This is a series of chemical reactions involving the compounds calcium bicarbonate (Ca(HCO3)2), calcium carbonate (CaCO3), calcium oxide (CaO), calcium carbide (CaC2), acetylene (C2H2), benzene (C6H6), and carbon dioxide (CO2).

Ca(HCO3)2 -> CaCO3 + CO2 + H2
Calcium bicarbonate decomposes into calcium carbonate, carbon dioxide, and water.

CaCO3 -> CaO + CO
Calcium carbonate decomposes into calcium oxide and carbon dioxide.

CaC2 + 2H2O -> C2H2 + Ca(OH)
Calcium carbide reacts with water to produce acetylene and calcium hydroxide.

2C2H2 + 5O2 -> 4CO2 + 2H2
Acetylene combusts in the presence of oxygen to produce carbon dioxide and water.

2C6H6 + 15O2 -> 12CO2 + 6H2
Benzene combusts in the presence of oxygen to produce carbon dioxide and water.

Overall, the reactions involve the decomposition of calcium bicarbonate and calcium carbonate, the formation of acetylene from calcium carbide, and the combustion of acetylene and benzene to produce carbon dioxide and water.
