For the phases of each compound, we have to put the appropriate symbol below as a subscript of the formula of the compound:

solid - (s)
liquid - (l)
gas - (g)
aqueous - (aq)

PART A

First, we take note of the list below for compounds that should be diatomic. 

H N F O I Cl Br

Oxygen (O) belongs to this list so we know its diatomic.
