Q:What are the nature of sugar
Carbohydrates, also known as carbohydrates, are the most abundant and most widely distributed organic compounds in nature. Mainly by the carbon, hydrogen, oxygen composition. Glucose, sucrose, starch and cellulose all belong to carbohydrates.
Q:How to distinguish between inorganic chemicals and organic chemicals
If the chemical can be dissolved in water, then it is likely that inorganic chemicals, because organic chemicals only a few substances such as ethanol and acetic acid can be dissolved in water. In addition, inorganic chemicals are mostly solid or aqueous solution, and organic chemicals are mostly liquid and odor.
Q:Are hydrocarbons all organic?
A series of compounds with similar structures and different molecular composition of one or several "CH2" radicals are called the same series, and each member in the same series is called homologous, and the chemical properties of homologues are similar due to their similar structure. Their physical properties, often with the increase in molecular weight and regular changes.
Q:What is the position of Fischer-Tropsch synthetic hydrocarbons in Nazi Germany's military 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:Is the oxygen derivative of the hydrocarbon a non-methane total hydrocarbon?
Since it is a hydrocarbon, it is bound to be a hydrocarbon, and the oxygen derivative of the hydrocarbon is not a hydrocarbon! Therefore, even if the oxygen-containing derivative is volatile again, it is not a non-methane total hydrocarbon
Q:What is organic 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.
Q:Are the asphalt and peat kinds of vegetables have heavy metal?
Asphalt is a hydrophobic material, it is impermeable, and almost insoluble in water, acetone, ether, dilute ethanol, dissolved in carbon disulfide, carbon tetrachloride, sodium hydroxide.
Q:How to identify carboxylic acid and anhydride
and phosphorus tribromide reaction to form bromide;
Q:What is cigarization?
Many people have a serious alcoholic misunderstanding that the longer the better alcoholization time, this is a beautiful misunderstanding, each cigar unique alcohol cycle is a lifelong pursuit of the mystery. For Cuban cigars, some support for 10 years after 8 years, you will be pleasantly surprised to find the cigar reached round mellow and, for example, Patagas, but some of the ten years will taste like chewing wax, cigars tend to death almost no taste.
Q:Are all carbon compounds all organic?
Not ah, like CO, CO2, carbonated, carbonate is not ah
