Answer :

Answer:

calcium carbonate is transformed into calcium sulfate

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
