This time IChO is indeed more difficult and has a large amount of questions. If it were Qin Ke half a year ago, it would have taken two hours to complete. However, in August, Qin Ke's brain development limit increased by 50%, which made After upgrading his biology and chemistry subjects, his science talent was raised to 480 again. Subsequently, the physics and mathematics subjects were upgraded, and his science talent was raised by another level, now reaching about 560.

He is not far away from the current upper limit of 600 for his science talent.

Qin Ke didn't know how high the science talents of science giants such as Hawking, Einstein, Gauss and the Prince of Mathematics were, 600? Or even higher? But he estimated that sooner or later he would catch up with or even surpass them.

While Qin Ke was thinking about all of this, he left the examination room without noticing Huang Wei, a small character.

For Qin Ke, there are too many such garbage clowns, and it is enough to slap him in the face with his grades. If he really cares about them and quarrels with them, it will only lower his own quality.

But Qin Ke's indifference and disregard as he walked directly past Huang Wei without even looking out of the corner of his eye made Huang Wei even more jealous, hateful and resentful.

He was jealous of why Qin Ke was such a genius and could complete the entire paper so quickly, hated himself for not being able to do it, and resented why Qin Ke came to participate in this IChO... Anyway, he was right, and it was others and the world who were wrong. .

The more Huang Wei thought about it, the more unbalanced his mentality became, and the more difficult it became for him to answer the questions. Four hours later, he could only manage to answer six questions, and he was not sure he could get many of the questions right, and even skipped some of them directly.

Huang Wei's back was covered with sweat, and he felt his lips were dry, his tongue was dry, and his whole body was uncomfortable. He scribbled on the draft paper irritably, then unscrewed the cap of the mineral water bottle and drank a heavy drink to himself, and then he felt better.

Suddenly, he saw another person holding up the HELP sign. The invigilator passed by, and then a beautiful girl wearing a single ponytail wearing the Xia national team left the examination room lightly with a scent of fragrance.

Even Ning Qingyun completed the entire paper and submitted it in advance?

Huang Wei's calm state of mind just now completely collapsed. His eyes were red and he was breathing heavily. He suddenly crumpled the answer sheet into a ball and raised his hand to throw it out——!

But the paper balls were at his fingertips. Huang Wei suddenly thought that when he was studying and living in Canada, the only thing that made people think highly of him was his chemistry score. If this answer sheet was thrown away, his theoretical score in IChO this time would be certain. Zero, how will he face his classmates, teachers and people around him after returning to Canada?

Do we have to go back to the days of being discriminated against and ridiculed?

In the end, Huang Wei almost suffered internal injuries, but he still gritted his teeth and retracted his hand, then flattened the answer sheet with force.

An invigilator noticed something strange about him and came over to warn him not to disturb the discipline of the examination room, otherwise his grades would be invalidated and he would be kicked out of the examination room. Huang Wei had to apologize humbly and with a smile on his face.

The more he thought about it, the more frustrated he became. In the end, he just let out a long sigh, and then continued to answer the questions with a face ashen as death...

In fact, he also knew that the marking teacher would not give him a high score just based on this messy answer sheet. After all, the first impression of the paper on the marking teacher was very important. Otherwise, why would he need a scratch paper?

Why was it not the scrap paper that I crumpled into a ball when I was so angry just now?

Huang Wei felt regretful, resentful, angry and uncomfortable. This time, he completely failed the IChO exam and had to burn incense to get a silver medal.

…

After a day's rest, on the morning of the third day, Huang Wei finally adjusted his mentality, cheered up again, and went outside the experimental examination room early to wait for the exam.

Due to the limited space, the chemistry experiment exam is divided into two batches, morning and afternoon, both of which are 4 hours long. The experimental questions are also divided into two papers, AB, with the same difficulty. The exam times are determined by teams and drawn lots.

Huang Wei's Canadian team was drawn in the morning, from 8 a.m. to 12 p.m. By the way, the afternoon exam was from 12 a.m. to 4 p.m.

He roused himself and followed captain Tillison into the laboratory. Unexpectedly, he saw the person he least expected to see - the Xia national team headed by Qin Ke and Ning Qingyun!

There are a total of four laboratories for the exam, and they can all be grouped together. Huang Wei can only explain it with the metaphysics of "enemies meet on narrow roads", but he can't say a word.

