Make up the reaction equation: CH4 → CO2 → C6H12O6; CH4 → H2O → O2 → Fe2O3; H2O → H2 → HCl → AlCl3.

Let’s implement the solution:

Methane – carbon monoxide (4) – glucose
СН4 + 2О2 = СО2 + 2Н2О + Q – combustion, carbon dioxide is released;

6СО2 + 6Н2О = С6Н12О6 + 6О2 – photosynthesis, glucose was obtained.

Methane – water – oxygen – iron oxide (3)
CH4 + 2O2 = CO2 + 2H2O – methane combustion process;

H2O (electric current) = 2H2 + O2 – decomposition of water under the influence of el. current;

4Fe + 3O2 = 2Fe2O3 – OBP, iron oxide was obtained (3).

Water – hydrogen – hydrogen chloride – aluminum chloride
Н2О (electric current) = 2Н2 + О2 – decomposition of water, hydrogen is obtained;

Н2 + Сl2 = 2HCl – compounds, hydrogen chloride was formed;

6HCl + 2Al = 2AlCl3 + 3H2 – OBP, aluminum chloride was obtained.
