Zn + 2HCl --> ZnCl2 + H2
\(n_{Zn}=\dfrac{26}{65}=0,4\left(mol\right)\)
=> \(m_{ZnCl_2}=0,4.136=54,4\left(g\right)\)
\(V_{H_2}=0,4.22,4=8,96\left(l\right)\)
\(nZn=\dfrac{26}{65}=0,4mol\)
\(Zn+2HCl\rightarrow ZnCl_2+H_2\)
0,4-->0,8----->0,4------->0,4
\(mZnCl_2=136.0,4=54,4g\)
\(VH_2=0,4.22,4=8,96lít\)
