\(PTHH:Zn+2HCl\rightarrow ZnCl_2+H_2\)
\(n_{Zn}=\dfrac{26}{65}=0,4\left(mol\right)\)
\(\Rightarrow n_{HCL}=0,4.2:1=0,8\left(mol\right)\);\(n_{H_2}=0,4\left(mol\right)\);\(n_{ZnCl_2}=0,4\left(mol\right)\)
\(m_{HCl}=0,8.36,5=29,2\left(g\right)\)
\(V_{H_2}=0,4.22,4=8,96\left(l\right)\)
\(m_{ZnCl_2}=0,4.136=54,4\left(g\right)\)
