Problem
Two different particulate diagrams each show clusters of atoms becoming closer together after a change.
• Diagram A: Individual H2O molecules, which were initially far apart, are now closely packed, but each molecule remains H2O.
• Diagram B: Separate H2 and O2 molecules disappear, and new triatomic molecules containing both element types appear closely packed.
Explain why the change in Diagram B is classified differently from the change in Diagram A, even though both diagrams depict particles becoming closer together.
