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
Explanation:
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:
[tex]H_{2} SO_{4} + CaCO_{3}[/tex] ⇒ [tex]CaSO_{4} + CO_{2} + H_{2}O[/tex]
The more [tex]H_{2} SO_{4}[/tex] (Sulfuric Acid) is present, the more [tex]CaCO_{3}[/tex] (Limestone) is consumed.
