Mercury is a liquid with a silvery white color and metallic luster. It can evaporate into mercury vapor at room temperature. Its density is quite high, even more so than that of common things.
Water is colorless and transparent. It is a liquid at room temperature and pressure, tasteless and odorless. Water has good solubility and can dissolve many substances in it. Its boiling point is 100 degrees, and its freezing point is zero. The density of water is one gram per cubic centimeter. This property is of vital significance to the balance of all things in the world and the survival of life.
Bromine is the only non-metallic element that is liquid at room temperature and pressure. It is dark red-brown in color and has a strong irritating odor. Its volatility is strong, and its toxicity cannot be ignored. Bromine is denser than water, soluble in water, brominated water, and easily soluble in organic solvents.
Mercury, water, and bromine each have unique physical properties. Mercury is known to the world for its metallic liquid, volatile and high density; water is colorless, odorless, transparent, good solubility, specific melting boiling point and density; bromine is a dark reddish-brown liquid, highly volatile and toxic, and special solubility. The three are in nature, each in its place, in the composition and change of matter, and in the derivation and development of life. They all have unique functions. They are indispensable substances in heaven and earth, and are also key objects for the world to explore nature and study physical chemistry.

Mercury, rivers, and sea mussels are all natural things, and their chemical properties are different. Today, let's come to you one by one.
Mercury, commonly known as mercury, is the only metal that exists in liquid form at room temperature and pressure. Its color is silver-white, heavy and flowing. Mercury's chemical properties are relatively stable, and it is not easy to react with oxygen. However, when heated, it can oxidize and form mercury oxide. Mercury can dissolve many metals and form amalgams. This property is widely used in metallurgy and other fields. However, it should be noted that mercury and its compounds are toxic. If inadvertently ingested or inhaled mercury vapor, it will cause serious damage to human health, harming nerves, kidneys and other organs.
River, where water flows. In river water, in addition to water, there are many minerals and trace elements, such as calcium, magnesium, potassium, sodium and plasma, whose chemical properties depend on the substances contained. River water is weakly acidic or weakly alkaline, which varies from region to region. River water can participate in many chemical reactions, such as reacting with carbon dioxide to form carbonic acid, which in turn affects the pH of the water body and the balance of material dissolution. In addition, microorganisms in river water also participate in various biochemical reactions, which have a profound impact on water quality and ecological environment.
Sea mussels are shellfish organisms born in the sea. The main component of its shell is calcium carbonate, which has a certain chemical stability. Calcium carbonate reacts with acid to produce carbon dioxide gas. The body of sea mussels also contains a variety of biomolecules, such as proteins, nucleic acids, etc. These biomolecules play a key role in the life activities of sea mussels and participate in many physiological processes such as metabolism and immune defense. During the growth process, sea mussels ingest calcium, magnesium and other elements from seawater to build their own shells and maintain physiological functions.

Mercury, river, and sea clam have different uses.
Mercury, also known as mercury, is a liquid metal. Its uses are quite extensive. In ancient times, it was often used in alchemy. Although the alchemists wanted to use mercury and other substances to refine elixirs of immortality, although they were ultimately unsuccessful, the alchemy process also promoted the development of ancient chemistry. In the field of medicine, mercury compounds were used in pharmaceuticals, such as in some ointments for treating skin diseases or containing mercury. However, due to the toxicity of mercury, it is now used with extreme caution. In industry, mercury can be used to make thermometers, which can accurately measure temperature due to their stable thermal expansion and contraction properties. It is also used to make mercury lamps, which emit special spectra, and is used in lighting and other fields.
The river is formed by the convergence of water flows and has many functions. First, it is the source of irrigation, nourishing the farmland on both sides, enabling the growth of crops and ensuring the supply of food for the people. Second, it is the main road for water transportation, which can be used by boats and boats to promote the circulation and trade of materials in various places. Whether it is freight transportation or personnel travel, the river provides great convenience. Third, it is the habitat of many organisms, which breeds rich aquatic organisms and maintains ecological balance.
The sea clam is a shellfish creature. Its meat is edible, delicious and nutritious, and it is a delicacy on the table. Its shell can be used for decoration, polished to shine, and made into various ornaments; it can also be used as raw materials for handicrafts, which can be carved into exquisite objects by craftsmen. In addition, some sea mussels can breed pearls, which are round and shiny, making them valuable jewelry and valuable in the jewelry industry.

