Final answer:
Carbon Dioxide, Baking Soda, and Table Salt are identified as compounds as they are made of two or more elements chemically combined. Iron, Copper, Oxygen are elements, not compounds. Bleach and Juice are mixtures.
Step-by-step explanation:
In identifying pure substances that are compounds from the given list, we must distinguish between elements, compounds, and mixtures. Compounds are substances that are made up of two or more different elements that are chemically combined in fixed proportions. Based on this definition, we can mark the pure substances that are compounds as:
- Carbon Dioxide (CO₂) - A compound made of carbon and oxygen.
- Baking Soda (sodium bicarbonate, NaHCO₃) - A compound consisting of sodium, hydrogen, carbon, and oxygen.
- Table Salt (sodium chloride, NaCl) - A compound composed of sodium and chlorine.
The other substances listed such as Bleach (a mixture, typically a solution), Iron (an element), Copper (an element), Oxygen (an element), and Juice (a heterogeneous mixture) are not compounds. While bleach may contain compounds such as sodium hypochlorite, it is still a mixture and not a pure compound.
