what are the oxygen, carbon dioxide, and limestone chemical equations

TACC123 — 31/05/16
Oxygen MnO2 2H2O2 = O2 + 2H2O Carbon Dioxide 2HCl + CaCO3 = CaCl2 + H2O + CO2 There is none for limestone

Limestone is Calcium Carbonate .... "CaCO3". "Limestone is a sedimentary rock composed largely of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3)."
