R407C is a non zeotropic HFC replacement blend mainly used as a replacement for R-22 in air conditioning applications. (split systems, packaged air-conditioners or water chillers).
- Q: What are the gaseous states of the oxygen-containing derivatives of the hydrocarbons under the standard conditions?
- Oxygenated derivatives are: methyl ether, methyl ethyl ether, formaldehyde, ethylene oxide;
- Q: Sugar, fat, and so on a variety of organic matter is full of different units of the heat of the small box. (Save the heat the most efficient, the least loss of heat the most practical and most economical box).
- Inorganic matter with carbon after, as if with their own ideas, began to build their own. So slowly evolved into a complex organic matter
- 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.)
- Q: The role of aromatic hydrocarbons
- Two cases: First, the name of monocyclic aromatic hydrocarbons, usually benzene ring for the mother, alkyl as a substituent. Second, the structure is more complex aromatic hydrocarbons, usually based on the hydrocarbon base, benzene ring as a substituent. Xylene, 2-methyl-3-phenylpentane, diphenylmethane, etc. For the naming of multifunctional compounds, attention is given to the priority order of the functional groups. The priority is preceded by the parent, usually: cations, COOH SO2H, COOR, COCl, CONH2, CN, CHO, CO, OH, SH, NH2, alkynes, alkenes, ethers, X, NO2, etc. [2]
- Q: Inorganic chemistry employment direction? Current research direction
- Inorganic chemistry is the science of the composition, nature, structure and reaction of inorganic matter, which is the oldest branch of chemistry. Inorganic substances include all chemical elements and their compounds, except for most of the carbon compounds. (In addition to carbon dioxide, carbon monoxide, carbon disulfide, carbonates and other simple carbon compounds are still inorganic substances, the rest are organic matter.) Inorganic chemistry is in addition to hydrocarbons and their derivatives, the nature of all elements and their compounds And their reaction to experimental research and theoretical interpretation of science, is the development of the discipline of the earliest branch of a discipline.
- 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: NH4HCO3 and so have C atoms ah, why still inorganic
- Organic definition is not all elements, if only look at carbon atoms, then graphite and carbon dioxide are also areas of organic matter, so this is not the case. In general, organic matter is defined as containing atomic elements, which can be combusted, low density, low melting point, strong volatility, poor solubility in water, etc., which are composed of carbon atoms and covalent bonds.
- Q: Rush! Hydrocarbon and hydrocarbon derivatives system information includes chemical formula, common name, Chinese name and so on
- The system is too difficult to summarize. Too much.
- Q: Organic chemistry, naming of derivatives containing oxygen (hetero) atomic bridged cyclic hydrocarbons
- Pro-butylbenzene ethane
- Q: Why artemisinin and its derivatives in the molecular structure of a peroxide chain, the chemical properties are more stable?
- Heated to more than sixty degrees on the decomposition of things how to say that stability ...
