This leaves only one answer, however we can also find the answer by observing what chemical weathing is.

anonymous · Answer

Chemical weathering is the weakening and subsequent disintegration of rock by chemical reactions. These reactions include oxidation, hydrolysis, and carbonation. These processes either form or destroy minerals, thus altering the nature of the rock's mineral composition.
