Write the reaction equation: C2h4-c2h5cl-c2h5oh-c2h5-o-c2h5-co2-caco3

1. Reaction of ethylene hydrohalogenation.
C2H4 + HCl = C2H5Cl.
2. Reaction of ethylene chloride with an aqueous alkali solution.
C2H5Cl + NaOH = C2H5OH + NaCl.
3. The reaction of the formation of diethyl ether using an acid catalyst.
2C2H5OH = C2H5-O-C2H5 + H2O.
4. Oxidation reaction.
C2H5-O-C2H5 + 6O2 = 4CO2 + 5H2O.
5. Obtaining calcium carbonate.
CO2 + CaO = CaCO3.
