Lan Jie bought a latte + croissant breakfast for 6 yuan at KFC at the gate of Sheep, and the latte cup was printed with the signature of FPX.Crisp.

Lan Jie decided to give more dignity to the two auxiliary bodyguards, chemistry and biology, especially chemistry, which is very closely related to physics, and physics and chemistry are often bound together to lead a path.

It is impossible to change the status of chemistry as a tool, but tools are also divided into intelligent tools and primitive tools.

'Chemical, I, Applejack, have the mercy to promote you as a smart tool, please don't let me down. ’

Lan Jie came to the second and third class classrooms, and he greeted Li Zihan warmly: "Li Zihan, morning! You come to the classroom so early every day, you are so diligent, and today is also diligent, which is admirable." ”

"Hmph, don't lick me, I'm not familiar with you!" Li Zihan sat in a row in front of Lan Jie, he didn't raise his head to read the math elective textbook, and didn't look at Lan Jie.

"Brother, a person who is sixteen or seventeen years old and almost twenty years old, will join the party in two years, can you be a little more mature?" Lan Jie took the throne, drank latte, and ate a song.

Li Zihan couldn't help but turn around and ask: "Lan Jie, you eat these junk foods every day, why can you grow to more than one meter and eight?"

Lan Jie shared his experience: "It doesn't matter what you eat, it's all about exercising, and sports promote growth. Li Zihan, you exercise a lot, you don't even have 10 hours of exercise a week, right?"

"Lan Jie, you encourage me to exercise all day long, but you are secretly studying, hehe, you are too scheming, you are very worried that I will surpass you in learning. ”

"Surpass me? Then you are super, I wish someone in the class would surpass me, hehehe. ”

Li Zihan's naïve remarks reflect an immature mind, and Lan Jie can be happy early in the morning.

The first class was at eight o'clock, and it was now half past seven, and Ranger kept his promise to give chemistry more dignity.

In an aqueous solution, the stable oxidation state of F is -1.

The main oxidation states of Cl, Br and I are -1, +1, +3, +5 and +7, and the oxygen-containing acids of halogens are all strong oxidizing agents, except for the -1 and +7 oxidation states, the other oxidation states are prone to disproportionation.

Hey?

It's weird.

Why do you just take out the F in this part of the chemistry elective about halogens?

Was this an oversight on the part of the teacher in writing the typesetting, or was there some hidden secret?

Ranger fell into deep thought, and he realized that F was not simple.

'Chemistry, you're getting more and more annoying, you're just a tool, why are there so many human thoughts?'

Langer turned to the next page, and the explanation on the chemical elective is that because F- has the smallest radius and the largest electronegativity, F- as a ligand, can stabilize the central element of the high oxidation state and achieve high coordination numbers, such as SbF5, UF6, IF7, RuF8, etc.

'Eh, fluorine compounds are very abstract, I haven't played with any of them, and I don't know what they look like, are they fragrant or smelly, colored?'

Since there is no physical object, Ranger can only do paper articles, and he tries to disassemble the pairs of electrons, but this thing is not easy to disassemble.

Ranger was sweating profusely, and his sketchbook was full of electrons excited by the p orbital.

Damn, I can't do it!

Lan Jie was frustrated, and after the defeat, he became more and more courageous, and he would not give up until he killed the little bastard of chemistry.

"That...... Rangier, are you free?"

"Not available. ”

"Is it okay to lend me a physics homework book?"

"Take it, walk slowly, don't send it. ”

"What a rude attitude, do you want to send a meal?"

Zhang Yutong sat down in the secondary seat next to Lan Jie's main seat in a huff, she opened Lan Jie's physics homework book, and learned Lan Jie's solutions and answers to her own physics homework book with a learning mentality.

"The Coriolis thinking question that Mr. Tang left yesterday turned out to be solved in this way, and I learned it. Learning made Zhang Yutong fulfilling, and learning made her forgive Lan Jie's rude attitude.

"Hey, defeated, defeated, defeated by fluorine. "Lan Jie temporarily gave up the plan to kill the chemistry bastard, and ruined his life, don't force it.

