Make the equation: Ca → CaC2 → C2H2 → CO2 → C6 H12 O6 → C2H5OH → C2H4

1) When calcium interacts with carbon, calcium carbide is formed:

Ca + 2C → CaC2;

2) Calcium carbide reacts with water, it turns out – calcium hydroxide and acetylene:

CaC2 + 2H2O → Ca (OH) 2 + C2H2;

3) Acetylene reacts with oxygen, we get carbon oxide (IV) and water:

2C2H2 + 5O2 → 4CO2 + 2H2O;

4) Carbon oxide (IV) reacts with water, forms – oxygen and glucose:

6H2O + 6CO2 → 6O2 + C6H12O6;

5) Glucose decomposes into ethanol and carbonic oxide (IV):

C6H12O6 → 2C2H5OH + 2CO2;

6) Ethanol decomposes into ethane and water:

С2H5OH → C2H4 + H2O.
