A heartburn tablet (like Tums or Rolaids) contains food grade calcium carbonate (s) to neutralize stomach acid, HCl(aq). Calcium carbonate is part of the rock cycle in the world of geology and is a type of sedimentary rock called limestone, that forms in oceans. The White Cliffs of Dover England and the Seven Sisters of Sussex England shown in the picture here are also made of calcium carbonate, specifically chalk. Chalk is a pure white limestone formed from the remains of tiny marine organisms (plankton) that lived and died in clear warm seas that covered much of Britain around 70 to 100 million years ago. Do not eat chalk to neutralize stomach acid as it is not purified food grade! Write the balanced molecular equation including phases for solid calcium carbonate reacting with hydrobromic acid. Then write the Full ionic equation including phases. Finally, write the net ionic equation including phases.
