- 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:What are the characteristics of organic compounds?
- Organic compounds are usually referred to as carbon-containing compounds, or hydrocarbon-containing compounds and their derivatives are collectively referred to as organic matter. Organic compounds are generally insoluble in water and soluble in organic solvents with lower melting points. The vast majority of organic matter heat easily decomposed, easy to burn. The reaction of organic matter is generally slow and often accompanied by side effects, and there are many kinds of organic compounds, which can be divided into two major categories of hydrocarbon and hydrocarbon derivatives. According to the organic groups contained in the functional groups, divided into alkanes, alkenes, alkynes, aromatic hydrocarbons and alcohols, aldehydes, carboxylic acids, esters and so on. According to the organic carbon molecular structure, can also be divided into open chain compounds, carbocyclic compounds and heterocyclic compounds three categories.
- Q:What is the difference between hot and cold asphalt?
- Grandmother next door aunt is the street to sell stewed meat, a child often see her burning a pot of hot asphalt pork hair, black asphalt boiled immediately leaching in the meat, and so dry quickly pull it down, pork will Change very clean and white, clean the meat will be directly thrown into the pot halogen system, this method relative to the traditional plucking save time and effort a lot. Here, please bloggers blame me to come to funny, because the end of the story is not funny, that aunt's little sister in the sixth grade when suffering from leukemia away, adults say with her home burning asphalt There are relationships, eighteen years later, and she only a few side of the edge of the I actually remember the full name of her sister, her looks, the tone of her voice, we played the game and we were a very curious In the asphalt pot to see the scene of pig hair ... ... hope that each parents do not ignore the child's growth in the small problem.
- Q:Peracetic acid is not
- A series of compounds produced by the substitution of hydrogen atoms in other molecular or atomic groups as hydrocarbon derivatives, peroxyacetic acid is CH3COOOH, and should be considered
- 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:Such as the title, the personal feeling of chemical transliteration of Chinese transliteration can be done so easy to write, weird name in addition to keep the high point, no good, but rather affect the people's understanding of medicine and memory, contrary to the text to facilitate the exchange of memory Original intention
- 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:What is the difference between organic matter and inorganic matter?
- Organic compounds in addition to a few, can generally burn. Compared with inorganic matter, their thermal stability is relatively poor, the electrolyte is easy to heat decomposition. The melting point of organic matter is low, generally not more than 400 ℃. The polarity of organic matter is very weak, so most of the water is not soluble. The reaction between organic matter, mostly intermolecular reactions, often requires a certain activation energy, so the reaction is slow, often requiring catalyst and other means. And the reaction of organic matter is more complex, under the same conditions, a compound can often be several different reactions at the same time, generate different products.
- Q:Junior high school chemistry knowledge, please explain what is organic compounds, inorganic compounds.
- 3. Organic matter is generally insoluble in water, soluble in organic solvents, low melting point. The vast majority of organic matter heat easily decomposed, easy to burn. The reaction of organic matter is generally slow and often accompanied by side effects.
- Q:What is the relationship between hydrocarbon and hydrocarbon derivatives?
- Hydrocarbons, which are composed of two elements, carbon and hydrogen, are called hydrocarbons and hydrocarbons. It reacts with chlorine, bromine vapor, oxygen, etc. to produce hydrocarbons.
- Q:Is the number of hydrogen atoms in the hydrocarbon or hydrocarbon derivative molecule be even
- Other hydrocarbon derivatives are not necessarily, such as halogenated hydrocarbons containing odd halogen molecules, containing an odd number of N atoms containing C, H. O, N four elements of the compound, their number of hydrogen atoms are odd.
