Answer 1

The best term that describes "copper compounds are green when burning" is a chemical property.

This is because the green color observed when copper compounds are burned is related to the chemical behavior of the compounds during combustion, particularly their ability to emit specific wavelengths of light due to electron transitions. This characteristic indicates a change in the chemical composition or state, making it a chemical property rather than just a physical aspect.
