What is the Chinese name of this compound?
This compound is called mercury. Mercury is one of the chemical elements, its chemical symbol is Hg, and its atomic number is 80. Under normal temperature and pressure, mercury presents a liquid state, and is the only liquid metal, so it is also known as "mercury".
Looking at its physical properties, mercury has a metallic luster, is silver-white, has a soft texture, and has a high density, reaching 13.59 grams per cubic centimeter. Its melting point is very low, -38.87 ° C, and its boiling point is only 356.6 ° C. Mercury has good electrical conductivity, but its thermal conductivity is inferior to that of most metals.
Mercury's chemical properties are relatively stable. At room temperature, it does not react with oxygen. When heated, it combines with oxygen to form mercury oxide. Mercury can be alloyed with a variety of metals, and this alloy is called amalgam.
Mercury exists in nature mainly in the form of mercury sulfide (cinnabar). To obtain mercury, cinnabar is often heated and roasted to decompose it.
Mercury has a wide range of uses. In ancient times, it was often used in alchemy. Many alchemists wanted to use the properties of mercury to refine elixirs of immortality. Although they did not get what they wanted, they also promoted the ancient people's understanding of mercury. In the field of medicine, mercury compounds were used to make medicines, but due to the toxicity of mercury, they are rarely used today. In industry, mercury is often used as an electrode and plays an important role in battery manufacturing. In the manufacture of thermometers and barometers, mercury has remarkable characteristics of thermal expansion and contraction, and is easy to observe in liquid state, making it an excellent material.
However, it should be noted that mercury and its compounds are toxic and can invade the human body through the respiratory tract, digestive tract and skin, damaging the human nervous system, kidneys and other organs. If mercury leakage occurs accidentally, it needs to be properly handled in time to prevent mercury volatilization and human poisoning.

What are its physical properties?
The physical properties of an utensil are related to its shape, quality and properties. Viewed from the perspective of "Tiangong Kaiwu", the physical properties of utensils are as follows.
When it comes to shape, the appearance of utensils is different. Such as the retort, its shape is different, or the belly is round and the mouth is closed, or the body is square and open. The difference in this shape comes from the need for function. The kettle is used for cooking, and the round belly is conducive to uniform heating and accelerated cooking; the retort is used for steaming, and the open mouth is convenient for steam circulation, so that the food is cooked quickly. And the shape of the utensils is also related to the skill of craftsmanship. Those who are skilled in craftsmanship can make a strange shape, with smooth lines and harmonious proportions, which is both practical and aesthetic.
As for quality, it is the foundation of utensils. Different materials have different properties. If you take metal as an example, gold is soft and precious, with good ductility, and is often the choice for jewelry. It can make exquisite and gorgeous utensils; iron is strong and tough, and can be cast into swords and agricultural tools. Swords are made of iron, and the sharpness is incomparable. Agricultural tools are made of iron, and they are durable and lasting. And stone utensils are hard and brittle. Those that are strong are like granules, which can be used as cornerstones and carry heavy objects without destroying them. Those that are brittle are like shale, or can be carved into small pieces, but they are easy to fold under force.
Those that are sexual cover many characteristics of utensils. The nature of heat is related to heat transfer and heat dissipation. In terms of cookware, copper heat transfer speed can make food heat quickly and save fuel; pottery dissipates heat slowly and can keep warm, so that food is not cold for a long time. Although the properties of electricity have not been studied in detail in ancient times, it is known that some materials are insulated and some are conductive. And the utensils have corrosion resistance, gold and silver are not easy to rust, and can be stored for a long time without damage; iron is easy to corrode in contact with water, so it needs to be protected. It also has elasticity, hardness, etc. Bamboo and wood are elastic, and can be made into bow and crossbow bamboo chairs, which have a degree of flexion and extension; jade has high hardness and is difficult to carve, but the finished product is smooth and radiant, and durable and wear-resistant.
The physical properties of utensils are their appearance, their The three are interrelated, and together they achieve the use and beauty of utensils. In the craftsmanship of Hundred Workers, they all need to be carefully investigated in order to obtain the wonders of utensils and become the work of creation.

