select all the ways in which two substances can be different. two substances can be composed of molecules that contain the same chemical elements but have different numbers of atoms of each element. two substances can be composed of different chemical elements. two substances can be composed of the same chemical elements, but the substances can have crystal structures with atoms that are arranged differently.

select all the ways in which two substances can be different. two substances can be composed of molecules that contain the same chemical elements but have different numbers of atoms of each element. two substances can be composed of different chemical elements. two substances can be composed of the same chemical elements, but the substances can have crystal structures with atoms that are arranged differently.

Answer

Brief Explanations:

  1. Different atom - counts of same elements create different substances (e.g., CO and CO₂).
  2. Different chemical elements result in different substances (e.g., H₂O and O₂).
  3. Different atomic arrangements in crystal structures of same - element substances make them different (e.g., diamond and graphite).

Answer:

  • Two substances can be composed of molecules that contain the same chemical elements but have different numbers of atoms of each element.
  • Two substances can be composed of different chemical elements.
  • Two substances can be composed of the same chemical elements, but the substances can have crystal structures with atoms that are arranged differently.
