What are the properties of the aluminum in the can? Check all that apply.

Aluminum conducts electricity and is solid at room temperature, so A and B apply. It does not react easily with air or water because a thin protective oxide layer forms on its surface, so D applies. Aluminum is malleable rather than brittle, and its density is about 2.7 g/cm³—greater than water’s—so C and E do not apply.
