Question

Over many years a limestone surface is exposed to slightly acidic rain. Which result is likely to occur in the limestone

Answer 1

calcium carbonate is transformed into calcium sulfate

Step-by-step explanation:

Limestone stones are formed by calcium carbonate (Ca Co3), when acid rain falls with a little H2SO2, a chemical reaction of the type

Ca Co3 + H2SO4 → CO2 + H2O + CaSo4

Calcium sulfate is much weaker than alatium carbonate, which is why the stone tends to break under its weigh
