Fe + O2 = Fe3O4
Fe3O4 + HCl = FeCl2 + FeCl3 + H2O
FeCl2 + NaOH = Fe(OH)2 + NaCl
FeCl3 + NaOH = Fe(OH)3 + NaCl
Fe(OH)2 + O2 + H2O = Fe(OH)3
Fe(OH)3 = Fe2O3 + H2O
=> A=Fe3O4;B=FeCl2;C=FeCl3;D=Fe(OH)2;E;Fe(OH)3;G=NaCl;F=Fe2O3

1)
\(n_{Zn}=\dfrac{13}{65}=0,2\left(mol\right)\\ A_{Zn}=0,2.6.10^{23}=12.10^{23}\left(\text{nguyên tử}\right)\)
Để \(A_{Cu}=A_{Zn}\Rightarrow n_{Cu}=n_{Zn}=0,2\left(mol\right)\)
\(\Rightarrow m_{Cu}=0,2.64=12,8\left(g\right)\)
