Answer:
Chemical Weathering is erosion of rocks and surfaces by chemical reactions. Otherwise, it is weathering the does not occur by mechanical processes, such as expanding ice, cracking rocks, from extreme heat, and etcetera. It occurs when chemical reactors come in contact with objects such as rocks. For example, when slightly acidic water reacts with rock minerals and forms clay, and salts, that would be considered Chemical Weathering.
