Otaku Engineer in Great Tang Dynasty Chapter 629: A genius is a genius~!

"Xiao Xuan, this "Chemistry", how much is true about what is said in it? How does the old man feel a little mysterious looking at it~?"

After the meal, the few people did not leave, but chatted with each other while drinking tea in the main hall. Wang Ji picked up a book on the table beside him, pointed to the book and asked Li Zexuan.

It is worth mentioning that Wang Ji drank so many immortals drunk at noon. At this moment, his cheeks were only red, and the whole person was not drunk. This amount of alcohol made Li Zexuan a little admired.

"This "Chemistry", the kid can guarantee that ten percent is true~! Chemistry, chemistry, is about the study of change, if you just read the book, you will indeed feel a little mysterious~!"

Li Zexuan said with a smile, he was very confident in the course of "Chemistry". He was a chemistry class representative in his previous life, and he ranked among the best in every exam. In this life, he has abnormal mental power. I am more confident that I will not go wrong.

Wang Ji nodded thoughtfully. After a while, he asked tentatively: "The size of this book is really rare in the world. Although the old man will have time to read through it in the future, it is only based on the first half of it. Speaking, doesn’t it mean that all the substances in this world can be transformed into each other~?"

Li Zexuan was slightly stunned. He didn't expect that Wang Ji, an "old naughty boy", would be interested in "Chemistry". He thought about it and replied:

"In terms of the mutual transformation of elements, Mr. Wang, your statement is indeed correct~! But sometimes we have to consider reality, because many chemical reactions have very strict requirements for external conditions , Such as temperature or catalyst, etc., if the specific conditions are not met, even if the two substances are put together, they will not undergo a chemical reaction, let alone complete the mutual transformation between the substances~!"

Wang Ji frowned and said in surprise: "This little chemistry, there are so many ways~?"

Li Zexuan smiled and said: "Of course~! The content of this course is strictly speaking, it covers everything in the world~! You know, there are millions of things in the world, and there will be more chemical reactions between each other~! So There is a lot of knowledge here~!"

Wang Ji listened while pinching his chin and thinking carefully. After a long while, he opened the book and pointed to one of the pages to ask:

"You use chemical symbols to express many substances based on the elemental composition. Of course, the old man doesn’t know whether you’re right or wrong, so just follow your thinking. For example, in this chapter, you say that hydrogen can be in oxygen. It burns to produce water. According to your previous meaning, doesn’t it mean that water can be converted into hydrogen and oxygen under certain special conditions~?"

Li Zexuan is really surprised at this time. Wang Ji's thinking and his ability to draw inferences from one another are really different from the capable people of this era~! Maybe this person can really............

Thinking of this, Li Zexuan explained earnestly: "Mr. is right. Water can indeed be decomposed into oxygen and hydrogen. If you look back, you can see it in the next chapter~! But now The kid can also tell her seriously~!

The so-called chemical change is the process of dividing molecules into atoms and recombining atoms into new molecules. If you read the previous chapters, you will have a general understanding of the concepts of molecules and atoms~! Both hydrogen and oxygen molecules are diatomic molecules, but a water molecule is composed of three atoms. In comparison, the chemical properties of hydrogen molecule are very active. It can burn in oxygen and generate heat while releasing heat. For water with relatively stable chemical properties, you can calculate the ratio of 2 to 1 to 2 based on the number of atoms among the three. During the reaction, the number of atoms is conserved.

Just now you asked how water turns into hydrogen and oxygen. This kid will also talk to you about it~! I said earlier that when hydrogen is burned in oxygen, it releases heat and produces chemically stable water. Now if we want chemically stable water to become chemically active hydrogen and oxygen, we have to pay. A certain amount of energy is needed to promote this chemical reaction to proceed normally~! What I want to tell you here is that energy is conserved at all times~! "

Wang Ji was startled, he seemed to have thought of something, and muttered: "Energy conservation, matter conservation, all things grow together~! This little chemistry actually implies the way of heaven~?"

During Wang Ji’s life, he had three official positions and three retreats. In order to obtain spiritual satisfaction, he was very knowledgeable about Taoist culture, and his thoughts and some of his later works were also deeply influenced by Taoist culture. At this moment After he listened to Li Zexuan’s explanation, he immediately remembered the Taoist thoughts about the coexistence of all things and the conservation of yin and yang. Wang Ji, who was originally interested in "Chemistry", felt the door to a new world at this moment. Opening up to himself, he wanted to understand this knowledge more and more.

"Then what kind of energy is needed to turn water into hydrogen and oxygen~? Does it need to be heated~? No, right? Normally, when we boil water, we don’t see the water turning into hydrogen and oxygen~ ?"

For a while, Wang Ji couldn't help asking.

Li Zexuan was about to explain, but Yan Silu interjected at this time: "Wang Wugong, you just saw less than an hour's begging, now you start to have ideas~? Don't you not know how to pretend to understand , Make a joke in front of the younger generation~!"

Li Zexuan and Wang Ji talked about chemistry, but he listened to Li Gang and Mo Huai with a little knowledge and depressed for a long time. After all, he couldn't help asking.

"Shit~!"

Wang Ji curled his lips~IndoMTL.com~ sneered and said: "You can't make a good face, but it doesn't mean that Wang Ji can't do it~! I have already said that Wang Ji is better than you and learns everything faster. You don’t believe it~!"

"Wang Wugong~! You have a big tone~! You just know some furs, how can you brag here~? Don't want to face~?"

How did Yan Silu endure such humiliation, so he furiously said.

Wang Ji retorted: "Fur~? It is indeed a fur, but it only takes less than an hour to understand the fur. Does this mean that the old man learns things faster than you~? Now, Do you dare to return Yan Kong and say that Wang Ji is not worth the monthly salary of five buckets of wine~?"

Yan Silu was dissatisfied and said: "Yanhuang Academy will be the elite school of my Datang in the future. How can you ask you, a gentleman who only understands fur, to mislead people~? Don't talk about five buckets of wine. A bucket of wine is too much for you~!"

"Hmph~! The old man only knows about fur now, doesn't mean he will be like this after school starts~! Yan Silu, you dare to gamble with Wang~?"
