Stearic Acid 1820

Q:What is carbohydrate? What is organic? What is it?: 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: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:Are hydrocarbons are hydrocarbons and that alcohols? Is it carbon dioxide?: Is a hydrocarbon derivative.

Q:How to do it? Solve Inorganic Chemistry: Inorganic chemistry is one of the earliest disciplines in the development of chemical science. It undertakes a major task of studying the composition, structure, properties and reactions of all elements and elements (except hydrocarbons and derivatives). The current development of inorganic chemistry has two distinct trends, that is, in the breadth of the broadening and depth of the advance. It is the three pillars of modern civilization

Q:Will AsH3 (arsenic trioxide) is organic or inorganic: AsH3 (arsine trihydride) is not containing C element

Q:Is polyethylene a derivative of hydrocarbons?: The definition is yes

Q:Is carbon monoxide an organic gas?: Carbon dioxide is highly toxic. It is a strong ability to combine blood hemoglobin, which leads to cell hypoxia and suffocation. At present, if the trace carbon monoxide environment work, do not wear a gas mask and other necessary, it is recommended to eat more iron and calcium foods to reduce the harm to the body.

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:Carboxylic acid and ester can form isomers. What are the conditions?: The general formula for the carboxylic acid is RCOOH, and the general formula for the carboxylic acid ester is R? COOR? (R? May be a hydrogen atom). If the total number of carbon atoms in the R group in the carboxylic acid is the same as the total number of carbon atoms of the two R groups (R + R?) in the carboxylic acid ester and the total number of R atoms in the carboxylic acid is higher than that of the carboxyl groups R & lt; 1 & gt; R & lt; 2 & gt;), both of which constitute isomers, such as acetic acid and methyl formate, butyric acid and ethyl acetate, phenylacetic acid and methyl benzoate are all isomers.

Q:Does the carboxylic acid react with the Grignard reagent?: Reaction. Grignard reagent is an organic strong base, first and the acid reaction of carboxylic acid to produce magnesium salt, and sometimes further nucleophilic attack, control conditions will get different products, but the first acid-base reaction is unavoidable.
