Under normal temperature and pressure, Heptafluoropropane(HFC227EA) is a kind of colorless gas, and is a compressed liquefied gas to be stored in culinders. Heptafluoropropane(HFC227EA) extinguishant is an ideral substitute of Halon 1301, and is clean, low poisonous, and has a good fire-protecting effect. It is mainly used in total-flood extinguishing system.

Q:Is the oxygen derivative of the hydrocarbon a non-methane total hydrocarbon?: Since it is a hydrocarbon, it is bound to be a hydrocarbon, and the oxygen derivative of the hydrocarbon is not a hydrocarbon! Therefore, even if the oxygen-containing derivative is volatile again, it is not a non-methane total hydrocarbon

Q:Why does the molecular atom compound do not belong to the life structure: Life structure is composed of CHO as the main element through the covalent bond of the combination of hydrocarbons and their derivatives, and you said the molecular atomic compounds are usually atomic or ionic bond

Q:What cells are composed of compounds: Protein and water

Q:Why does toluene not belong to the derivatives of hydrocarbons?: Hydrocarbon: sound tīng, is composed of two elements of carbon and hydrogen organic compounds known as hydrocarbons, also known as hydrocarbons. It reacts with chlorine, bromine, oxygen and other hydrocarbons to produce derivatives of hydrocarbons. Such as methane and chlorine in the light conditions of reaction to produce methyl chloride, dichloromethane, chloroform and chloroform (carbon tetrachloride) and other derivatives. The concept of derivatives is hydrocarbon and chlorine, bromine, oxygen and other reaction products. While toluene is not methyl and benzene, she is a whole noun is aromatic. Also known as aromatic hydrocarbons. Generally have one or more six-ring (benzene ring) with a special structure. The simplest aromatic hydrocarbons are benzene, toluene, xylene. There is also naphthenes. As the name suggests it is a ring structure. The most common is the five carbon atoms or six carbon atoms of the ring, the former called cyclopentane, which is called cyclohexane. The molecular formula of the cycloalkane is of the formula CnH2n. Cycloalkane is also called cycloalkane hydrocarbons. And alkanes. Is a carbon atom between the single bond phase chain hydrocarbon. Since the number of atoms that make up the hydrocarbon and hydrogen is different, the result is that the petroleum contains hydrocarbon molecules with large and small differences. Alkanes are named according to the carbon atoms and numbers contained in the molecule, and the number of carbon atoms is less than 10, from 1 to 10, followed by a, B, C, D, E, G, Alkane to say that the number of carbon atoms in more than 11, with the number that thank you to adopt

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

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:Other corals are because the color of the corals show colorful, why only the red coral is the exception of it? did not find the reasons for the big god to explain: Calcium coral is the main component of calcium carbonate, in addition to about 3% of magnesium carbonate and 1.5% to 4% of organic matter, and trace amounts of silicon and iron. The presence of organic matter increases the toughness of corals, making it better for processing and polishing. Calcium coral colors are mostly white or gray, but when it contains a considerable amount of different impurities, it is possible to show red, pink, orange, yellow, blue, purple and other colors. Therefore, by the living environment and many other factors, the same kind of coral can have different colors, and different types of corals and stars showing the same color. Red coral is really because of carotene.

Q:What are the inorganic compounds: The precise organics are defined as: hydrocarbons and their derivatives. The derivative is the product of the hydrogen atom H being replaced by other radicals

Q:Are the asphalt and peat kinds of vegetables have heavy metal?: Asphalt is a hydrophobic material, it is impermeable, and almost insoluble in water, acetone, ether, dilute ethanol, dissolved in carbon disulfide, carbon tetrachloride, sodium hydroxide.

Q:What is the hydrocarbon thing: Hydrocarbons can be divided into: open chain hydrocarbons (carbon atoms in hydrocarbon molecules in open chain) - saturated hydrocarbons - alkanes - unsaturated hydrocarbons - olefins and polyolefins (carbon - carbon double bonds, unstable) - alkynes and (Cyclopentane) - cycloalkene - cycloalkyne aromatic hydrocarbon - monocyclic aromatic hydrocarbon (benzene and its homologues) - fused ring aromatic hydrocarbons (Polycyclic aromatic hydrocarbons and their homologues) - polycyclic aromatic hydrocarbons (naphthalene, anthracene and other condensed ring aromatic hydrocarbons and their homologues) all hydrocarbons are hydrophobic, that all the hydrocarbons are not soluble in water and coal The main ingredients are hydrocarbons
