What is the balancing method for the reaction equation of ethene and the aromatic ring?The chemical equation for the reaction of ethene and benz to produce methylethlene was C6H6 + CH2 = CH2 → C6H5-CH2-CH3.
The least common multiple method could be used to balance the reaction equation:
1. First, find the element with the largest number of atoms on the left and right ends of the reaction formula. You can choose carbon or hydrogen atoms here.
- Taking carbon atoms as an example, before the reaction, there were 6 carbon atoms in the aromatic ring, 2 carbon atoms in the ethene, and a total of 8 carbon atoms. After the reaction, there were also 8 carbon atoms in the graphene.
- For the hydrogen atom, there were 6 hydrogen atoms in the aromatic ring before the reaction, 4 hydrogen atoms in the ethene, and a total of 10 hydrogen atoms. After the reaction, there were 10 hydrogen atoms in the graphene.
2. Because the number of carbon and hydrogen atoms before and after the reaction was equal, the equation had been balanced.
If the odd-number mating method is used (this reaction is not very typical, but it can be analyzed according to the principle):
1. Observing the number of atoms on both sides of the equation, it was not easy to find the typical odd-numbered spouse in this reaction.
- This was because the total number of carbon and hydrogen atoms on both sides of the reaction formula was an even number.
- From the perspective of chemical bonds, the combination of the double bond break of ethene and the bond break on the aromatic ring was consistent with the conservation of atoms before and after the reaction from the perspective of atomic number. There was no need for complicated odd-even balancing adjustments.

The most accurate method of choosing a dateQimen Dun Jia needed to consider many factors when choosing a date. First of all, a complete Dun Jia Plate contained six parts: Tian Pan, Di Tu, Eight Gates, Nine Stars, Eight Gods, and the color of the palace. They had to be arranged on the Nine Palaces according to specific rules. Then, according to their combination, they could judge good or bad luck, choose an auspicious time, and identify an auspicious place.
The eight gates of Qimen Dunjia also had a significance in choosing a date. For example, the Life Gate represented wealth. If you wanted to help in terms of wealth, you could consider the time selection related to the Life Gate. Opening the door represented career opportunities. If you were concerned about career-related matters, you could refer to the situation related to opening the door.
At the same time, to use Qimen Dunjia to choose a date, one must understand the principles of the Book of Changes and the five elements of Yin and Yang, be familiar with the interaction between the trunk and the branch, and have the knowledge of choosing a date. Because there were many Qimen Dun Jia schools, and each person had a different teacher, the method of setting the game was also different. This also caused the method of choosing a date to have different precise considerations between different schools and users. The Qimen Dunjia books passed down from ancient times had hidden meanings, contradictions, and errors. If it was not for the fact that they were taught by mouth and heart, it would be difficult to accurately grasp the method of choosing a date. Moreover, the basic structure of Qimen Dunjia reflected the personnel, life, social system, astronomy, geography, and other aspects of the society at that time. When choosing a date, these factors needed to be considered comprehensively.

Choose a single damage weapon such as a one-handed sword, a two-handed sword, a bow and arrow, and so on. Secondly, he had to learn to grasp the opportunity. He had to pay attention to the enemy's attack trajectory and defense route in battle, and launch precise attacks from their weaknesses. You also have to learn the correct attack techniques and use the correct attack methods, such as attack charging skills, to make your attacks more powerful and accurate. Finally, he had to learn combination skills, combining different skills and attack methods to achieve more efficient and accurate damage.
Which is more accurate, the six lines or the Dayan divination method?The six lines and the Dayan Divination Method were both traditional divination methods, but their accuracy had no scientific basis to compare.
The Dayan Divination Method was the only divination method recorded in the original text of the Book of Changes. It used yarrow as a medium to determine the lines and hexagrams related to the divination by calculating the number of yarrow. Its essence was the deduction of numbers. The process was relatively complicated and involved many concepts such as the number of heaven and earth.
The six lines used three identical copper coins or coins. After concentrating, shaking, throwing, and other operations, the Yin or Yang lines were determined according to the different results of the copper coins. A total of six shakes would result in the original hexagram. If there were old Yang or old Yin, it could also produce a change hexagram.
They were all divination methods based on the philosophical system of the Book of Changes. The results were interpreted in the traditional cultural and philosophical context rather than measured by the accuracy standards of modern science.
The most accurate method of free fortune-telling on the lunar calendarLunar fortune-telling mainly relied on the lunar month, day, and time of birth to calculate fate. One of them was zodiac matchmaking. It was based on the twelve zodiac signs of the lunar calendar. The year of birth was divided into different zodiac signs. Each zodiac sign had a unique personality and destiny, which could be used as a reference for choosing a marriage partner. There was also fortune-telling. According to the year, day, and time of birth in the lunar calendar, one could calculate the wealth, fortune, and misfortune of one's life. One could calculate the rough outline of one's fate, but it could not be detailed to a certain day or moment. However, it needed to be clear that the so-called lunar fortune-telling had no scientific basis to prove its accuracy.
