Natural reactions in water and air

The following simulation represents an interface between the air and the ocean. If a guide appears, you can click on ‘skip’. Leave the cursor on ‘sequential’ mode.

You will be able to click several times on the Play buttons to see the chemical reactions that take place naturally between air and water and in ocean water. On a piece of paper in front of you, draw all the reactions you see (this can be as on the screen, with coloured balls, or in Lewis notation if you are more advanced in chemistry).

Don't click on the ‘Chemical equations’ button just yet (you will later), but try to work out what's going on with your current chemistry skills.
