089 Mg2B2O4(OH)2

In the chemistry teaching and research room, Li Zheng, Lin Yujing, and Xu Mengxi came to answer the questions with thunderous force.

But as soon as I hit the first question, I felt like I was stuck in the Bagua array.

[1. Write a chemical reaction equation according to the conditions]

[1-1: Industrially, boric acid is prepared by reacting ammonium bicarbonate and forsterite (mg2b2o4(oh)2) in aqueous solution]

Li Zheng: What the hell is this? Is my chemistry level really 150+?

Xu Mengxi: Don’t panic…don’t panic…analyze carefully…step by step…don’t panic…no…no way!

Lin Yujing: Well...>.

However, this is only the first sub-question of the first major question.

The simplest question.

Correct answer, only 2 points.

Li Zheng now knows why Sun Leyang said that if he could score 10 points, he would be a boss.

Although the problem was so terrifying, Li Zheng still did not drive at 56x speed.

This time, he just wanted to know his true level.

Go home and start again.



The three of them worked hard to solve the problems and had no idea of ​​time at all.

Until the preparation bell rings.

Li Zheng raised his head in fear.

Are you kidding me?

Only done 1/4.

But I heard Yu Hong say: "Teacher Sun has gone to class. I have already said hello to Teacher Tang. You continue to do it. The exam time is three hours, don't worry."

Li Zheng breathed a sigh of relief and glanced at the two people next to him.

Xu Mengxi’s progress in answering questions was similar to her own.

Lin Yujing lay on her side on the table and weakly opened the second interview paper.

Li Zheng stared.

what's the situation?

Have you started answering the second question, are you more than half done?

Did you even study chemistry in college on the sly?

So damn cunning.

Li Zheng didn't have time to think too much and returned to the roll of noodles again.

[In the solution of metal ion m3+, add acid hmx, control the conditions, you can get different precipitates. ph 1, get the precipitate a (m2xn·yh2o, y 10)...]

Damn you.

What on earth is this talking about...

No matter what, just do it.



Unknowingly, the three of them turned into question-solving machines.

The bell rang again and again, but they turned a deaf ear.

Finally, Yu Hong clapped his hands: "Okay, Teacher Sun has been waiting for a long time, three and a half hours."

Boom.

Lin Yujing took down the pen and lay down in front of the table. She scratched her head with both hands, scratching and shaking her head, and she burst out with a painful moan she had never experienced before: "Ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh but aaaaaaaaaaaaaaaaaaaaaaaaaaaaa!

"

Next to him, Xu Mengxi's hand softened and the pen fell to the ground.

Staring at the white wall, his eyes were empty and his whole body was exhausted.

It seems like a wasted life.

Li Zheng's mind was already in a state of confusion. After throwing away the pen, he leaned back on the chair blankly and breathed heavily.

It's like the bomb squad just cut the red thread.

Survival after disaster.

At the same time, the corners of Li Zheng's mouth were twitching, and at some point, he silently recited the meditation mantra that could only be activated when he learned to crack: "Nawu, drink Luo Tanna, do Luo Yeye... Nan

Wu, Ajuye...Polu Jiedi...Shuoboloye..."

no doubt.

All three of them collapsed.

When I did the questions, I failed.

Yu Hong also saw this situation for the first time and was amazed.

"Hehe." Sun Leyang smiled steadily, "It's my first time doing a competition, it's like this, hehe."

Under Yu Hong's urging, Lin Yujing and Xu Mengxi helped each other towards the toilet.

Li Zheng's crutches were so weak that they became weak.

When I was urinating, the crutch fell to the ground before I could hold it firmly.

Boom!

Li Zheng smashed the wall hard.

Is this the realm of genius...

It’s so… so damn hard…

It’s harder than taking the Mathematical Olympiad test in elementary school.

That Mathematical Olympiad paper could still score at least twenty or thirty points.

This one is really not even 10 points confident...

What else is there to challenge yourself...to compete with masters...

They are all perverts! Those people playing competition are all perverts!

With such a heavy heart, Li Zheng almost burst the urinal.

After finishing the work and coming out, he found Lin Yujing and Xu Mengxi leaning against the corridor window, shivering.

"Well..." Lin Yujing shakily took out a piece of mint candy and tore the package several times, but couldn't tear it open. She was so angry that she threw it to the ground, holding her head and moaning wildly.

Xu Mengxi stared blankly out of the window without saying a word.

Li Zheng walked over with a crutch, made a difficult movement of leaning over to pick up candy, then steadily tore open the wrapping paper and handed the white candy to Lin Yujing: "Here."

Lin Yujing was stunned for a moment, and after struggling for a while, she still reached out to pick it up.

But Li Zheng suddenly took it back, frowned and said, "I seem to have...not washed my hands...forget it, just eat it yourself."

He then threw it into his mouth.

"?!"

Lin Yujing wanted to tickle someone.

"Don't be so stingy." Li Zheng raised his hand and said, "I gave you so many medicines, but you still get breathless after eating a piece of candy."

"Ha!" Lin Yujing couldn't bear it anymore, so she went up and scratched Li Zheng's arm.

"You're so scratchy..." Li Zheng felt pain and quickly took two steps back with crutches.

Although, when I first went to the toilet, there was a lot of negative energy.

But he has already gone out.

"Maybe, I will get zero points." He said frankly to the two of them, "But I will still participate, even if I study on my own."

Lin Yujing was so frightened that she shrank into a corner, closed her eyes and covered her ears, refusing to hear anything related to the competition.

Xu Mengxi held on to the window sill and turned to look at Li Zheng: "You can do it, after all, there is still a year."

"No, I'm only participating this year." Li Zheng tried his best to sound modest in his tone, "I checked the time. I will participate in the physics and mathematics competition next year."

"Uh 5555..." Lin Yujing was so frightened that she kicked her legs so hard that her voice was trembling. She looked at Li Zheng as if she were looking at a devil.

"You are really... strong enough..." Xu Mengxi shook her head, leaned against the window and sighed, "I can't do it... this is my chance. I guess the standard for saving the second grade is about 40 points...

…It’s unlikely…”

If it were normal, Li Zheng would definitely want to encourage him.

But it's different now.

Even though he is keen on sadistic topics, he also understands what real horror is.

This is no longer as simple as despair, but killing all your enthusiasm for a subject.

"Well, if you can't do it, don't force yourself." Li Zheng stepped forward to comfort him, "Give your best in the college entrance examination and get a 985."

"Let me lend you some good words..." Xu Mengxi turned to look at Lin Yujing, "Jingjing, what you did... will probably be worth..."

Lin Yujing closed her eyes and shook her head>., refusing to remember.

The three of them kept calm for a long time before they finally relaxed a little and returned to the chemistry teaching and research room clinging to each other.

Opening the door, Sun Leyang and Yu Hong were sitting quietly, saying nothing.

Why, even their judge can't stand it?

When the three of them came forward, Sun Leyang shivered, stood up and stared at Lin Yujing.

"Lin Yujing, you are already provincial level two."

"???"
Chapter completed!
