Answer 1

The agent of chemical weathering among the options provided is **acid rain**. Acid rain can chemically react with minerals and rocks, leading to their breakdown. The other options, such as iron, copper patina, and iron oxide, are not agents of chemical weathering themselves but can be products or results of the weathering process.
