Specifications

1. stored in a cylinder
2. a kind of compressed liquefied gas
3. non-destructive to ozone layer in the atmosphere

Hexafluoropropane(HFC236fa)extinguishant stored in a cylinder is a kind of compressed liquefied gas, which is colorless, non-corrosive, non-conductive and non-destructive to ozone layer in the atmosphere. Hexafluoropropane (HFC236fa) extinguishant is an ideal substitute of Halon 1211, suitable to fill a protection, also suitable to the site having man of all flooding.

Q:NH4HCO3 and so have C atoms ah, why still inorganic: Organic matter is a general term for carbon compounds (except carbon oxides, carbon dioxide, carbonates, carbonates, bicarbonates, metal carbides, cyanides, thiocyanides and other oxides) or hydrocarbons and their derivatives. Organic matter is the material basis for life. The inorganic compound usually refers to a compound containing no carbon element, but a few carbon-containing compounds such as carbon dioxide, carbonic acid, carbon monoxide, carbonate and the like do not have the properties of an organic substance, and therefore such substances are also inorganic.

Q:Is steel not organic synthetic material?: Steel is a mixture, the vast majority of elemental iron, also contains other elements, carbon is mixed in the inside, and did not constitute a compound.

Q:Why not ah?: Ethylene is not a derivative of hydrocarbons, ethylene Chemical formula: CH2 = CH2

Q:Why does the hydrocarbon derivative make the bromine water fade and the hydrocarbon can not: As long as carbon and carbon double bonds and three hydrocarbons can be hydrocarbons

Q:Inorganic chemistry employment direction? Current research direction: Optical inorganic boring, and now are with rare earth elements and radioactive elements to do some material research. Or electrochemical. battery!

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:Is the number of hydrogen atoms in the hydrocarbon or hydrocarbon derivative molecule be even: The number of hydrogen atoms in the hydrocarbons containing carbon, oxygen and oxygen is also even.

Q:Carbon compounds (except inorganic carbon compounds), hydrocarbons and derivatives of the general term is?: Hydrocarbons and hydrocarbon derivatives

Q:Why can organic matter be unique in chemical substances? What is the nature of the C atom?: Organic carbon can be used in various architectures (ring, chain, short or long chain, twisted or planar aromatic or heterocyclic or naphthenes containing N / S / X halogen / P, etc.) Reaction mechanism (electrophilic addition, nucleophilic substitution, carbon positive ion intermediates, etc.). Due to the large negative carbon power is not great, the number of hybrid tracks can be 2 to 4 and not too much. For silicon, because of the electronegativity is less than hydrogen, resulting in silane hydrogen bonds in the biased hydrogen to make it easy to break, so silane in the air can be spontaneous combustion (not to mention disilane and above) The formation of compounds (similar to the alkyl) between the basic and hydrogen is so unstable that other similar compounds are difficult to stabilize.

Q:Organic chemistry studies the performance of hydrocarbons and their derivatives, either right or wrong: Correct
