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.
• Density: In both solids and liquids, the molecules are held very closely together and therefore their densities are about the same. In gases, there is space
between the molecules.
• Molecular movement and order: The molecules in solids are arranged in a regular pattern that does not allow for diffusion, although does allow for
vibrations. The arrangement of molecules in a liquid, although not completely random, is not completely fixed. Molecules in a gas are randomly arranged and
move very quickly. Gases diffuse quickly in comparison to liquids.
Compressibility and thermal expansion: Since the molecules in solids and liquids are already very close together, applying pressure does not greatly
affect the volume. In contrast, the space between gas molecules allows for a great deal of compressibility. Although temperature changes will cause slight
variations in the volume of a solid or liquid, those variations are negligible compared to the thermal expansion of a gas.

- compound 1 2 3 description Compound 1 is a yellow solid made up of clusters of needle-like crystals. It's a good electrical insulator when solid, but if crushed and dissolved in water, the solution is a good conductor. Compound 2 is a hard light gray solid made up of clusters of cube-shaped crystals. It can easily be ground into a fine powder. If that powder is compressed to form a block, the block is an insulator. However, if the block is moistened slightly, it starts to conduct electricity much better. Compound 3 is a deep red solid with a noticeable unpleasant smell.