What are its chemical properties?
The chemical properties of a substance are related to its properties in chemical reactions and the laws of change involved. Discussed in detail today.
One, flammability. This is a significant chemical property of many substances. Such as common firewood and coal, under suitable conditions, can react violently with oxygen in the air to release light and heat. This is the process of combustion. The essence is the oxidation reaction of substances and oxygen. This property is widely used in daily life and industrial production, such as burning coal for heat and power generation.
Its two, oxidation and reduction. Oxidative substances tend to acquire electrons in the reaction, so that other substances oxidize. Take oxygen as an example, it can make metals rust. This is the process of oxygen oxidizing metals. Reducing substances, on the other hand, lose electrons to reduce other substances. For example, hydrogen can reduce copper oxide, hydrogen loses electrons, and copper oxide gains electrons and is reduced to copper.
Third, acid and alkali. Acids have specific chemical properties. For example, they can turn purple litmus test solution red and neutralize with bases to form salts and water. Common hydrochloric acid and sulfuric acid can react with active metals to generate hydrogen. Bases can turn purple litmus test solution blue and neutralize with acids. Sodium hydroxide, calcium hydroxide and other bases are used in industry and life. For example, calcium hydroxide can be used to improve acidic soils.
Fourth, stability. Some substances are chemically stable and do not react easily with other substances. Such as rare gases, because of their stable atomic structure, it is difficult to participate in chemical reactions under normal conditions, so they are often used to protect gas to prevent other substances from being oxidized or other reactions.
Fifth, corrosive. Certain strong acids, alkalis and other substances are corrosive and can damage the structure of other substances. Concentrated sulfuric acid is highly corrosive. Accidental contact with the skin can dehydrate and carbonize the skin, causing serious damage.
The above are all common chemical properties of substances. They are of great significance in scientific research, industrial production, and daily life. They need to be understood and used carefully.

"Tiangong Kaiwu" was written by Song Yingxing in the Ming Dynasty, detailing all kinds of technological techniques, which are applied in many fields.
In the field of agriculture, the book contains farming methods in detail. For example, on rice farming, from sowing and raising seedlings to field management, it is described in detail. "The earliest period of wet planting, before the spring equinox, is called social planting", indicating the sowing season. And talking about the use of various fertilizers, "For soil with cold pulp, it is appropriate to dip the ashes in the roots of the seedlings, and the lime floods the seedlings." This is to improve soil fertility and facilitate crop growth, which is of great significance to agricultural production guidance.
In the textile field, "Tiangong Kaiwu" has a detailed record of sericulture and silk weaving techniques. " Where there are silkworm species, only those who live in cocoons. There are those who harvest late moths and give birth to sons and moths in the near future, and they are not available. ", the importance of seed selection. From reeling and winding, to the structure and operation of looms, there are drawings and text descriptions, which promote the inheritance and development of textile skills and provide a basis for the improvement of the textile industry.
In the field of ceramics, the book describes the process of porcelain making, from the selection of raw materials" from Wuyuan and Qimen Mountains "to billet making, glazing, and firing." Where white soil is called chalk, it is used for exquisite utensils of pottery ", which clearly shows the characteristics and uses of raw materials, and helps a lot to improve the technology of the ceramic industry.
In the field of metallurgy, the book details the iron and steel smelting and casting Where iron is merging and ripe, it is raw if it is not fried out of the oven, and it is ripe if it is fried. "Explain the difference between pig iron and wrought iron. Also talk about the method of casting bells and tripods," where a bell is cast, the higher is copper, and the lower is iron ", providing specifications for the production and operation of the metallurgical industry.
In addition, in the fields of papermaking, salt making, sugar making, etc.," Tiangong Kaiwu "also has detailed accounts, providing reference for practitioners in various industries, promoting the inheritance and progress of traditional handicraft technology, and having a profound impact on the development of many industries in ancient China.

What is its preparation method?
The method of making the utensil is quite complicated, and I will describe it in detail.
The first good material is obtained, and its quality must be firm and tough, and good wood is appropriate. Cut it, carefully choose those with straight texture and no joints and no defects. This is the foundation of the utensil. Then cut the wood as a section, measure the size according to the shape of the utensil, and cut it with a saw to ensure that the size is accurate and unpleasant.
Then carve. First outline the contour of the utensil with ink lines. This is the blueprint of the utensil, which is related to the beauty of the shape. The craftsman handles the knife, transporting the catty into the wind, engraving according to the line, or round or square, or curved or straight, all need to fit the design. When engraving, the force should be uniform, and the weight should be moderate, so that the lines are smooth and the shape is natural. In the details, it needs to be more careful, such as engraving the petals of flowers, which must be lifelike; the hair of the eagle beast, when the roots are clear.
Then polish. Grind it gradually with a thick sand skin. If you first use a coarse one, remove its edges and roughness; then change the fine sand to make the surface as smooth as a mirror. The work of grinding is not tired of its essence until you caress it with your hands, there is no obstruction, and you can see it with your eyes, and you can learn from people.
If you make a metal tool, there is also a different way. Melt the metal first, put it in a crucible, set it on fire and calcinate it, and wait for it to become Control its heat, do not make it too prosperous or too weak. If it is too prosperous, the metal will be fragile, and if it is too weak, it will be difficult to form a liquid state. And then pour into the mold, and the shape of the mold depends on the device, or for the tripod, or for the jue, or for the plate. Wait for it to cool and solidify, remove the mold and come out, then trim it, remove its burrs, refine the edges, and make the shape of the tool regular.
The method of making a tool cannot be achieved overnight. It requires a craftsman's heart as fine as hair, skilled, and honed over time to become a beautiful tool for the world to appreciate.

