Answer 1

Copper slowly forming a blue-green carbonate in moist air is a chemical property.

Step-by-step explanation:

Copper slowly forms a blue-green carbonate in moist air is a chemical property rather than a physical property. Chemical properties describe the characteristic ability of a substance to react to form new substances. In this case, copper reacting with air to form a carbonate is a chemical change, indicating a chemical property.
