Rainwater is naturally slightly acidic. The acid in rainwater reacts chemically with the calcium carbonate of limestone, dissolving it. The result is chemically weathered limestone, karst terrains, and cave structures.
The most common chemical sedimentary rock is limestone.
The primary agent of chemical weathering is water.
Chemical weathering is acid rain. If it rains onto carbonate rocks e.g. limestone, they undergo a chemical reaction. This breaks down the rock.Biological weathering is animals and plants. Rabbits burrow under rocks which weakens them. Tree roots grow through rocks and weaken them. Weak rock breaks up easily.Hope this helps x
Limestone is chemically reactive with acids, and due to naturally acidic rain and acids picked up from the soil in groundwater, it is more susceptible than other common rocks to chemical weathering
Quartz goes through virtually no chemical weathering, as its form SiO2 is extremely stable. It's nearly unreactive.
The most common cause of chemical weathering is oxygen

Acid does indeed cause weathering. It is a common form of chemical weathering, and is sometimes influenced by humans. It is particularly devastating to basic rocks like limestone which neutralise the acid rain, but at the expense of its own volume, as after the neutralisation, the salt is often washed away and the limestone is consequently worn away.
Chemical weathering is most common in warm and wet climate.

What mechanical and chemical weathering have in common is they both break rocks down into smaller and smaller pieces. Eventually the weathered rock will be eroded.

Naturally speaking, the rate at which limestone dissolves depends on the amount of rainfall and the concentration of carbon dioxide in the water. Chemical weathering is the process that breaks down rock through chemical changes. The most common agents of chemical weathering include water, oxygen, carbon dioxide, and living organisms. Chemical weathering creates holes or soft spots in rock, so the rock breaks apart more easily. Chemical and mechanical weathering often goes hand in hand; mechanical weathering breaks rock into pieces, exposing more surface area to chemical weathering. It someone wants to dissolve a rock manually, Hydrofluoric acid is the answer.
