Question

classify each of the following properties as chemical or physical: acidity, combustibility, viscosity. use the references to access important values if needed for this question

Explanation:

Acidity is a chemical property as it involves chemical reactions and changes in substances at a molecular level. Combustibility is also a chemical property since it describes how a substance reacts with oxygen to produce heat and light during combustion. Viscosity is a physical property as it is a measure of a fluid's resistance to flow and can be observed and measured without changing the substance's chemical composition.

Answer:

Acidity: Chemical
Combustibility: Chemical
Viscosity: Physical
