\(Zn+2HCl\rightarrow ZnCl_2+H_2\)
Theo PT: \(n_{Zn}=n_{H_2}=n_{ZnCl_2}=0,2\left(mol\right)\)
=> \(V_{H_2}=0,2.22,4=4,48\left(l\right)\)
\(m_{ZnCl_2}=0,2.136=27,2\left(g\right)\)
Ta có \(n_{Zn}=\dfrac{13}{65}=0.2\left(mol\right)\)
PTHH: \(Zn+2HCl\rightarrow ZnCl_2+H_2\)
0,2---->0,4----->0,2------->0,2(mol)
\(V_{H_2\left(đktc\right)}=0,2\cdot22,4=4,48\left(l\right)\)
\(m_{ZnCl_2}=0,2\cdot\left(65+35,5\cdot2\right)=27,2\left(g\right)\)
