Q: What are the gaseous states of the oxygen-containing derivatives of the hydrocarbons under the standard conditions?: Hydrocarbon derivatives of oxygen in the standard conditions are gaseous formaldehyde.

Q: What is a derivative of a hydrocarbon? What is an aromatic hydrocarbon derivative?: Hydrocarbon derivatives include derivatives of linear and aromatic hydrocarbons such as chloroethane bromopropane bromobenzene

Q: Why is dry ice not organic?: Organic compounds are mainly composed of oxygen, hydrogen, and carbon, and organic matter is the material basis for life.

Q: Will AsH3 (arsenic trioxide) is organic or inorganic: So the organic matter must contain the element is the C element

Q: Is not organic matter must not hydrogen ah?: Not without hydrogen, there must be C, but the material containing C is incomplete organic matter. Like H2CO3 and carbonate

Q: Artemisinin is not a derivative of hydrocarbons: A hydrocarbon is an organic compound (called a hydrocarbon) composed of two elements, carbon and hydrogen, and a hydrocarbon. Can be simply divided into open chain hydrocarbons, alicyclic hydrocarbons and aromatic hydrocarbons, all hydrocarbons are hydrophobic, that all the hydrocarbons are not soluble in water.

Q: Is steel not organic synthetic material?: Organic compounds that are organic compounds. Carbon compounds (carbon monoxide, carbon dioxide, carbonic acid, carbonates, metal carbides, cyanide excluded) or hydrocarbons and their derivatives in general. Most of the combustion can produce carbon dioxide and water.

Q: What is the current status of carbon dioxide capture technology and how is it compared to plants that absorb carbon dioxide?: The principle is probably that the middle of the thing is the electrode, and then the surface of the electrode there are some powerful catalyst in the sunlight can promote the oxidation of water or carbon dioxide reduction. The electrode can move the proton to the other side and not allow the product or product to move to the other side. After the proton has been transferred, the electrochemical process can be used to hydrogenate the carbon dioxide.

Q: Is grease a polymer compound? Is it a derivative of saturated hydrocarbons?: Grease is not a polymer, a hydrocarbon (not necessarily a saturated hydrocarbon) derivative,

Q: Why artemisinin and its derivatives in the molecular structure of a peroxide chain, the chemical properties are more stable?: Artemisinin is relatively stable, is relative to other organic peroxide in terms of, in general, most of the organic peroxide instability, heating easily decomposed, and some even easy to burn the explosion, such as dibenzoyl peroxide, but crystal cyan Artemisinin heating to the melting point does not break down, has been considered stable.