"Ranger, thank you. After Zhang Yutong finished studying, he returned the physics homework book to Lan Jie.

Lan Jie took back his physics workbook, and he noticed a detail: "Zhang Yutong, have your bangs been repaired?" This kind of bangs is more suitable for you, highlighting the delicacy of your facial features, and there is a delicate and exquisite style of vigorous girlish painting. ”

Zhang Yutong said beautifully: "Oh, don't care about this superficial external beauty, the school is focused on academics." Lanjie, I'm back in my seat and let's go after school. ”

"I refunded the movie ticket, and I have something at home today. ”

"This ......" Zhang Yutong was quite surprised, how can he say that he will retreat?

When the class bell rang, Zhang Yutong returned to her seat with some loss.

It's normal for Lan Jie to have something to do temporarily, who doesn't have something urgent?

Zhang Yutong suddenly remembered that her family also had an urgent matter tonight, and she operated her mobile phone to refund the movie ticket during the recess.

The last class in the morning of the second and third classes is physical education, the first half of the class is Tai Chi, and the second half of the class is free to move.

During the free time, the boys mostly played basketball and football, and the girls did everything.

Langer is very fond of sports and has been doing it for a long time.

It should be added that in Langer's mind, sports is not a tool, sports is a person.

The status of physical education is slightly lower than that of physics and mathematics, and higher than all other tools.

Normally, Ranger makes the most of every second of PE class to do sports.

But today Ranger did have something to do, he gave up his free time in physical education class and strode back to the school building.

"Lan Jie, where to go!"

A black-faced macho man shouted, he was a physical education teacher Wei.

Lan Jie replied, "I'll go back to the classroom to read the book, Mr. Wei." ”

Teacher Wei was puzzled: "You got the first place in the class in the cultural class, and you still work so hard to study for a while? ”

Lan Jie sighed, "Hey, there are many top sheep students, and I am just one of them. The clouds are flying and the wind is blowing, I have been in the dark, gradually tending to mediocrity, only to forge ahead and rush, otherwise the previous efforts will be wasted. ”

Teacher Wei suddenly melancholy: "There are a set of small words, but it is indeed such a truth, when I was so old as you, I was too playful, I was not admitted to a good university, and in the end I could only come to be a physical education teacher." ”

"Teacher Wei, I'm leaving, bye-bye. ”

Lan Jang trotted all the way back to the second and third class classrooms, and the gift that came with the Coriolis cards required him to study for at least 13 hours a day.

'I have to complain about Coriolis, you dude forcibly compressed my play time. If you haven't had enough, how can you be in the mood to study?'

After complaining, Lan Jie carefully studied the chemistry materials, and he seemed to have found a trace of inspiration.

On the seven-a-side football field, seven boys from Class 2 and 3 are playing a friendly match with boys from Class 2 and 5.

Some girls are watching the game from the sidelines, and some of them have a crush on one or more boys playing football, or they have established a certain degree of friendship with one or more boys.

Another part of the girls happened to pass by the seven-a-side football field, this point to have lunch is too early, and they don't want to go back to the classroom to study, just look at the excitement, comment on her, she and him, whether he has a sense of CP, if there is a blessing, if not, call the police.

"My God, Wu Zihan is too vegetable! Leaking ball under the crotch, Wu Zihan, you're angry with me!"

Zhang Yutong is the third type of girl, she watches boys play football because she likes to watch boys play football.

Wu Zihan, the goalkeeper of the second and third classes, conceded 5 goals, and the second and third classes temporarily fell behind 0-5.

The first time I was shot through my crotch was an accident, understandable and forgivable.

Wu Zihan was shot into the crotch ball by the opponent five times in a row, and the crime was unforgivable.

"There is gold under the man's crotch, and he continues to wear the crotch and has spicy eyes! Habitual crotch leakage, Wu Zihan, Wu Zihan, you have lost the face of our second and third class boys!

Zhang Yutong took out his mobile phone and prepared to call his brother.
