1.As a result of the reaction between chlorine and hydrogen, hydrogen chloride is formed.
H2 + Cl2 = 2HCl.
2. The reaction between iron and hydrochloric acid proceeds with the formation of ferric chloride and hydrogen.
Fe + 2HCl = FeCl2 + H2.
3. The substitution reaction between magnesium and iron chloride proceeds with the formation of iron and magnesium chloride.
FeCl2 + Mg = MgCl2 + Fe.
4. Magnesium chloride, reacting with sodium hydroxide, form magnesium hydroxide and sodium chloride.
MgCl2 + + 2NaOH = Mg (OH) 2 + 2NaCl.
5. The decomposition of magnesium hydroxide proceeds with the formation of magnesium oxide and water.
Mg (OH) 2 = MgO + H2O.
5. Magnesium oxide and sulfur (IV) oxide react to form magnesium sulfite.
MgO + SO2 = MgSO3.
