Two samples of solids have similar reactivity with acids and similar densities. Their masses volumes, however are not at all similar. Is it possible that these are the sane substance?

Question

A. No, it is not possible because they have different extensive properties
B. No, it is not possible because they have different intensive properties.
C. Yes, it is possible because they have similar intensive properties
D. Yes, it is possible because they have similar extensive properties

Answer 1

The correct answer is:

A. No, it is not possible because they have different extensive properties.

Extensive properties, such as mass and volume, depend on the amount of substance present. Since the two samples have different masses and volumes, they must be different substances. Even if they share similar reactivity with acids and similar densities (which are intensive properties), the differences in extensive properties indicate they are not the same substance.