What are the chemical properties of 1-bromo-2-chlorobenzene
Mercury is cold in nature and heavy in quality. It is a liquid at room temperature, resembling the flow of silver, so it is also known as "mercury". It is highly toxic and should be used with caution.
Mercury has unique chemical properties. Its chemical activity is relatively low, and it is not easy to react easily with most common substances at room temperature and pressure. However, in case of strong oxidants, such as pure oxygen and under heating conditions, mercury can combine with it to form mercury oxide. In this reaction, mercury changes from elemental substance to compound, and its valence state also changes.
Bromine is the only non-metallic element that is liquid at room temperature and pressure. Its color is red-brown, with a strong pungent odor, and it is highly volatile, forming a reddish-brown vapor. It looks like a red cloud, which is a significant feature of bromine.
Bromine is chemically active. In the series of halogen elements, its oxidizability is quite considerable, and it can be directly combined with many metals. If it encounters sodium metal, it quickly reacts violently to form sodium bromide. Bromine can also undergo substitution reactions or addition reactions with many organic compounds. For example, under certain conditions, bromine can undergo an addition reaction with ethylene, causing the reddish-brown of bromine to fade away. This is one of the common methods for identifying unsaturated hydrocarbons such as ethylene.

What are the physical properties of 1-bromo-2-chlorobenzene?
Mercury, or mercury, is the only metal that exists in a liquid state at room temperature and pressure, and its many physical properties are very unique.
Mercury has significant liquid properties. Under normal circumstances, it is a flowing and bright silver liquid, similar to smart silver water, which can be freely deformed and can converge into round and moist mercury beads in a flat place, just like a natural mercury ball. This fluidity and plasticity are one of its major characteristics.
Its density is quite high, reaching 13.59 grams/cubic centimeter, far exceeding the density of common liquids such as water. This property makes mercury heavier in liquids. If mercury is placed on top of other liquids, it will sink rapidly.
Mercury has an extremely low melting point, only -38.87 ° C, so it is a liquid at room temperature. However, once the temperature drops below the melting point, mercury will solidify into a solid state, resembling a silver metal block. Its boiling point is 356.6 ° C. When the temperature rises to the boiling point, mercury will rapidly vaporize and turn into mercury vapor. This gaseous mercury is colorless, odorless, but toxic.
Mercury also has good electrical conductivity. Like most metals, it can conduct current in circuits and has certain applications in electronic equipment and other fields.
Bromine is the only non-metallic element that is liquid at room temperature and pressure, and its physical properties are unique.
Bromine is usually a dark brown-red liquid with rich and unique colors and high visual recognition. Close to the smell, there is a strong and pungent smell, giving people a distinct feeling.
The density of bromine is greater than that of water, about 3.119 grams/cm3. If bromine is mixed with water, bromine will sink to the bottom.
Bromine is volatile and will continue to evaporate reddish-brown bromine vapor at room temperature. This vapor is corrosive and toxic and needs to be treated with caution. Even in relatively confined spaces, it can spread quickly.
Bromine is slightly soluble in water and has limited solubility in water, but it is soluble in a variety of organic solvents, such as carbon tetrachloride, carbon disulfide, etc. After dissolving, the color of the solution will vary depending on the solvent and concentration.

