Seriously, Li Weihong is quite partial to this Miss Wu Di, even if the other party's chemistry grades are very average, but he can't stand him and accepts a lot of gifts, before the start of this semester, he was fortunate to be invited to the "prosperous age" for a meal, and the money for this meal is equivalent to his two months' salary......

Although Li Weihong is also an experienced old teacher, he is not as "stylish" as English teacher Huang Ying, he is very tactful, so even if his teaching level is average, he became the head of the chemistry teaching and research group with his qualifications and connections.

Moreover, Wu Di's appearance is also very pleasing, he always favors beautiful girls, and he likes to take the initiative to point out chemical problems to these girls, but because of this, Li Weihong is definitely a lewd pervert in the eyes of boys, even if he never dares to do anything to female students.

But at this time, Li Weihong saw that Wu Di was so unscrupulous in class, even if he favored Wu Di again, he couldn't turn a blind eye to it, and at this time he was talking about an example question he had assigned-

Potassium iodate (KIO3) and potassium iodide can undergo the following reactions in acidic solutions. Please indicate the direction and number of electron transfers in the reaction equation and indicate the oxidant and reducing agent.

5KI+KIO3+3H2SO4=3I2+3K2SO4+3H2O

In this reaction, the ratio of the amount of oxidizing agent to the reducing agent is 1/5. Q: When there is a transfer of 10mol electrons, what is the amount of I2 generated?

Li Weihong did not directly call Wu Di's name, but said to the class: "Everyone use scratch paper to do it below, and I will ask someone to answer this question later." ”

He originally thought that after he did this, Wu Di could return to the classroom from a distraction, so that he could return to the class. He didn't need to mention Wu Di's name, but after the other party stood up, he couldn't answer the embarrassment of this question.

But what made Li Weihong very helpless was that even those boys who were inattentive in class began to lower their heads after he said this. took out the scratch paper and calculated, regardless of whether these boys were pretending or not, at least the attitude was satisfactory to him, but Wu Di was still wandering in the world, although her doppelganger Wu Di had already helped her think of the answer to this simple chemistry problem.

There is no way, so I can only order Wu Di to answer the question after this, and if she can't answer it at that time, remind her to concentrate in class in a kind tone. Hopefully she'll pay attention next time...... Li Weihong thought so.

In fact, although he prefers a beautiful girl like Wu Di, but the other party is so distracted in his class, it also makes him feel a little unhappy, in high school, probably as long as he is a teacher, unless he is irresponsible, he hates students who don't listen carefully in class. That will make the teacher feel that he has done useless work and that the lecture is not engaging. Not being respected by students.

Soon, Li Weihong said that the time was up, and he wanted to ask someone to get up to answer this question, and for a while the class was silent, and the atmosphere became a little tense, especially the boys. Because if they stand up and can't answer, they will be criticized mercilessly by Li Weihong, and as for girls, they are treated much better than boys.

"Wu Di, get up and answer." Li Weihong confirmed that she had used the gentlest tone.

As a result, Wu Di still did not react. It's not that she's pretending not to hear it, it's that she really isn't, and her style is to focus on one thing and completely immerse yourself in your own world.

The eyes of the whole class suddenly moved to Wu Di, and they couldn't see that the eldest lady was completely distracted!

The students had different ideas:

"The eldest lady deserves to be the eldest lady, and even the posture of the mind is so beautiful and picturesque, just like my department (Kobe), although the iron is striking when the back-to-back jumper is struck, but the posture is picturesque, which also has a reason to go black? Those Kohei are so nasty! "That's the idea of that basketball named Zhang Bo, who is a super Komi, a die-hard fan of my lake.

"It's completely understandable to wander your mind! And the mind wanders so beautifully...... The most important thing is that this should have been an activity class, and Li Weihong has to grab even these ten minutes on a dog's day, which is so hateful! "That's what most guys think.

"Teacher Li should have noticed that Wu Di was distracted, right? But he still called her in such a gentle tone, he was too tolerant of her, if it was Mr. Huang, he would have thrown the chalk out directly. Some of the girls thought.

"The sinister girl is absolutely finished this time, the whole class has seen her ugly appearance, it seems that there is really good and good to repay evil, it's not that the time has not come, ahahaha......" Wang Qi was ecstatic in her heart, but her face was very calm, she deliberately didn't remind Wu Di, just hoping that Wu Di's "ugly state" would last longer!

She naturally didn't understand that in this world of looking at faces, goddesses will never be ugly, and the psychological activities of many boys prove this.

"The teacher called you to answer the question." The reminder from Wu Di finally woke up Wu Di, and she also had the answer to the question in her mind.

Under the gaze of the whole class, when she stood up, she was still confused in her eyes, and she looked like an innocent girl, and she had killed countless young people who had been secretly in love for a long time.

Li Weihong sighed slightly, but still said kindly: "Okay, classmate Wu Di, you ......"

Before he could finish speaking, Wu Di began to report a very standard answer-

"The oxidant is KIO3 and the reducing agent is KI. In this reaction, the ratio of the amount of oxidant and reducing agent is 1/5, iodine element is both an oxidation product and a reduction product, six moles of iodine atom in three moles of iodine element, one mole is derived from potassium iodate, and five moles are derived from potassium iodide. 5mol potassium iodide was used as a reducing agent, and the iodine ions increased from negative monovalent to zero valence, and 5mol electrons were lost; 1mol potassium iodate is used as an oxidant, and the iodine in the iodate group is reduced from positive pentavalent to zero valence, and 5mol electrons are obtained. When 5mol of electrons is transferred in the reaction, 3mol of iodine is generated. So when 10 mol of electrons are transferred, the amount of I2 produced is 6 mol. ”

Wu Di's voice is very beautiful, and her calm and unhurried tone when reporting the answer also made many people admire in their hearts, completely forgetting that Wu Di had just lost her mind, and when they came back to their senses, they naturally felt very incredible in their hearts, and they were so distracted and crazy, but they could answer so accurately, which is also too powerful, right?

Li Weihong was still trying to comfort Wu Di, but before he finished speaking, he heard a completely correct and detailed answer, his mouth was open there, and he didn't know what expression to use on his face, obviously because he didn't expect that Wu Di would be able to counterattack in this situation.
