      TACC123

      Oxygen

      MnO2

      2H2O2 = O2 + 2H2O

      Carbon Dioxide

      2HCl + CaCO3 = CaCl2 + H2O + CO2

      There is none for limestone

      ScienceExam

      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)."

      Acid/CarbonateReaction

      Balanced chemical equation

      2HCL + CaCo₃ -----------> CaCl₂ + H₂0 +CO₂

      Word Equation

      Hydrochloric acid + calcium carbonate ---------> calcium chloride +water + carbon dioxide
