Answer 1

In each molecule of adrenaline, there is 3 molecules of oxygen atoms.

Answer 2

Carlos’s model represents the different atoms, and recognizes that they are separate particles. I chose his model because he doesn’t connect them and make it look as if they may be the same model. On the other hand Javier’s model is more in depth in the explaining of a molecule, it doesn’t illustrate the difference between the particles.
