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

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

Answer

Brief Explanations:

  1. Different crystal - structures of the same elements make substances different, like diamond and graphite (both carbon but different structures).
  2. Different chemical elements result in different substances, e.g., oxygen and nitrogen.
  3. Molecules with same elements but different atom - counts are different substances, such as ethanol ($C_2H_5OH$) and dimethyl ether ($CH_3OCH_3$).

Answer:

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