Answer 1

A. Acids act as a corrosive to metal

B. Gold has a density of 19.3 g/cm3

C. Hydrochloric Acid reacts with Zinc metal, creating hydrogen gas

D. Hydrochloric Acid reacts with Zinc metal, creating hydrogen gas

B would be the correct answer. A, C, and D all describe chemical changes occurring to materials (corrosion involves acid-base reactions typically). We know that density is a physical property thus making B the correct choice.
