Q:Is grease a polymer compound? Is it a derivative of saturated hydrocarbons?

Grease is not a polymer, a hydrocarbon (not necessarily a saturated hydrocarbon) derivative,

Q:What is the difference between crude oil and asphalt?

Asphalt is the residue of crude oil

Q:Compare the difference between London smoke and Los Angeles photochemical smog

Los Angeles photochemical smog nitrogen content and hydrocarbons and derivatives more, mainly close to the car exhaust. Foggy London situation related to coal, soot solid particles and sulfur oxide more. Foggy London is more bleak, and Los Angeles is more toxic.

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:What is the most primitive person on earth?

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.

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 is the proportion of hydrocarbons synthesized by Fischer-Tropsch Synthese in liquid fuels consumed by Nazi Germany? What are the proportions of these hydrocarbons as an industrial raw material into their military industry, in addition to fuel? At that time, did the Fischer-Tropsch preparations occupy an important position in Nazi Germany's military industry or heavy industry?

The FT synthesis method is a coal liquefaction technique under an iron-based catalyst (conventional FT method is a cobalt-based catalyst). Mainly syngas (CO and H2-based) saturated alkylation technology.

Q:Sodium can be used to identify derivatives of hydrocarbons

The alcohol reacts with sodium. (Such as phenolic C6H5OH, cresol CH3C6H4OH, etc.), carboxylic acids (such as formic acid HCOOH, acetic acid CH3COOH, etc.) (description: hydroxyl groups in the carboxylic acid are hydroxyl groups in the carboxyl group) and hydroxyl groups containing polyhydroxyaldehydes and polyhydroxy ketones Such as glucose, fructose, etc.)

Q:Ionic compounds, covalent compounds, electrolytes, non-electrolytes, which are both compounds and inorganic compounds

The covalent compound is a compound molecule composed of a common electron pair between atoms. When two nonmetallic elements (or inactive metal and nonmetallic elements) are combined, one or more electrons are formed between the atoms, and the electron pair is attracted by two nuclei, and the two atoms are common , So that two atoms form compound molecules. For example, hydrogen chloride is a hydrogen atom and chlorine atoms each with the outermost layer of electrons to form a common pair of compounds composed of compounds. Non-metallic hydrides (such as HCl, H2O, NH3, etc.), non-metallic oxides (such as CO2, SO3, etc.), anhydrous acids (such as H2SO4, HNO3, etc.), most organic compounds (such as methane, Are covalent compounds. Most covalent compounds in the soli

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.
