a) PTHH: \(Zn+2HCl\rightarrow ZnCl_2+H_2\uparrow\)
b+c) Ta có: \(n_{Zn}=\dfrac{13}{65}=0,2\left(mol\right)\)
\(\Rightarrow\left\{{}\begin{matrix}n_{HCl}=0,4\left(mol\right)\\n_{H_2}=0,2\left(mol\right)\end{matrix}\right.\) \(\Rightarrow\left\{{}\begin{matrix}m_{HCl}=0,4\cdot36,5=14,6\left(g\right)\\V_{H_2}=0,2\cdot22,4=4,48\left(l\right)\end{matrix}\right.\)
d) PTHH: \(H_2+CuO\underrightarrow{t^o}Cu+H_2O\)
Theo PTHH: \(n_{Cu}=n_{H_2}=0,2\left(mol\right)\) \(\Rightarrow m_{Cu}=0,2\cdot64=12,8\left(g\right)\)
