I slept too much in class the day before yesterday, which led to not sleeping well last night. The chain reaction led to sleepiness in class today!

After hearing the words, the chemistry teacher's face turned black. She said angrily, "Yang Tian, right? You've done the right thing on the blackboard. I won't embarrass you."

Her beautiful eyes were cold, and then she said, "if you make a mistake, you should wait for yourself to explain to your head teacher why you have been standing in chemistry class."

Yang Tian took a look, and a chemistry multiple choice question was written on the blackboard

In a constant volume closed container at a certain temperature, when the following physical quantities of the substance do not change, it is impossible to explain that the reaction a (s) + 2B (g) C (g) + D (g) has reached equilibrium

A. Pressure of gas mixture

B. Density of gas mixture

C. Average molecular mass of gas

D. Concentration of substance B

Everyone laughed at this, because it seems that the chemistry teacher is deliberately embarrassing Yang Tian.

This topic, just explained by the chemistry teacher, is the latest knowledge point, and the number of people in the whole class will not exceed one hand.

Of course, Yang Tian is definitely not included in this one handed number.

Although he is a genius in mathematics and Chinese, so what? How can the other party know this problem before he studies it.

Glasses man disdains to laugh at Yang Tian. He is the monitor of chemistry class. He can't do this subject. How can the other party do it.

Yang Tian said: "so simple? Teacher, are you sure you don't want to change another question? I feel that you can't help me with this childish question, and I can't vent your anger! "

Yes, I really can't vent her anger. The chemistry teacher's lungs almost burst. Her chest was puffing violently, and her hands were crushing the chalk.

When people heard Yang Tian's response, they laughed directly.

"Hum, I'm not afraid to flash my tongue when the wind is strong. The difficulty of this question is beyond your imagination." he

Another sneer repeatedly: "sensationalism, this time, if he does right, I live day five electric fan."

Others disdain to say: "what are you, if he does right, I will kneel down for him."

Before he finished his talk, Yang tianqinglang's voice spread all over the classroom.

"The decomposition reaction formula shows that the volume before and after the reaction is constant, so the pressure and the amount of gas are constant, so a is not correct. This question is a!"

Quack!

There was silence in the classroom!

All people are dubious, looking at Yang Tian, said the truth, really?

The man with glasses laughed and said, "Yang Tian, just wait to make a fool of yourself."

He eagerly looked at the chemistry teacher and said, "Mr. Sun, you should quickly announce the results. Yang Tian must have miscalculated."

The chemistry teacher was stunned. There was some incredible color in her beautiful eyes!

After writing and drawing on the paper, Su shirou held her heavy eyes and said, "this question is really a!

Ah?

All of them were surprised, especially the two students who said that the five speed electric fan on the live broadcast day and the two students who threatened to kneel down to Yang Tian were almost ashamed to find a crack in the ground.

Although the chemistry teacher did not say, but Su shirou has said the answer to this question.

For Su shirou, a bully of learning, everyone in the class has no good intentions. Every word he says is the truth!

The chemistry teacher asked some questions: "Yang Tian, I haven't started to talk about this problem. How did you know?"

Yang Tian spread his hand and said: "teacher, I have just said it very clearly. Your problem is too simple. I asked you to change a difficult problem, but you didn't listen to my advice."

Say, want to sit down!

"Wait!"

The chemistry teacher stopped him and said, "well, Yang Tian, I'll give you another question. If you get it right, I won't care if you sleep in the classroom with pillows and quilts from now on."

Wori!

All the people in the classroom dropped their chins.

This female chemistry teacher is really domineering. She can say all these words. If the headmaster hears this, she must be angry.

Yang Tian said with a smile: "thank you for your concern about my sleep, but I don't think I need to bring a quilt and pillow!"

Then he sat on the bench.

"You"

The chemistry teacher was angry. She had never seen such unreasonable students.

She slammed the book onto the desk and said coldly, "Yang Tian, please come to the office for me."

Ha ha, people gloat. Looking at Yang Tian, this boy is completely provoking the gentle chemistry teacher.

Although Sun Xi, a chemistry teacher, is usually kind and doesn't get angry, if she gets angry, it will definitely be a disaster for her opponent.

You heard that last time a social hooligan bullied her students outside school, she went up and knocked out four or five teeth of the hooligan.

This violence is enough to frighten anyone.

Yang Tian has no choice but to follow Sun Xi into the office.

At this time, I happened to meet Han Xiangning who was about to give a lecture in the office.

Seeing that Yang Tian was called to the office by his class chemistry teacher, he must have made a mistake.

Han Xiangning couldn't help but put out her jade hand to hold Yang Tian's ear and said, "OK, Yang Tian, I was still making trouble in my class just now. What's the matter? Now I'm making trouble in chemistry class again? "

Yang Tian's ear was caught by the other side, but he took a cold breath. Hua yanrou's best friend is not so gentle as she looks.

