FAQ

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

China's largest asphalt production base where

Asphalt material is divided into asphalt and tar asphalt two categories. Asphalt is divided into natural asphalt and petroleum asphalt, natural asphalt is the oil exudation surface after long-term exposure and evaporation of the residue; oil asphalt is refined processing of residual oil residue, the appropriate process to deal with the product The Tar asphalt is coal, wood and other organic dry distillation processing of the tar after re-processing products. Most of the asphalt used in the project is petroleum asphalt, and petroleum asphalt is a mixture of complex hydrocarbons and their nonmetallic derivatives. Usually the asphalt flash point between 240 ℃ ~ 330 ℃, the ignition point than the flash point of about 3 ℃ ~ 6 ℃, so the construction temperature should be controlled below the flash point.

Is carbon monoxide an organic gas?

Carbon dioxide is highly toxic. It is a strong ability to combine blood hemoglobin, which leads to cell hypoxia and suffocation. At present, if the trace carbon monoxide environment work, do not wear a gas mask and other necessary, it is recommended to eat more iron and calcium foods to reduce the harm to the body.

Will AsH3 (arsenic trioxide) is organic or inorganic

So the organic matter must contain the element is the C element

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;

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

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.

Chemical life network: chemical (inorganic reaction, organic reaction) is equal to the life of life reaction?

Research on the origin, preparation, structure, nature, change and application of elements, elements and inorganic compounds.For the comprehensive utilization of mineral resources, the production and research of inorganic raw materials and functional materials in modern technology are of great significance At present, inorganic chemistry is in the new period of vigorous development, and many edge areas are rapidly rising and the scope of research has been expanded. Inorganic synthesis, high - element chemistry, coordination chemistry, organometallic chemistry, inorganic solid chemistry, bio - inorganic chemistry and isotope Chemical and other fields.
