1. state of matter
2. the rough feel of

sand paper

1. can neutralize a base
2. the sweet smell of

a rose

1. volume
2. the density of water

Explanation:

To solve this, we recall:

• Physical properties: Observable/measurable without changing the substance’s chemical identity (e.g., color, density, mass, state, texture, smell, volume).
• Chemical properties: Describe how a substance reacts with others (e.g., flammability, reactivity with acid/base/water, neutralization, combustibility).

1. Red color

Step: Color is observable without chemical change.
→ Physical Property

2. Density

Step: Density is measured without altering the substance.
→ Physical Property

3. Flammability

Step: Flammability describes combustion (a chemical reaction).
→ Chemical Property

4. Mass

Step: Mass is measured without chemical change.
→ Physical Property

5. Reacts with acid to form hydrogen

Step: Reaction with acid is a chemical change.
→ Chemical Property

6. Combustibility

Step: Combustibility involves burning (chemical reaction).
→ Chemical Property

7. Sour taste

Step: Taste is observable without chemical change.
→ Physical Property

8. Reacts with water to form a gas

Step: Reaction with water is a chemical change.
→ Chemical Property

9. Reacts with a base to form water

Step: Reaction with a base is a chemical change.
→ Chemical Property

10. State of matter

Step: State (solid/liquid/gas) is observable without chemical change.
→ Physical Property

11. The rough feel of sandpaper

Step: Texture is observable without chemical change.
→ Physical Property

12. Can neutralize a base

Step: Neutralization is a chemical reaction.
→ Chemical Property

13. The sweet smell of a rose

Step: Smell is observable without chemical change.
→ Physical Property

14. Volume

Step: Volume is measured without chemical change.
→ Physical Property

15. The density of water

Step: Density is measured without altering water’s identity.
→ Physical Property
