Step-by-step explanation:
Looking at the atom, you see that there is 1 carbon atom and 2 oxygen atoms.
The chemical formula of Carbon is just C (from the periodic table), and the chemical formula of Oxygen is just O (from the periodic table).
When you create the chemical formula of a compound, you want to indicate how many atoms of each element there are. Here, since there are 2 oxygen atoms, you want to have some form of
, and since there's only 1 carbon atom, you want to have some form of C.
Now, we just put it together:
