PTHH :
Zn + 2HCl ----- > ZnCl2 + H2
Số mol Zn : nZn = \(\frac{5,6}{65}\) (mol)
Theo PTHH : nZn = nH2 = \(\frac{5,6}{65}\) (mol)
VH2 = \(\frac{5,6}{65}\) . 22,4 = 1,93 (l)
Zn+2HCl-->ZnCl2+H2
0,1----------------------0,1 mol
nZn=5,6\65=0,1 mol
=>mH2=0,1.22,4=2,25 l
\(PTHH:Zn+2HCl\rightarrow ZnCl_2+H_2\)
\(n_{Zn}=\frac{5,6}{65}=0,09\left(mol\right)\)
Theo PT: \(n_{H2}=n_{Zn}=0,09\left(mol\right)\)
\(\Rightarrow V_{H2}=0,09.22,4=2,016\left(l\right)\)
PT:Zn+2HCl→ZnCl2+H2
.....0,09----------------0,09 mol
nZn=5,6\65=0,09(mol)
-->VH2=0,09.22,4=2,016(l)
