Limestone is basically calcium carbonate. *All* acids will slowly cause the surface of limestone to dissolve thus eroding the surface. The stronger the acid, the quicker the dissolution. Acids based on sulfur, such as sulfurous or sulfuric acids are very harmful to limestone.

How does carbon dioxide in the air weather rocks?
Carbonic acid reacts chemically with limestone, which is observed as weathering. As such, carbonic acid weathering is a chemical, not physical, change.
How Joseph Black used evidence from his experiments to show that animals produce carbon dioxide?
Joseph Black discovered carbon dioxide or fixed air was released by limestone when heated. He went on to identify it in the atmosphere and found it could not support animal life. He then found humans exhale the substance by collecting air samples.
What is the chemical equation for limestone being heated strongly in air?
CaCO3 -------> CaO + CO2
When a substance changes state is it a physical or a chemical change?
It undergoes a physical change... IE: ice and steam have the same chemical makeup (H20). To undergo a chemical change, the substance has to interact with something else. However, this can be a trick question because if something is heated in a real world setting then it could possible react with oxygen, nitrogen, carbon dioxide, or another trace gas in air.
What is the substance in the air that causes copper to turn black when in contact with fire?
The substance in the air is oxygen. Copper + oxygen= copper oxide.
Why do they have to change the limestone statues on the cathedral every 200 years?
Carbon dioxide in the air combines with water vapor, creating an acidic substance which heavily weathers away the limestone, making the statues unsightly.
What are limestone caves made out of?
Air! They are voids IN limestone formed by dissolution by water.
What fog is made of what substance alreadypresent in the air?
it is energy air
What is carlsbad cavern made up of?
Mainly, fresh air surrounded by limestone! A cave is a void, or set of voids, formed within limestone.
Why rusting is a chemical change and not a physical change?
Rusting is a chemical change because the metal is reacting with air and changing into a new substance.
Why is air a substance?
air is a substance because air is a gas and a gas is a substance.
What is formed when limestone is heated?
When heated, limestone forms two different things. It forms both calcium oxide and carbon dioxide. This occurs because limestone is made up of calcium carbonate.
What chemical change is it when Magnesium burns in air?
when magnesium burns in air a white powder called magnesium oxide is formed which is a new substance this is the chemical change
How much air pressure equals 120 psi of water?
Pressure doesn't change when you change substance, 120 PSI in water equals 120 PSI in air.
What two physical properties of matter can change according to how much of the substance is in an object?
a book and air
Does the mass of a substance change after a chemical reaction changes the substance from a liquid to a solid?
No. According the the law of conservation of Mass, it would be physically impossible for the mass of the substance to change. However, it is possible for the volume (amount of space taken up by the substance) to change, as well as it's weight (if gasses are released or molecules in the air are involved).
Why is air a pure substance?
Air is not a pure substance.
