Chapter 41 Principles of Bromine and Iodine Extraction
"Hey, Wang Xiang, can you hear me?" Li Hu hurriedly ran to the computer, and Wang Xiang was sucked into the computer. Judging from the current situation, the screen of the computer is turned off at this time.
The man doesn't flick when he has tears, but he hasn't reached the sad place! Look, Li Hu has already reached the sad place, and he has become a tearful man! Tears had already splashed on the keyboard on the table, but Li Hu didn't know it.
"Ah, Brother Xiang, Brother Xiang, why did you leave without saying a word." Li Hu cried heartbreakingly, and almost howled, "You just said to leave, and you didn't take my brother with me, you still owe me a month of QQ super membership and didn't pay it back, so soon you left Wow!" ”
Dare to love is that Wang Xiang owes Li Hu the money and has not repaid, so he cries like this. If Li Hu's father knew about this, he would not have to scold him, "It's really useless, how did I raise you as a rebel." ”
Just when Li Hu was crying bitterly, the accident happened again.
On the computer screen that sucked Wang Xiang away, a few lines of words appeared at this time:
The fallen god watched over the core of the ark, the peerless power that could bring him back to life. In order to protect the peace of the King's Continent, the heroes embarked on the path of unlocking the core of the Ark. Survive or perish, the road ahead is changing, but it can't resist their footsteps. Go on the march, heroes!
Li Hu jumped up from the ground all of a sudden, and lay in front of the computer again, he looked at the words that appeared on the screen, and then paused, and finally understood that this was the glory of the king.
Accidentally, Li Hu touched the keyboard. Immediately, another sentence appeared on the screen, displayed in a rectangular box in the center of the screen. Whether or not a player exits the game, there is a golden box that says "Confirm" and another light blue box that says "Cancel".
For a short time, I didn't even think about it. Li Hu clicked with the mouse to cancel, there is a game that is not played, is that a fool?
I saw that the screen instantly turned into the previous black screen, but at this time, it showed that the game was loading...... 68%, and at the bottom of the screen is a blue line that has already gone more than halfway.
Li Hu waited for a while, and finally waited for the last 99%. But only 1% of this load remains, and the time has passed so long.
Fifteen minutes have passed, 20 minutes have passed, and what is displayed on the screen is still 99%.
This is not obvious in the pit. Dad, the angry Li Hu really can't stand it. Originally, I wanted to play two games of kings, but looking at this situation, it is estimated that it will be loaded into next year.
Unable to bear the pain of waiting, Li Hu had to open the zipper and take out a box of Heilanzhou brand cigarettes from between his clothes.
Heilanzhou, as the name suggests, is one of many cigarettes. The market price is 18 yuan a box, and among the student group, there are very few people who can afford to smoke this kind of cigarette, and the so-called rare ones are about the same. Not all milk is called Trensu, and not all cigarettes are Heilanzhou. Not all people can afford to smoke in Heilanzhou.
When Li Hu just took out a cigarette from his cigarette case and was about to light it, the game finally appeared to be loaded. Immediately after that, another question popped up.
This question is described like this, please be sure to solve this question within 5 minutes, if the time is up, if you have not completed this question, not only the game of "Honor of Kings" will be uninstalled from now on, but even this computer will be permanently dead.
"Uninstall, crash?!" The cigarette in Li Hu's hand had already fallen to the ground, but he didn't know it, and he was still thinking about a chemistry problem that appeared on the screen.
If you can't complete it yourself, does it mean that Wang Xiang will never be able to come out from now on, then the QQ super member he owes me will disappear because of this.
can't be like this, not for Wang Xiang, but also for his QQ super member, Li Hu decided to solve this chemistry problem himself.
The chemistry problem shown on the computer screen is, please write the chemical equation (ion equation) involved in the principle of bromine and iodine extraction.
It took Li Hu less than half an hour to read the entire question, and the content mentioned in it is not exactly the required knowledge learned in Chemistry Compulsory 1?
"Oh no, Wang Xiang probably won't be able to get out now." Li Hu patted his head fiercely, he knew very well that the chemistry teacher had talked about this content, and he asked this question the next day. When he first spoke, Li Hu was already asleep in class, how could he know the extraction principle of bromine and iodine?
There's really no other way.,How can this game still have answers to questions?,It's really alive hell isn't it.。
Calming down, Li Hu took a closer look at the topic again. Chemical equations are not bracketed, while ion equations are bracketed, so in this case, chemical equations must be written, while ion equations can be written or not.
Knowing what to know, Li Hu can only take out his mobile phone now and try to search and learn.
He opened the Baidu interface and entered the keywords "Extraction Principle Equation of Bromine and Iodine", and then a detailed answer appeared on his phone.
Li Hu didn't panic, there were only 3 minutes left in the countdown, as long as the answer was entered, everything would not be a problem.
He was looking at the screen of his phone as he frantically tapped on the keyboard of his computer. It didn't take long for all the equations to pop up on the screen.
Cl2+2NaB
=2NaCl+B
2,Cl2+2B
-=2Cl-+B
2,Cl2+2KI=2KCl+I2,Cl2+2I-=2Cl-+I2,B
2+2KI=2KB
+I2,B
2+2I-=2B
-+I2。
After Li Hu finished writing, he did not rush to submit, but carefully rechecked it before and after, and made sure that all chemical equations were trimmed on both sides of the equal signs, and the charge numbers on both sides of the ion equation were conserved, and then he clicked submit.
You've beaten 16.7% of the players in the country, congratulations on completing the mission within the allotted time, and there's more to come, come on!
Although most of the evening self-study has passed, Cheng Biting Iron's thinking is still stuck in the evening self-study at the beginning.
Half a day has passed, and it is getting closer and closer to the task of finding a person with a high IQ in the three days stipulated by the Demon Star Spell. Cheng Biting Tie was in no mood to read at all, so he just grabbed his hair, "What should I do?" ”
