[imath]n_Y[/imath]=0,08
[imath]m_Y[/imath]=2,34
=> [imath]n_{N_2}[/imath]=0,03, [imath]n_{NO}[/imath]=0,05
=>[imath]n_{N_2} : n_{NO}=3:5[/imath]
a) Gọi x,y là số mol Fe, Zn
[imath]Fe \to Fe^{+3} + 3e[/imath]
x--------------------3x
[imath]Zn \to Zn^{+2} + 2e[/imath]
y----------------------2y
[imath]11N^{+5} +45e \to 5N^{+2} + 6N^{+0}[/imath]
0,11-----------0,45-------0,05-------0,06
56x+65y=10,475
BTe: 3x+2y=0,45
=>x=0,1 ;y=0,075
%Fe=53,46%, %Zn=46,54%
b)
[imath]n_{H^+}[/imath]=0,05.4+0,03.12=0,56=>V=2,24 l
BT H=>[imath]n_{H_2O}[/imath]=0,28
BTKL=>m(muối)=38,375g
