Let's analyze each property of copper listed to identify whether they are physical or chemical properties, and for physical properties, if they are intensive or extensive:

1. Reddish brown with luster:
- Physical or Chemical: This is a physical property because it describes the appearance of copper without altering its composition.
- Intensive or Extensive: This is an intensive property as it does not depend on the amount of copper present.

So the answer is:
| Property of Copper | Physical Property | Chemical Property | Intensive Property | Extensive Property |
|-----------------------------------|-------------------|-------------------|--------------------|--------------------|
| Reddish brown with luster | √ | | √ | |

2. Good conductor of heat and electricity:
- Physical or Chemical: This is a physical property as it pertains to the ability of copper to conduct heat and electricity without altering its chemical structure.
- Intensive or Extensive: This is an intensive property because conduction abilities do not change with the amount of material.

So the answer is:
| Property of Copper | Physical Property | Chemical Property | Intensive Property | Extensive Property |
|-----------------------------------|-------------------|-------------------|--------------------|--------------------|
| Good conductor of heat and electricity | √ | | √ | |

3. Will react with nitric acid:
- Physical or Chemical: This is a chemical property because it describes the reactivity of copper with another substance, altering its chemical composition.

So the answer is:
| Property of Copper | Physical Property | Chemical Property | Intensive Property | Extensive Property |
|-----------------------------------|-------------------|-------------------|--------------------|--------------------|
| Will react with nitric acid | | √ | | |

4. Can be melted and mixed with zinc:
- Physical or Chemical: This is a physical property because melting and mixing do not change the fundamental identity of copper.
- Intensive or Extensive: This is an extensive property because it depends on the amount of copper being melted and mixed.

So the answer is:
| Property of Copper | Physical Property | Chemical Property | Intensive Property | Extensive Property |
|-----------------------------------|-------------------|-------------------|--------------------|--------------------|
| Can be melted and mixed with zinc | √ | | | √ |

5. Density = 8.95 g/cm³:
- Physical or Chemical: This is a physical property as it describes a measurable characteristic of copper without changing its chemical composition.
- Intensive or Extensive: This is an intensive property because density is independent of the amount of material.

So the answer is:
| Property of Copper | Physical Property | Chemical Property | Intensive Property | Extensive Property |
|-----------------------------------|-------------------|-------------------|--------------------|--------------------|
| Density = 8.95 g/cm³ | √ | | √ | |

6. Will form a blue-green carbonate in moist air:
- Physical or Chemical: This is a chemical property because it describes a chemical reaction occurring when copper is exposed to moist air, resulting in a new compound (blue-green carbonate).

So the answer is:
| Property of Copper | Physical Property | Chemical Property | Intensive Property | Extensive Property |
|-----------------------------------|-------------------|-------------------|--------------------|--------------------|
| Will form a blue-green carbonate in moist air | | √ | | |
