Question

PLEASE ANSWER!!! Sulfuric acid (a component of acid rain) reacts with limestone (calcium carbonate) to produce calcium sulfate and carbon dioxide. This damages buildings and statues made of limestone. Which solution of sulfuric acid will damage these structures more quickly? A. 0.001% B. 0.005% C. 0.010% D. 0.015%

Answer 1

Answer:

The answer is D. 0.015%

Explanation:

That is the concentration of the Sulfuric Acid solution given in mass per mass percentage (w/w%), it means that the solution has 0.015 grams of Sulfuric Acid per 100 grams of solution. If it is compared with C answer, it has 0.005 grams more. Considering the reaction:

$H_{2} SO_{4} + CaCO_{3}$ ⇒ $CaSO_{4} + CO_{2} + H_{2}O$

The more $H_{2} SO_{4}$ (Sulfuric Acid) is present, the more $CaCO_{3}$ (Limestone) is consumed.

Answer 2

Answer:

D is the best choice. Those percentages, are giving you the information about how concentrated are the solutions.  As 0.015 is so concentrated, this solution will damage the structures more quickly
