Describe the chain of reactions: Mg = MgSo4 = Mg (OH) 2 = MgO = MgCO3 = CO2

Let’s carry out the solution of the transformation chain for inorganic substances:
Mg + H2SO4 = MgSO4 + H2 – ОВР, gaseous hydrogen and magnesium sulfate are released;
MgSO4 + 2KOH = Mg (OH) 2 + K2SO4 – exchange, magnesium hydroxide was obtained;
Mg (OH) 2 = MgO + H2O – decomposition, occurs when heated, magnesium oxide is released;
MgO + CO2 = MgCO3 – compounds, magnesium carbonate was formed;
MgCO3 = MgO + CO2 – decomposition, possible when heated, carbon dioxide evolved.
The above reactions confirm the connection of metals, salts, oxide bases.
