1)Na→Na2O→NaOH→NaNO3 2)Al→Al2O3→AlCl3→Al(OH)3→NaAlO

Question

1)Na→Na2O→NaOH→NaNO3

2)Al→Al2O3→AlCl3→Al(OH)3→NaAlO

Answer 1

1)4Na+ O2=2Na2O

Na2O+H2O=2NaOH

NaOH+HNO3=NaHNO3+H2O

 

 

2)

4Al + 3O2 = 2Al2O3

Al2O3 + 6HCl= 2AlCl3 + 3H2O

AlCl3 + 3NaOH = Al(OH)3↓ + 3NaCl

NaAlO2 + 4HNO3 = NaNO3 + Al(NO3)3 + 2H2O
