ykJ heat. The thermochemical equation for the reaction between CO and NaOH solution to produce NaHCO is ()

He raised his eyelids slightly and looked at the chemistry teacher and said, "If I make it, you won't trouble me anymore?"

Sun Xi hummed: "I am a teacher, I do what I say!

"good!"

Yang Tian nodded, then picked up the pen and wrote a series of formulas on the paper.

The handwriting is so flying that it almost breaks out of the paper!

CO(g)+NaOH(aq)===NaHCO(aq); △H=-(4-y)kJ·mol-1

After finishing the last stroke, he put the carbon pen on the hard wooden table and turned around to leave.

Clean, neat and chic!

Sun Xi's jaw almost dropped, and her beautiful eyes were wide and round.

Yes, he did it right!

This is impossible, this is unscientific, and this is not consistent with common sense. He should not be able to do this question.

Sun Xi asked loudly: "Yang Tian, ​​how did you do this question right?"

Yang Tian stopped at the door, and a clear voice passed into Sun Xi's ears.

"Damned!"

"Ahhh!" Sun Xi was so angry that she rubbed her hair into a mess. You can fool the multiple-choice questions, but how can you fool the fill-in-the-blank questions? She thought she was mentally retarded.

She shouted sweetly: "Yang Tian, ​​stop here, I have another question to answer, please come back and hide it once."

By this time, Yang Tian had already returned to the classroom.

Never believe what a woman says, especially a beautiful woman!

-------

Back in the classroom, Yang Tian felt that everyone was looking at him strangely.

The bespectacled man, the chemistry class representative, was definitely on the front line. He sarcastically said: "How about Yang University Bully? Did you get a lesson from the chemistry teacher?"

Yang Tian smiled and said nothing.

The other party may have said the wrong thing, and it was not Sun Xi who taught him a lesson.

Instead, he taught Sun Xi a lesson.

Now Sun Xi should be doubting life in the office.

Seeing that Yang Tian was silent, the man with glasses became more convinced of his own thoughts.

So, this time he became Benjili, walked up to Yang Tian, ​​pointed at Yang Tian with slanderous words again, and said with disdain: "Yang Tian, ​​I tell you, you stole the show in math class and Chinese class, but in

Chemistry class, that is my world, don’t think you..."
