1. The reactivity of marble with sulfuric acid seems curiously out of line with all of the other observations. If you observed carefully, you may have seen a brief burst of gas bubbles, which quickly stopped. This is because one product of the reaction, calcium sulfate (CaSO4), is insoluble and provides a protective coating on the marble, which slows the reaction dramatically. Does this mean that acid rain containing sulfuric asid should have little or no effect on statues and buildings made of marble? Explain your answer. 2. Iron reacts readily with acid, but is also an important structural material for buildings. Based on your observations, how effective are zinc or nickel coatings as a protection for iron against acid rain? 3. Copper has been important since ancient times as a building material used in roofing structures. On the basis of your observations, is copper a good material for this purpose? Note: You may have observed a green color on the roofs of public buildings or monuments such as the Statue of Liberty. This is a form of copper carbonate, formed by slow reaction of copper with nitric acid plus carbon dioxide from the atmoseh
