Question

Give the example for chemical reaction in chemical weathering

Answer 1

Carbonation is another type ofchemical weathering. Carbonation is the mixing of water with carbon dioxide to make carbonic acid. This type of weathering is important in the formation of caves. Dissolved carbon dioxide in rainwater or in moist air forms carbonic acid, and this acid reacts with minerals in rocks.

Answer 2

Answer:

Hydration is a type of chemical weathering where water reacts chemically with the rock, modifying its chemical structure. One example of mineral hydration is when H2O (water) is added to CaSO4 (calcium sulfate) to create CaSO4+2H2O (calcium sulfate dihydrate). It changes from anhydrite to gypsum
