Ta có: \(n_{Zn}=\dfrac{13}{65}=0,2\left(mol\right)\)
PT: \(Zn+2HCl\rightarrow ZnCl_2+H_2\)
____0,2_____0,4____0,2____0,2 (mol)
a, \(V_{H_2}=0,2.22,4=4,48\left(l\right)\)
b, \(m_{HCl}=0,4.36,5=14,6\left(g\right)\)
c, \(m_{ZnCl_2}=0,2.136=27,2\left(g\right)\)
d, \(CuO+H_2\underrightarrow{t^o}Cu+H_2O\)
___0,2____0,2 (mol)
\(\Rightarrow m_{CuO}=0,2.80=16\left(g\right)\)
