Acid rain's effect on stone is a chemical change. Acid rain can contain hydrochloric acid (HCl), and a stone building can contain calcium carbonate (CaCO3). These two substances react, according to this equation:
2HCl + CaCO3 --> CaCl2 + H2O + CO2
The product calcium chloride (CaCl2) is a salt, and therefore water soluble, so acid rain can literally "eat away" at a stone building, diminishing its aesthetic qualities, and even compromising it structurally over time.

Is acid rain damaging a marble statue a physical change?
false
Is Acid rain damaging a marble statue is a physical chane?
Yes, acid rain damaging a marble statue is considered a physical change. The chemical composition of the marble remains the same, but the surface of the statue is physically eroded by the acidic components in the rain, leading to visible changes on the surface.
Acid rain damaging a marble statue is a physical change?
Acid rain damaging a marble statue is actually a chemical change. The acid reacts with the calcium carbonate in the marble, forming new compounds like calcium sulfate which can dissolve or wear away the statue. This chemical reaction alters the composition of the marble, leading to the visible damage.
What type of weathering causes acid rain?
Chemical weathering causes acid rain. When sulfur dioxide and nitrogen oxides are released into the atmosphere from human activities, they combine with water vapor to form sulfuric acid and nitric acid, which then fall to the earth's surface as acid rain.
Is acid rain weathering or erosion or both?
Acid rain can contribute to both weathering and erosion. Weathering refers to the breakdown of rock materials due to chemical or physical processes, which can be enhanced by acid rain. Erosion, on the other hand, involves the removal and transport of weathered materials by agents like water or wind, which can also be influenced by acid rain.
Is acid rain weathering a marble statue a physical change or a chemical change?
Chemical change
Is Acid rain dissolving paint off a wall a chemical change or physical change?
The process of acid rain dissolving paint off a wall is a chemical change. This is because the acid in the rain reacts with the chemical components of the paint, causing a permanent change in its chemical structure.
Is acid rain corroding gravestones a physical or chemical change?
The corrosion of gravestones due to acid rain is a chemical change. The acid rain reacts with the minerals in the stone, causing a chemical breakdown that results in the degradation of the gravestone material.
Forming acid rain a chemical or physical change?
Forming acid rain is a chemical change because it involves the reaction of sulfur dioxide and nitrogen oxides with water, oxygen, and other chemicals in the atmosphere to produce sulfuric acid and nitric acid.
Example of a physical rather than a chemical change?
when a rock is erodded by wind or waves is a physical change where acid rain eroding a stone figure would be chemical
Is marble dissolves in acid rain physical or chemical change?
Marble dissolving in acid rain is a chemical change. The acid reacts with the calcium carbonate in the marble to form new substances, such as carbon dioxide and water. This chemical reaction alters the composition of the marble, leading to its dissolution.
Is acid rain damaging a marble statue a physical change?
false
Is the Statue of Liberty a physical change or a chemical change?
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.
Is acid rain a chemical or physical change?
acid rain formation is chemical change when oxides of nitrogen or sulphur tri oxide present in the poluted atmosphere combines with rain water and they give respective acid solutions so the rain water become slitely acidic
Is acid rain damaging something a physical change?
Acid rain causing damage to structures, buildings, and vegetation is a chemical change, as it involves a chemical reaction between the acidic rainwater and the materials it comes into contact with. This reaction leads to the degradation and breakdown of the affected surfaces over time.
What are differences between physical and chemical weathering?
physical: water, wind, and temperature chemical: acid rain and rust
When rain evaporates from a side walk is it classified as a chemical or physical change?
physical change
