The product of the reaction will be [tex]2CO_2[/tex]. The complete reaction will be written as:
[tex]2CO+O_2 \rightarrow 2CO_2[/tex]
where on the left we have carbon monoxide and molecular oxygen, and on the right we have carbon dioxide. We see that the total count of the atoms works: on the left, we have 2 atoms of carbon C as well as on the right; similarly, on the left we have 2+2=4 atoms of oxygen, and on the right as well.
