The correct statement that explains the difference in mass when iron rusts and forms iron oxide is:
**Iron oxide has oxygen atoms, and pure iron does not.**
When iron rusts, it reacts with oxygen from the environment to form iron oxide (rust). The addition of oxygen atoms increases the total mass of the resulting compound compared to the pure iron that was present before rusting.