What are the uses of 1-bromo-2-chlorobenzene?
Mercury is one of the metals. It is liquid at room temperature, shimmering with silver light, and has special properties. Mercury has a wide range of uses and is reflected in many fields covered in "Tiangong Kaiwu".
First, in alchemy, mercury is very important. In ancient times, alchemists believed that alchemy could achieve longevity, and mercury was often the key raw material for alchemy. For example, the writings of alchemists such as Ge Hong often mentioned the use of mercury to participate in the refining of alchemy, hoping to use its characteristics to refine magical immortal medicines. Although this purpose is impractical in today's view, alchemy activities at that time greatly promoted the understanding of the nature of mercury.
Second, in the metallurgical industry, mercury is also useful. "Tiangong Kaiwu" records that mercury can be used for the extraction of precious metals such as gold and silver. Because mercury can form amalgam with gold and silver, with the characteristics of amalgam, it can effectively separate and enrich the gold and silver in the ore, and then heat and other treatments to volatilize the mercury, so as to obtain pure gold and silver. This is one of the important metallurgical methods in ancient times.
Third, in the field of medicine, mercury has certain medicinal value. Ancient doctors believed that mercury and its compounds have disinfection, sterilization, and antiseptic effects, and often used it in some formulas to treat scabies, sores and other diseases. However, at that time, there was a lack of understanding of mercury toxicity, and improper use of mercury would also lead to many adverse consequences.
Fourth, mercury is also used in daily life decoration and other aspects. For example, when making mirrors, mercury amalgam was applied to the back of the glass, which formed a reflective layer after treatment, making the mirror smooth and clean, adding convenience and interest to the lives of the ancients.
To sum up, mercury was used in many industries in ancient times. Although limited by the times, the application is unscientific, but it still plays a role in promoting the development of ancient science and technology and culture.

To make amalgam and iodine, the method is as follows:
To make amalgam, first take an appropriate amount of mercury and put it in a clean vessel. For mercury, a metal that is liquid at room temperature is also silver-shiny and has good fluidity. Then according to the characteristics and uses of the required amalgam, select suitable metals, such as zinc, tin, etc. Grind the selected metal into a fine powder and slowly add it to the container containing mercury. In this process, use a clean utensil, such as a glass rod, and gently stir to fully contact and fuse the mercury with the metal powder. Due to the special physical properties of mercury, it can dissolve a variety of metals to form amalgam. This fusion process may take some time, and care must be taken when stirring to prevent the mercury liquid from splashing out. Because it is toxic, accidental contact or inhalation of mercury vapor can endanger health.
As for the preparation method of iodine, first take an appropriate amount of iodine. Iodine is a purple-black crystal with sublimation properties. Place the iodine in a heat-resistant container, and then slowly add alcohol. Alcohol, commonly known as ethanol, is a common organic solvent. After adding alcohol, let it sit on a low fire or in a warm place, and gently shake the container to help the iodine dissolve in the alcohol. The solubility of iodine in alcohol is limited, so the amount of iodine added needs to be precisely controlled to obtain iodine with suitable concentration. During the dissolution process, it can be observed that the purple-black of iodine is gradually integrated into the alcohol, making the solution appear a unique brown-yellow color. When the iodine is completely dissolved, iodine is made. This iodine is often used for skin disinfection, etc., but when using it, pay attention to the appropriate amount to avoid excessive irritation to the skin.

What are the precautions for storing and transporting 1-bromo-2-chlorobenzene?
Mercury, arsenic and mercury need to be paid attention to in the storage and storage of many things.
Mercury is a liquid gold, which is toxic and toxic. If it is stored, it is the first heavy density. Use a special container, and the equipment is fixed, so that mercury does not react, such as thick-walled glass bottles or gold cans, the mouth of the bottle or can is sealed to prevent mercury from evaporating and escaping. The place where it is placed should be cool and transparent, and the source of ignition and pollution. Due to the increase in temperature, mercury will accelerate.
In addition, mercury is easy to form alloys with multiple gold, so it cannot be combined with this gold, such as gold, gold, etc., or the reaction of mercury, and the mercury-causing properties may also be changed. Mercury, including mercury, can be. It should not be well sealed, and anti-collision and shock-proof materials are still needed for the outer shell to prevent the container from breaking and mercury from escaping on the way. People should also work hard to cultivate, familiar with the hazards of mercury and the method of leakage.
Arsenic is also toxic. If it is stored in a dry environment, it should be stored in a dry environment. Due to moisture or arsenic-causing compounds, it absorbs moisture, and it is stored in acid and water. Arsenic compounds are multi-acid and anti-shock, which affects their qualitative safety. Arsenic should be properly packaged to indicate that it is toxic. Tools should be used to avoid mixing food, materials, etc. to prevent pollution.
Therefore, mercury and arsenic are toxic substances, and they should not be lost in terms of storage and storage, density, isolation, correct packaging, suitable environment and human labor. It is necessary to be careful to ensure safety.
