Here's the table with the substances correctly marked as elements or compounds:

| Substance | Classification | |------------------------|----------------| | Iron (Fe) | Element | | Sodium Chloride (NaCl) | Compound | | Carbon dioxide (CO2) | Compound | | Aluminum (Al) | Element |

Therefore, the two substances that are compounds are Sodium Chloride (NaCl) and Carbon dioxide (CO2), while Iron (Fe) and Aluminum (Al) are the elements.
