physical property\tchemical property

Explanation:

Step1: Recall physical and chemical property definitions

Physical properties can be observed or measured without changing the substance's chemical identity. Chemical properties are observed when a substance undergoes a chemical change.

Step2: Categorize each property

1. Blue color - Physical property (Observed without chemical change)
2. Density - Physical property (Measured without chemical change)
3. Flammability - Chemical property (Involves burning - a chemical change)
4. Solubility - Physical property (Substance dissolves, no new substance formed)
5. Reacts with acid to form H₂ - Chemical property (New substance hydrogen is formed)
6. Supports combustion - Chemical property (Involves chemical reaction of burning)
7. Sour taste - Physical property (Observed without chemical change)
8. Melting point - Physical property (Change of state, no chemical change)
9. Reacts with water to form a gas - Chemical property (New gas formed)
10. Reacts with a base to form water - Chemical property (Chemical reaction occurs)
11. Hardness - Physical property (Measured without chemical change)
12. Boiling point - Physical property (Change of state, no chemical change)
13. Can neutralize a base - Chemical property (Chemical reaction of neutralization)
14. Luster (shiny) - Physical property (Observed without chemical change)
15. Odor - Physical property (Observed without chemical change)
