Q. Assertion :Rusting of iron is considered an oxidation reaction. Reason: Rust is another name for iron oxide which occurs when iron is exposed to oxygen and moisture for a long period of time. Overtime the oxygen combines with the metal at atomic level forming a compound called an oxide. Rust forms when iron undergoes oxidation. The main catalyst for the rusting process is water.

Q. Consider the following statements.

A - Iron + Moisture + Oxygen = Iron Oxide.

B - The rust that develops in rocks with iron content cannot be removed, thereby, keeping the original structure of the rock intact.
