ionic compounds, covalent compounds, electrolytes, non-electrolytes, which are both compounds and inorganic compounds: An electrolyte is a compound capable of being conductive in an aqueous solution or in a molten state, such as an acid, a base and a salt. Those compounds that can not be electrically conductive in the above cases are non-electrolytes such as sucrose, alcohol and the like.

Q: Chemical life network: chemical (inorganic reaction, organic reaction) is equal to the life of life reaction?: Research on the origin, preparation, structure, nature, change and application of elements, elements and inorganic compounds.For the comprehensive utilization of mineral resources, the production and research of inorganic raw materials and functional materials in modern technology are of great significance At present, inorganic chemistry is in the new period of vigorous development, and many edge areas are rapidly rising and the scope of research has been expanded. Inorganic synthesis, high - element chemistry, coordination chemistry, organometallic chemistry, inorganic solid chemistry, bio - inorganic chemistry and isotope Chemical and other fields.

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

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: Will AsH3 (arsenic trioxide) is organic or inorganic: Organic matter refers to carbon-containing compounds, or hydrocarbons and their derivatives are collectively referred to as organic compounds.

Q: Sodium can be used to identify derivatives of hydrocarbons: Sodium can identify hydrocarbon derivatives that are alcohol

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: Calcium coral is the main component of calcium carbonate, in addition to about 3% of magnesium carbonate and 1.5% to 4% of organic matter, and trace amounts of silicon and iron. The presence of organic matter increases the toughness of corals, making it better for processing and polishing. Calcium coral colors are mostly white or gray, but when it contains a considerable amount of different impurities, it is possible to show red, pink, orange, yellow, blue, purple and other colors. Therefore, by the living environment and many other factors, the same kind of coral can have different colors, and different types of corals and stars showing the same color. Red coral is really because of carotene.

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.
