Two samples of solids have varied reactivity with bases and have different densities. There masses and volumes, are similar. How could you support that these are in fact different substances? (1 point)
A.They are the same because they have similar intensive properties.
B. The differing densities and reactivities support that they are not the same substance.
C. They are the same because they have similar extensive properties.
D.The similarities of their masses suggest they are the same substance.
