(a) List one observation that shows a chemical change is occurring in the diagram.
(b) What environmental problem in New York makes limestone a poor choice to use outside of a building?
Please help me.... ThanksA diagram shows how crushed limestone in a test tube reacts when acid is added.?a. carbon dioxide is released effervescently as a fizzing when the acid is added to the limestone.
b. limestone buildings are attacked by acid rain, which corrodes them just like the limestone in the test tube, but in a less concentrated form.
New York has acid rain.
