which is a chemical property of aluminum

a- melting point is 660c

b- boiling point is 2519c

c- does not dissolve in water

d- reacts with oxygen

My answer is D

d is the only chemical reaction implied so I agree with you.

Your answer is correct. The chemical property of aluminum that is described in choice D is that it reacts with oxygen. To determine the correct answer, you can eliminate choices A and B because they refer to physical properties (melting point and boiling point) rather than chemical properties. Choice C, "does not dissolve in water," is a physical property as well. Remaining choice D, "reacts with oxygen," is a chemical property since it describes how aluminum molecules interact with oxygen molecules to form aluminum oxide through a chemical reaction. Well done!
