Mercury is a highly toxic substance with active properties. Compared with sodium amalgam, sodium amalgam has different properties due to the sodium element.
Mercury is a liquid metal at room temperature, with a metallic luster, volatile, and highly toxic vapor. Its chemical properties are relatively stable, and the common valence is + 1 and + 2. Mercury can form alloys with a variety of metals, called amalgams.
Sodium amalgam is an alloy of sodium and mercury, and its chemical properties are both sodium and mercury. Sodium is extremely reactive. It reacts violently with water to form sodium hydroxide and hydrogen, which is extremely violent and may even cause an explosion. In sodium amalgam, the reactivity of sodium is reduced due to the presence of mercury. When sodium amalgam reacts with water, the reaction rate is much slower than that of pure sodium and water, and sodium hydroxide and hydrogen are formed, but chemical reactions still occur.
Mercury can react rapidly with sulfur powder to form mercury sulfide. This reaction is often used to treat spilled mercury. Due to the stable nature of mercury sulfide, its toxicity is much lower than that of mercury. Sodium in sodium amalgam can also react with acids to form corresponding salts and hydrogen gas.
In addition, mercury can react with oxidizing acids such as nitric acid to form different products depending on the concentration of nitric acid. Sodium in sodium amalgam can be used as a reducing agent in some chemical reactions to provide electrons for the reaction. However, it is necessary to keep in mind that mercury and its related substances are highly toxic, and strict safety regulations must be followed when using and handling them to prevent serious harm to humans and the environment.

Mercury is a highly toxic substance and is also a liquid metal. It flows in a silvery state at room temperature. It has many special physical properties. When it is combined with tin and placed in lead and mercury, its properties are quite wonderful.
Mercury has a very low melting point, about -38.87 ° C, so it is liquid at room temperature and easy to flow, just like smart silver water. Its boiling point is also not high, about 356.6 ° C. It is easily volatile when heated and can slowly turn into mercury vapor in the air. This mercury vapor is highly toxic. If inhaled inadvertently, it will seriously damage human health and damage the nervous system, kidneys and other important organs.
Mercury has a very high density, up to 13.59g/cm ³, which is abnormal in weight compared to many common metals. When it is combined with tin for lead amalgam, mercury can form an alloy with metals such as tin. Lead amalgam has unique properties, and its hardness and melting point have changed compared to pure metals. This alloy has been used in some processes in the past, such as the ancient gilding process, which used lead amalgam.
The surface tension of mercury is quite high. On a smooth surface, the mercury droplets will shrink into a nearly perfect spherical shape, like round silver beads. This is because the surface tension prompts the mercury droplets to tend to the smallest surface area. In addition, mercury is a good conductor. Although its electrical conductivity is not as excellent as that of copper and silver, it can also conduct current well, and may be used in some specific electrical devices.
However, due to the severe toxicity of mercury, it is used with extreme caution today. Although ancient people knew and used some of its properties, there may be deficiencies in protection. Today, we should pay more attention to the hazards of mercury and properly use and dispose of mercury-containing substances to protect the natural environment and human health.

Between the Fuhe River and Huai River, there are two common methods for making acetylene. One is the calcium carbide method, and the other is the natural gas cracking method.
The calcium carbide method uses calcium carbide (calcium carbide) to react with water to produce acetylene. When calcium carbide enters water, its reaction is fast and intense, like a dragon stirring the sea, making a loud noise. Although "Tiangong Kaiwu" does not elaborate on this modern method, its principle is connected with the ancient chemical changes. When calcium carbide encounters water, calcium in calcium carbide and the hydroxide of water combine to form calcium hydroxide, and carbon is combined into acetylene gas to escape. This method of acetylene is simple in equipment and easy to operate. It was widely used in the early days of industry in the past. However, the preparation of calcium carbide can consume a lot of energy, and the cost is high, and there are also many inconveniences.
The natural gas cracking method uses natural gas as the source and produces acetylene through high temperature cracking. Natural gas is baked at high temperature in a special furnace, like a phoenix on fire, and the molecular structure is rearranged. At high temperature, methane breaks the carbon-hydrogen bond, and the carbon atoms polymerize into acetylene, and the hydrogen atoms form hydrogen. This method of acetylene has abundant raw gas reserves, lower cost than the calcium carbide method, and the product is pure. However, it requires high temperature conditions, extremely high equipment requirements, and high technical thresholds.
Ancient chemistry, although not as fine as today, has changed the principle. Calcium carbide method and natural gas cracking method have their own advantages and disadvantages, depending on the needs of the time, the amount of materials, and the level of technology.

