Why are both oxygen and moisture considered necessary for rusting of iron?
Answer and explanation
Correct answer: Iron reacts with oxygen and moisture helps the process
Rusting is a slow electrochemical oxidation of iron. Iron loses electrons while oxygen is reduced, and a thin water layer allows ions to move between the reacting regions. In ordinary conditions, removing either oxygen or moisture greatly prevents or slows rust formation. Thus option A gives the correct roles. The other choices incorrectly describe melting, gas formation, blocking, or inactivity.
