a,\(n_{Zn}=\dfrac{6,5}{65}=0,1\left(mol\right)\)
PTHH: Zn + 2HCl → ZnCl2 + H2
Mol: 0,1 0,1 0,1
b,\(m_{ZnCl_2}=0,1.136=13,6\left(g\right)\)
c,\(V_{H_2}=0,1.22,4=2,24\left(l\right)\)
a)PTHH: \(Zn+2HCl\rightarrow ZnCl_2+H_2\)
b) \(n_{Zn}=\dfrac{6,5}{65}=0,1\left(mol\right)\)
\(n_{ZnCl_2}=n_{Zn}=0,1\left(mol\right)\)
\(\Rightarrow m_{ZnCl_2}=n.M=0,1.136=13,6\left(g\right)\)
c) \(n_{H_2}=n_{Zn}=0,1\left(mol\right)\)
\(V_{H_2}=n.22,4=0,1.22,4=2,24\left(l\right)\)
\(n_{Zn}=\dfrac{6,5}{65}=0,1\left(mol\right)\)
a) Pt : \(Zn+2HCl\rightarrow ZnCl_2+H_2|\)
1 2 1 1
0,1 0,1 0,1
b) \(n_{ZnCl2}=\dfrac{0,1.}{1}=0,1\left(mol\right)\)
⇒ \(m_{ZnCl2}=01,.136=13,6\left(g\right)\)
c) \(n_{H2}=\dfrac{0,1.}{1}=0,1\left(mol\right)\)
\(V_{H2\left(dktc\right)}=01,.22,4=2,24\left(l\right)\)
