Explanation:

Step1: Identify atoms

In chemistry, different letters represent different atoms. Here, 'O' represents oxygen, 'C' represents carbon, 'H' represents hydrogen, and 'N' represents nitrogen.

Step2: Write chemical formulas

a. There are 3 oxygen - carbon - oxygen combinations. The formula is $CO_2$ (assuming double - bonds between carbon and oxygen and 2 oxygen atoms bonded to 1 carbon atom in a common structure).
b. There are 2 carbon atoms and 6 hydrogen atoms. The formula is $C_2H_6$.
d. There are 6 nitrogen atoms. The formula is $N_6$.
e. There are 8 hydrogen atoms. The formula is $H_8$.

Answer:

a. $CO_2$
b. $C_2H_6$
d. $N_6$
e. $H_8$
