Ranger bought a 6 yuan breakfast of latte croissant at KFC at the gate of Sheep, and the signature of FPX.crisp was printed on the latte cup.

Ranger decided to give chemistry and biology more dignity, especially chemistry, which is very closely related to physics, and physics and chemistry are often bound together to lead a path.

The tool status of chemistry is impossible to change, but tools are also divided into intelligent tools and original tools.

‘Chemistry, I, Ajie, have great compassion to promote you as a smart tool. Please don’t let me down.’

Lanjie came to the classroom of Class 2 and 3, and he greeted Li Zihan enthusiastically: "Li Zihan, morning! You come to the classroom so early every day, 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 front of Lanjie in the row. He studied the math elective textbook without raising his head, and did not look at Lanjie.

"Brother, I am almost twenty years old at the age of sixteen or seventeen. I will join the party in two years. Can you be more mature?" Langjie took the lead and drank lattes and ate croissants.

Li Zihan couldn't help but turn around and asked, "Lanjie, why can you grow to about 1.8 meters in length when you eat these junk food every day?"

Langjie shared his experience: "What you eat doesn't matter, the key is to exercise, sports promote growth. Li Zihan, you have to exercise more, and you may not have enough exercise for 10 hours a week, right?"

"Langjie, you encouraged me to exercise all day long, but you studied secretly. Haha, you are too scheming, you are very worried that I will surpass you in learning."

"Beyond me? Then you can surpass me. I wish someone in the class could surpass me, hehehe."

Li Zihan's childish remarks reflect an immature mind, which made Ranjie very happy early in the morning.

The first class was held at 8 o'clock, and it was now 7:30. Ranger kept his promise and gave chemistry more dignity.

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

The main oxidation states of cl,br,i are -1,1,3,5,7. The oxygen-containing acids of halogen are all strong oxidants. Except for the -1 and 7 oxidation states, other oxidation states are prone to disproportionation reactions.

Huh?

So strange.

Why do you just pick up f from the chemical elective and come from a line in a row?

Is this a negligence when writing the teacher’s layout, or is it a hidden secret?

Ranger fell into deep thought, and he found that f was not simple.

‘Chemistry, you’re getting more and more annoying. You’re just a tool. Why do you have so many human thoughts?’

Langjie turned to the next page. The explanation in the chemical elective is that because the radius of f- is the smallest and the electronegativity is the largest, f- as a ligand can stabilize the central element in the high oxidation state and achieve high coordination numbers, such as sbf5, uf6, if7, ruf8, etc.

‘Hey, 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, and are colorless?’

Because there is no physical object, Ranjie can only do paper articles. He tries to disassemble pairs of electronics, but this thing is not easy to disassemble.

Ranger was sweating profusely, and the draft was filled with electrons inspired by the P-orbit.

Damn, I can't handle it!

Rangerton felt frustrated, and after the frustration, he became more and more courageous. He would never give up until he killed the little bastard of Chemistry.

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

“Not available.”

"Is it okay to borrow the physical homework book?"

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

"What a rude attitude, are you a beggar?"

Zhang Yutong took the seat next to Lanjie's main seat in anger. She opened Lanjie's physics homework book and learned Lanjie's solutions and answers into her own physics homework book based on a learning attitude.

"This Coriolisian thinking question left by Teacher Tang yesterday turned out to be solved in this way. I learned it and learned it." Learning made Zhang Yutong fulfill her, and learning made her forgive Ranger's rude attitude.

"Oh, I lost, I lost, I lost to Fer." Lanjie temporarily gave up the plan to kill the chemical bastard, and ruined his life if he couldn't.

"Lanjie, thank you." After Zhang Yutong finished studying, she returned the physics homework book to Lanjie.

Ranjie took back his physical homework book and noticed a detail: "Zhang Yutong, have your bangs been repaired? This bang is more suitable for you, highlighting the exquisite feeling of your facial features, and has a delicate and exquisite style of a girl."

Zhang Yutong said happily: "Oh, don't care about this superficial external beauty. School is the most important thing. Langjie, I'm back to my seat and go together after school."

"I've refunded the movie ticket, I have something to do at home today."

"This..." Zhang Yutong was quite surprised. How could he retreat just by saying that?

The class bell rang, and Zhang Yutong returned to her seat with some consolation.

It is normal for Ranger to have something to do temporarily, who has no urgent matters?

Zhang Yutong suddenly remembered that there was something urgent tonight at her family. She operated her mobile phone and refunded the movie ticket during the break.

The last class in Class 2 and 3 is physical education class. The first half of the class is Tai Chi, and the second half of the class is free to move.

During free time, most boys play basketball, football, and girls do everything.

Ranger likes sports very much and engages in physical exercise for a long time.

It should be added that in Lanjie's mind, sports are not tools, sports are people.

Sports is slightly lower than physics, mathematics, and higher than all other tools.

Under normal circumstances, Ranger will make full use of every second of physical education class to do exercise.

But Lanjie did have something to do today. He gave up the free activities of physical education classes and strode back to the teaching building.

"Langjie, where to go!"

A black-faced man shouted loudly, he was Teacher Wei of Sports.

Ranjie replied: "I'll go back to the classroom, Teacher Wei."

Teacher Wei showed his doubts: "You are the first in the class in the cultural course, and you are still working so hard to review your books? You can do it freely and don't play for a while? This is not in line with your usual style."

Lanjie sighed and said, "Oh, the top students in the sheep are gathered, I am just one of them. The clouds are flying and the strong wind is rising. I have become lost in the crowd and gradually become mediocre. I can only move forward and rush forward, otherwise all my previous efforts will be wasted."

Teacher Wei suddenly felt sad: "There are a lot of small citations, but that's true. When I was so old, I was too playful and didn't get into a good university. In the end, I could only be a physical education teacher."

"Teacher Wei, I'm leaving, bye."

Ranger trotted back to Class 2 and 3 classrooms. The talent attached to Coriolis' cards required him to study for at least 13 hours a day.

‘I have to complain about Coriolis, you guy forced me to squeeze my time to play. If you didn’t have enough fun, how could you feel like studying?’

After complaining, Ranjie carefully studied the chemical materials, and he seemed to have found a trace of inspiration.

On the seven-person football field, seven boys from Class 2 and 3 were playing friendly matches with boys from Class 2 and 5.

Some girls watch the game on the sidelines. Some of them fall in love with someone or some boys playing football, or they have established a certain degree of friendship with someone or some boys, add some fuel, call, consolidate friendship, and routine operations.

Another part of the girls happened to pass by the seven-person football field. It was too early to have lunch at this order and didn’t want to go back to the classroom to study. So I just watched the fun and commented on whether she and him had a sense of CP. If there was a blessing, I would call the police if there was no.

"My God, Wu Zihan is too bad! The ball is leaking under his crotch, Wu Zihan, you are so angry!"

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 Class 2 and 3, lost 5 goals, and Class 2 and 3 temporarily fell behind 0-5.

The first time I was shot through the crotch was an accident, which is understandable and forgiven.

Wu Zihan was shot into the crotch-piercing ball by the opponent for five consecutive times, and his crime was unforgivable.

"There is gold under the crotch of a man, and he keeps wearing the crotch and is so irritating his eyes! He is used to leaking balls under his crotch. Wu Zihan, Wu Zihan, you have lost all the face of the boys in our Class 2 and 3! Where is Lanjie, where did this guy go?"

Zhang Yutong took out her cell phone and prepared to call her brother.
Chapter completed!