God's prank?

forgive me!

Seeing Qin Ke talking and laughing with his teammates, Huang Wei's face looked strange again, and the gloomy feeling of being shadowed by the god of learning came to his heart again.

But the whispered conversation between the captain and the vice-captain next to him gave Huang Wei renewed hope.

Yes, when it comes to experimental conditions and experience in experimental operations, how can high school students in Xia State be as good as them? I heard that the laboratory conditions in Xia State schools are very poor, and you often have to go to high school before you have the opportunity to encounter experiments.

Equipment, and in Canada, even primary school students can go to the laboratory for interesting chemistry experiments, let alone junior high and high schools.

Come on, the experimental score accounts for 40% of the total score, you still have a chance! You must not lose to the Xia Kingdom representative team!

Huang Wei took a deep breath and calmed his mind.

Soon all the candidates put on their lab coats and goggles. After the on-site proctor explained the precautions for the experiment, the experiment began.

The experiments are conducted individually and cannot be communicated as a team. Candidates from the same country will be scattered to different areas to conduct experiments individually.

One invigilator corresponds to four candidates and is responsible for grading and handling emergencies.

Moreover, there are cameras everywhere in the laboratory, and two invigilators responsible for the second review will watch the video in the background. Basically, any mistakes will not escape their eyes.

After the experimental exam is over, the three invigilators on site and in the background will score together, and the average will be the candidate's final experimental score.

Huang Wei forced himself to concentrate, carefully review the topic, and then started to make an experimental plan.

The first is an experimental question on dye production, which involves many knowledge points, including dye strength, molar digestion coefficient, diazotization reaction, cationic dyes, absorption spectrum curves, three-stage method, etc., which is quite difficult.

The topic requires the completion of a full chemical reaction design plan for a specified dye, so as to develop a green dye that can be standardized and scaled.

Huang Wei spent about 40 minutes completing the design and then started the formal experiment.

The first step is to produce chlorine gas. Chlorine gas is generated through the reaction of manganese dioxide and concentrated hydrochloric acid. This is a very basic experiment that no junior high school student can do wrong. Huang Wei completed it with almost no effort.

I had just recorded the data and was about to proceed to the second step when I suddenly heard a middle-aged male invigilator with a high nose not far away asking: "This student, do you need anything?"

Huang Wei looked up and saw a candidate holding up a "HELP" sign. To his surprise, it was Qin Ke who held up the sign!

Huang Wei couldn't help but take a second look and heard Qin Ke say in English: "Teacher, I want to change my concentrated hydrochloric acid."

The invigilator with a high nose bridge said unexpectedly: "Is there something wrong with your bottle of concentrated hydrochloric acid? Why do you need to replace it?"

"The concentration of this bottle of concentrated hydrochloric acid does not meet the standard. I think it cannot reach the standard concentration range of 36% to 38%, and it is not consistent with the 36.5% concentration required for this experiment."

The invigilator with a high nose bridge said displeasedly: "All the concentrated hydrochloric acid in this laboratory is filled from the same bucket, and all our experimental equipment and chemical materials have been inspected by three standards before the exam begins.

It is impossible for the concentration discrepancy you mentioned to occur. Please continue the experiment..."

Qin Ke shook his head and said: "I don't know about other people's, but my bottle of concentrated hydrochloric acid is definitely not up to standard. I just did a mental calculation. According to the reaction time and the concentration of chlorine generated, the concentration of this bottle of concentrated hydrochloric acid is only 29.5%. Since this experiment

We are required to design the most appropriate solution that can be standardized and scaled, and the first thing we must ensure is that the experimental materials meet the standards."

He fought hard and said: "This bottle of concentrated hydrochloric acid with only a concentration of 29.5% cannot verify my experimental plan, and the results will also produce errors beyond the reasonable range. I refuse to use such concentrated hydrochloric acid for experiments! According to the regulations of the examination room,

Experimental materials that candidates have questions about can be replaced, and I request to exercise my rights!"

The high-nose invigilator was obviously annoyed by his rebuttal. He snorted, forcefully opened a spare cabinet next to him, casually took out one of the two bottles of concentrated hydrochloric acid inside and said, "I'll say it again, all our experimental equipment,

Chemical materials are inspected by three standards before the start of the exam. It is impossible for the concentration discrepancy you mentioned to occur. But it is your right to request replacement of materials, and you only have this right."

