In the chemistry teaching and research room, Li Zheng, Lin Yujing, and Xu Mengxi were originally majestic and high-spirited, and they came to kill the topic with the momentum of thunder.

But as soon as I bumped into the first question, it was like falling into a gossip array-

[1. Write the chemical reaction equation according to the conditions]

[1-1: Industrially, ammonium bicarbonate and magnesium boronite (Mg2B2O4(OH)2) are used to prepare boric acid by reaction in aqueous solution]

Li Zheng: What the fuck is this? I'm really 150+ in chemistry?

Shen Mengxi: Don't panic...... Don't panic...... Analyze the ...... carefully Step by step...... Don't panic...... No...... Won't wow!

Lin Yujing: Hmm......>. <, refusing to recall.

The three of them let the wind go for a long time before they finally eased up a little and snuggled up to each other and returned to the chemistry department.

Pushing open the door, Sun Leyang and Yu Hong were sitting quietly without saying a word.

Why, even their judgment can't stand it?

When the three of them came to him, Sun Leyang shuddered, got up and glared at Lin Yujing.

"Lin Yujing, you are already the second in the province. ”

“？？？”

Sun Leyang excitedly picked up the test paper: "52 points! Do you know what the provincial line is? 55, 3 points short of saving one! Still haven't trained at all, you, you are going to enter the national team." ”
