Write the reaction equations: Mg- MgO- Mg (OH) ₂ -MgSO₄

Determine the sequence of the solution, indicate the names of the substances:
1. Magnesium – magnesium oxide – magnesium hydroxide – magnesium sulfate
2. Let us write down the equations of the processes:
2Mg + O2 = 2MgO – compounds, obtained magnesium oxide;
MgO + 2HCl = MgCl2 + H2O – ion exchange, magnesium chloride was formed;
MgCl2 + 2KOH = Mg (OH) 2 + 2KCl – magnesium hydroxide is released during ion exchange;
Mg (OH) 2 + H2SO4 = MgSO4 + 2H2O – obtained magnesium sulfate.
The solution process shows the bond of metals, basic oxides, hydroxides, medium salts.
The product of the chain of transformations, magnesium sulfate, is used in the production of synthetic detergents.