After that, he put the concentrated hydrochloric acid in front of Qin Ke.

"Please continue the experiment immediately, otherwise I will treat you as disrupting the order of the examination room and invalidate your score on this question!"

Listening to the obviously dissatisfied voice of the high-nose invigilator, Huang Wei felt secretly happy in his heart, Qin Ke, Qin Ke, you are so picky, how come I didn't find anything wrong with this concentrated hydrochloric acid? I will be scolded this time, right?

?It’s best to scold you until your mentality collapses and the experiment goes wrong!

He continued with the second step of his experiment while regretting it, but a few minutes later, he heard the high-nose invigilator ask again: "Student, do you have any more questions?"

This time it wasn't just Huang Wei, the entire examination room students looked over curiously.

Qin Ke pushed back the concentrated hydrochloric acid in his hand: "Teacher, the concentration of this bottle of concentrated hydrochloric acid is also the same 29.5%, which is not up to standard! I refuse to use it!"

The invigilator with a high nose bridge had an angry look on his face, and stared at Qin Ke with his blue eyes: "I told you, all the concentrated hydrochloric acid here is filled from the same barrel, and after three inspections, there can be no quality problems!

You can refuse to use it, but I will give you zero points for this question! Let me ask you one last time, do you insist on refusing to use it?"

Qin Ke was silent for two seconds, and then said firmly: "Yes. The most important thing in chemical experiments is rigor, which includes rigorous operation and rigorous materials. Using chemical materials that do not meet the requirements will affect the final experimental results and fail to meet expectations.

The effect may even be unexpected. I refuse to use this batch of concentrated hydrochloric acid, even if I get zero points for this question! However, I will reserve the right to appeal after the exam!"

The high-nose invigilator said coldly: "Okay!" He went directly to get Qin Ke's ID, copied his name in his notebook, then looked around, and asked with a frosty face: "Who else thinks

The concentrated hydrochloric acid provided by our laboratory does not meet the standards and you refuse to do this experiment?"

Everyone was frightened by his anger and coercion and lowered their heads. Huang Wei was even more overjoyed. Sure enough, the sky is the limit! How could there be something wrong with this concentrated hydrochloric acid? This is an IChO experimental test, the best in the world.

High school chemistry competition scene!

But Qin Ke actually got dizzy and was stubborn. He even contradicted the invigilator and gave up the score for a big experimental question! That was a full 30 points!

Even if he can do the second and third questions completely correctly, he will only get 70 points!

But almost no one can get perfect marks in the experiment!

In other words, Qin Ke's experimental exam this time was only 60 points at most!

Thinking of this, the smile on Huang Wei's lips almost broke out.

There was silence all around, and suddenly a little hand as white as jade was raised, and then a girl's calm voice sounded: "I. The concentrated hydrochloric acid in my hand does not meet the standards. I just observed the rate of chlorine gas generation.

There is an abnormality with the concentration, which is obviously a quality problem with the concentrated hydrochloric acid. I refuse to use such concentrated hydrochloric acid."

Ning Qingyun of the Xia Kingdom Team!

The candidates around them all made an uproar in a low voice. When they saw the invigilator with a high nose bridge passing by with a dark face, he copied Ning Qingjun's name without saying a word, then looked around the crowd and said coldly: "Who else refuses to use it?"

An Xianzhi and Shen Xilin looked at each other, gritted their teeth, and raised their hands: "We also refuse to use it."

This chapter is not over yet, please click on the next page to continue reading the exciting content! "Very good, your Xia national team is very united."

Looking at the high-nose invigilator who was almost going crazy, all the candidates were both amused and a little gloating that this time the Xia Kingdom representative team was completely wiped out!

The invigilator with a high nose bridge gritted his teeth and asked three times, "Is there anyone else?"

No one raised their hands at the scene.

"Very good, now I announce." The high-nose invigilator picked up the small book in his hand and read loudly: "Qin Ke, Ning Qingjun, An Xianzhi, and Shen Xilin of the Xia Guo team, the four first

The score for the question is - 30 points, and the rest, 0 points!"
