- Q:What is the definition of organic matter
- Organic matter usually refers to carbon-containing compounds, or hydrocarbons and their derivatives are collectively referred to as organic compounds.
- Q:Is polyethylene a derivative of hydrocarbons?
- No, the derivative of the hydrocarbon is an element other than c.H
- Q:Are hydrocarbons are hydrocarbons and that alcohols? Is it carbon dioxide?
- Should be a hydroxy compound.
- 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: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.
- Q:Is the number of hydrogen atoms in the hydrocarbon or hydrocarbon derivative molecule be even
- The number of hydrogen atoms in the hydrocarbons containing carbon, oxygen and oxygen is also even.
- Q:What is the difference between an aromatic compound and a hydrocarbon derivative?
- The aromatic compound is a benzene ring containing compound, which may be a hydrocarbon or a hydrocarbon derivative. Hydrocarbons are hydrocarbon-containing compounds, and hydrocarbons containing hydrocarbons other than hydrocarbons are derivatives of hydrocarbons. The two concepts have crossed.
- Q:What is the proportion of hydrocarbons synthesized by Fischer-Tropsch Synthese in liquid fuels consumed by Nazi Germany? What are the proportions of these hydrocarbons as an industrial raw material into their military industry, in addition to fuel? At that time, did the Fischer-Tropsch preparations occupy an important position in Nazi Germany's military industry or heavy industry?
- The traditional FT synthesis method of the product of heavy hydrocarbon content is high, the composition is complex, so the combustion efficiency is not optimistic. Germany is in view of the supply of oil is less than consumption (loss of production areas and lack of refined production capacity) was forced to take the FT technology to add (Germany's local coal reserves larger). So the FT fuel in the World War II Germany's energy system accounted for little, the specific data is still controversial, there are 15% and 25% said.
- Q:What is the meaning of organic ah, organic food on the human body what practical benefits
- Chemical point of view, organic is organic matter, mainly by the carbon atoms and hydrocarbons derivatives.
- Q:Hydrocarbons and hydrocarbon derivatives are not all non-electrolytes
- Hydrocarbons are, derivatives are not necessarily, such as organic acids (formic acid, acetic acid, etc.)
