What is your favorite chemical element Inorganic and organic? Why?

Silver element. Because silver ions can be sterilized, silver is the metal with the best conductivity, silver is not as vulgar as **, it is not a world currency like platinum, it is not a mixture like jade, and it is not like diamond that can be synthesized casually. Silver feels good to the touch, cold but round, silver is cheap, and you can make a lot of things out of it, but it's still the world's currency.

Another point is that its atomic weight is 108, titanium is high temperature resistant, corrosion resistant, low density, known as space metal. Every time I see this name, I always feel like watching a science fiction movie. The naming of titanium is also interesting, the god Hercules in ancient Greek mythology Titan.

The favorite inorganic substance is copper sulfate. The copper sulfate solution is suitable for both shades and shades, and it is very blue and beautiful. In 1904, Meyer Eberhard obtained a white solid from the acid-catalyzed condensation product of glyurea and formaldehyde, which was only soluble in formic acid and concentrated sulfate, and his research was put on hold for a long time [1].

It was not until 1981 that Mock successfully obtained the crystallization formed by the combination of CB [6] and calcium ions from sulfuric acid containing calcium ions, and it was recognized for the first time that this cyclic molecule formed by multiple glycoura units connected by methylene bridges was recognized. Subsequently, in 2000, Kimoon Kim and Anthony Day separated CB from the acid condensation products of glyurea and formaldehyde respectively[5]-[8] (spit out a groove, Kim first published the article, and Day applied for a patent first, so now many groups of CB[N] still have to find Day to buy, and sell this openly and sigma-aldrich, and in 2002, Anthony Day isolated CB again, This structure is called gyroscane, or "gyrolane". This structure is called gyroscane, or "gyrolane".

Instantanene. As the name suggests, the molecule means "instantaneous". This is a typical rheological molecule with a constant internal COPE rearrangement, resulting in at least 10 possible isomers.

rhodium, a high school competition review metal, is very serious when I see platinum ***, so I see a lot of details. The solution of rhodium salts has a rosy color, and its English name comes from the Greek word "rhodon", which means rose. Helium, high cold, extremely small, liquid helium boiling point is, the second most abundant element in the universe, golden emission spectrum lines, no three-phase point, atmospheric pressure will not solidify no matter how it cools down, high-resolution NMR must Josephson junction, Squid helium-neon laser tube, the cheapest narrow linewidth laser source, middle school students can buy it casually.

At a certain point, if you continue to cool down, it will become a superfluid (bose einstein condensate), almost all atoms are in the same ground state energy, and the De Bo wave properties are superimposed, so that the whole system presents a macroscopic quantum effect. <>

Which of the following elements are commonly found in organic compounds? Flourishing.

a.Carbon Neden Notice.

b.Hydrogen. c.Oxygen.

d.Nitrogen. Correct Answer: ABCD

Organic matter is organic compounds, which are mainly composed of oxygen, hydrogen, and carbon. Organic matter is the material basis for the production of jujubes. Fats, amino acids, proteins, sugars, heme, chlorophyll, enzymes, hormones, etc., are all organic substances.

The metabolism of organisms and the genetic phenomena of organisms involve the transformation of organic compounds. In addition, many substances that are closely related to human life, such as oil, natural gas, cotton, dyes, chemical fibers, natural and synthetic medicines, etc., are also organic compounds. Relatively inorganic, the number of organic matter is large, up to several million.

Due to the similarity in composition, organic matter has many common things, for example, it can generally be burned, the thermal stability is relatively poor, the melting point is low, most of it is insoluble in water, and it is easily soluble in organic soluble celery and demolition agent.

Organics are organic compounds.

Organic compounds are mainly composed of oxygen, hydrogen, and carbon, and carbon-containing compounds, but do not include carbon monoxide, sock carbon, and substances ending in carbonate. Organic matter is the material basis for the production of life, and all living organisms contain organic compounds. Fats, amino acids, proteins, sugars, heme, chlorophyll, enzymes, hormones, etc.

The metabolism of organisms and the genetic phenomena of organisms are involved in the transformation of organic compounds.

Hello classmates, if the problem has been solved, remember that yours is my affirmation I wish you to gallop the Tongyuan horse

First, because one carbon atom can form four chemical bonds, it can not only combine the atoms of other elements, but also combine carbon atoms with each other to form relatively stable chemical bonds.

2. The carbon atoms in organic matter have a variety of three-dimensional spatial arrangement, most of which exist in the form of regular tetrahedron, and can also exist in planar triangular and linear structures.

3. There are five types of bonding of carbon atoms. Carbon atoms can be formed into five situations: single bond, double bond, triple bond, chain formation, and ring formation.

Organic matter refers to compounds containing carbon elements Inorganic matter refers to compounds that do not contain carbon elements Although carbon monoxide, carbon dioxide, carbonate and other substances contain carbon elements, the properties of these substances are similar to inorganic substances, and they are classified as inorganic substances Therefore, organic matter must contain carbon elements, but compounds containing this element are not necessarily organic substances Substances that do not belong to organic matter in the daily diet are: sodium chloride and water, substances that belong to organic matter, edible oil, and sucrose

So the answer is: carbon; Not necessarily; Sodium chloride; Water; Cooking oil; Sucrose

There are so many elements in organic matter, you have to tell what organic matter is, right?

Substance A is a common organic matter in life, which only contains three elements: C, H and O, and their mass ratio is 12:3:8, then N(C):N(H):N(O)=12

16 concentrated sulfuric acid.

Concentrated sulfuric acid

The nomenclature of this compound is:

4-chloro-2 phenylbutyraldehyde.

The parent is butyraldehyde, which is Cl at position 4 and benzene ring at position 2.

I have packed all the knowledge I have learned and mailed it back to the teacher, but I don't know
