Explanation:

Step1: Recall definitions

Homogeneous matter has uniform composition, heterogeneous has non - uniform. Pure substances are elements or compounds, mixtures are combinations of substances.

Step2: Classify homogeneous/heterogeneous

1. Carbonated soft drink (w/bubbles): Heterogeneous (bubbles are distinct phases).
2. Chocolate chip ice cream: Heterogeneous (chocolate chips are distinct).
3. Italian salad dressing: Heterogeneous (oils, herbs etc. separate).
4. Corn syrup: Homogeneous (uniform composition).
5. Soil: Heterogeneous (contains various particles).
6. Aluminum foil: Homogeneous (pure aluminum).
7. Black coffee: Homogeneous (uniform mixture).
8. Sugar water: Homogeneous (sugar dissolved uniformly).
9. Air (with smog): Heterogeneous (smog particles are distinct).
10. Paint: Homogeneous (uniform mixture).
11. Rubbing alcohol: Homogeneous (uniform mixture).
12. Full - fat milk: Heterogeneous (fat globules in water).
13. Beach sand: Heterogeneous (various minerals and particles).
14. Pure air: Homogeneous (uniform gas mixture).
15. Chunky spaghetti sauce: Heterogeneous (chunks are distinct).

Step3: Classify pure substances/mixtures

1. Sodium (Na): Pure substance (element).
2. Water (H₂O): Pure substance (compound).
3. Soil: Mixture (various substances).
4. Coffee: Mixture (various compounds in water).
5. Oxygen (O): Pure substance (element).
6. Isopropyl alcohol dissolved in water: Mixture.
7. Carbon dioxide (CO₂): Pure substance (compound).
8. Cake batter: Mixture (flour, eggs etc.).
9. Air: Mixture (nitrogen, oxygen etc.).
10. Chicken noodle soup: Mixture (noodles, broth etc.).
11. Iron (Fe): Pure substance (element).
12. Salt water: Mixture (salt and water).
13. Chocolate chip ice cream: Mixture.
14. Nitrogen (N): Pure substance (element).
15. Eggs: Mixture (yolk, white etc.).
16. Blood: Mixture (cells in plasma).
17. Table salt (NaCl): Pure substance (compound).
18. Nail polish: Mixture (solvents, polymers etc.).
19. Milk: Mixture (fat, proteins etc. in water).
20. Soda: Mixture (carbon dioxide, sugars etc. in water).
