This is a chemical equation representing the reaction when calcium carbonate (CaCO3) reacts with calcium hydroxide (Ca(OH)2), carbon dioxide (CO2), sodium bicarbonate (NaHCO3), and sodium chloride (NaCl).

The balanced equation for this reaction is:

CaCO3 + Ca(OH)2 + 2CO2 + 3NaHCO3 + 2NaCl → 2Ca + 2H2O + 3CO2 + 3NaCl

This reaction results in the formation of calcium, water, carbon dioxide, and sodium chloride.
