\(n_{H_2}=\frac{8,512}{22,4}=0,38\left(mol\right)\)
PTHH: Zn + 2HCl --> ZnCl2 + H2
a -------------------------> a (mol)
2Al + 6HCl ---> 2AlCl3 + 3H2
b ----------------------------> 1,5b (mol)
=> \(\left\{{}\begin{matrix}65a+27b=16,24\\a+1,5b=0,38\end{matrix}\right.\)
=> \(\left\{{}\begin{matrix}a=0,2\left(mol\right)\\b=0,12\left(mol\right)\end{matrix}\right.\)
=> \(\left\{{}\begin{matrix}m_{Zn}=65.0,2=13\left(g\right)\\m_{Al}=27.0,12=3,24\left(g\right)\end{matrix}\right.\)
Mk làm câu kia r nên mk xóa câu này nha
