\(n_{Zn}=\dfrac{6,5}{65}=0,1\)
\(Zn+2HCl\rightarrow ZnCl_2+H_2\)
Theo pt:\(n_{H_2}=n_{Zn}=0,1\left(mol\right)\)
\(V_{H_2}=0,1.22,4=2,24\left(l\right)\)
Theo pt: \(n_{HCl}=2n_{Zn}=0,2\left(mol\right)\)
\(V_{HCl}=\dfrac{0,2}{1}=0,2\left(l\right)\)
nZn = \(\dfrac{6,5}{65}\)= 0,1 mol
a)
Zn +2 HCl -> ZnCl2 + H2
0,1->0,2.................->0,1
b)VH2 = 0,1 . 22,4 = 2,24(l)
c) VHCl(1M) = \(\dfrac{0,2}{1}\) = 0,2 (l)
