Acid rain weathering a marble statue physical or chemical change. When sulfurous sulfuric and nitric acids in polluted air and rain react with the calcite in marble and limestone the calcite dissolves. These two substances react according to. Stone surface material may be lost all over or only in spots that are more reactive. No its a chemical change because the acid in the rain reacts with the copper in the statue having a reaction oxidizing it and turning it green.

Occurs when chemical reactions dissolve or change the minerals in rocks c. When sulfurous sulfuric and nitric acids in polluted air react with the calcite in marble and limestone the calcite dissolves. Acid rain harms fish and trees but it also makes chemical weathering. Ice wedging in rock.

Acid rain can contain hydrochloric acid hcl and a stone building can contain calcium carbonate caco3.

How does acid precipitation affect marble and limestone buildings. Marble with its larger crystals and smaller pores can attain a high polish and is thus preferred for monuments and statues. Marble like all calcareous rocks is particularly sensitive to degradation by acid chemicals and to weathering.

Favorite answer it is a chemical change because the acid sulfuric and nitric in the rain will react with the marble caco3 to produce carbon dioxide water and calcium sulfate h2so4 caco3. In exposed areas of buildings and statues we see roughened surfaces removal of material and loss of carved details.
