two samples of solids have similar reactivity with acids and similar densities. their masses and volumes, however, are not at all similar. is it possible that these are the same substance?

Respuesta :

Given that the volume and mass of a substance are not defining properties, it is entirely possible for two samples with different volumes and mass to be the same substance.

What are defining properties of a substance?

  • These are properties that can help us to identify a substance.
  • The most useful of which tend to be chemical properties such as reactiveness or melting points.
  • Colors and density can also offer the insight needed to identify elements and substances.
  • Mass and volume are not properties of a substance given that they can change often depending on the sample size and thus do not help to identify a substance.

Therefore, since the volume and mass of a substance are not defining properties of a substance, we can confirm that it is entirely possible for two samples with different volumes and mass to be the same substance.
