Dioxy is used in the method of making pills and pills. "Tiangong Wuwu", it has a wonderful use in the Dan family's system.
The Dan family's pill, often with dioxy to help it burn, can make the fire flourish. In the process of making pills, if you want to make the stone quickly react and fuse, to achieve exquisite melting, dioxy is indispensable. For example, if you use carbon fire to make gold stone, add dioxy to it, which can make the carbon fire burn more vigorously, accelerate the melting of the stone, and improve the gold. This is the use of dioxy to help the fire, so that the fire is fierce, so as to achieve the exquisite production of the Dan family.
In the field of pills, dioxy also has strange effects. Those who are ancient, observe that it can help breathing. If a person is unable to rest and the chest is relieved, dioxy can be used to calm their breathing. Because dioxy is necessary for their life, it can promote the movement of blood, blood, and five internal organs. In case of shortness of breath in patients, dioxy can be introduced in a simple way, which can make the patient's breathing normal and the spirit also vibrate.
In addition, dioxy can also be used in some special processes. It can make the ingredients of the compound easier to precipitate, fuse, and increase the effect. Or it can be integrated, making it more suitable for the treatment of diseases.
In other words, dioxy was an important function in the ancient alchemy field, with its characteristics of supporting combustion and beneficial breathing, shadows, etc. It was an important function for the alchemy family to cure diseases and save people, and to provide assistance.

Dioxygen is also gas, colorless and odorless, slightly soluble in water, heavier than air. Its nature is mild, under room temperature and pressure, it is stable and not impatient, but in a specific environment, it can also show its characteristics.
First of all, its physical rationality. Dioxygen is gas in normal state, liquid in condensation, and can be solidified under very cold. It is called dry ice. Dry ice is like frost and snow, without liquid state, it directly turns into gas, which is called sublimation. Although the solubility of dioxygen in water is slight, it is also soluble. Its dissolution is also combined with water to produce carbonic acid, so soda has a sour meaning. Furthermore, because it is heavier than air, it often accumulates in low places, such as deep gullies and caverns. If people rashly enter it, they may be in danger of suffocation.
Second, on its chemical properties. Dioxygen does not support combustion, and it is not flammable by itself, so it has a good effect on extinguishing fire. Because it can isolate the contact between oxygen and combustible materials, the fire is extinguished. In addition, green plants rely on dioxygen for photosynthesis, inhaling dioxygen and exhaling oxygen, which is the key to the natural oxygen and dioxygen cycle. In industry, dioxygen can be used to make alkali, urea, etc., and has a wide range of uses.
In the environment, dioxygen is also crucial. The right amount is necessary for the growth of all things. However, with the decline of the world and the prosperity of industry, the emission of dioxygen has increased sharply, resulting in the gradual appearance of the greenhouse effect. Global temperatures are rising, glaciers are melting, sea levels are rising, and ecological imbalances are all harmful to excessive dioxygen.
In a word, dioxygen is both beneficial and harmful to our lives. Use it well, it is a blessing; use it improperly, it is a scourge. Be careful, so that dioxygen can be used to its advantage and avoid its harm, so as to achieve a harmonious coexistence between nature and human beings.

The dioxane octahedron has different chemical properties and is related to many chemical changes. Today, I will talk about it in detail.
Dioxane octahedron has an orderly arrangement of oxygen atoms in it, forming an octahedral shape. Its structure is stable and it shows unique properties in chemical reactions.
In terms of its oxidation properties, it is quite impressive. Oxygen atoms have strong electronegativity, and in the state of dioxane octahedron, they are more oxidizing. It can often increase the valence state of other substances and lead to oxidation reactions. If it encounters reducing substances, it can be phased with them, such as metal elementals, which can be oxidized to form metal oxides. This change is due to the fact that dioxane wants to achieve electron stability, so it grabs electrons from other substances.
Furthermore, its stability is also important. Due to the delicate structure of the octahedron, the bond energy distribution between the atoms is reasonable, resulting in strong overall stability. However, if external conditions change, such as high temperature, strong acid and alkali environments, it can also break its stability and cause chemical changes. Under high temperature, the structure may loosen, the activity of oxygen atoms increases greatly, and the tendency to participate in the reaction also increases.
Dioxy octahedron also has unique performance in acid-base systems. In acidic environments, or interacting with acid ions, it can change the direction and rate of chemical reactions; in alkaline environments, it can also react with hydroxide ions, etc. The specific reaction formula varies depending on the system and associated substances.
Its solubility also has characteristics. In a specific solvent, it can be dissolved, and after dissolution or dissociation equilibrium, which affects the chemical properties of the solution.
In short, the chemical properties of dioxane are determined by its unique structure. It is unique in terms of redox, stability, acid-base and dissolution. It is of great value in the research and application of chemistry and is a key factor in many chemical processes.

First, in the ancient method, burning charcoal to make a fire was described as follows:
First, in the ancient method, burning charcoal to make a fire, in a dense room, the charcoal burned and burned, and the oxygen was depleted. However, this method is dangerous, the room is less oxygen, and people are easy to suffocate, which is not a good method.
Second, using carboniferous materials, carboniferous, coal is also. Burning it in the middle of a fire also generates dioxy. This was often used in ancient smelting and cooking. However, carboniferous burning is too much, too heavy, and the carboniferous is rare, which is not a long-term strategy.
Third, today's new law, nationalization method. With carbonated acid, dioxy can be obtained. Its reaction speed is fast, and it is easy to collect. Equation: $CaCO_ {3} + 2HCl = CaCl_ {2} + H_ {2} O + CO_ {2}\ uparrow $.
Fourth, on the work, calcined limestone is also a common method. Limestone is carbonated. Under the high temperature, it decomposes to produce dioxy. Its inverse formula: $CaCO_ {3}\ stackrel {high }{=\!=\!=} CaO + CO_ {2}\ uparrow $. This is the way to produce a large amount of dioxy, so lime is also useful.
Fifth, the biological process also involves dioxy. Such as biological respiration, oxygen inhalation and dioxy, then this is not the method of production, and it is one of the natural processes.
It is the same, the ancient method and the current method exist, each has its advantages and disadvantages, and the required amount, use, cost, etc. are used for good.

Dioxy is in the city, and its price cannot be covered by a single word. The market conditions are ever-changing, and the price is also changing, which is related to supply and demand, the current situation, and the right place.
I have heard of various cities, and their prices may vary. When the production is abundant, the supply exceeds the demand, and the price may be cheap. If the weather is unfavorable, and the production is not abundant, but there are many who need it, the price will be high.
The market in ancient times was easy, although it was not as complicated as it is today, it is the same. In the past, trade goods were also priced according to their scarcity. Dioxy flowers are widely used and are needed in all industries, so their price is important to everyone. < Br >
In nearby cities, I heard that this summer, the production was abundant but the demand did not increase sharply, and the price was about three dollars per catty. In autumn, the weather is getting cooler, and the price of those who use it is slightly reduced, and the price is also reduced, about two and a half dollars.
However, in distant cities, or due to difficult transportation on the road, the price is often high. Or there are other local feelings, so that the supply and demand are different from those in nearby places, and the price is also different. Or in some cities, because of its use, although the production is abundant, the price is still stable, about seven dollars for three dollars.
Looking at it, dioxy is in the market, and the price is about two and a half to three dollars for seven dollars. However, this is only a momentary observation, and changes in the market outlook must still be observed depending on the movement of things.