The synthesis of mercury, river, and sea mussels has existed in ancient times, and it is also described in Tiangong Kaiwu and other ancient books.
The synthesis of mercury in ancient times mostly used the method of burning Dan sand. For Dan sand, mercury sulfide is also. Take Dan sand and put it in a closed vessel, calcine it with fire, Dan sand is decomposed by heat, and sulfur and mercury are separated. Mercury is a liquid metal, volatile, and can be collected by condensation. As recorded in the book, "Where cinnabar, mercury, and silver vermilion are originally the same thing, so those with different names are divided into coarse, old, and tender. Where a liter of mercury is used, either with white secondary sand, or with a tank that falls out of the floating surface of two vermilion, the water and the chaff form a large plate, and every 30 catties is put into a kettle to raise mercury, and the carbon under it is also used for 30 catties. "This is the method of refining mercury from Dan sand, by means of heat and utensils, to change Dan sand and obtain pure mercury.
The formation of rivers originates from natural creation. The snow on the mountains melts when it is warm, and trickles, converge to form a stream, and the stream merges to form a river, and the river merges to form a river. The so-called" those in the river abyss are also the dwellings of dragonfish. Those in the mountains and forests are also the dwellings of birds and beasts. "The river flows endlessly, and the water supply continues There is also rain that falls on the ground, seeps into the ground, and gushes out again into springs, which gather together, and are also the water source of rivers. In its process, it wraps sediment, minerals, etc., shaping the terrain and moisturizing all things.
The breeding of sea mussels, in the shallow sea, where the water temperature is suitable and the bait is abundant, is the place where they multiply. Sea mussel larvae, drifting with the current, meet the appropriate substrate, that is, attached to growth. It feeds on plankton in the water, and over time, the shells become larger and the body becomes stronger. Ancient fishermen, or knowing their habits, set up reefs and rocks in suitable places to attract sea mussels to attach, and wait for them to grow and harvest. "There are mussels in the sea, which are pregnant with beads and produce wonderful colors. Its life is also dependent on the shallows and reefs, absorbing the essence of the sea, nurturing beads and resplendent. "The growth of mussels is related to many factors such as water quality, temperature, food, etc. Only when the environment is suitable can they breed good products.

Mercury, rivers, and sea clams should be stored and transported with a lot of attention.
Mercury, which is highly toxic, must be stored in a closed container to prevent volatilization. The container should be sturdy, free from leakage, and placed in a cool and ventilated place, away from fire and heat sources, to avoid its heat and accelerate volatilization, causing toxic gas to overflow. When handling, also handle it with care to avoid damage to the container and mercury overflow. If mercury spills, cover it with sulfur powder immediately to make it synthesize into mercury sulfide, reduce its toxicity, and collect and clean it properly, so as not to pollute the environment.
The water transportation of rivers is related to many things. Water source protection is essential to prevent sewage from entering the river and causing water quality deterioration. During transportation, pay attention to the water level and current. In case of floods, droughts, etc., the transportation plan should be adjusted in a timely manner. And the ship's navigation should be in compliance. Do not cause the goods to fall into the water due to improper operation and pollute the water body.
Sea clams are stored and need to be kept fresh. Temperature and humidity should be controlled, usually in a low temperature and humid environment. Sea clams can be placed in a special container with a damp cloth or an ice pack to cool down. During transportation, a stable environment should also be maintained to avoid injuries caused by bumps and violent vibrations. At the same time, pay attention to the transportation time, and do not keep them for a long time to avoid sea clams dying due to hypoxia and lack of water.
All these matters need to be treated with caution. When storing and transporting mercury, river transportation, and sea clams, one must not be negligent to avoid disaster or loss.