In "Tiangong Kaiwu", there is a saying: "Where gunpowder is pure yang, sulfur is pure yin, and nitrate is pure yin, this universe is like a divine object." Sulfur and saltpeter are combined as medicine, which has wonderful uses in many fields.
In the military field, gunpowder, which is a combination of the two, is a weapon of war. Ancient firearms, such as piercing guns, artillery, etc., all rely on this to make their power. Take artillery as an example, the gunpowder is loaded into it, and after igniting, the gunpowder instantly explodes, generating a strong thrust, so that the artillery shells can be shot out like thunder. On the battlefield, it can destroy the sharpness and cause chaos in the enemy formation. It plays a crucial role in attacking cities and defending against the enemy.
In the field of folk fireworks, gunpowder also shines brightly. During festive celebrations, fireworks bloom in the night sky, which is beautiful. Based on black powder, adding different metal salts can present colorful colors. This is all due to the energy generated by the reaction of sulfur and saltpeter, which promotes fireworks to rise and bloom, bringing joy and a festive atmosphere to the people.
In addition, it can also be seen in some traditional handicrafts. For example, some traditional alchemy techniques, although there are many absurdities, in the process of exploration, there are many studies on the characteristics and compatibility of sulfur and saltpeter. Some folk incense-making processes also skillfully use the characteristics of the two to make the incense not only fragrant, but also unique in the burning process, or uniform burning speed, or long aroma.
Sulfur and saltpeter are combined as medicines. In the fields of military, fireworks and traditional techniques, with its unique nature, it plays an irreplaceable function. It is the crystallization of ancient wisdom and has far-reaching influence in many aspects.

In the land of Jiangyou, sugar and cane are planted together. And the sugar industry has been prosperous for a long time.
Looking at its market prospects today, it can be said to be quite impressive. Jiangyou has fertile soil and warm climate, which is very suitable for sugarcane species. Sugarcane is lush, and the source of sugar is abundant. The people of the area are mostly skilled in sugar making, and they have been passed down from generation to generation, and their skills have become more and more exquisite. The sugar made is pure in color and sweet in taste. It is famous from far and near, and merchants from all over the world come to buy it. This is the cornerstone of the market.
The road of free trade is getting wider, and the use of sugar is not limited to diet. In medicine, it can be used as a blending agent; in tea, it can increase the beauty of flavor. In addition to folk festivals, sugar is also a must-have, used to express sweetness and auspiciousness, and the demand is evident.
Looking at the surrounding places, either due to the unsuitable climate or the lack of refined skills, the output and quality of granulated sugar are not as good as Jiangyou. It is Jiangyou granulated sugar, which is quite competitive in the four-sided market. Even if there is competition for sugar from other places, Jiangyou's sugar, with its high quality, can still occupy a place.
As for overseas trade, there is also room for it. Nanyang states like to use granulated sugar. If Jiangyou can do a good job in management, expand sea trade, and make granulated sugar sold to foreign countries, the benefits will be great. And with the convenience of shipping, trade costs may gradually decrease, and profits will be more considerable.
To sum up, Jiangyou sugar and cane co-planting industry, the market prospect is broad, if we can take advantage of the situation, make good use of the right time and the right place, we will be able to make a fortune in the sugar industry, the interests of one side.
