The sodium, hydrogen, and oxygen cannot be made into simpler substances, but the carbon dioxide can be made into two simpler substances. Identify each of the chemicals involved (baking soda, sodium, hydrogen, oxygen, and carbon dioxide) as compounds or elements.

Answer 1

Here’s the classification of each of the chemicals involved:

1. Sodium (Na) - Element
2. Hydrogen (H) - Element
3. Oxygen (O) - Element
4. Carbon Dioxide (CO₂) - Compound
5. Baking Soda (Sodium Bicarbonate, NaHCO₃) - Compound

In summary, sodium, hydrogen, and oxygen are elements, while carbon dioxide and baking soda are compounds.
