4. coffee
5. oxygen pure substance
6. isopropyl alcohol
7. carbon dioxide
8. cake batter
9. air
10. chicken noodle soup
11. iron pure substance
12. salt water
13. chocolate chip ice cream
14. nitrogen pure substance
15. eggs
16. blood
17. table salt pure substance
18. nail polish
19. milk
20. soda

Explanation:

A homogeneous mixture has a uniform composition throughout, while a heterogeneous mixture has a non - uniform composition. A pure substance is either an element or a compound, and a mixture is made up of two or more substances physically combined.

1. Carbonated soft drink with bubbles: Heterogeneous (due to visible bubbles).
2. Chocolate chip ice cream: Heterogeneous (chocolate chips are distinct).
3. Italian salad dressing: Heterogeneous (components separate over time).
4. Corn syrup: Homogeneous (uniform composition).
5. Soil: Heterogeneous (contains various particles and components).
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 dispersed non - uniformly).
10. Paint: Homogeneous (when well - mixed).
11. Rubbing alcohol: Homogeneous (usually a solution).
12. Full fat milk: Heterogeneous (fat globules dispersed).
13. Beach sand: Heterogeneous (various sized particles and minerals).
14. Pure air: Homogeneous (uniform gas mixture).
15. Chunky spaghetti sauce: Heterogeneous (chunks are visible).

For pure substances vs mixtures:

1. Sodium: Pure substance (element).
2. Water: Pure substance (compound).
3. Soil: Mixture.
4. Coffee: Mixture.
5. Oxygen: Pure substance (element).
6. Isopropyl alcohol: Pure substance (compound).
7. Carbon dioxide: Pure substance (compound).
8. Cake batter: Mixture.
9. Air: Mixture.
10. Chicken noodle soup: Mixture.
11. Salt water: Mixture.
12. Chocolate chip ice cream: Mixture.
13. Eggs: Mixture.
14. Blood: Mixture.
15. Nail polish: Mixture.
16. Milk: Mixture.
17. Soda: Mixture.
