\(a) Zn + 2HCl \to ZnCl_2 + H_2\\ b) n_{H_2} = n_{Zn} = \dfrac{13}{65} = 0,2(kmol)\\ V_{H_2} = 0,2.22,4 = 4,48(m^3)\\ c) 2H_2 + O_2 \xrightarrow{t^o}2H_2O\\ n_{H_2O} = n_{H_2} = 0,2(kmol)\\ m_{H_2O} = 0,2.18 = 3,6(kg)\)
a+b) PTHH: \(Zn+2HCl\rightarrow ZnCl_2+H_2\uparrow\)
Ta có: \(n_{Zn}=\dfrac{13}{65}=0,2\left(mol\right)=n_{H_2}\) \(\Rightarrow V_{H_2}=0,2\cdot22,4=4,48\left(l\right)\)
c) PTHH: \(H_2+\dfrac{1}{2}O_2\xrightarrow[]{t^o}H_2O\)
Theo PTHH: \(n_{H_2O}=n_{H_2}=0,2\left(mol\right)\)
\(\Rightarrow m_{H_2O}=0,2\cdot18=3,6\left(g\right)\)
