\(5,41g\left\{{}\begin{matrix}Al\\Zn\end{matrix}\right.+HCl->\left\{{}\begin{matrix}AlCl3\\ZnCl2\end{matrix}\right.+H2\)
Ta có :
\(\left\{{}\begin{matrix}27x+65y=5,41\\133,5x+136y=17,48\end{matrix}\right.\Leftrightarrow\left\{{}\begin{matrix}x=0,08\\y=0,05\end{matrix}\right.\)
Bảo toàn e :
\(3x+2y=2.nH2\)
\(\Rightarrow nH2=0,17\left(mol\right)\)
\(\Rightarrow V=0,17.22,4=3,808\left(l\right)\)
