For those who are in the sixth grade, there is no reason for their materiality to be studied.
For those who are in the sixth grade, there is no reason for them to be, no reason for them to be, no reason for them to be, no reason for them to be, no reason for them to be, no reason for them to be, no reason for them to be, no reason for them to be, no reason for them to be, rain, dark, and bright. For those who are in the sixth grade, their nature is heavy and heavy, and they often drop but do not rise. For those who are in the sixth grade, they are in the ascension and warmth of their nature. If they are in the spring and summer, they are in the spring and summer, and the nature of fire is close, and they are in the ascension but do not fall.
For those who are in the spring and summer, they are not living, and they are often flowing. Their nature is good and scattered, and they can drum up The physics of light is like the flow of empty air, which can move things, whether it is rapid or slow, and the size of its force, because of the speed. Rain is the fall of water, and the nature of the underworld is natural. Its shape and liquid can nourish things, and it can also be used to make. Caused by condensation, it falls on the ground due to the melting of cold.
The obscure one, the dark and unknown image, its physics is like the sun, the long time, it can hinder the, so that the shape of things can be discerned. The bright one is like the sky, the day is like the sky, the light shines, and the things are. The physics of light, in the abundance of light, can make things clear and can be made, its nature is transparent, and it is dark.
These six kinds of things are rational, and they interact with each other. The rain is obscure, and the rain is obscure. Sympathy, and the generation of rain is obscure and obscure. It is in the world, and it is followed. It becomes a wonderful place of nature, and the things are born and lived.

Ammonia is a common gas. Its chemical properties are quite unique, and I would like to describe them in detail for you.
First of all, its alkalinity. Ammonia is very soluble in water and generates ammonia monohydrate. This is a weak base, which can partially ionize hydroxide ions, so the ammonia solution is alkaline. For example, the "Chemical Classic" says: "Ammonia enters water and turns into a base, which can make phenolphthalein appear red." This is because phenolphthalein turns red when it meets alkali. And ammonia can react with acids to form ammonium salts. If ammonia meets hydrogen chloride, it is combined into ammonium chloride, and the two meet in gas phase, instantly forming smoke, like a fairy cloud, which is very wonderful.
Second on its reductivity. Nitrogen in ammonia molecules is -3 valent, which is the lowest price of nitrogen, so ammonia gas is reductive. Under certain conditions, ammonia can be oxidized by oxidants. If platinum is used as a catalyst, ammonia can react with oxygen to form nitric oxide and water. This reaction is a key step in the industrial production of nitric acid, just like the magic method of alchemy. Through this reaction, the potential of ammonia gas is developed and turned into the cornerstone of nitric acid.
Furthermore, ammonia can participate in coordination reactions. Nitrogen atoms in ammonia molecules contain lone pairs of electrons, which can form coordination bonds with certain metal ions. If ammonia gas is introduced into the copper sulfate solution, the blue precipitation of copper hydroxide is formed first, and ammonia gas is introduced, and the precipitation dissolves to form dark blue tetraammonium copper ions. This phenomenon is like a magic change, which is amazing.
And ammonia can react with active metals. At high temperatures, ammonia can react with active metals such as magnesium to replace hydrogen. This is also the unique property of ammonia, such as warriors and strong generals, each performing its own abilities.
In summary, the chemical properties of ammonia are diverse, or alkaline, or reduced, or coordinated, or can be replaced. In the world of chemistry, such as the stars, it contributes extraordinary power to the chemical industry and scientific research.

In the field of engineering and technology, it can be used as an anti-chemical medium, such as grease, to increase its efficiency and improve its properties, so that it can be used in food and engineering. It also has the importance of synthesis, helping to create a variety of materials and plastic materials.
In the field of energy, it can be used as fuel, which can reduce energy and reduce dyeing. It has the potential to solve the energy dilemma and improve the environment.
In the field of metallurgy, it can be used as a raw material to improve the quality of gold, such as oil, oil, and high-quality materials.
In the chemical industry, the synthesis of ammonia is the foundation of nitrogen fertilizer, which is the foundation of nitrogen fertilizer. It is also involved in the production of methanol and other chemical products, and supports the chemical industry.
It is also used in the analysis of chemical products, and can be used for qualitative, quantitative, and analytical materials.
And in food processing, it can be used for the hardening of oils and fats, the production of margarine, etc., to increase the quality and taste of food.
Of course, the four fields are used in engineering and technology, energy, metallurgy, chemical industry, analysis, food industry, etc., all of which are of great use.

Mercury is a highly toxic thing, and the way to prevent it has been there since ancient times. Although the "Tiangong Kaiwu" does not describe the prevention of mercury poisoning in detail, there is a lot of wisdom from predecessors in related labor.
First, the working environment should be well ventilated. In the place where mercury is mined, an open and ventilated place should be selected so that the mercury gas can be easily dissipated. If you are indoors, you should also open more windows to allow air circulation. For example, in the alchemy room where mercury is smelted, an air duct must be set up to prevent the toxic gas from accumulating.
Second, protective equipment is indispensable. People who collect mercury should cover their mouth and nose with a damp cloth to slightly prevent mercury gas from being inhaled. Gloves can also be made of leather or thick cloth to prevent mercury liquid from staining the skin.
Third, dietary conditioning can be assisted. Regular consumption of pig blood, mung beans, etc., can help detoxify. Pig blood can clear the filth of the stomach, mung beans have the power of detoxification, and laborers often eat it, which is beneficial to the body.
Fourth, after working, you must clean your body and change your clothes. After mining mercury, quickly wash your body with saponin water, change your clothes, and place the clothes stained with mercury alone. Do not mix with regular clothes to avoid mercury gas residue.
Fifth, moderate labor and rest. Do not engage in mercury-related labor continuously for a long time, and should rest in a timely manner to give your body a chance to recover to reduce mercury poisoning.
Although the ancient prevention method may not be as complete as it is today, its emphasis on ventilation, protection, diet and other concepts also provides a useful reference for future generations to prevent mercury poisoning.

For hexapyridine, there are chemical compounds, which are dangerous to a certain extent. If it is used, it is generally safe and cannot be ignored.
The first heavy pass. Where it is used, it must be good and make the room flow faster. Hexapyridine Such as wearing anti-corrosive gloves, so as not to touch the skin, causing the skin to burn, sensitive; anti-corrosive work clothes, the whole body; wearing anti-ocular, ocular eyes, if inadvertently into the eyes, can cause serious damage to the eyes. During operation, it is appropriate to do so and avoid leakage. Pour and move away, especially pay attention.
Furthermore, store properly. It should be stored in the dry, dry, pass, fire source and source. Because of its flammability, it will explode in case of open flame, high combustible. And store it in parts such as oxidation and acid to avoid mixing, so as to prevent strong reaction. The storage container is well sealed to prevent leakage.
Also, first aid is not allowed. If the skin is connected, quickly wash it with a large amount of flowing water, and wash it with soapy water. If inhaled, move to the new air immediately to keep the respiratory tract open; if breathing is sleepy, oxygen is lost; if breathing and heartbeat stop, the heart and lungs will be damaged, and it will be delivered as soon as possible. For eaters, use enough water to induce vomiting, and also send it as soon as possible.

<, use hexapyridine, it is safe to do so, and do not slack off. The measures are all taken to ensure safety.
