Among the options listed, **acid rain** is an agent of chemical weathering. Acid rain can lead to the breakdown of minerals and rocks through chemical reactions, particularly by increasing the acidity of precipitation and promoting the alteration of minerals.
The other options—copper patina, iron, and iron oxide—are products or forms of materials that can be involved in weathering processes, but they are not agents of chemical weathering themselves.
