Chapter Ninety-Six: Sixty-Four Pieces of Sugar

Wei Man was excited, Bai Song didn't want it, he could eat one more pack, so he smiled at Bai Song, and wanted to take the pack of spicy strips back to you, who knows, there is a hand that is faster than hers, and just when she wanted to take it, she was taken away by a fair-skinned and slender hand.

Wei Man didn't have to think about who it was, except for Qu Anyi, who would be so boring, so he rolled his eyes, stuck his waist, and looked angrily at Qu Anyi, who had already sat back in his seat.

"Give me back the spicy strips!" Wei Man opened his teeth and claws to grab the bag of spicy strips that had been torn open by him.

Qu Anyi took one out and put it in his mouth, and before he could chew it, Wei Man slapped a shadowless palm on his face, and in the next moment, she snatched the spicy strips in his hand.

"Stinky and shameless!" Wei Man glared at him in disgust, then turned around and ate the spicy strips in his stomach.

was stunned Qu Anyi, who am I? Where am I? What am I doing?

Bai Song ignored what happened to the two people, and concentrated on reading books and doing questions. Once she gets serious, she will automatically block the disturbances next to her and enter her own small circle.

How to solve this problem?

17.4gMnO2 solid powder is coheated with a certain volume of concentrated hydrochloric acid (containing 0.4mol of solute) to prepare chlorine gas (assuming HCl volatilization loss is not counted), which of the following statements is correct?

Bai Song looked at the options, and was a little unsure which one to choose, so he opened the book, looked at the knowledge points in the book, and practiced on the sketchbook.

"Pick C." I don't know when there was an extra voice next to him, Bai Song looked up suspiciously, and faced Xu Yihuai, who was sitting in front of him.

"Huh?" Bai Song was slightly surprised and looked at him.

"Options A and B are deceptive, and as the reaction progresses, the concentration of hydrochloric acid decreases, and the corresponding reduction decreases." Xu Yihuai's slender fingertips pointed to Bai Song's workbook spread out on the table, and his voice was slow and low, "Until the redox reaction that occurs is stopped, so in this reaction process, although MnO2 is excessive, hydrochloric acid cannot completely react, and similarly, the collected gas cannot be 2.24L." But in any case, half of the hydrochloric acid involved in the reaction must be oxidized. ”

"That's why the answer is C." Xu Yihuai put away his hand, looked at Bai Song, who was still a little stunned, and frowned a little, he told her so seriously, she was actually in a daze?

"Do you understand?" Xu Yihuai frowned, and there was still a trace of resentment in his tone.

Bai Song reacted at this time, and quickly nodded a few times, indicating that he understood.

"Then tell me about it." Xu Yihuai leaned back slightly and said leisurely.

“.........”

"Forehead......" Bai Song was a little embarrassed, just now he was busy wondering how he could give himself a lecture, although the latter was understood, but at the beginning he didn't listen carefully at all.

"You ....." Xu Yihuai just wanted to say something, but the bell of the last night's self-study broke what he wanted to say.

Xu Yihuai had no choice but to get up, walked back to his seat, and didn't say anything. Bai Song lowered his head and bit his lip. Fill in the answer given by Xu Yihuai. Forget it, there is an answer anyway, and it won't be long before you take a closer look at the answer? What's more, there may not be this question in tomorrow's exam.

Bai Song suppressed the disturbances in his mind, and then saw his front table looking at her with a look of surprise.

"Hey, Liu Xue. What are you looking at me for? Bai Song looked at Liu Xue's eyes at the front table and said suspiciously.

"Who's looking at you, I'm obviously looking at Huaishen." Liu Xue, who was still a nymphomaniac, looked obsessed and said, "I saw it at the door just now, Huaishen sat in my seat, do you think I should move this stool home and hide it?" ”

"Hm...."Bai Song tugged at the corners of his mouth, not going to pay attention to her.

Forget it, they may all become "crazy" when they see Xu Yihuai.

