Refrigerant R410A(HFC32/HFC125)

R410A is a kind of refrigerant of surroundings-protection model, used in replacing R22&R502. It has a good nature of cleaning, low poison, mon-combustion, good-refrigeration and so on, and greatly used in air-conditioner.

Q: What are the gaseous states of the oxygen-containing derivatives of the hydrocarbons under the standard conditions?: Nitrogen derivatives are; dimethylamine;

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: Why the silicon hydride less, a lot of hydrocarbons. (Why did not you find silicon-based creatures) and why are so many oxides of silicon, little carbon oxides?: Silicon-based organic matter, oxidized to form silica, this thing is hard, very high melting point of atomic crystals, but the existence of solid on Earth

Q: What is the relationship between hydrocarbon and hydrocarbon derivatives?: The hydrocarbon is the parent of the organic compound, and the other various organic compounds can be regarded as derivatives of one or more hydrogen atoms in the hydrocarbon molecule being replaced by atoms or radicals of other elements.

Q: Is the system name of a hydrocarbon derivative named if the question can be named according to the nomenclature of the alkane?: Halogen can be named after the alkane, the other can not

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: From the molecular level, are not all the energy obtained from the redox reaction?: Because one to be recycled, and secondly to be converted into electricity

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: What is organic?: Simply refers to the organic ingredients containing organic ingredients. The real organic cosmetics are organic plants as the main raw material, do not add artificial spices, artificial colors, oil-free ingredients, the added preservatives and surfactants must be strictly limited, and the manufacturing process to comply with the relevant provisions, can not use animals Experiments and the use of radiation sterilization products. In general, the certification of organic skin care products must meet the following conditions: First, the organic environment, the closest growth of natural growth, production base (ie, the environment) are not damaged, water (irrigation water), soil (soil ), Gas (air) is not contaminated. Second, organic cultivation, no artificial fertilizer irrigation or artificial feed, without antibiotics, chemical insecticide, without genetic variants. Third, the organic processing and production projects, including the harvest after washing, finishing, packaging, processing, transportation, storage, sales and other sectors) did not subject to secondary pollution.

Q: How the most primitive life on earth is produced under what conditions: These macromolecules are not in the modern sense of the protein and nucleic acid polymer, but a variety of amino acids, nucleosides, phosphoric acid, carbohydrates and some other small molecules of the disorder of the polymer, when the nucleoside and phosphoric acid composition of nucleoside Acid, and gradually form a nucleotide chain, the formation of these nucleotide chain of the amino acid on the formation of the field of binding force, and then assembled peptide chain. Or by the combination of a variety of amino acids into peptide chain formed by the force field on the surrounding nucleus formation field binding effect, and then assembled the nucleotide chain, with the formation of peptide chain and nucleotide chain longer and longer , The molecular weight is growing, and ultimately the formation of nucleic acids and proteins, nucleic acid and protein formation is the product of interaction with each other, is generated at the same time.
