1.1. Al + NaOH + H2O ==> NaAlO2 + 3/2H2

nH2(1)=3,36/22,4=0.15(mol)

=> nAl(1)= nH2(1):3/2= 0.15:3/2= 0.1(mol)

2.Mg + 2HCl ==> MgCl2 + H2

3.2Al + 6HCl ==> 2AlCl3 + 3H2

4.Fe + 2HCl ==> FeCl2 + H2

=> \(n_{H_2\left(2,3,4\right)}=\) 10.08/22.4= 0.45(mol)

=> nH2(3)=0.1*3/2=0.15(mol)

MgCl2 + 2NaOH ==> Mg(OH)2 + 2NaCl

AlCl3 + 3NaOH ==> Al(OH)3 + 3NaCl

FeCl2 + 2NaOH ==> Fe(OH)2 + 2NaCl

Fe3O4 + 10HNO3 ==> 3Fe(NO3)3 + NO2 + 5H2O