Bai Song forgot that he was one of these tens of millions of "crazy people" before........

After the comprehensive is over, it means that the monthly exam in September is really over. Bai Song returned to the classroom, sat back in his seat, and couldn't help but stretch.

There are other students in the classroom, and they will come back to answer as soon as the exam is over, Bai Song is too lazy to join in the fun, anyway, the exam is over, and it is not the college entrance examination, so there is no need to make yourself so nervous.

"I'm leaving, Xiaobai." Wei Man was going back to dinner, waved to Bai Song, and said.

Bai Song said yes, and then saw Wei Man leave through the back door.

Xu Yihuai hasn't come back yet, Bai Song decided to wait for him here, the two of them have been walking together to and from school in the past few days, so Bai Song is afraid that Xu Yihuai will wait for her here for a long time after he leaves.

The people who were still in the classroom to answer the answer just now also left, presumably to dinner. Bai Song took out his mobile phone in his bookbag and glanced at the time, it was almost half past five.

Where did Xu Yihuai go?

Bai Song pressed the screen and found his phone number, but he didn't know if he had brought his mobile phone.

Although Bai Song thought so, he still pressed the dial to build.

"Beep-" The phone rang three seconds before it was connected.

"Xu Yihuai? Where are you? Before the other party could answer first, Bai Song asked straight to the point.

The other side paused for a few seconds before speaking, "You don't have to wait for me first, I have something to do with An Yi." ”

Bai Song nodded, realizing that he was on the phone, and he couldn't see her movements on the other side, so Bai Song said a good word. Then he hung up the phone, Bai Song walked out with a cartoon bookbag on his right shoulder.

Bai Song returned home, opened the door and saw his father sitting on the sofa, Bai Song shouted happily, excited and with a trace of doubt.

"Why did Dad think he would come to see me today?" Bai Song hugged Father Bai's neck and asked arrogantly.

"This kid, doesn't Dad miss my baby daughter?" Father Bai patted Bai Song's shoulder and said.

"Really? That's once in a long time. After all, it was not your own. Bai Song pouted and subconsciously said this.

Father Bai and Aunt Xiaoyun, who was sitting on the side, glanced at each other, and the panic in their eyes flashed.

"How can you say such a thing? Of course you were born to me and your mother. Father Bai was a little angry and frowned.

Bai Song saw that his father was about to show some signs of anger, and hurriedly coaxed, "I know, I don't just say it, I see that you are still serious." ”

"You can't just talk about it." Father Bai opened his mouth without thinking about it.

Bai Song saw that Father Bai was really angry, and hurriedly showed goodwill, "Yes, yes, I know." ”

She was afraid that if she continued to argue, her father would tell her a lot of reasoning again.

"Oh, Xiao Song just finished the exam, just joking to relieve the pressure, Lao Bai, you are still serious." Aunt Xiaoyun, who was sitting on the side, hurriedly said.

Father Bai's complexion improved a little now, and he said in a kind tone, "Let's go and have dinner." ”

Bai Song nodded, saw that so many delicious foods were made on the table, and said to Father Bai and Aunt Xiaoyun, "Auntie, Dad, you guys come and eat too, Xu Yihuai has something to do, and he won't come back to eat." ”

"Daddy's coming home." Father Bai stood up as he spoke, looked at Bai Song and said.

"So fast?" Bai Song was slightly surprised.

"yes, I'm walking after dinner." Aunt Xiaoyun also stood up and said to Father Bai.

Father Bai waved his hand and said to Bai Song, "Don't make trouble for your aunt here, be obedient." ”

Bai Song nodded.

"Xiao Song is very well-behaved and sensible, how can he cause trouble for me." Aunt Xiaoyun said with a smile.

Father Bai laughed heartily a few times, then patted Bai Song's shoulder, waved his hand to Aunt Xiaoyun, opened the door and went out. Take a hundred plating on the latest chapter of "You Are My Little Liangchen Claw Book House" to read for free for the first time.