Before he had time to explain, Sun Xi, the chemistry teacher, said with a smile, "Mr. Han, you misunderstood me. This is a question for Yang Tian to calculate. He didn't make any mistakes."

Then he secretly glared at Yang Tian.

Yang Tian said: "yes, Mr. Han, please let go."

Han Xiangning blushed“ Ha, what, Yang Tian? I misunderstood you. Come on, teacher, help you knead! "

Then she rubbed Yang Tian's ears again.

Yang Tian rolled his eyes. Is this a slap to a sweet date?

However, this technique is really comfortable.

After Han Xiangning left, Sun Xi glared at Yang Tian again and said, "the teacher has helped you once. Now I've done this problem honestly."

She handed Yang Tian a chemistry problem on the paper and threatened: "I'm right. I'll let bygones be bygones. I'll tell you the truth later. I don't know if Mr. Han will understand your difficulty when he knows your sleeping theory."

Well, women love revenge.

Yang Tian glanced at the title on the paper, then some doubts: "Miss Sun, did you take the wrong paper?"

Sun Xi took a puff from the corner of her eye, and then hummed, "how can I get it wrong? This is a question I just gave. If I can do it, you just need to answer it happily."

Well, looking at the chemistry teacher playing rogue, Yang Tian sighed: "this topic chooses A."

Sun Xi widened her eyes and said in disbelief: "how do you know that? Why? "

Yang Tian indifferent smile: "the reason is Mongolian."

Sun Xi

She clenched her delicate fist and her forehead was covered with black lines.

Sure enough, he was in Mongolia. He couldn't be right about this topic. It's not something he can touch at his age and education.

But just now, she has revealed her shock, that is to say, the students have already known that he was right.

Sun Xi again took out a piece of paper and wrote a title.

Yang Tian's mouth twitched a little, but said: "teacher, will we still be unreasonable? Didn't you say you'd only ask one question? "

Sun Xi snorted: "am I a teacher or are you a teacher? Do I listen to you or do you listen to me? "

Must, the other party a words finish saying, Yang Tian already did not know how to refute.

She put the new question in front of Yang Tian.

Sun Xi slyly smiles and says: "Yang Tian, aren't you mengdezhun? Then you've got it right for me to fill in the blanks. "

Yang Tian took a look and saw it written

At 25 ℃ and 1.01105pa, 22G CO2 was introduced into 750ml of 1mol-1 NaOH solution for full reaction, and xkj heat was measured. Under this condition, 1 mol CO2 is injected into 2 mol L-1 NaOH solution for 1 l to give off YKJ heat. The thermochemical equation for the formation of NaHCO3 from CO2 and NaOH solution is ()

He looked up at the chemistry teacher“ If I do it, you won't trouble me? "

Sun Xi snorted: "I'm a teacher. I can do it!

"Good!"

Yang Tian nodded, then took up his pen and wrote a series of formulas on the paper.

The handwriting is almost out of the paper!

CO2(g)+NaOH(aq)===NaHCO3(aq); △H=-(4x-y)kJmol-1

When the last stroke came down, he put the carbon pen on the hard wooden table and turned around.

Clean and elegant!

Sun Xi's chin almost fell down, beautiful eyes stare big and round.

Yes, he did it right!

It's impossible. It's unscientific. It doesn't conform to common sense. He shouldn't be able to do this problem.

Sun Xi asks aloud: "Yang Tian, how do you do this problem correctly?"

Yang Tian stops at the door, and a clear voice comes into Sun Xi's ear.

"Mengde!"

"Ah, ah Sun Xi rubs her hair in a mess. You can cover multiple choice questions, but how can you cover filling in the blanks? When she is mentally retarded.

She Jiao said: "Yang Tian, you give me stop, I have a problem here, you give me back to Mongolia once."

At this time, Yang Tian had already returned to the classroom. Never believe a woman's words, especially a beautiful woman------- Back in the classroom, Yang Tian feels that everyone is looking at him strangely. Glasses man, the representative of chemistry course, is definitely on the front line. He sarcastically said: "how about Yang University bully? Was it a lesson from the chemistry teacher? " Yang Tian smiles and doesn't speak. The other side may have said the opposite, it's not Sun Xi who taught him a lesson. But he taught Sun Xi a lesson. Now Sun Xi should be suspicious of life in the office. Seeing that Yang Tian doesn't speak, the man with glasses is more convinced of his own ideas. So, this time, he changed into Ben Gali, went to Yang Tian's side, pointed to Yang Tian again, and said, "Yang Tian, I tell you, in math class and Chinese class, you are in the limelight, but in chemistry class, that's my world, don't think you." before he said anything, Sun Xi, an old chemist, came in and saw and heard this passage from the man with glasses, Her face was gloomy, and she said to her, "shut up!"
