\(n_{Zn}=\dfrac{m_{Zn}}{M_{Zn}}=\dfrac{6,5}{65}=0,1\left(mol\right)\)
PTHH: \(Zn+2HCl\rightarrow ZnCl_2+H_2\)
1 mol _ 2 mol _ 1 mol _ 1 mol
0,1 mol _ 0,2 mol _ 0,1 mol _ 0,1 mol
\(n_{H_2}=\dfrac{n_{Zn}.1}{1}=0,1\left(mol\right)\)
\(V_{H_2}=n_{H_2}.22,4=0,1.22,4=2,24\left(l\right)\)
\(n_{HCl}=\dfrac{n_{Zn}.2}{1}=0,2\left(mol\right)\)
\(m_{HCl}=n_{HCl}.M_{HCl}=0,2.36,5=7,3\left(g\right)\)
