(II) H2O2 -------> H2O + O2
(III) Mg (OH)2 + HCI -------> MgCI2 + H2O
(IV) Fe + O2 ------> Fe2O3
(V) Al (OH)3 ------> Al2O3 + H2O
(VI) Al2(SO4)3 + NaOH Al (OH)3 + Na2SO4

Answer 1

Answer:

1) 4Na + O2 gives 2Na2o

here is the answer of the first one

Answer 2

Answer:

• 4Na+ O2 -- 2Na2O
• 2H2O2 -- 2H20 + O2
• Mg(OH)2 + 2HCL -- MgCl2 + H2O
• 2Fe + 3O2 -- Fe2O3
• 2Al(OH)3-- Al2O3 + 3H2O
• Al2(SO4)3 + NaOH -- Al(OH)3 + Na2SO4
