In Chemistry, we have chemical reaction. I heard the part on Lalla, you were saying future what to be? 

We are using in the biology, so chemistry, is free zone?

Molecule, compound, reaction, dissociation/ precipitation, say equilibrium reach. Double arrow.

You cannot possible first forward reaction going that way, and return immediately. It takes at least a second and back? So there is 2 arrows sequence.

I didn't hear anything on chemistry ....de...okay, they exist too. 

Just about the same.

Chinese using Chinese words in Biology? My tapes must be useful!
