Answer 1

Answer:

c is the answer. 100% garentee and warranty of answer

Answer 2

Marble statues are corroded or stained when they repeatedly come into c) polluted water is acidic in nature hence it reacts with calcium carbonate

Explanation:

• Byproducts of air and water pollution are acidic.carbon dioxide contributes to this majorly.
• when carbon dioxide dissolves in water ,it forms carbonic Acid
• similarly other acidic byproducts are fromed making polluted water acidic in nature.
• Recorroded or stained when they repeatedly come into contact with poll tify the main reason. n of calcium carbonate to calcium oxide is basic in nature hence it reacts with calcium carbonate is acidic in nature hence it reacts with calciumcarbonate onate dissolves in water to give calcium hydroxide
