"Xiao Xuan, how much of what is said in this "Chemistry" is true~? How does the old man feel a little mysterious when he looks at it~? ”

After the meal, several people did not disperse, but chatted while drinking tea in the main hall. Wang Ji picked up a book on the table next to him, pointed to the book and looked at Li Zexuan and asked.

It is worth mentioning that Wang Ji drank so much immortal drunk at noon, but his cheeks were red at the moment, and the whole person was not drunk, which made Li Zexuan a little admired.

"This "Chemistry", the kid dares to guarantee that it is ten out of ten true~! Chemistry is about the science of change, if you just look at the book, you will indeed feel a little mysterious~! ”

Li Zexuan said with a smile when he heard this, he is still very confident in the course of "Chemistry", he was also a representative of the chemistry class in his previous life, and he was among the best in every exam, and he has perverted spiritual power in this life, so he is more confident that he will not make mistakes.

Wang Ji nodded thoughtfully, and after a while, he asked tentatively: "The pattern of this book is so big, it is really rare in the world, although the old man will not have time to read it in the future, but just according to the first half of it, 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 Wang Ji, an "old naughty boy", to be interested in "Chemistry", he thought about it and replied:

"If it is based on the mutual transformation between elements, Mr. Wang, your statement is indeed correct~! However, sometimes we have to consider reality, because many chemical reactions have very strict requirements for external conditions, such as temperature or catalyst, etc., if they cannot meet specific conditions, even if they put two substances together, they will not have a chemical reaction, and they will not complete the mutual conversion between substances~! ”

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

Li Zexuan smiled: "Of course~!" The content of this course is strictly inclusive of all things in the world~! You must know that there are thousands of substances in the world, and there will be more chemical reactions between each other~! So there's a lot of knowledge in this~! ”

Wang Ji pinched his chin and thought seriously while listening, and after a while, he opened the book, pointed to one of the pages and asked:

"You represent many substances with chemical symbols according to the composition of the elements, of course the old man doesn't know whether you are right or wrong in saying this, just follow your thinking first, for example, in this chapter, you say that hydrogen can be burned in oxygen to produce water, then according to your previous meaning, doesn't it mean that water can also be converted into hydrogen and oxygen under certain special conditions~?"

Li Zexuan was really surprised now, Wang Ji's thinking, his ability to draw inferences from one another, is really different from the capable people of this era~! Maybe this guy can really ............

Thinking of this, Li Zexuan explained seriously: "Mr. is right, water can indeed be decomposed into oxygen and hydrogen, this point, if Mr. looks back, you can see it in the later chapters~!" But now the kid can also give Mr. a serious lecture~!

The so-called chemical change is the process of dividing molecules into atoms and recombining atoms into new molecules. Hydrogen molecules and oxygen molecules are diatomic molecules, but a water molecule is composed of three atoms, in contrast, the chemical properties of hydrogen molecules are very active, it can be burned in oxygen, while releasing heat, to generate chemically stable water, you can calculate their ratio according to the number of atoms between the three is 2 to 1 to 2, in the process of reaction, the number of atoms is conserved.

Just now you asked how water turns into hydrogen and oxygen, and this kid will tell you about it by the way~! As I said earlier, when hydrogen is burned in oxygen, it releases heat to produce chemically stable water, and now if we want to make chemically stable water become chemically active hydrogen and oxygen, we also have to pay a certain amount of energy to promote this chemical reaction to be able to proceed normally~! What I want to tell you here is that energy is conserved at all times~! ”

Wang Ji was stunned, he seemed to think of something, and muttered: "Conservation of energy, conservation of matter, all things are born together~!" This little chemistry actually implies the way of heaven~? ”

In Wang Ji's life, three Shi Sanyin, in order to get spiritual satisfaction, he is very good at Taoist culture, and his thoughts, some of his later works, are also deeply influenced by Taoist culture, at this moment, after listening to Li Zexuan's explanation, he immediately remembered the Taoist thought of all things in the symbiosis, Yin and Yang conservation theory, originally very interested in "Chemistry" Wang Ji, at this moment is feeling a new world door, open to himself, he wants to understand this knowledge more and more.

"So what kind of energy is needed to turn water into hydrogen and oxygen~? Don't you need to heat it up~? No, no, when we usually boil water, we don't see the water turn into hydrogen and oxygen~? ”

Secretly sighed for a while, Wang Ji couldn't help but ask.

Li Zexuan was about to explain, but Yan Silu interjected at this time: "Wang Wugong, you just saw the request for less than an hour, and you started to have ideas at this time~?" Don't pretend to understand and make jokes in front of the juniors~! ”

Li Zexuan chatted with Wang Ji about chemistry, but he and Li Gang and Mo Huai were in a fog and half-understood, and they were depressed for a long time, but he couldn't help but ask after all.

"Huh~!"

Wang Ji pursed his lips and sneered: "You can't return to Yan Kong, but it doesn't mean that I, Wang Ji, can't either~!" I said it a long time ago, my Wang Ji is better than you, and I can learn everything quickly, but you don't believe it~! ”

"Wang Wugong~! What a big breath~! You just know a little bit about it, how can you brag about it here~? Don't want a face~? ”

How could Yan Silu endure such humiliation, so he said angrily.

Wang Ji retorted: "Fur~? It's really fur, but it only took less than an hour, and I can understand fur a little, does this mean that the old man learns things faster than you~? Now, do you dare to say that my Wang Ji is not worth the salary of five buckets of wine per month~? ”

Yan Silu was unconvinced and said: "Yanhuang Academy will be the elite school of my Tang Dynasty in the future, how can I ask you, a gentleman who only understands fur, to mislead people's children~?" Don't talk about five buckets of wine, in my opinion, even if it's a bucket of wine, it's a lot for you~! ”

"Hmph~! The old man only knows fur now, but it doesn't mean that he will be like this after the start of school~! Yan Silu, do you dare to make a bet with Wang~? ”
