Q:What is organic matter? Candle is organic?
Organic matter refers to the addition: carbon, carbon monoxide, carbon dioxide, carbonated and carbonate carbon compounds
Q:Is the heterocyclic compound not a derivative of cyclic hydrocarbons? why?
Aromatic hydrocarbons referred to as "aromatic", usually refers to the molecules containing benzene ring structure of hydrocarbons. Is a kind of closed-chain class.
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: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 it possible to understand that organic matter is contained in the heat of inorganic matter?
The fundamental difference between organic matter and inorganic matter is whether it contains carbon elements (except carbon monoxide, carbon dioxide, carbonates, metal carbides and other simple carbon compounds). Is the carbon-based life (that is, we) the division of life material and non-life material academic concept. Regardless of whether or not to store heat. The ability of many inorganic materials to store heat is much higher than that of organic matter. From a broad cosmic perspective. Organic and inorganic division does not make sense, assuming that there is a silicon-based life (this possibility is very high). Then their organic and inorganic division should lie in whether it contains silicon.
Q:Why not ah?
A series of compounds in which a hydrogen atom in a hydrocarbon molecule is replaced by another atom or radical is called a derivative of a hydrocarbon
Q:Why is the chemical name in the uncommon word so much?
The title as a Chinese people are not proud of it Do not let you change the way back? Japanese back a element you a cycle almost finished finished ok Chinese can also sideways back to the back of foreign chemistry can cycle table How much is the back? Chinese people want to back half a day to solve the ok
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 can hydrocarbons crack to carbon and hydrogen at high temperatures?
It is almost impossible for this problem to look at your reaction conditions. Generally speaking, the alkane reaction is mainly difficult to decompose directly into ions
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.
