Hi, Haromi and Manami.
You looks busy.
What's up?
We have to learn a lot of chemical reaction formulas.
We have studied science for two hours.
I have been busy about this since yesterday.
What is 2H2O?
Teach me it, Sukuo.
OK.
You know that water consists of hydrogen and oxygen.
The chemical formula for water is H2O.
Hydrogen has two atoms.
Oxygen also has two atoms.
That's right.
One oxygen atom is left when they add.
So one oxygen atom add two hydrogen atoms.
And they become two H2O.
2H2 plus O2 is 2H2O.
I have not thought such a thing.
This field is very difficult.
Have you studied it for a long time?
Yes, we have.
I will not be able to sleep this night.
I slept only little yesterday.
How long have you slept?
About for three hours.
You should sleep to learn the difficult formulas. |
