A. $N a O$ $NaO$
B. $C_{4} H_{3} O_{2}$ $C_4H_3O_2$
C. $C_{12} H_{12} N_{2} O_{3}$ $C_12H_12N_2O_3$
D. $C_{2} H_{3} C l$ $C_2H_3Cl$

Explanation:

An empirical formula is the lowest ratio of the elements in a compound.

So for each of the compounds above, the GCF of the elements was used to divide the number of the atoms of each element in the formulas of the compounds.
