3-pyridinecarboxaldehyde, 2-chloro-5-fluoro-

Those who are 3 +, those who are 2 +, those who are 2 +, those who are 5 +, and those who are boron. These are all chemical things, each with its own characteristics.
The first word is, the one who is the most important among the elements, the color is stinky. Its sexual activity is often able to combine multiple elements. Under normal conditions, it exists in the form of atomic molecule H ². In case of oxygen, if there is a fire source that burns, it can burn fiercely to generate water, and the inverse formula is 2H ² + O ³ = 2H ³ O, which can be used as a clean and efficient energy source.
Re-boron, boron is a solid and non-gold element, and its properties are crystalline or amorphous. Crystalline boron has a very high hardness and good performance. The chemical properties of boron are also very active, and it can combine elements such as oxygen and nitrogen. Boron and its compounds are widely used in many fields such as engineering, engineering, and engineering. For example, boric acid is often used for disinfection and corrosion prevention, and borax is used as a melting aid in glass, ceramics, etc.
It is not included in the list of common chemicals. If this is uncommon, we need more information to describe its properties.
Therefore, boron is an important element in the world, each because of its special chemical properties, and plays an important role in different fields, promoting the improvement of life through technological progress.

3 + The main use of it is 2-5-5-1.
In the case of "Heavenly Works", such things are of great use. 3 + Those who are of great use to it may be used in the way of stone. In ancient times, it was often used to explore the properties of things, so as to use them. The quality of a product, or it has a special effect, can cure all kinds of diseases.

The material, or resistant to water immersion, can protect the boat for a long time sailing, worry about floods.
Well, 3 + to its armor, 2 - 5 -, are all in many aspects of the ancient people's life, such as pollution, dyeing, construction, boats and other fields, which played an important role in the convenience of the ancient people's life and the development of culture.

If you want to make the potion of three yang, you need to follow the ancient method. First take good materials to conform to its nature, and then combine them with the principle of yin and yang to adjust them in an orderly manner.
The potion of two qi is made to avoid its cold and dryness. When you choose the right time, when the yin and yang are combined, take the essence of heaven and earth and combine them in one place.
As for the system of five qi, it is related to water and soil, those who are water and soil, and the foundation of all things. Take clean water and fertile soil, and use the method of combining water and fire to make them blend. First, use the heat to slowly bake, wait for the qi to be reconciled, and then use the fire to attack urgently to make it strong.
To make these potions, you need to understand the change of yin and yang, and know the principle of the Yin and Yang are also the way of heaven and earth, the discipline of all things, the parents of change, the beginning of life and death. The five elements, metal, wood, water, fire, and earth, are mutually reinforcing, and the cycle is endless. Only by using the principles of Yin and Yang and the five elements, adjusting the properties of all medicines, and combining the spiritual energy of heaven and earth, can you make good medicines.
When making medicines, your heart must be sincere and your will must be dedicated, just like you are to the gods. Every move follows the ancient teachings, and you dare not slack off at all. In this way, you can make a superior medicine to cure the diseases of the people and help the people.

If you use the ancient classical Chinese style of "Tiangong Kaiwu" to answer, it is roughly as follows:
The husband works with utensils, and he should pay attention to everything in the genus of mercury and lead, as well as in storage and transportation.
Mercury is strong and poisonous, and its qi can hurt people. If you hide it, you must use a secret utensil. Don't let it be released outside, causing the poisonous gas to disperse and harming everyone. The place where mercury is stored should be dry and cool, and avoid fire and heat to prevent its vapor from evaporating more and more. When transporting mercury, the person holding the utensil should be cautious and wrap it in a thick object to prevent it from pouring. If there is mercury leakage, quickly cover it with sulfur to reduce its poison.
Lead is heavy in quality and stable in nature. Where lead is hidden, it should be moisture-proof. If it is wet, it is easy to rust and damage its quality. When transporting lead, and when traveling on board a boat, it must be firmly bound to prevent it from falling. And although lead is not as toxic as mercury, it will not touch the skin for a long time, and there may be minor harm.
As for storage devices, whether it is mercury or lead, it must be strong and dense. Wood is perishable, so it is not suitable; although porcelain is dense, it is brittle and fragile, and it is not the best choice. Metal tools, iron or copper, are better, but iron is easy to rust, and copper is expensive. Each has its advantages and disadvantages, and it should be selected according to the situation.
The way of transportation is different from land and water. When traveling on water, the boat should be stable to avoid the rushing current and prevent the wind and waves from capsizing the boat. When traveling on land, the rut should be flat, and the bumps should not be too high. And the escort must know the nature of its things, and the place where it can be changed will be safe.
All these things are related to the storage and transportation of mercury and lead. Workers must not ignore it, and they must proceed with caution.

There is a question now, what is the impact of the three additions to the first, two, and five waters on the health of the human body in this environment? Let me say.
The husband is one of the things in heaven and earth. If the three additions are used, or their life is in balance. In nature, each has its own place, and each has its own responsibility. Too much, or it may lead to insufficient food sources, mutual destruction, or because of its prosperity, it invades the survival of other things, breaking the stability of living things.
When it comes to human beings, it is necessary for two things. It is necessary for human beings, and it is necessary for multiple physiological activities. It is also necessary for human beings to maintain a balance of liquids, gods, etc. Less often, the fluid is out of balance, the belief system is blocked, people may feel weak and tired, and even the normal work of the heart and muscles is affected.
And water is the source of life. In five cases, it is a big harm. Most of the people are water, and the new generation of water, the new generation of things and things. Less water, the generation of water, the whole body, the gathering of things. The mouth is dry, the skin is dry, and the function of the internal organs is affected, endangering life.
In the context of the situation, the amount of armor is low, and the influence of the biological system is determined. The change of water also affects soil, water, etc. Less or cause soil fertility to change, affecting plant growth. Water makes water dry up, aquatic life is broken, and aquatic life is broken.
Of course, these three factors do not affect personal health, or the environment. There are many unfavorable effects, so you can't be careless.
