Mercury is a metallic element. It is liquid at room temperature and has a silver-white color and metallic luster. Its chemical properties are relatively special. Although it has certain stability, it can react with a variety of substances.
Mercury can slowly evaporate at room temperature to form mercury vapor. This mercury vapor is toxic. If inhaled, it will damage the nervous system, kidneys and many other organs. Under heating conditions, mercury can react with oxygen to form mercury oxide. Its chemical reaction formula is:\ (2Hg + O_ {2}\ xlongequal {\ triangle} 2HgO\).
Mercury can also quickly combine with sulfur powder to form mercury sulfide, which is often used in the treatment of mercury leakage. Mercury sulfide is stable in nature, and its color is usually black or red. Its reaction is:\ (Hg + S = HgS\).
As for heavy water, it is a special form of water, and its chemical composition is\ (D_ {2} O\), in which the hydrogen atom is deuterium (heavy hydrogen). Heavy water is similar in appearance to ordinary water, colorless and odorless, but its physical and chemical properties are slightly different from ordinary water.
Heavy water has a slightly higher density than ordinary water, a boiling point of about\ (101.42 ^ {\ circ} C\), and a freezing point of about\ (3.82 ^ {\ circ} C\). Heavy water is relatively stable in chemical properties, similar to ordinary water, and can participate in many chemical reactions, but the reaction rate may be different from ordinary water. In nuclear reactors, heavy water is often used as a neutron reducer because it can slow down neutrons and facilitate nuclear reactions. In some organic synthesis reactions, heavy water can also act as a solvent, affecting the reaction process and product structure.

Saltpeter, its use is very wide. In the art of fire attack, it is especially important. Burning it explodes, the sound shakes the four fields, the power is amazing, and it can be a sharp weapon for breaking the city and pulling the fortress. In ancient battles, saltpeter was often mixed with medicine, made into firearms, killing the enemy far away, making the enemy terrified.
Sulfur is also multi-effective. In the method of alchemy, indispensable. Co-refining with other things can transform hardware, change its shape, and be valued by alchemists. And sulphur is hot, and can be used as medicine to treat all kinds of cold diseases, warm the meridians, and save people's lives.
Charcoal is a must for making fire. When cooking, use charcoal for burning, the fire is fierce and long, and it can help with diet. In the matter of metallurgy, charcoal is also an essential material, which is smelted in the blast, so that the ore can be dissolved into liquid to obtain fine iron and copper.
As for mirabilite, its uses are quite different. In the way of medicine, mirabilite can be released, and it can relieve the stagnation of the viscera. In the industry of tanning, it can make leather soft and easy to process.
Heavy water, although it does not exist in ancient times, but now I think about it, if it is placed in ancient times, it should also be of strange use. It can be used as a special water liquid for alchemy to help exert the power of medicine and make the medicine more powerful. In fire attack equipment, its performance may be improved to make its power even more powerful, adding strange help to the war.

If you want to make the medicine of nitrate fire, the ratio of saltpeter, sulfur, and charcoal is related to its properties and is the key.
Saltpeter, refine it with fire, remove its impurities, and then get a pure product. It is collected from the mountain soil and rocks, its color is white or slightly yellow, and its quality is brittle. Exposure under the scorching sun can remove its moisture to make its properties purer.
Sulfur, choose the yellow and bright one. First wash it with water, remove its filth, then melt it with charcoal fire, remove its residue, and after condensation, return it to a solid state before it can be used for backup. This sulfur is strong and is an essential agent for nitrate fire.
Charcoal, should be fired from solid wood, which is light and porous, preferably pine and cypress. When burning charcoal, the heat must be appropriate, and it should not be turned into ash, but only its charcoal. When the charcoal is formed, crush it with a pestle and form a powder.
For making nitrate fire medicine, the ratio of saltpeter, sulfur and charcoal is as follows: seven taels of saltpeter, one tael of sulfur, and two taels of charcoal are appropriate. Place these three in a stone mortar and gently pound with a pestle to mix them evenly. Do not use force at first, for fear that it will become impatient. After mashing well, wrap it in paper and seal it with wax to prevent moisture from invading.
The medicine of nitrate and fire thus obtained can be used in fireworks, firearms, etc. When used, care must be taken to prevent accidents. It is also for use, and it can be used as a sharp weapon in war, and it can be used as a firework in festivals, adding color and splendor, and its function is quite great. However, its nature is fierce, and it should be carefully prepared and used. Follow the ancient method and do not miss it a little.

There are saltpeter, realgar, mercury and other substances today, and their impact on the environment cannot be ignored.
Saltpeter, the chemical name is potassium nitrate. In ancient times, it was mostly used for alchemy and gunpowder. If dispersed in large quantities in the environment, its nitrate ions can cause eutrophication of water bodies. Aquatic plants grow wildly because of this, covering the water surface, causing underwater organisms to find it difficult to obtain light, oxygen is also gradually thinning, the water ecological balance is broken, fish and shrimp may die, water quality deteriorates, and the stench is unpleasant.
Realgar, a mineral of arsenic sulfide. Its color is orange-yellow and toxic. If released in the environment, arsenic can enter the body of organisms through water, soil and other media. If humans and animals eat water or materials containing arsenic, it can cause poisoning, sometimes vomiting, abdominal pain, and life-threatening when severe. And arsenic is difficult to degrade in the environment, accumulates for a long time, reduces soil fertility, hinders vegetation growth, and damages ecosystem diversity.
Mercury is a liquid metal, also known as mercury. Its volatility is strong, and mercury vapor is toxic. If mercury leaks into the environment, it evaporates into the atmosphere, diffuses with the airflow, and re-settles in the ground, into the soil and water. In water, mercury can be converted into methylmercury by microbial action, and its toxicity increases sharply. Fish are enriched in methylmercury. When humans eat it, mercury accumulates in the body, damaging the nervous system, immune system, etc., and causing developmental abnormalities in children. Soil contains mercury, plants do not grow well after absorption, and agricultural products also contain mercury, which endangers food safety.
These substances are harmful to the environment, so when using them, be careful to prevent them from escaping, so as to ensure the safety of the environment and the peace of life.

The genus of nitrate fire is widely used. For example, the number four of nitrate medicine is called methyl ether oil, and the number five is called heavy gas. These two are widely used in many fields.
Looking at the way of military industry, methyl ether oil and heavy gas are both important things. Methyl ether oil can help the power of firearms, making the hair of projectiles more fierce, and when attacking and breaking barriers, it shows its power. Heavy gas can adjust the properties of gunpowder, making the effect of explosion more accurate and powerful. It is very powerful above the battle formation, so in the field of military industry, these two are indispensable.
As for the chemical industry, methyl ether oil can be used as a raw material for many compounds. Due to its unique properties, it can combine with various substances to produce novel materials, which can be helpful in many aspects such as equipment manufacturing, fabric dyeing, etc. Heavy gas also plays a key role in the chemical process, catalyzing reactions, making the synthesis more smooth, and improving the quantity and quality of output. The prosperity of the chemical industry is due to the contribution of methyl ether oil and heavy gas.
Furthermore, in the process of scientific research, methyl ether oil and heavy gas also help. The characteristics of methyl ether oil can be used in experiments to explore the properties of substances and the principle of reactions, providing a way for the expansion of scientific understanding. Heavy gas is used in high-end experimental equipment to ensure the stability of the environment, assist in accurate measurement, promote the progress of scientific research, and the development of scientific research.
In summary, methyl ether oil and heavy gas are widely used in military, chemical, and scientific research fields, contributing a lot to the progress of the world.
