a) 2Mg + O2 => 2MgO;
MgO + 2HNO3 => Mg (NO3) 2 + H2O;
Mg (NO3) 2 + 2KOH => Mg (OH) 2 + 2KNO3;
Mg (OH) 2 => MgO + H2O;
MgO + 2HCl => MgCl2 + H2O.

b) 4Al + 3O2 => 2Al2O3;
Al2O3 + 3H2SO4 => Al2 (SO4) 3 + 3H2O;
Al2 (SO4) 3 + 6KOH => 2Al (OH) 3 + 3K2SO4;
2Al (OH) 3 => Al2O3 + 3H2O;
Al2O3 + 6HCl => 2AlCl3 + 3H2O.
