Chapter 245 280 Chemistry Problems

There is still a week before the Spring Festival, after finishing handling the company's affairs every day, when Lin Ming returns to Jiang Chen Yipin's home, he will make video calls with Shangguan Shiyue at night.

Xie Qianlin's home is not in Jinghua City, so she went back early.

There are only Lin Ming and Ye Bingning in Jiang Chen's family.

Although it was winter vacation, Ye Bingning, who had already entered the third year of high school and was about to take the college entrance examination, could not relax at all.

Even during the holidays, she still insisted on getting up at six o'clock in the morning and studying until ten o'clock in the evening.

On the desk in Ye Bingning's room, there is a work and rest timetable. The schedule in the form is full, and everything is planned from what time to what time to study.

In the one-month winter vacation, according to the table, there are only four days of rest.

Because Ye Bingning is an orphan like Lin Ming, there is no need to visit relatives at all.It is enough to set aside a day to reunite with classmates.

For Lin Ming, Ye Bingning is the only one who can be regarded as a relative.

Lin Ming's middle school life was spent working part-time, so he didn't have any particularly good friends. For him, even class reunions were omitted.

Qin Lili and her family have already gone to Australia for vacation. Every day, she will send out photos in swimsuits, showing off her figure. It is winter in Jinghua City, but it is hot summer in Australia.

——I can’t even wear last year’s swimsuit. Is it true that I’m still developing?

Qin Lili captioned a photo of herself, in which Qin Lili is wearing an aqua blue bikini, sitting on a sun-drenched beach, wearing a pair of colorful lotos folding sunglasses, facing the camera Smile.

Next to her was a glass of orange juice, half of which had been drunk.

Lin Ming looked at the photo, took his mobile phone and replied below, "It's just that the quality of the swimsuit has shrunk, don't think too much about it."

"You just shrunk. This is Charmline's swimsuit, how could it shrink!" Qin Lili immediately replied.

Seeing Qin Lili's message, Lin Ming picked up the phone and planned to continue teasing Qin Lili, but just as Lin Ming pressed a letter, the phone was snatched away.

"Brother! Don't play with your phone, teach me chemistry." Ye Bingning held Lin Ming's phone behind her back.

"Let's talk about it in the evening. Let me rest in the afternoon." Lin Ming lay on the sofa.

"No! If you don't teach me how to do the questions, I won't cook for you at night." Ye Bingning looked at Lin Ming dissatisfied.

"Then what do you eat?"

"I... I eat takeaway."

"I also eat takeaway."

"elder brother!"

"Okay, I'll just teach you." Lin Ming had no choice but to get up, and followed Ye Bingning into her bedroom.

Ye Bingning took out the exercise set and pointed to a question:
Which of the following statements is correct
A silicon material is widely used in optical fiber communication
B craftsmen use hydrochloric acid to etch quartz to make artwork

C The crystal necklace and the porcelain plate on the dining table are made of silicate
D The preparation of single crystal silicon from crude silicon does not involve redox reactions
Lin Ming stared at the title for a while, "In B, hydrofluoric acid is used to etch quartz, in C, the crystal component is silicon dioxide, in D, the reaction of crude silicon with chlorine gas and then reduced to silicon is a redox reaction. The last three are Wrong, so the answer is A."

"But, but why can't I choose? I have no idea?"

"Although chemistry is a science, it is actually a liberal arts. You need to memorize some basic things. It is not like mathematical physics. You can solve all the problems by memorizing a few formulas, so don't be lazy. You must memorize all the things that need to be memorized." " Lin Ming poked Ye Bingning's forehead with his fingertips as he spoke.

"Eh... I learned science because I was too lazy to memorize, so I still have to memorize." Ye Bingning pouted and rubbed her forehead.

ps: Do you think Shangguan Shiyue should change her surname? If so, what do you think is better?It’s best to have a reason, such as changing her surname to Liu because her mother’s surname is Liu, changing her surname to Li because she thinks she is a princess of the Tang Dynasty, changing her surname to Lin because Lin Ming saved her, or changing her surname to something else sounds better. . .Please give your opinion.
