Make an equation: Mg-Mgo-Mgso4-Mg (OH) 2-Mgcl2-Mg

1) 2Mg + O2 = 2MgO (when magnesium interacts with oxygen, magnesium oxide is formed);

2) MgO + H2SO4 = MgSO4 + H2O (when magnesium oxide interacts with sulfuric acid, magnesium sulfate and water are formed);

3) MgSO4 + 2KOH = Mg (OH) 2 + K2SO4 (when magnesium sulfate interacts with potassium hydroxide, magnesium hydroxide and potassium sulfate are formed);

4) Mg (OH) 2 + 2HCl = MgCl2 + 2H2O (when magnesium hydroxide interacts with hydrochloric acid, magnesium chloride and water are formed);

5) MgCl2 = Mg + Cl2 (when heated, magnesium chloride decomposes into magnesium and chlorine).
