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.
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
